# Introduction
b14g (aka Bitcoin Restaking)
## What is b14g?
**b14g** is a **BTCFi (Bitcoin Finance) hub,** a foundational layer that makes **Bitcoin productive** across multiple chains.
#### What it does
b14g connects **Bitcoin holders**, **protocol token holders**, and **Bitcoin-aligned chains** (like Core, Babylon, and Stacks) through three main components:
1. **BTC Self-Custodial Staking:** lets BTC holders stake their Bitcoin safely (without giving up custody) to help secure Bitcoin-aligned networks and earn yield.
2. **BTCFi Vaults:** create yield strategies combining BTC + protocol tokens (dual-staking), offering competitive returns with transparent risk control.
3. **Merge Marketplace:** an on-chain marketplace where BTC stakers and token stakers match with each other to co-stake, share yield, and increase capital efficiency.
#### Why it matters
* Today, Bitcoin is mostly idle capital, 60% hasn’t moved in a year.
* Each BTCFi chain runs its own isolated staking model, causing fragmentation and inefficiency.
* b14g unifies them into one marketplace and plug-and-play dual-staking layer so new chains can adopt Bitcoin security **without reinventing the wheel**.
#### The Vision
To turn Bitcoin from a **static store of value** into **productive capital** that secures and powers the next wave of decentralized networks — **the BTCFi economy.**

# Problem Statement
Problem Statement: The Need for a BTCFi Hub
Bitcoin has become the world’s most trusted store of value, but not its most productive asset. Over **$2 trillion worth of BTC** sits untouched, with more than **90% held idle in wallets** earning nothing.
This stability shows conviction, but it also reveals a structural inefficiency: Bitcoin capital remains unproductive, while emerging Bitcoin-aligned ecosystems struggle to attract sustainable liquidity and security.
***
### **1. The Current State: Idle Capital, Isolated Systems**
**Bitcoin holders** want yield, but they lack safe, organic ways to earn it.
**Bitcoin-aligned chains**, like Core, Babylon, and Stacks, need BTC participation to secure their networks and grow.
Yet between them lies a disconnect.
Each chain has built its own version of Bitcoin staking or dual-staking:
* Different smart contracts, validator rules, and reward systems.
* No unified way for BTC holders to participate across multiple chains.
* Users must manually bridge, re-stake, or swap tokens to chase yield.
The result: **fragmented liquidity** and **poor capital efficiency.**
***
### **2. The Incentive Problem: Why Early BTC Staking Fails**
Early Bitcoin staking models followed a familiar pattern:
> BTC stakers stake BTC → earn native tokens → immediately sell rewards.
Since rewards are paid in volatile native tokens, stakers have little reason to hold them, leading to:
* **Continuous sell pressure** on protocol tokens.
* **Inflationary emissions** that drain treasury resources.
* **No long-term alignment** between BTC holders and the protocol.
In short, existing BTCFi systems are **built on incentives to exit, not to stay.**
***
### **3. The Dual-Staking Solution — But Fragmented**
**Dual-staking** emerged to fix this.\
By requiring BTC stakers to also stake a protocol’s token, both sides now share incentives and yield.\
This approach:
* Gives **real utility** to protocol tokens.
* Reduces **sell pressure**.
* Aligns **BTC security** with network growth.
However, dual-staking today is **isolated** per chain:
* Core, Babylon, Stacks, and others each use unique logic, tokenomics, and liquidity pools.
* There’s **no shared marketplace** for BTC and token stakers to meet.
* Every new chain must build its own staking layer from scratch.
***
### **4. The Missing Layer: A Coordination Hub for BTCFi**
What the Bitcoin ecosystem needs isn’t another isolated staking protocol, it needs **a coordination layer** that:
1. **Unifies** BTC liquidity across chains.
2. **Simplifies** participation for BTC holders and token stakers.
3. **Standardizes** dual-staking infrastructure for new chains.
***
### **5. Why This Matters**
Without this layer:
* BTC remains unproductive capital.
* Bitcoin-aligned chains compete for liquidity instead of sharing it.
* Protocols rely on inflationary token rewards to attract users, an unsustainable model.
With this layer, the **b14g BTCFi Hub,** Bitcoin can evolve from a passive store of value into the foundation of a productive, yield-generating financial system.
***
### **6. Summary**
| Problem | Consequence | Opportunity |
| ------------------------------------------ | ----------------------------------- | --------------------------------------------------- |
| BTC is idle, unproductive capital | $2T in capital not generating yield | Activate BTC through secure, self-custodial staking |
| Early BTC staking rewards are inflationary | Sell pressure, no alignment | Introduce dual-staking with shared incentives |
| Dual-staking is fragmented across chains | Low efficiency, user friction | Create a unified dual-staking marketplace |
| New chains rebuild infrastructure | High cost, slow adoption | Offer plug-and-play dual-staking layer |
# Untapped market
Untapped Market Opportunity: The Rise of BTCFi
Bitcoin is the largest, most trusted, and most underutilized asset base in crypto. BTCFi is the next trillion-dollar opportunity — but it’s fragmented.
**b14g** solves this fragmentation by providing the infrastructure layer that unites BTC liquidity, aligns incentives, and activates real Bitcoin yield across every chain.
***
### **1. The Big Picture — Bitcoin’s Sleeping Capital**
Bitcoin is the world’s largest on-chain asset base, yet the least productive.
* **Market cap:** \~$2.4 trillion
* **Idle capital:** \~60% of BTC hasn’t moved in over 12 months (Glassnode)
* **Active on-chain BTC:** < 2% participating in DeFi or staking
* **BTCFi penetration rate:** < 0.5%
While Ethereum transformed idle ETH into productive capital via DeFi and staking, **Bitcoin has yet to experience its “yield unlock” moment.**
***
### **2. The BTCFi Inflection Point**
The ecosystem is shifting fast:
* **CoreDAO** — brought BTC staking to Satoshi Plus consensus (\~4.7K BTC staked)
* **Babylon** — enables native BTC time-locks for chain security (\~55.6K BTC staked)
* **Stacks** — introducing sBTC and PoX upgrades for smart contract BTC use
* **Bitlayer / Mezo / Botanix** — building Bitcoin L2s with DeFi primitives
Each of these networks needs one thing: **BTC holders willing to participate and stake securely.**
Yet, all are fighting over the same small base of BTC users, in **siloed systems**, without a shared coordination layer.
This is the **market gap** b14g is designed to fill.
***
### **3. The Untapped Opportunity — Building the BTCFi Hub**
#### **Total Addressable Market (TAM)**
| Layer | Market Size | Description |
| -------------------------------- | ----------------- | ------------------------------------------ |
| Bitcoin On-chain Capital | \~$2 Trillion | Total BTC value available for activation |
| Addressable BTCFi Capital (1–5%) | $1 Trillion+ | BTC holders seeking safe, productive yield |
| Staking & DeFi Yield Market | $500+ Billion TVL | Comparared with ETH staking rate (28%) |
We're after a $508B market opportunity.
> Even **capturing 0.5%** of idle BTC = **$10B+ in potential deposits,** and b14g aims to be the **main routing hub** for this flow.
***
### **4. Market Gap — What Doesn’t Exist Yet**
| Category | Current Solutions | Limitations | Gap b14g Fills |
| -------------------------- | ----------------------------------- | ---------------------------------------- | ------------------------------------------------------------------------------ |
| **BTC-native yield** | None | Bitcoin protocol doesn’t support staking | Introduces non-custodial BTC staking and restaking via Core, Babylon modules |
| **Dual-staking systems** | CoreDAO, Babylon, Stacks (isolated) | Each chain operates separately | Unified dual-staking marketplace + SDK layer |
| **BTC yield products** | CeFi, bridges, synthetic strategies | Custodial, opaque, high-risk | On-chain, transparent BTCFi Vaults. Sustainable yields from securing networks. |
| **Liquidity coordination** | None | Users must bridge or restake manually | Merge Marketplace automates yield routing |
b14g is positioned as the **“Uniswap + Lido”** of BTCFi — a neutral liquidity layer coordinating Bitcoin yield across chains.
***
### **5. Timing — Why Now**
| Trend | Signal |
| -------------------------- | --------------------------------------------------------------- |
| **BTCFi narrative** | Dominating 2025 cycle (Core, Babylon, Stacks all mainnet-ready) |
| **Bitcoin L2 boom** | 15+ Bitcoin L2s launched in 2024–2025 |
| **Institutional interest** | ETFs approved, on-chain BTC adoption rising |
| **Regulatory readiness** | BTC seen as commodity-grade collateral |
| **User behavior** | BTC holders seeking native yield without custody risk |
> Bitcoin’s liquidity is waking up, but it needs coordination.\
> b14g is entering **just before mass BTCFi adoption**, positioning itself as the **first neutral marketplace** for staking liquidity.
***
### **6. Strategic Positioning — The b14g Advantage**
| Advantage | Explanation |
| ----------------------------- | ---------------------------------------------------------------------------------------------- |
| **Chain-agnostic** | Works across Core, Babylon, Stacks, and future BTCFi ecosystems |
| **Non-custodial** | BTC always stays under user control |
| **Plug-and-play integration** | Chains can enable dual-staking instantly via SDK |
| **Composability** | Vaults integrate with DeFi protocols, lending, and yield aggregators |
| **Liquidity Network Effect** | Each new chain onboarded increases network liquidity and yield efficiency for all participants |
***
### **7. Market Expansion Roadmap**
| Phase | Focus | Impact |
| ---------------------------------------------- | ----------------------------------------------- | --------------------------------------------- |
| **Phase 1 — Activate BTC Yield** | Onboard BTC holders via vaults & staking | Capture early liquidity |

### **3. BTCFi Vaults**
> *Yield infrastructure for dual-staking and DeFi strategies.*
* Smart-contract-based vaults that combine **BTC and partner tokens** (e.g., CORE, BABY, STX) to earn shared rewards.
* Each vault enforces allocation logic: BTC is secured via time-locks; tokens are delegated to network validators or liquidity pools.
* Supports **risk-adjusted yield strategies** (e.g., safe vaults, leveraged vaults, stablecoin-backed vaults).
* Emits **b14g Points** as reward metrics for future cross-chain incentive distribution.
**Example Vaults:**
* `dualCORE Vault` — CORE lst for dual-staking
* `coBABY Vault` — BABY lst for co-staking
* `dualSTX Vault` — STX lst for dual-staking
**Vault Architecture Stack:**
* Smart Contracts (EVM-compatible, Cosmwasm)
* Yield Router (APY optimizer)
* Oracle & Validator Registry (APR data feed)
* b14g Indexer (cross-chain position tracking)

[dualCORE - Liquid Staking](/products/for-core-holders/dualcore-liquid-staking)
{% endcontent-ref %}
### **4. Merge Marketplace**
> *Unifying BTC and token stakers into one marketplace.*
* A **dual-staking matching engine** where BTC stakers post “orders” and token stakers match them.
* Works like an **on-chain orderbook** for yield: matching BTC and token capital in real time based on yield preferences, duration, and risk score.
* Supports both **manual participation** (for retail) and **automated routing** (for protocols and aggregators).
* Fully transparent and composable — other dApps can integrate marketplace liquidity via API or SDK.
**Technical Modules:**
* Matching Engine Smart Contracts
* Order Registry & Indexer
* Yield Router & Fee Module
* Marketplace SDK for chain partners

# Self-Custodial Bitcoin Staking
Trustless BTC staking, earning yield directly from your Bitcoin without wrapping or giving up custody.
## **Overview**
**Self-Custodial BTC Staking** is the foundation of b14g’s BTCFi architecture. It allows Bitcoin holders to **stake their BTC directly from their own wallets** to secure Bitcoin-aligned chains — without wrapping, bridging, or giving up custody.
This mechanism combines Bitcoin’s **native timelock script** with staking proofs verification on connected networks, creating the first truly **trustless, yield-generating** staking model for BTC.
**Key Feature:**
* Your BTC never leaves Bitcoin.
* The yield you earn comes from providing real economic security to Bitcoin-aligned networks.
***
## **How It Works**
### **1. Timelock Mechanism**
A **Bitcoin Timelock** is a feature that allows you to lock your Bitcoin based on time-based conditions. Think of it like a digital “safe”, you can put your BTC inside and set a rule that says *“only open at 3PM today”* or *“open in 5 hours”*
Timelocks are an important part of how **self-custodial Bitcoin staking** or **cross-chain security mechanisms** work. They make sure that your BTC stays locked and provable on the Bitcoin network during a staking or bonding period, and automatically becomes spendable again when that period ends.
#### Types of Timelocks: CLTV vs CSV
Bitcoin supports two main types of timelock scripts: **CLTV** (CheckLockTimeVerify) and **CSV** (CheckSequenceVerify). They both restrict when BTC can be spent, but they work in slightly different ways.
| Feature | CLTV (CheckLockTimeVerify) | CSV (CheckSequenceVerify) |
| --------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **How Time is Measured** |
Absolute. Targets a fixed point in the future.
Example: "The door opens at 9:00 AM on July 4th"
|
Relative. Measures time based on how long after a previous event.
Example: "The secondary door opens 48 hours after the primary door successfully opened"
|
| **Enforcement** | Prevents the transaction from being confirmed **until that exact time or block height has passed.** | Prevents the transaction from being confirmed until a specific **duration has passed since the previous one was confirmed.** |
| **Example Use Case** |
Lock BTC with a rule: “This BTC can only be spent after block 900,000.”
Before that block, any attempt to move it will be rejected.
|
Lock BTC with a rule: “This BTC can only be spent after 1,008 blocks (\~7 days) once the unbonding transaction is confirmed.”
The countdown begins once the unbonding is confirmed.
|
| **Functional Advantage** | Best for **fixed deadlines,** useful when you want a transaction to occur only after a specific block or time. | Best for **stringing together chains of transactions**, setting relative locks on unconfirmed or unbroadcast transactions, and ensuring they confirm in the expected order regardless of when they’re executed. |
| **Simple Analogy** | An absolute lock is like scheduling one email to send at 9:00 AM on July 4th. | A relative lock is like setting up an entire chain of emails where Email 2 sends 48 hours after Email 1 is opened, no matter when Email 1 was originally created. |
### **2. Staking Process Overview**
{% stepper %}
{% step %}
**User initiates lock**
A BTC holder creates a timelock transaction to lock BTC for a defined duration. During this time, the BTC is completely unspendable.
When creating the timelock transaction, metadata is embedded to:
* Indicates which validator/finalty provider you want to support
* Specifies a PoS chain-compatible address (e.g., EVM, CosmWasm, etc.) to receive rewards.
*Note on Integrations: Depending on the POS chain's design and types of timelocks, some integrations may require the user to construct additional transactions to define more complex logic, such as:*
* *Slashing conditions*
* *Early unbonding rules*
{% endstep %}
{% step %}
**Proof Registration**
Once your lock is confirmed on Bitcoin, a proof of lock is submitted to the PoS chain’s staking contract by a relayer or verifier. This registers the user’s BTC stake on the target chain.
{% endstep %}
{% step %}
**Reward Accrual**
Once registered, the user begins earning yield according to the network’s reward mechanism. Rewards are distributed to the address provided at the beginning of lock inititation.
{% endstep %}
{% step %}
**Unlock**
When the timelock expires, the BTC becomes spendable again on Bitcoin mainnet. To continue staking, a new timelock must be created.\
Note: *Some integrations allow early unbonding depending on the PoS chain’s specific design.*
{% endstep %}
{% endstepper %}
***
## **Integration**
Self-custodial BTC staking serves as a shared primitive across multiple networks. Each chain implements its own integration logic based on its consensus design and staking framework.

Slashing
Not applicable. No slashing risk for BTC stakers.
Yes, capped at 0.1% of the staked amount to deter malicious behavior.
Liquidity
BTC is locked until the timelock expires and only becomes spendable afterward.
Users can unbond early before the timelock ends, but must wait for a 1008-block delay (~7 days) before their BTC becomes spendable again.
Reward Multiplier
Boosted rewards apply when users dual-stake BTC and CORE.
If you only have BTC, you can match with CORE stakers on b14g’s Merge Marketplace and share boosted rewards.
Boosted rewards apply when users co-stake BTC and BABY.
If you only have BTC, you can match with BABY stakers on b14g’s Merge Marketplace and share boosted rewards.
b14g standardizes this process through a unified interface, letting BTC holders stake once and participate across multiple Bitcoin-aligned chains.

## **Benefits**
| Benefit | Description |
| --------------------------- | ------------------------------------------------------------------------- |
| **True Self-Custody** | Your BTC never leaves your wallet or the Bitcoin chain. |
| **Earn Real Yield** | Rewards come from real network security, not unsustainable yield farming. |
| **Cross-Chain Flexibility** | Same BTC lock can be used across different BTCFi networks. |
| **Transparent & Auditable** | All staking proofs and rewards visible on-chain. |
Self-Custodial BTC Staking is the core primitive of the **b14g BTCFi architecture**.
It connects Bitcoin’s native security with emerging L1 and L2 ecosystems — enabling BTC holders to earn yield while maintaining full control of their assets.
# Dual Staking
The infrastructure for sustainable BTCFi
**b14g Dual-Staking Layer** introduces a **modular dual-staking framework for Bitcoin**. It enables protocols to secure their networks by pairing their native tokens with BTC, addressing the long-standing challenges of [**token inflation** and **sell pressure** seen in existing BTC (re)staking models.](https://docs.b14g.xyz/architecture/pages/hV9f6tM7btf83TpRjD6y#id-2.-the-incentive-problem-why-early-btc-staking-fails)
Dual-staking is central to b14g’s mission to make Bitcoin **a productive, yield-bearing asset** while scaling the BTCFi ecosystem. It offers a **flexible, plug-and-play security layer** that any decentralized application can use to bootstrap or enhance economic security — all while keeping Bitcoin **fully self-custodial**.
***
## Key Participants
b14g Key Participants
* **Stakers** - Entities seeking to earn rewards by committing both Bitcoin and the protocol's native token. This group includes individual token holders, institutional investors, and liquid (re)staking protocols. Stakers lock their Bitcoin on the Bitcoin network and stake their native tokens on the EVM chain, contributing dual collateral to the network's security.
* **Actively Validated Service (AVS)** - Any decentralized system requiring economic security to operate reliably. This can include Layer 1 blockchains, Layer 2 scaling solutions, or other decentralized applications that benefit from stake-based security guarantees. For example, a lending protocol might use the b14g operator network to execute liquidations. Similarly, a new blockchain could utilize b14g operators as validators to secure its network. Each AVS defines the tasks required of operators and the associated reward and penalty mechanisms.
* **Operators** - They are individuals or organizations that run the specific tasks required by an AVS. In return for their services, operators receive rewards. However, they are also subject to penalties, or slashing, if they fail to perform their tasks correctly or act maliciously. The role of an operator varies depending on the AVS. For a lending AVS, operators would execute the liquidation of undercollateralized assets. For a blockchain AVS, operators would function as validators, confirming transactions and producing new blocks.
***
## Key Principles
#### **Built for Self-Custodial Security**
A key aspect is the focus on **trust** and **safety for BTC holders**. There is **no bridging, no wrapping, and no slashing of BTC**. BTC is time-locked self-custodially in the user's own wallet. Only the native token gets slashed in case of penalties. This self-custodial approach is crucial for unlocking broader participation from BTC holders who prioritize not risking their Bitcoin.
Users retain control of their BTC, even during staking.
#### **Modular and Flexible Infrastructure**
b14g provides a **Dual-Staking Module** that allows protocols to customize and integrate without building it from scratch. The solution allows for flexibility, including adjusting the BTC-to-token staking ratio, setting custom yield tiers, and aligning incentives with a protocol's specific goals.
Protocols gain full control over how their network is secured—and how that security model aligns with their tokenomics.
***
## Architecture
b14g connects **Stakers**, **Operators**, and **AVSs** through a modular infrastructure built around two core components: **Delegation Manager** and **Liquid Stake Manager.**
b14g Bitcoin dual-staking flow
The **Delegation Manager** is the coordination hub of b14g’s staking layer.
* **For stakers**: Delegation Manager verifies BTC lock proofs, accepts native token deposits, and delegates both to chosen operators. When stakers participate through the Delegation Manager, they agree to share in the rewards generated by their selected operator, and they also accept the risk of slashing if that operator fails to perform.
* **For operators**: It assigns stake and enforces slashing/reward conditions based on operator's performance.
* **For AVSs**: It connects them to a shared security layer, enabling them to outsource security to existing operators without needing to build their own infrastructure from scratch. The Delegation Manager also handles dual-staking logic, slashing enforcement, and reward distribution according to each AVS’s defined rules.
b14g Bitcoin liquid dual-staking flow
The **Liquid Stake Manager** introduces liquidity to staked and locked assets.
* **Staked protocol tokens** → Minted as **ERC-20 tokens**
* **Locked BTC** → Minted as **ERC-721 NFTs**
These tokens are freely transferable and tradable, offering users a liquid representation of their positions. The Liquid Stake Manager also helps optimize delegation across operators based on yield and slashing risk—maximizing returns for users who prefer a hands-off experience.
Rewards from dual-staking are distributed to the holders of these ERC tokens and NFTs.
***
The **b14g Dual-Staking Layer** transforms Bitcoin into an active, productive security asset — aligning BTC holders, protocol tokens, and decentralized services under one modular framework.

# Merge Marketplace
## What is Merge Marketplace?
The **Merge Marketplace** is a platform that connects stakers holding different types of assets, enabling them to participate in **Bitcoin dual-staking** collaboratively. By matching users who have complementary tokens, the Marketplace unlocks higher rewards and maximizes earning opportunities without requiring each individual to hold both assets.
***
## Why Merge Marketplace?
**Lower Capital Barriers:** Typically, dual staking often demands that participants hold two or more specific assets to access premium reward tiers. The Merge Marketplace eliminates this barrier by facilitating collaborations between stakers. Instead of buying additional tokens, BTC and token holders can pair with one another to meet the required ratio and unlock higher yields.
**Broaden Participation:** Since you don’t need to hold both assets yourself, the Merge Marketplace opens the door to higher yields for a broader range of participants. This collaboration not only maximizes individual earnings but also strengthens the protocol security by bringing more and more stakers.
***
## Merge Marketplace Architecture
**Key Components:**
* **Staker:** A user with one type of token (e.g., BTC) enters the Marketplace.
* **Merge Marketplace:** The platform matches this user with another staker who holds the complementary asset (e.g., CORE). The two stakers form a partnership that meets the asset requirements for **dual staking**.
* [**Dual Staking**](/architecture/dual-staking)**:** Once matched, their combined assets enter the dual staking process, unlocking higher reward tiers. The Merge Marketplace handles the logic to ensure both parties receive their fair share of rewards.
* **AVS (Actively Validated Service):** Actively Validated Services are new protocols or applications that bootstrap their security by leveraging staked BTC. Instead of starting from scratch and facing the “cold-start problem”—where emerging services often lack immediate security guarantees—AVS developers integrate with b14g’s dual staking to tap into the economic strength of Bitcoin. By having BTC locked into their security model, these services gain credibility and resilience from day one, ensuring trust, stability, and long-term sustainability as they grow.
***
## Integration
#### **Core Dual-Staking Integration**
In Core, higher yield tiers require staking BTC + CORE at a ratio of roughly 1:24,000.\
If you hold BTC but no CORE, the Merge Marketplace lets you find a CORE staker to merge with.\
Together, you meet the threshold for boosted rewards, earning more while reinforcing Core’s network security.

{% endcontent-ref %}
#### **Babylon Co-Staking Integration**
In Babylon, higher yield tiers require staking BTC + BABY at around 1:20,000.\
If you have BTC but no BABY, you can match with a BABY holder in the Marketplace.\
Both sides earn enhanced rewards, while collectively strengthening Babylon Genesis.

# Bittery
**Bittery** combines CoreDAO non-custodial BTC staking with an on-chain lottery mechanism — giving you the chance to win the full yield from the lottery while keeping your BTC safe and locked in your own wallet. All users keep full control of their BTC, and one lucky winner takes home all the rewards.
***
## Quick Overview
* **Stake BTC** on Bitcoin network with a minimum of 0.01 BTC.
* **BTC remains non-custodial** — your BTC is never moved, bridged, or wrapped. It stays time-locked in your own wallet.
* **Deposit Period**: You can join and deposit your BTC lock proof at any time before the current round ends. Deposit your BTC lock proof means assigning your BTC staking rewards to the Bittery prize pool.
* **Round Duration:** A new round starts every month, and each round ends with a single on-chain draw.
* **Prize pool:** Once the vault ends, all staking rewards accumulated during the vault’s duration are pooled — and **one winner is randomly selected on-chain** to receive the full yield.
* **Withdraw Period:** You can withdraw your BTC lock proof within the first 5 days of a round. After that, withdrawals reopen only after the draw is completed.
***
## How Bittery Works
#### Deposit & Enter
Lock your BTC non-custodially with a minimum of 0.01 BTC to help secure the Core chain and earn staking rewards. To enter Bittery, deposit your BTC lock proof into the vault.
{% hint style="success" %}
“Deposit” here only means assigning rewards to the round's prize pool. Your BTC stays locked on the Bitcoin network, in your own address.
{% endhint %}
Your odds of winning are based on how much reward your BTC lock generates relative to the total pool. More contribution = better odds.
You can leave the Bittery by withdrawing your BTC lock proof anytime within the first 5 days of a new round. After that, you can not leave and your BTC lock proof is locked to contribute rewards to prize pool until the round ends and a winner is drawn.
#### Wait for the Draw
All staking rewards from BTC locks during the round go into the Bittery prize pool. At the end of the round, one winner is randomly selected on-chain and gets 100% of the prize pool (minus fees).
Want to increase your chances next round? Just lock and deposit more BTC.
#### Claim & Withdraw
If you win, you can claim your prize immediately after the draw.
If your BTC is still under time-lock after the round ends, it will automatically roll over to the next round. You’ll have another 5-day window at the start of the next round to withdraw if you don’t want to continue.
***
## Bittery Rounds
Each Bittery round runs on a monthly schedule.
* Any BTC locks deposited during the round will have their rewards pooled together.
* Only rewards generated within the round’s timeframe count toward the prize.
* The winner is selected at the end of the round using on-chain randomization (Switchboard VRF).
* BTC locks can be added at any time before the current round ends.
***
## Prize Funding & Staking Rewards
All rewards come directly from the non-custodial BTC staking mechanisms. Bittery does not lend, wrap, or custody BTC. Users lock BTC directly on the Bitcoin network, and yield is generated by helping secure Core chain.
Each round's prize pool comes exclusively from rewards earned during that round duration, after deducting a vault fee.
Rewards generated after the round ends are either:
* Rolled into the next round, or
* Returned to you if you’ve withdrawn your BTC lock proof.
***
## **How to Win – Odds Calculation**
Your odds are based on how much reward you contribute to the pool.
For example, if your BTC lock earns 1,000 CORE in staking rewards during the round, and the total pool is 10,000 CORE, your odds of winning are **1 in 10**.
Only one winner is drawn per round.
***
## Risks – Important!
Your BTC stays non-custodial, time-locked in your own wallet. You control your keys at all times. You never transfer it to the Bittery contract. Bittery only handles reward assignment, prize draws, and prize distribution.
However, **if you do not win, you will not receive any rewards** — all yield goes to the winner.
Please assess your risk preference before participating.
***
## Fees
5% of each round’s prize pool is deducted as a vault fee. Fees are used to sustain vault operations and may be adjusted in future versions.

# Self-custodial BTC Staking (Core chain)
## Refresher on Core Chain and Core Dual-Staking
#### **Core Chain Overview:**
**Core** is a Bitcoin-aligned, EVM-compatible Layer 1 blockchain built to merge Bitcoin’s unmatched security with the programmability of smart contracts. Its unique **Satoshi Plus consensus** blends Bitcoin hash power, Bitcoin self-custodial staking and CORE staking to secure the network.
#### **Self-Custodial Bitcoin Staking:**
Core Self-Custodial Bitcoin Staking allows Bitcoin holders to lock BTC directly on the Bitcoin mainnet, secure Core chain and earn rewards in return — all while keeping full custody of their assets.
**Key characteristics:**
* **CLTV (CheckLockTimeVerify) Script:** BTC is locked for a specific duration. During this period, it cannot be moved until the time-lock expires.
* **No Slashing:** Your BTC is not exposed to slashing. Once the lock expires, you can always unlock and withdraw it.
* **Self-Custody:** You maintain control of your Bitcoin; Core chain simply verifies that your BTC lock is confirmed on Bitcoin network and eligible for securing the network and earn rewards.
This architecture ensures Bitcoin’s native security remains intact while making BTC a productive asset — without relying on bridges or custodians.
{% hint style="info" %}
*For foundational concepts, refer to* [*Self-Custodial BTC Staking.*](/architecture/self-custodial-bitcoin-staking)
{% endhint %}
#### **Dual Staking:**
To enhance yield potential, Core introduced **Dual Staking**, allowing users to stake both **BTC and CORE** to unlock higher reward tiers.
* Staking BTC alone earns a base yield.
* Adding CORE in proportion to BTC (e.g., 1:34,000) unlocks boosted yield tiers, 5-25x the base yield.
* Dual staking is optional but incentivized, as higher BTC:CORE ratios lead to higher reward multipliers.
***
## Building Dual Staking **Marketplace on Core Chain**
### **The Challenge**
While Dual Staking increases yield, it requires users to hold both BTC and CORE — a barrier for many Bitcoin holders. BTC users are often reluctant to purchase CORE due to **price volatility** or **portfolio concentration risks**.
This capital asymmetry means:
* BTC holders miss out on higher-yield opportunities.
* The base yield alone is not enough to attract sufficient BTC participation to secure the Core network.
* Lower BTC participation leads to weaker overall network security.
### **Solution: b14g Merge Marketplace**
The **b14g Merge Marketplace** solves this coordination problem by connecting BTC and CORE holders on-chain. It allows users to pair their assets without directly buying the other.
#### **b14g Advantage:**
* Preserve native self-custodial BTC staking. BTC remains time-locked in users' wallet on Bitcoin network, secured by CLTV time-locks.
* BTC holders can find CORE partners to reach higher yield tiers.
* CORE holders can match with verified BTC locks to earn dual-staking rewards.
* All interactions are automated, on-chain verifiable, and non-custodial.
***
## How BTC Staking works on b14g
#### **Key Components:**
| Component | Description |
| ------------------------- | -------------------------------------------------------------------------------------------------------------------------------------- |
| **CLTV Time-Lock Script** | Native Bitcoin locking mechanism ensuring self-custody. |
| **Relayer** | Monitor for valid BTC staking transactions, validate and register confirmed BTC staking position on Core chain. |
| **Core Staking Contract** | Records BTC staking delegation; Pays rewards as per Core concensus. |
| **Merge Marketplace** | Matching "orderbook" layer that connects BTC and CORE stakers for dual-staking. |
| **Order Contract** | Represents your staking position on the marketplace for dual-staking matching; Collects and splits yield between you and CORE stakers. |
#### **BTC Staking Flow**
1. **Order Creation:** Alice creates an **order** on the **b14g Merge Marketplace**, defining a reward-sharing ratio for future CORE staking partners and selecting the validators she wants to delegate to.
2. **BTC Lock:** Alice locks 10 BTC on the Bitcoin network for 90 days using a **CLTV time-lock script**.
3. **Proof Verification:** Once the lock transaction is confirmed on the Bitcoin network, **relayers** in Core’s infrastructure detect it and submit the proof to Core chain, making the BTC eligible for securing the network and earning rewards.
4. **Order Activation:** Alice’s BTC staking position is now registered on b14g Merge Marketplace as an **active order**, visible and open for CORE stakers to join.
5. **Dual-staking Matching:** Bob, looking to earn yield on his CORE tokens, matches with Alice’s order by staking his CORE. His CORE is sent directly to the **Core staking contract** — b14g never holds user funds.
6. **Reward Distribution:** **Order Contract** automatically collects rewards and routes them to:
1. Alice’s staked BTC generates rewards that go directly to her.
2. Bob’s staked CORE generates rewards that go directly to him.
3. Dual-staking boost rewards (from staking BTC + CORE) are shared between Alice and Bob according to the reward-sharing ratio defined in the order.
7. **Unlock:** After 90 days, Alice redeems her BTC. The whole process remains self-custodial.
***
## BTC Staking Strategy
Self-custodial BTC Staking on b14g combines:
* Core’s BTC Self-custodial Staking mechanism (using CLTV time-locks)
* Dual-staking matching mechanism via b14g Merge Marketplace, enabling BTC and CORE holders to collaborate for higher yield
There are two main strategies for dual-staking matching, each with a different balance between yield potential and convenience.
Merge Order Strategy
Fair Share Strategy
Dual-staking Matching
You lock your BTC and your staking position shows up as an open order on b14g Merge Marketplace.
CORE holders can match with your order to form a dual-staking pair.
Reward-sharing ratio is user-defined.
Same BTC lock & order mechanism, but with a hands-off approach.
System automatically matches your BTC with available CORE from the dualCORE vault.
Reward-sharing is defined by the system.
Your Yield
Yield depends on matching efficiency, reward sharing ratio, validator APR.
Choose this if you’re chasing the highest possible APR and don’t mind 0.05% APR if no CORE matches.
Pick this if you want a hands-off, consistent yield with automated dual-staking matching and reward compounding.
Key points to remember:
* Your **BTC remains fully self-custodial**, time-locked in your own wallet on the Bitcoin network, secured by CLTV time-locks.
* Only your **rewards** (in **CORE** or **dualCORE**) exist on Core chain, coordinated trustlessly between you and CORE stakers through the **Order Contract**.
***
## Source of Yield
> *If you don’t know the source of yield, you’re the yield.*
### How are yields generated?
Your yield comes from two sources:
* **BTC staking rewards (Base yield)**: Your BTC contributes to [Core Chain's Satoshi Plus Consensus](https://docs.coredao.org/docs/Learn/core-concepts/architecture), helping secure the Core chain and earning you yield in return.
* [**Dual-staking**](https://docs.coredao.org/docs/stake-and-delegate/dual-staking-working) **rewards (Boosts)**: Core Chain offers additional incentives when BTC and CORE are staked together. Through b14g Merge Marketplace, your BTC can be matched with CORE stakers to earn these extra rewards, boosting your APY without requiring you to hold CORE.
### What Affects Your APR (using Merge Order strategy)?
Your Merge Order APR depends on three factors:
1. **Reward split**
* You set the percentage of boosted rewards you keep vs. give the CORE staker. A bigger share for you reduces incentives for CORE stakers, which can slow match speed or reduce available yield.
* *Example:* A 60/40 split (60% to you) offers a high potential APR, but gives CORE stakers less incentive to match—so they may choose other orders with better splits. Without a CORE match at the optimal ratio, you’ll never hit that top-tier APR.
* **Tip:** A **50/50 split** often balances match speed and yield.
2. **Match ratio**
* The amount of CORE paired with your BTC determines your yield multipliers:\
Base Tier (no CORE matched) -> \~0.05% APR\
Tier 1 (4,250:1) → \~0.1% APR\
Tier 2 (12,750:1) → \~0.2% APR\
Tier 3 (34,000:1) → \~2% APR\
Partial matches earn at the tier corresponding to the actual ratio.\
These dual-staking ratio and yield multipliers are subject to change as per CoreDAO Governance.
* **Tip:** Break big stakes into smaller locks so they fill faster. Five orders of 10 BTC each need 290,000 CORE apiece to reach Tier 3, while one 50 BTC order needs 1,450,000 CORE—much harder to fill.
3. **Validator base APY**
* Each validator allocates a fixed total reward every epoch. When many users stake with the same validator, that reward pool is split among all delegators, so your individual slice shrinks.
* **Tip:** Break large stakes into smaller locks and spread them across different validators to keep your share of each reward pool larger. e.g., instead of staking 50BTC into 1 order -> 1 validator accordingly to this order, you could stake each 10 BTC one order, with different 10 validators.
{% hint style="info" %}
**Too much to manage?**
Try the **Fair-Share strategy** instead. It's the same BTC lock mechanism, but with a hands-off approach. Your BTC lock position still shows up as an open order on the Merge Marketplace, but the system auto-matches available CORE (from dualCORE vault) for you. If there’s enough CORE to reach the top tier, everyone earns it; if not, rewards are averaged so nobody drops to the 0.05% floor rate.
In short, you enjoy a steady APR without worrying about splits, tiers, or validator crowding.
Bonus: Rewards in **Fair-Share** strategy are **auto-compounding**, so your earnings grow on their own.

Self-custodial BTC staking on Core enables Bitcoin holders to earn real yield while preserving security and ownership. Integrated with **b14g’s Merge Marketplace**, it becomes more inclusive — lowering entry barriers and connecting BTC and CORE holders for sustainable, dual-asset yield.
> b14g transforms Bitcoin into productive capital on Core — fully self-custodial, collaborative, and yield-optimized.
**Enjoy your BTC yield!**
# Merge Order Strategy
**Merge Order** strategy lets you lock your BTC **self-custodially** on Bitcoin network to secure Core Chain and earn yields. Rewards paid in claimable CORE token daily.
**You stay self-custodial.** Your BTC is locked from your own wallet, and only your keys can unlock it later.
***
## Why Use Merge Order?
Core Chain rewards dual-stakers (holding both BTC + CORE) at higher rates—up to \~5% APY. If you only have BTC, yields drop significantly to below 0.05%.
Merge Order is the fix. It lets you team up with other CORE stakers, forming a dual-staking position so both of you get boosted yield without buying the other asset.
***
## Quick Overview
| **Deposit asset** | Native BTC (timelocked in your own wallet) |
| ----------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Min. deposit** | 0.01 BTC (as per Core's official UI) |
| **Lock options** | Based on your preference |
| **Unlock rule** | Unlock only after your chosen period |
| **APR** |
|
| **Reward token** | CORE (paid daily) |
***
## How Merge Order Works
1. **Lock Your BTC**\
Sign a Bitcoin timelock transaction for your chosen duration. Your BTC stays in your own wallet—self-custodial and secure.
2. **Set Terms**
* Choose how to divide boosted rewards between you and the eventual CORE match (e.g., 50%/50%).
* Select a Core Chain validator to receive the combined stake.
* Once the lock transaction is confirmed on the Bitcoin network, relayers in Core chain detect it and submit the proof to the Core blockchain so your BTC can help secure Core Chain and earn you yield in return.
3. **Wait for CORE Match**
* Your BTC lock position appears as an open order on b14g Merge Marketplace.
* A CORE holder accepts your terms and pairs their CORE with your BTC. Together, you form a dual-staking pair.
4. **Start Earning**\
The pair earns boosted APR. Rewards are paid daily in claimable CORE.
5. **Unlock BTC**\
When your timelock ends, you broadcast a normal Bitcoin spend back to yourself.
***
## What Affects Your APR?
Your Merge Order APR depends on three factors:
1. **Reward split**
* You set the percentage of boosted rewards you keep vs. give the CORE staker. A bigger share for you reduces incentives for CORE stakers, which can slow match speed or reduce available yield.
* *Example:* A 60/40 split (60% to you) offers a high potential APR, but gives CORE stakers less incentive to match—so they may choose other orders with better splits. Without a CORE match at the optimal ratio, you’ll never hit that top-tier APR.
* **Tip:** A **50/50 split** often balances match speed and yield.
2. **Match ratio**
* The amount of CORE paired with your BTC determines your yield tier:\
Tier 1 (3,625:1) → \~0.1% APR\
Tier 2 (10,875:1) → \~0.2% APR\
Tier 3 (29,000:1) → \~2% APR\
Partial matches earn at the tier corresponding to the actual ratio.
* **Tip:** Break big stakes into smaller locks so they fill faster. Ten orders of 5 BTC each need 145,000 CORE apiece to reach Tier 3, while one 50 BTC order needs 1,450,000 CORE—much harder to fill.
3. **Validator base APY**
* Each validator allocates a fixed total reward every epoch. When many users stake with the same validator, that reward pool is split among all delegators, so your individual slice shrinks.
* **Tip:** Break large stakes into smaller locks and spread them across different validators to keep your share of each reward pool larger.

# Fair-Share Strategy
**Fair‑Share** Strategy is a **self‑custodial** Bitcoin staking "pool" on the b14g platform. It lets you lock BTC on the Bitcoin network, secure **Core Chain**, and earn yield that auto‑compounds via the **dualCORE** reward token.
**You keep full control of the BTC.** It never leaves your wallet or Bitcoin network.
***
## Quick Overview
| **Deposit asset** | Native BTC (time‑locked in your own wallet) |
| ----------------- | ------------------------------------------- |
| **Min. deposit** | 0.01 BTC (as per Core's official UI) |
| **Lock options** | Based on your preference |
| **Unlock rule** | Unlock only after your chosen period |
| **APR** | Same rate for all users |
| **Reward token** | dualCORE (compounds automatically) |
***
## How are yields generated?
#### Base staking yield (securing Core Chain)
The strategy lets you time-lock your BTC in your own Bitcoin wallet—no bridge, no custodian. Once the lock is confirmed on the Bitcoin network, relayers in Core chain detect it and submit the proof to Core blockchain so your BTC can help secure Core network and earn you yield in return.
#### Boosted yield (dual-staking bonus)
Core Chain (an EVM network) pays extra interest when a stake combines **BTC + CORE** (native token of Core chain) in a set ratio (e.g., 1 BTC : 29 000 CORE). That combo is called **dual‑staking**.
Most people don’t hold both coins in the perfect mix, so b14g created two options:
| Strategy | How It Matches CORE | Your Yield | Reward Token |
| --------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------- |
| **Merge Order** | You lock your BTC and it shows up as an open order on [b14g Merge Marketplace](/products/for-core-holders/core-marketplace). CORE holders can match with your order to form a dual-staking pair. |
Yield increases with more matched CORE.
Varies: ≈ 2% if fully matched (1 BTC : 29 000 CORE), down to 0.05% floor rate if no match.
| Claimable **CORE** daily |
| **Fair-Share** | Same BTC lock mechanism, but with a hands-off approach. System auto-matches CORE for you. |
Same rate for everyone.
If there’s enough CORE to reach the top tier, everyone earns it; if not, rewards are averaged so nobody drops to the 0.1 % floor rate.
| Auto-compounding [**dualCORE**](/products/for-core-holders/dualcore-liquid-staking) daily |
Key points to remember:
* Your BTC stays **self-custodial** (timelocked in your own wallet).
* Only the rewards (CORE or dualCORE) live on Core’s EVM chain; your principal stays on Bitcoin network.
***
## How Fair-Share Works
1. **Lock BTC**\
You sign one Bitcoin transaction that locks your coins for a period you want. Your BTC stays in your own wallet, self-custodial and secure.\
Once the lock transaction is confirmed on the Bitcoin network, relayers in Core chain detect it and submit the proof to the Core blockchain so your BTC can help secure Core Chain and earn you yield in return.
2. **System pairs BTC with CORE**\
The system adds CORE from b14g’s [dualCORE vault](/products/for-core-holders/dualcore-liquid-staking), so the BTC meets Core Chain’s dual‑staking requirements, earning boosted yields. The combined stake is spread across high‑yield Core validators.
3. **Auto‑compound**\
CORE rewards are converted to **dualCORE** and paid out daily. Holding dualCORE automatically re‑invests those rewards.
4. **Unlock BTC**\
When your timelock ends, you broadcast a normal Bitcoin spend back to yourself. You keep all earned dualCORE.

# Self-custodial BTC Staking (Babylon)
## Refresher on Babylon Genesis and Co-Staking
#### **Babylon Genesis Overview**
[Babylon](https://babylonlabs.io/) is a Bitcoin-secured proof-of-stake (PoS) chain designed to extend Bitcoin’s security to other ecosystems without requiring wrapped assets or custodial bridges. It introduces a novel “Bitcoin Timestamping” and “Finality Provider” model, enabling Bitcoin to serve as the ultimate source of trust for other blockchains.
#### **Self-Custodial Bitcoin Staking**
Babylon Self-Custodial Bitcoin Staking lets Bitcoin holders stake their BTC **directly on the Bitcoin network,** no wrapping, no bridging, and no third-party custody.
When you stake, your BTC stays in your own wallet and is **time-locked** using Bitcoin’s built-in script.\
You delegate your staked BTC to a Finality Provider, who helps secure Proof-of-Stake (PoS) chains. In return, you earn rewards.
**Key characteristics:**
* **CSV (CheckSequenceVerify) Script:** Your BTC is locked with a **time delay** on the Bitcoin network. You can only spend it again once the lock period ends.
* **Slashing (capped):** Protocol slashing **can apply** for defined misbehavior conditions (e.g., security/consensus faults), but is **capped at 0.1%** of the staked BTC.
* **Self-Custody:** You always keep control of your BTC. Babylon only verifies the proof of your lock on Bitcoin to confirm eligibility for securing networks and earning rewards.
This design keeps Bitcoin’s native security intact while allowing BTC to become a productive, yield-generating asset — all without bridges or custodians.
{% hint style="info" %}
*For foundational concepts, refer to* [*Self-Custodial BTC Staking.*](/architecture/self-custodial-bitcoin-staking)
{% endhint %}
#### **Co Staking**
In 2025, Babylon introduced **Co-Staking**, a mechanism designed to align incentives between BTC stakers and BABY token holders.
* Staking BTC alone earns a base yield.
* Adding BABY in proportion to BTC (e.g., 1 BTC : 20,000 BABY) unlocks co-staking boosted rewards, \~5-10x the base yield.
* Co-staking is optional but incentivized, as higher BTC:BABY ratios lead to higher reward.
Example:
\
• Alice stakes 6 BTC + 50K BABY → weight 2.5
\
• Bob stakes 6 BTC + 150K BABY → weight 6
If 10K BABY rewards are distributed →
Alice earns 2.94K, Bob earns 7.06K.
***
## Building Dual Staking **Marketplace on Babylon**
### **The Challenge**
While Co Staking increases yield, it requires users to hold both BTC and BABY — a barrier for many Bitcoin holders. BTC users are often reluctant to purchase BABY due to **price volatility** or **portfolio concentration risks**.
This capital asymmetry means:
* BTC holders miss out on higher-yield opportunities.
* The base yield alone is not enough to attract sufficient BTC participation to secure the Babylon and its BSNs.
* Lower BTC participation leads to weaker overall network security.
### **Solution: b14g Merge Marketplace**
The **b14g Merge Marketplace** solves this coordination problem by connecting BTC and BABY holders on-chain. It allows users to pair their assets without directly buying the other.
#### **b14g Advantage:**
* Preserve native self-custodial BTC staking. BTC remains time-locked in users' wallet on Bitcoin network, secured by CSV time-locks.
* BTC holders can find BABY partners to reach higher yield tiers.
* BABY holders can match with verified BTC locks to earn co-staking rewards.
* All interactions are automated, on-chain verifiable, and non-custodial.

## How BTC Staking works on b14g
#### **Key Components:**
| Component | Description |
| --------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------- |
| **CSV Time-Lock Script** | Native Bitcoin locking mechanism ensuring self-custody. |
| **Vigilante** | Monitor for valid BTC staking transactions, validate and register confirmed BTC staking position on Babylon chain. |
| **Babylon Staking Modules** | Records BTC staking delegation; Pays rewards as per Babylon reward policy. |
| **Merge Marketplace** | Matching "orderbook" layer that connects BTC and BABY stakers for co-staking. |
| **Order Contract** | Represents your BTC staking position on the marketplace for co-staking matching; Collects and splits yield between you and BABY stakers. |
#### **BTC Staking Flow**
1. **Order Creation:** Alice creates an **order** on the **b14g Merge Marketplace**, defining a reward-sharing ratio for future BABY staking partners and selecting the FP she wants to delegate to.
2. **BTC Lock:** Alice locks 10 BTC on the Bitcoin network using a **CSV time-lock script**.
3. **Proof Verification:** Once the lock transaction is confirmed on the Bitcoin network, **Vigilante** in Babylon's infrastructure detect it and submit the proof to Babylon chain, making the BTC eligible for securing networks and earning rewards.
4. **Order Activation:** Alice’s BTC staking position is now registered on b14g Merge Marketplace as an **active order**, visible and open for BABY stakers to join.
5. **Co-staking Matching:** Bob, looking to earn yield on his BABY tokens, matches with Alice’s order by staking his BABY. His BABY is sent directly to the **Babylon staking module** — b14g never holds user funds.
6. **Reward Distribution:** **Order Contract** automatically collects rewards and routes them to:
1. Alice’s staked BTC generates rewards that go directly to her.
2. Bob’s staked BABY generates rewards that go directly to him.
3. Co-staking boost rewards (from staking BTC + BABY) are shared between Alice and Bob according to the reward-sharing ratio defined in the order.
7. **Unlock:** After the lock period ends, Alice can redeem her BTC. If she chooses to **unbond early** before the time-lock expires, she can do so, but must wait for a **301-block (\~3 days)** unbonding period before her BTC becomes spendable again. The entire process remains fully self-custodial.
{% hint style="info" %}
Key points to remember:
* Your **BTC stays self-custodial**, time-locked in your own wallet on the Bitcoin network.
* Only rewards are on Babylon Genesis; matching and splits are handled by contracts.
* **Slashing exists** on Babylon, with a **maximum penalty of 0.1%** of the staked BTC.
{% endhint %}

## Source of Yield
> *If you don’t know the source of yield, you’re the yield.*
### How are yields generated?
Your yield comes from two sources:
* **BTC staking rewards (Base yield)**: Your BTC contributes to [Babylon network security](https://docs.babylonlabs.io/guides/overview/babylon_genesis/#consensus--security-model), earning you yield in return.
* [**Co-staking**](https://forum.babylon.foundation/t/inflation-reduction-and-the-introduction-of-co-staking/718/) **rewards (Boosts)**: Babylon offers additional incentives when BTC and BABY are staked together. Through b14g Merge Marketplace, your BTC can be matched with BABY stakers to earn these extra rewards, boosting your APY without requiring you to hold BABY.

# BTCFi Lending Vault
b14g introduces BTCFi Lending Vaults, a suite of yield-generating products designed to empower Bitcoin holders to earn consistent returns on their various Bitcoin-based assets. Built upon a robust and innovative DeFi infrastructure, our vaults simplify the process of yield generation, offering user-friendly interactions coupled with secure and efficient asset management. BTCFi Lending Vaults embody b14g's core mission: to make Bitcoin DeFi accessible, safe, and truly rewarding for everyone.
***
## Quick Overview
BTCFi Lending Vaults empower Bitcoin holders to effortlessly earn yield on their Bitcoin-based assets. Key features include:
* Accepts deposits of various Bitcoin-based assets (e.g., WBTC, solvBTC.core, lstBTC, USDT,...)
* Generates yield denominated in the deposited asset, compoundingly
* Withdraw anytime with 1-day unbonding, no lock-ups
* Yield generated through lending and strategic reinvestment into the b14g Merge Marketplace
***
## How It Works
BTCFi Lending Vaults securely and automatically generate yield through a straightforward process:
**1. Deposit:** Users deposit their chosen Bitcoin-based asset (e.g., WBTC, solvBTC.core, lstBTC) directly into the respective BTCFi Lending Vault.
**2. Yield Generation:**
* The vault supplies the deposited asset to lending platforms (e.g., Colend), earning interest rewards denominated in the deposited Bitcoin-based asset.
* Additionally, the vault borrows CORE tokens against the deposited asset as collateral and strategically reinvests these CORE tokens within the b14g ecosystem, such as staking in the Merge Marketplace, generating further rewards in CORE. CORE rewards are converted back into the deposited asset. Vaults auto-compound rewards by supplying converted rewards back into lending platforms.
**3. Withdrawal:** Users can easily withdraw their original deposited asset and the accumulated rewards at any time, subject to a brief 1-day unbonding period. No lock-ups.
***
## Yield Sources
The BTCFi Lending Vaults generate yield from multiple sources of yield:
#### Base Yield
* Generated from lending the deposited Bitcoin-based asset (e.g., WBTC, solvBTC.core, lstBTC) through integrated lending protocols (e.g., Colend), with yield denominated in the deposited asset.
* CORE tokens borrowed against deposited Bitcoin-based asset are invested into the b14g marketplace, generating yield in CORE token. CORE rewards are auto-converted back into the deposited asset.
#### Additional Incentives
* Additional b14g points for vault participants
***
## Risks and Mitigation
{% hint style="info" %}
**Privileged Roles and Security**
The vault employs a multi-layered security model:
* **Distributed Control**: The vault will be a shared multi-sig Safe. A majority of signers is required to make any changes to the strategy, such as accepting new assets or whitelisting new markets.
* **Transparent Operations**: The on-chain strategies can be monitored to verify execution and prevent misuse of funds.
* **Strategy Constraints**: The vault is limited to a pre-defined mandate that defines its deployment and risk management parameters.
{% endhint %}
Participating in the BTCFi Lending Vaults, like all DeFi activities, involves certain risks you should know about. At b14g, we want to be upfront about that — and we have also proactively implemented several measures to mitigate these potential issues and ensure the security and efficiency of the vault.
**Smart Contract Risks**
The vault operates through smart contracts, including those tied to Colend and the b14g marketplace. Like any code, these could contain bugs or vulnerabilities that might lead to fund loss. To reduce this risk, we have undergo thorough audits by reputable third-party security firms before deployment. These audits will scrutinize the code for potential weaknesses and ensure adherence to best security practices. [\[Audit reports available here\]](/audits)
**Integration Risk**
Since the yield we accumulate comes from our integrated protocols, the risks associated with them is also something we have to account for. If one of those protocols is exploited or has a critical design flaw, it could affect our vault too.
To mitigate this:
* We only integrate with protocols that have strong reputations and proven security.
* We’ve built a real-time risk engine that continuously monitors all integrated protocols.
* Vault interactions are governed by a multi-signature system, adding a safeguard against single points of failure or unauthorized changes.
Our Current integration partners are
* Colend
**Liquidation Risks** (related to borrowing CORE)
The vault borrows CORE tokens against the deposited Bitcoin-based asset. A significant and rapid decrease in the price of the collateral asset (e.g., WBTC, solvBTC.core, lstBTC) could lead to the vault's collateral falling below the required threshold, potentially triggering liquidation of the borrowed CORE position and potentially impacting the overall yield.
To mitigate this:
* We maintain conservative collateral ratios with **a health factor threshold of 1.5.**
* The vault constantly tracks collateral levels and will automatically rebalance or reduce borrowing if the health factor approaches that threshold.
Risk is part of DeFi—but so is smart risk management. The BTCFi Lending Vaults are designed with guardrails and proactive monitoring to keep it resilient in volatile conditions.

# Core Marketplace
https\://app.b14g.xyz/marketplace
## Refresher on Core Chain and Core Dual-Staking
**Core Chain Overview:**\
[Core](https://coredao.org) is the first Bitcoin-aligned, EVM-compatible Layer-1 blockchain designed to combine Bitcoin’s security with smart contract flexibility. By anchoring its consensus to Bitcoin mining hash power (≈75%) and leveraging Self-Custodial Bitcoin Staking, Core enables BTC holders to earn yield while securing the network, without ever giving up control of their Bitcoin.
**Self-Custodial Bitcoin Staking:**\
Introduced in April 2024, [Self-Custodial Bitcoin Staking](https://docs.coredao.org/docs/Learn/products/btc-staking/overview) on Core allows users to stake their BTC without relinquishing control of their assets. By doing so, they earn CORE token rewards natively on the Core chain. This approach eliminates additional trust assumptions, making Bitcoin staking more secure, transparent, and accessible.
**Dual Staking:**\
To enhance yield potential, Core introduced **Dual Staking**, allowing users to stake both **BTC and CORE** to unlock higher reward tiers.
* Staking BTC alone earns a base yield.
* Adding CORE in proportion to BTC (e.g., 1:34,000) unlocks boosted yield tiers, 5-25x the base yield.
* Dual staking is optional but incentivized, as higher BTC:CORE ratios lead to higher reward multipliers.
## How b14g Merge Marketplace Expands Core Dual-Staking
#### **The Challenge:**
While Dual Staking offers higher yields, it can be capital-intensive.
To unlock the highest yield tiers, users must hold both BTC and CORE in the required ratio (e.g., 1:34,000). However, many users may only have one asset or lack the capital to meet this ratio, limiting their access to these top-tier yields.
#### **The b14g Merge Marketplace Solution:**
The **b14g Merge Marketplace** solves this by turning **dual staking into collaboration**. It connects BTC holders and CORE holders, allowing them to **dual-stake together** and unlock boosted rewards **without needing to buy the missing asset.**
* **For BTC Holders:**\
If you have BTC but no CORE, you can create an order on the Merge Marketplace. A CORE holder can then match with you — together, you qualify for higher-tier yields without additional capital.
* **For CORE Holders:**\
If you have CORE but not enough BTC, you can browse existing BTC staking orders and match with one. Your contribution helps reach the ideal BTC:CORE ratio, and both parties earn a share of boosted rewards.
#### **Why It Matters**
By matching stakers across assets, the **Merge Marketplace**:
* **Reduces capital barriers:** you no longer need to hold both assets.
* **Expands participation:** more BTC and CORE holders can earn dual-staking yield.
* **Strengthens security:** higher total staked assets = stronger consensus base.
## How Merge Marketplace works
b14g Merge Marketplace is a set of core smart contracts deployed on Core network. It integrates BTC staking and CORE staking to maximize rewards for both stakers.
1. **BTC Staking:** Alice creates a merge order on the b14g Merge Marketplace. Alice then stakes her native BTC on Bitcoin network through Core's Non-custodial BTC staking mechanism.
2. **CORE Staking:** Bob, looking to earn yield on his CORE tokens, matches with Alice’s order by staking his CORE. His CORE is sent directly to the Core staking contract — b14g never holds user funds. Check this [transaction example](/products/for-core-holders/core-marketplace/transaction-example-stake-core) for more info.
3. **Reward Distribution:** Here’s how rewards are generated and sent back to users:
1. Alice’s staked BTC generates rewards that go directly to her.
2. Bob’s staked CORE generates rewards that go directly to him.
3. Dual-staking boost rewards (from staking BTC + CORE): The boosted dual-staking rewards (from combined BTC + CORE) are automatically split between them.
**Key Points**
* BTC stays timelocked in users' wallet on Bitcoin network, no custody risk.
* All actions (orders, matches, rewards) happens on Core network.
* b14g contracts only coordinate dual-staking, never hold user funds.
* Transparent and verifiable, anyone can audit activity on-chain.

## **In Summary:**
* **Core Chain** provides a secure, Bitcoin-aligned foundation for smart contract-enabled DeFi.
* **Dual Staking on Core** allows users to achieve higher BTC staking yields by adding CORE to their positions, incentivizing deeper ecosystem engagement.
* **b14g Merge Marketplace** removes the capital barrier and complexity by connecting stakers who lack one asset with those who have it, expanding participation and helping Core achieve healthier BTC:CORE ratios. The architecture integrates seamlessly with existing Core contracts, relying on its robust infrastructure for security and yield distribution.
With b14g’s Merge Marketplace, everyone can access and maximize the benefits of Dual Staking on Core—creating a more vibrant, user-friendly, and growth-oriented DeFi landscape.
# Transaction Example: Stake CORE
Here a CORE staking tx example on b14g Merge Marketplace:
* If you check a staking tx under the **Overview** tab, you’ll see CORE moving from the user’s wallet to the marketplace contract.
* If you check the **Internal Txns** tab, you’ll see the full flow of the staking tx:
CORE moves from the user’s wallet → marketplace contract → selected order contract → and finally, to the **Core staking contract.**
{% hint style="info" %}
This flow is automatic in a single staking transaction. It operates independently as coded, immune to interference. No funds are stored on our smart contract; they are stored in the Core staking contract.
{% endhint %}
* If you check the **Logs** tab, you’ll see which validator the order delegated CORE to.
# dualCORE - Liquid Staking
https\://app.b14g.xyz/vaults/core
dualCORE is b14g’s liquid dual‑staking token. It lets you keep earning Core staking rewards and dual‑staking boost while your tokens remain liquid to use across DeFi.
***
## Quick Overview
The **dualCORE Vault** keeps your CORE liquid while boosting your rewards—automatically.
* Deposit CORE, receive dualCORE
* Target APY: 20%+ (variable)
* Yield generated through [staking CORE into b14g Merge Marketplace](#wow-20--apy-is-high-how-does-dualcore-offer-such-high-yields), matching with BTC, unlocking dual-staking boosted yield.
* Yield is [auto-compounded](#how-to-track-how-much-i-earned-through-dualcore-vault) directly in your wallet. No need to claim or restake manually.
* Withdraw anytime with 1-day unbonding (0% fee) or instant withdrawal (10 % fee).
***
## **What is liquid dual-staking?**
Staking CORE helps secure Core network, earn staking rewards, but the trade-off is staked CORE tokens are locked and become illiquid. This means you can’t transfer, sell, or use your CORE tokens in DeFi while they’re staked.
**Liquid dual‑staking** **dualCORE** fixes that.
* **Deposit CORE → Receive dualCORE**, an ERC20 liquid dual-staking token.
* dualCORE represents your staked CORE **plus** all the rewards it earns.
* You can **transfer, trade, or use dualCORE in DeFi** while the vault keeps accruing staking and dual‑staking rewards for you.
***
## How Is It Different From stCORE?
You might ask: *“Isn’t this just like stCORE?”*
Not quite. Here’s what sets **dualCORE** apart:
| | stCORE | dualCORE |
| ------------------------- | ------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------ |
| **Token Type** | Liquid staking token | Liquid staking token |
| **Yield Sources** | CORE staking rate only |
CORE staking rate
Dual-staking boost
|
| **APY (as of this post)** | \~8% | \~20%+ |
| **Redemption time** | 7 days (you miss out on staking rewards during that long redemption time) |
Normal mode: 1 day, no fee.
Instant mode: No wait time, 10% fee.
|
| **Extra DeFi yield** | Limited | Works as yield aggregator (TBD) |
***
## Wow, 20%+ APY is high! How does dualCORE offer such high yields?
**dualCORE** taps into **Core’s dual-staking system**, which offers enhanced rewards when both BTC and CORE are staked together.
Here’s what happens under the hood:
* You deposit CORE into the dualCORE vault.
* The vault stakes that CORE into active BTC orders on [**b14g Merge Marketplace**](/products/for-core-holders/core-marketplace)**,** forming a dual-staking position.
* You earn boosted yields from dual-staking even though you only supplied CORE.
* Your rewards are auto-compounded daily.
All of this happens **automatically**.
{% hint style="info" %}
*b14g Merge Marketplace connects BTC stakers with CORE stakers to collaboratively dual-stake.* *BTC stakers create orders and stake BTC non-custodially, then CORE holders stake CORE into these orders to unlock dual-staking boost rewards for both.* *This means you can stake either BTC or CORE alone and still earn dual-staking boost rewards. It’s live at* [*https://app.b14g.xyz/*](https://app.b14g.xyz/)*.*
{% endhint %}
***
## **So, w**hy using dualCORE Vault instead of staking CORE directly on the Merge Marketplace?
Manually staking on the Merge Marketplace requires effort:
* You need to browse active orders to find the best APR. You also have to constantly monitor and manually reallocate when new orders with better rates appear.
* You must track expired orders and move your funds to new ones.
* You need to claim and reinvest rewards daily to maximize returns.
Honestly, it’s **time-consuming** and can feel overwhelming, especially for beginners (or for those of us who prefer a simpler life 🤷♀️).
**dualCORE Vault fixes that.**
All you need to do is deposit your CORE into the vault. It’ll take care of everything:
* Allocating your CORE to the orders with highest APR.
* Reallocate your CORE when orders expired.
* Automatically claiming and reinvesting rewards to compound your returns.
It’s DeFi made simple—so you can sit back, relax, and still earn more.
***
## How to track how much I earned through dualCORE Vault?
dualCORE is a derivative token, where your yield is auto-compounded directly in your wallet. No need to claim or restake manually. While your dualCORE balance may stay the same, its value against CORE increases over time as rewards are applied in the background.
For example, 1 dualCORE today might be worth 1.1 CORE. But after a few days of staking, that same 1 dualCORE could be worth 1.2 CORE. When you choose to unstake, you'll receive more CORE than you initially put in, reflecting the rewards you've accumulated.

# Technical Design (dualCORE)
## Design Summary[](https://docs.coredao.org/docs/Learn/products/stCore/design#design-summary)
* We introduce the dualCORE Vault along with its standard ERC-20 token, dualCORE.
* Users interact with the vault to mint, redeem (normal/instant mode), and withdraw their assets.
* The vault applies yield strategies within the b14g Merge Marketplace, which directly interacts with the Core Staking Contract to earn dual-staking yields.
* All value accrued within the vault is reflected in the dualCORE token’s value.
* The CORE/dualCORE conversion ratio is auto-updated daily, aligning with Core staking’s turn-round mechanism.
* To optimize yield strategies, system operators have additional methods to rebalance and adjust vault allocations.
## **User Perspective**
**Deposit & Mint**
* Users deposit **CORE** into the **dualCORE Vault**, which mints **dualCORE tokens** (ERC-20) based on the current dualCORE/CORE exchange rate and sends dualCORE tokens to the user's wallet.
* Throughout the day (UTC), users can mint dualCORE at the same conversion ratio. Example: If the conversion ratio is 1:1.2, depositing 120 CORE will mint 100 dualCORE.
**Redeem**
Users can always redeem their dualCORE tokens for CORE at the current exchange rate. Example: If the current conversion ratio is 1:1.2, redeeming 100 dualCORE will return 120 CORE.
There are 2 redemption modes:
* Normal Redemption: Once users request normal redemption from the system, it takes 1 day for them to withdraw CORE tokens to their wallet (no redemption fee).
* Instant Redemption: Instant redemption lets users withdraw CORE immediately to their wallet without any redemption period (with a 10% fee).
**Common ERC-20 Use Cases**
Since dualCORE is a standard ERC-20 token, it can be transferred, used in DeFi protocols, provided as liquidity on DEXs, swapped, and more.
## Implementations[](https://docs.coredao.org/docs/Learn/products/stCore/design#implementations)
User Methods in dualCORE Vault
* **stake()** → Deposit CORE and mint dualCORE.
* **unbond()** → Request redemption from dualCORE to CORE (normal redemption).
* **withdraw()** → Withdraw CORE to wallet once the normal redemption period ends.
* **withdrawDirect()** → Withdraw CORE immediately to wallet with no redemption period applied (instant redemption).
Operator Methods in dualCORE Vault
* **ReInvest()** → Periodically reinvests CORE into orders on [**Merge Marketplace**](/products/for-core-holders/core-marketplace) to maximize Core dual-staking yield and auto-compound rewards. The system reallocates funds by topping up the highest-yielding orders and withdrawing from the lowest-yielding invested ones.
### **dualCORE/CORE Conversion Ratio Calculation**[](https://docs.coredao.org/docs/Learn/products/stCore/design#stcorecore-conversion-ratio-calculation)
After each turn round in Core staking mechanism, the vault collects rewards from Merge Marketplace orders and stakes them back to compound returns. During this process, the vault moves CORE from lower-yielding orders to higher-yielding ones to maximize vault overall APY.
And after that the conversion ratio of dualCORE/CORE can also be updated. The formula for that is:
{% code overflow="wrap" %}
```
Total Amount of CORE in the vault / dualCORE.totalsupply()
```
{% endcode %}
Since Core staking rewards are only distributed once per day, the conversion rate remains unchanged throughout the day until the next turn round.
### **Deposit/Redeem Restrictions & Dues Protection**
The Core staking contract enforces these rules:
* When delegating CORE, the amount must be >= 1 CORE.
* When undelegating CORE:
* The amount must be >= 1 CORE, and
* The remaining CORE left on a validator of this address must be >= 1 or =0.
Since these restrictions also apply to Merge Marketplace, and the Vault applies yield strategies within the Merge Marketplace, it must adhere to the same rules when executing **stake()**, **unbond()**, and **withdrawDirect()** operations.
### ABI
{% code overflow="wrap" %}
```json
// abi for reading conversion rate from contract
[{
"inputs": [
{
"internalType": "uint256",
"name": "_dualCore",
"type": "uint256"
}
],
"name": "exchangeCore",
"outputs": [
{
"internalType": "uint256",
"name": "",
"type": "uint256"
}
],
"stateMutability": "nonpayable",
"type": "function"
}]
```
{% endcode %}
The function calculates the amount of CORE received when a given amount of dualCORE is provided. For example, if the input parameter is 1 dualCORE (1e18), the corresponding output is 1.039864488620697759 CORE (1039864488620697759).
dualCORE Vault contract address: [0xee21ab613d30330823D35Cf91A84cE964808B83F](https://scan.coredao.org/address/0xee21ab613d30330823D35Cf91A84cE964808B83F)
```json
// abi for Deposit (stake())
[
{
"inputs": [],
"name": "stake",
"outputs": [],
"stateMutability": "payable",
"type": "function"
}
]
```
When a user deposits CORE to mint dualCORE, they simply call the `stake()` function and send the desired amount of CORE as `msg.value`. Based on the current CORE/dualCORE exchange rate, the vault will mint the corresponding amount of dualCORE.
For example, in this transaction [here](https://scan.coredao.org/tx/0x1032960d368d9cccb9fe22d49d552230e10775567ff6937bbd2c444d32624458), the user sent 3 CORE to the contract via `msg.value`, and the contract minted 3 dualCORE in return.
{% code overflow="wrap" %}
```json
// abi for Normal Redemption (unbond() and Withdraw()) and Immediate Redemption (withdrawDirect())
[
{
"inputs": [
{

"type": "bool"
}
],
"name": "withdrawDirect",
"outputs": [],
"stateMutability": "payable",
"type": "function"
}
]
```
{% endcode %}
\- Normal Redemption: Call unbond(amount of dualCORE to withdraw, true). After a 1-day delay, call withdraw() to complete the process.
\- Immediate Redemption: Call withdrawDirect(amount of dualCORE to withdraw, true) for instant withdrawal.

## Refresher on Babylon and Babylon Co-Staking
#### **Babylon Genesis Chain Overview:**
Babylon is a Bitcoin-secured proof-of-stake (PoS) chain designed to extend Bitcoin’s security to other ecosystems without requiring wrapped assets or custodial bridges. It introduces a novel “Bitcoin Timestamping” and “Finality Provider” model, enabling Bitcoin to serve as the ultimate source of trust for other blockchains.
#### **Self-Custodial Bitcoin Staking:**
Babylon Self-Custodial Bitcoin Staking lets Bitcoin holders stake their BTC **directly on the Bitcoin network,** no wrapping, no bridging, and no third-party custody. When user stakes, their BTC stays in their own wallet and is **time-locked** using Bitcoin’s built-in script. They delegate their staked BTC to a Finality Provider, who helps secure Proof-of-Stake (PoS) chains. In return, they earn rewards.
#### **Co Staking:**
In 2025, Babylon introduced **Co-Staking**, a mechanism designed to align incentives between BTC stakers and BABY token holders.
* Staking BTC alone earns a base yield.
* Adding BABY in proportion to BTC (e.g., 1 BTC : 20,000 BABY) unlocks co-staking boosted rewards, \~5-10x the base yield.
* Co-staking is optional but incentivized, as higher BTC:BABY ratios lead to higher reward.
Example:
\
• Alice stakes 6 BTC + 50K BABY → weight 2.5
\
• Bob stakes 6 BTC + 150K BABY → weight 6
If 10K BABY rewards are distributed →
Alice earns 2.94K, Bob earns 7.06K.
## How b14g Merge Marketplace Expands Babylon Co-Staking
#### **The Challenge:**
Co-Staking requires both BTC and BABY in a specific ratio. Many users only hold one asset, BTC **or** BABY, and can’t reach the ratio needed for higher yields. This limits participation and leaves potential rewards untapped.
#### **The b14g Merge Marketplace Solution:**
Merge Marketplace connects BTC and BABY holders so they can **co-stake together** and share rewards.
* **For BTC holders:** Lock your BTC on the Bitcoin network (self-custodial) and match with a BABY holder to unlock higher yield tiers.
* **For BABY holders:** Browse open BTC orders on the marketplace, then match your BABY stake with an order you prefer, earn co-staking rewards without needing to acquire BTC.
#### **Why It Matters**
Merge Marketplace makes Babylon Co-Staking:
* **More inclusive** — anyone can join, even with one asset.
* **More efficient** — reduces idle BTC and BABY liquidity.
* **More secure** — brings more participants into Babylon’s validator network.
* **Better balanced** — supports the ideal BTC:BABY staking ratio (1:20,000).
## How Merge Marketplace works
b14g Merge Marketplace is a set of core smart contracts deployed on Babylon Genesis. It integrates BTC staking and BABY staking to maximize rewards for both stakers.
1. **BTC Staking:** Alice creates a merge order on the b14g Merge Marketplace. Alice then stakes her native BTC on Bitcoin network through Babylon’s native self-custodial staking method.
2. **BABY Staking:** Bob, looking to earn yield on his BABY tokens, matches with Alice’s order by staking his BABY. His BABY is sent directly to the Babylon staking modules.
3. **Reward Distribution:** Here’s how rewards are generated and sent back to users:
1. Alice earns BTC staking rewards.
2. Bob earns BABY staking rewards.
3. The boosted co-staking rewards (from combined BTC + BABY) are automatically split between them.
**Key Points**
* BTC stays timelocked in users' wallet on Bitcoin network, no custody risk.
* All actions (orders, matches, rewards) happens on Babylon Genesis network.
* b14g contracts only coordinate co-staking, never hold user funds.
* Transparent and verifiable, anyone can audit activity on-chain.

How to Stake BTC with CoreDAO via b14g and earn boosted dual-staking rewards
This guide walks you through how to stake BTC self-custodially on Bitcoin network and create a dual-staking position on b14g Merge Marketplace for boosted dual-staking rewards.
{% stepper %}
{% step %}
### **Prepare two wallets**
You will need:
* A **Bitcoin wallet** (for staking BTC).
* A **Core wallet** (for creating dual-staking orders and claiming CORE rewards).
***
**Prepare Bitcoin wallet**
When setting up and funding your Bitcoin wallet, it is important to:
* **not use** a hardware a wallet (such as Ledger), except for **Keystone QR** code, either directly or through other software wallets and
* choose: **Taproot**, **Legacy**, **Native Segwit**, or **Nested Segwit** format
{% hint style="info" %}
Supported Bitcoin Wallet Browser Extension: [Xverse](https://chromewebstore.google.com/detail/xverse-wallet/idnnbdplmphpflfnlkomgpfbpcgelopg?hl=en-GB\&authuser=1), [Unisat](https://chromewebstore.google.com/detail/unisat-wallet/ppbibelpcjmhbdihakflkdcoccbgbkpo), [OKX Wallet](https://chromewebstore.google.com/detail/okx-wallet/mcohilncbfahbmgdjkbpemcciiolgcge).
Supported Bitcoin Hardware Wallet: **Keystone**
*Visit b14g staking interface for the latest list of supported wallets.*
{% endhint %}
***
**Prepare Core wallet**
You’ll need **a small amount of CORE tokens** in your Core wallet to cover **transaction fees** on the Core chain when creating dual-staking orders and claiming CORE rewards.
{% endstep %}
{% step %}
### **Go to the staking page**
Navigate to [**b14g Self-Custodial Bitcoin Staking (Core Chain)**](https://app.b14g.xyz/btcfi/btc?chain=core) interface.
{% endstep %}
{% step %}
### **Connect your BTC wallet**
Connect your **Bitcoin wallet** (compatible wallet as shown on the UI).
{% endstep %}
{% step %}
### **Enter how much BTC you want to stake**
* Input the **amount of BTC** you want to stake. Minimum amount: 0.01 BTC.
* Set your **preferred lock time**. Once locked, your BTC remains unspendable until the time-lock expires.
{% endstep %}
{% step %}
### Choose Staking Strategy
Select the strategy that fits your goal:
* **Fair-Share** Strategy – pick this if you want hands-off, steady, auto-compounding yield.
* **Merge Order** Strategy – choose this if you’re chasing the highest possible APR and don’t mind 0.05% APR (floor reward rate) if no CORE matches.
Click **“Continue”** when ready.
{% hint style="info" %}
You can learn more about each strategy here [Self-custodial BTC Staking (Core chain)](/products/for-btc-holders/self-custodial-btc-staking-core-chain#btc-staking-strategy)
{% endhint %}
{% endstep %}
{% step %}
### **Create your Dual-Staking position (Order)**
Your **Order** is your dual-staking hub on Core chain — it connects your BTC stake with CORE stakers who join later to share boosted dual-staking rewards.
In this step:
* **Connect your Core-compatible wallet** to create your Order. *Each time you lock new BTC, a new dual-staking position (Order) is created.*
* **Set your reward-sharing ratio**: choose how dual-staking rewards will be split between you and future CORE stakers who join your Order. *This ratio cannot be changed later. To adjust, wait until your BTC timelock expires and create a new position (Order).*
* **Choose a validator**: select the Validator you want your BTC stake to support.
* Click **“Create Dual-Staking Position”.**
Once the transaction is confirmed, your Order will be created successfully.
{% endstep %}
{% step %}
### **Review your BTC staking details**
* Review all details carefully: BTC amount, validator, lock duration.
* If everything looks correct, click **“Stake BTC”**
{% endstep %}
{% step %}
### **Wait for Transaction Confirmation**
Your staking transaction will be broadcast to the Bitcoin network. Wait for it to be included in a block and reach **6 confirmations** to finalize your staking.
{% endstep %}
{% step %}
### Activate Your Order on b14g Merge Marketplace
Once your BTC staking transaction is finalized, your **Order** automatically becomes active on the **b14g Merge Marketplace.** Your Order is now open for **CORE stakers** to join and form **dual-staking positions** with you.
{% hint style="info" %}
**Why hasn’t my Order appeared in the marketplace?**
Don’t worry, blockchain transactions take time.
* **Bitcoin staking** need \~6 blocks to confirm.
* Once confirmed, your Order will automatically appear on the Marketplace. You can check your BTC staking status in "[My Portfolio](https://app.b14g.xyz/my-portfolio)" page.

## Step 1: Create a Merge Order via Web UI
Go to [Merge Marketplace](https://app.b14g.xyz/marketplace) and connect your EVM wallet (OKX wallet).
Merge Marketplace screen
On the main screen, find and click the **‘Create Order’** button.
{% stepper %}
{% step %}
### Set reward sharing allocation and Create order
Enter the percentage of rewards you want to keep, and the remainder will go to future CORE holders.\
*Please keep in mind that the reward shared portion only applies to the additional rewards gained through CORE dual-staking. Your original BTC staking rewards stay yours and aren’t affected.*
{% endstep %}
{% step %}
### Copy Reward Address
Reward Address on Core chain (aka **Order address**) will be used to add to BTC staking script in the next step.
{% endstep %}
{% endstepper %}
{% hint style="warning" %}
Each order corresponds to one BTC lock. If you want to execute multiple BTC locks, you'll need to create multiple orders.
{% endhint %}
## Step 2: Run BTC Staking Script
Staking on b14g follows Core’s non-custodial BTC staking model. You can use CoreDAO’s BTC staking tool here: .
{% hint style="info" %}
Just make sure to **replace the reward address with the order address in Step 1.**
{% endhint %}
{% code overflow="wrap" %}
```
// BTC Staking Script
node dist/index.js stake --account tb1qzdvhlak7y8kz0v5hu2tw7qae3969jzrt7rj7n5 --privatekey ${private key} --amount 1000000 --bitcoinnetwork 1 --corenetwork 1 --locktime 1712847585 --rewardaddress ${Order Address} --validatoraddress ${Validator Address}
```
{% endcode %}
{% hint style="success" %}
**That’s it!** Your order is now live. Wait for CORE holders to match with your BTC to enable dual-staking.
{% endhint %}
{% hint style="info" %}
**Why haven't my merge order shown up in marketplace?**
As with all blockchain transactions, it's not instantaneous. Bitcoin deposits take about 6 blocks to confirm. Once confirmed, your order will appear in the marketplace.
Visit the **‘My Portfolio’** tab to view your created orders.

{% endhint %}
***
**Prepare Babylon wallet**
You’ll need **a small amount of BABY tokens** in your Babylon wallet to cover **transaction fees** on the Babylon chain when creating a co-staking order and claiming BABY rewards.
{% endstep %}
{% step %}
### **Go to the staking page**
Navigate to [**b14g Self-Custodial Bitcoin Staking (Babylon)**](https://app.b14g.xyz/btcfi/btc?chain=babylon) interface.
{% endstep %}
{% step %}
### **Connect your BTC wallet**
Connect your **Bitcoin wallet** (compatible wallet as shown on the UI).
{% endstep %}
{% step %}
### **Create your Co-Staking position (Order)**
Your **Order** is your personal co-staking hub on Babylon. It connects your BTC positions with BABY stakers to create co-staking positions and share enhanced rewards.
In this step:
* **Connect your Babylon-compatible wallet** to create your Order.
* **Set your reward-sharing ratio**: choose how co-staking rewards will be split between you and future BABY stakers who join your Order. *You can adjust this ratio later.*
* **Choose a validator**: the BABY staked into this Order will be delegated to this validator.
* Click **“Create Co-Staking Position”.**
Once the transaction is confirmed, your Order will be created successfully.
{% hint style="info" %}
You can create only **ONE order per Babylon wallet**. Any future BTC you stake will be automatically added to this existing order, so this step won’t be required again.
{% endhint %}
{% endstep %}
{% step %}
### **Enter BTC amount & choose Finality Provider**
* Input the **amount of BTC** you want to stake. Minimum amount: 0.005 BTC.
* Then, select the **Finality Provider** you want your BTC stake to support.
* If everything looks correct, click **“Stake BTC”**
{% hint style="info" %}
You can unstake BTC anytime, subject to an **unbonding period of 301 Bitcoin blocks (\~3 days)**.
{% endhint %}
{% endstep %}
{% step %}
### **Agree to Penalties & Bind Wallet**
You’ll need to confirm the pre-signed transactions in your Bitcoin wallet to:
* Agree to Babylon’s slashing terms, and
* Bind your Bitcoin wallet with your Babylon wallet.
{% hint style="info" %}
Your wallet browser extension may not open automatically — you might need to open it manually to approve the transaction.
{% endhint %}
{% endstep %}
{% step %}
### Register your Staking Request
Next, a **staking registration modal** will appear. Confirm the transaction in your Babylon wallet to register your staking request onto Babylon Genesis.
After submission, the Covenant Committee will then verify it and provide the necessary cryptographic signatures that enable on-demand unbonding and slashing mechanisms.
Once verification is complete, you’ll see a **"Verified"** confirmation modal — now you’re ready to stake your BTC.
{% endstep %}
{% step %}
### Stake your BTC
Click **Stake BTC** and sign the transaction in your BTC wallet.
Once you see the **Stake Successful** modal, your BTC has been successfully broadcasted on the Bitcoin network. It will take **\~30 Bitcoin block confirmations** (\~5-6 hours) before your BTC stake becomes **eligible** for voting power, network security contribution, and yield.
{% hint style="info" %}
From here on, your stake is subject to Babylon’s slashing policy — a max of **0.1%** if your selected Finality Provider misbehaves.
{% endhint %}
***
*If you choose to stake later, open the **“Unfinished Stake”** tab on the* [***My Portfolio***](https://app.b14g.xyz/my-portfolio) *page to continue.*
{% endstep %}
{% step %}
### Activate Your Order on b14g Merge Marketplace

{% hint style="info" %}
**Why hasn’t my Order appeared in the marketplace?**
Don’t worry, blockchain transactions take time.
* **Bitcoin staking** need \~30 blocks to confirm.
* Once confirmed, your Order will automatically appear on the Marketplace. You can check your BTC staking status in "[My Portfolio](https://app.b14g.xyz/my-portfolio)" page.

# Staking via CLI
How to Stake BTC with Babylon via b14g and earn boosted co-staking rewards
## b14g Babylon BTC Staking Tool
A CLI tool that lets you stake BTC natively on the Bitcoin network and earn co-staking rewards from the Babylon Genesis network via b14g.
{% embed url="" %}
## Staking Workflow
The `stake` command starts the BTC staking process. It communicates with the Babylon Genesis chain, the Covenant emulators, and the Bitcoin network to:
* Creates your co-staking order (if it’s your first time)
* Builds and registers your staking transaction on Babylon Genesis chain
* Waits for signature verification from the Covenant emulators
* Broadcasts the staking transaction to the Bitcoin network
**1. Create Order**
* First, the system checks if you have an existing order on the b14g marketplace
* If no order exists:
* A new order is created with your chosen validator address specified in the parameters.
* The `btcsharing` percentage defines how rewards are split between you and the Babylon stakers
* This order is linked 1:1 to your Babylon address
**2. Staking Transaction Creation**
* Uses `preStakeRegistrationBabylonTransaction()` from `@babylonlabs-io/btc-staking-ts` to create an unsigned staking transaction with:
* Your staking amount (in satoshis)
* Timelock period (blocks until unlock)
* Finality provider public key
* Your public key
* Available UTXOs (unspent transaction outputs)
* Current Bitcoin tip height
* This function generates:
* Staking transaction
* Slashing transactions
* Unbonding transaction
* Proof of Possession (PoP) signature
**3. Babylon Delegation**
* Creates a delegation message containing:
* Staking transaction data
* Slashing transaction signatures
* Unbonding transaction and signatures
* Proof of possession (PoP) signature
* Broadcasts the delegation to Babylon network through the order smart contract
* Waits for verification (delegation state becomes `VERIFIED`)
**4. Bitcoin Broadcasting**
* Once verified on Babylon, uses `createSignedBtcStakingTransaction()` from `@babylonlabs-io/btc-staking-ts` to:
* Sign the staking transaction with your private key
* Validate that transaction hash matches expected hash from Babylon
* Broadcasts the signed transaction to Bitcoin network
* Your BTC is now locked and staking begins
# Unbonding via Web
How to Unbond BTC with Babylon via b14g
If you want to unbond your BTC, you have **two options:**
**Option 1 – Wait for Timelock to Expire**\
Your BTC will automatically unbond once the timelock ends. After that, it will become **withdrawable** without any extra steps. Simply go to My Portfolio → Withdrawable BTC tab to retrieve your funds. [#withdraw-btc](#withdraw-btc "mention")
**Option 2 – Unbond Early**\
If you prefer to withdraw BTC before the timelock expires, you can unbond your BTC early. This will start a 301 Bitcoin-block unbonding period (\~3 days) before your BTC becomes withdrawable.
***
This guide walks you through how to **unbond early on-demand and withdraw your BTC** via **My Portfolio**.
{% stepper %}
{% step %}
### **Go to My Portfolio**
Visit the [**My Portfolio**](https://app.b14g.xyz/my-portfolio) to view your BTC stakes.
{% endstep %}
{% step %}
### **Connect your wallet**
Connect the following wallets associated with your staking position:
* **Babylon-compatible wallet** – the wallet you used to create the Order (your co-staking position).
* **Bitcoin wallet** – the wallet you previously used to stake BTC linked to that Order.
Once connected, you'll see a breakdown of your BTC staking status:
* **Active BTC** – BTC confirmed after 30 blocks on the Bitcoin network; eligible for voting power, network security contribution, and yield.
* **Pending BTC** – BTC waiting for 30 Bitcoin block confirmations to become active, or currently in the 301 Bitcoin-block unbonding period.
* **Withdrawable BTC** – BTC that has completed the 301 Bitcoin-block unbonding period and is now ready to withdraw.
{% hint style="info" %}
Your staking history is shown based on the **Babylon-compatible wallet** used to create the Order.\
If you staked BTC using multiple **Bitcoin wallets**, reconnect the correct wallet to manage each specific BTC stake.
{% endhint %}
{% endstep %}
{% step %}
### **Manage BTC stakes**
In My Portfolio, select **BTC** under **My Assets** section. Then under the "**BTC (Babylon)**" section, open the **“Active BTC”** tab to view your active staked BTC.
{% endstep %}

How to Stake BABY on b14g and Earn Co-staking Rewards
This guide walks you through how to stake your BABY tokens into a co-staking Order on the b14g Merge Marketplace. By participating, you help secure Babylon Genesis and earn boosted co-staking rewards alongside BTC stakers.
{% stepper %}
{% step %}
### **Prepare Your Babylon Wallet**
Before staking, ensure:
* You have a **Babylon Genesis mainnet wallet** (e.g., Keplr, OKX, Leap).
* Your wallet is **funded with BABY tokens** for staking and gas fees.
*Visit the **b14g app interface** for the latest list of supported wallets.*
{% endstep %}
{% step %}
### **Go to Merge Marketplace**
Navigate to the [**b14g Merge Marketplace**](https://app.b14g.xyz/marketplace/babylon) on the Babylon Genesis chain.
{% endstep %}

4. Confirm the transaction in your Babylon wallet.
Your BABY will be delegated to the validator specified in the Order via Babylon’s Epoching module. It will also be matched with BTC in that Order, enabling you to earn both staking and co-staking rewards.
{% endstep %}
{% step %}
### **Activate Stake & Co-Staking**
The Babylon Genesis chain uses an **epoch-based** staking mechanism. Your staking transaction is confirmed immediately, but your stake becomes becomes **active** only after the **current epoch ends** (every \~1 hour or 360 Babylon Genesis blocks).
You can monitor your **pending** BABY stake either in the Order page *(for a specific co-staking position)*, or in [**My Portfolio**](https://app.b14g.xyz/my-portfolio) page *(for a full overview of your assets).*
Once your stake is **activated**:
* You begin earning **BABY staking rewards**.
* You also receive **co-staking rewards** from the BTC Order (proportional to your share).
{% endstep %}
{% step %}
### Auto-compounding Rewards
Rewards are distributed **every Babylon block**. All rewards are **automatically reinvested** into the order you joined — no manual claiming required. Over time, this increases your **staked balance** and boosts your total yield.

# FAQ
# FAQ: dualCORE
What is b14g dualCORE?
b14g **dualCORE Vault** automates the process of staking your **CORE** across orders on [Merge Marketplace](/products/for-core-holders/core-marketplace) to unlock **highest dual-staking yields**. Rewards are automatically claimed and reinvested daily, compounding your returns over time.
When you stake in the dualCORE Vault, you receive a liquid dual-staking token called dualCORE, which unlocks additional DeFi opportunities. For example, you can trade dualCORE on DEXs or use it as collateral for borrowing and lending *(future dApp integrations are on the way).*
It is perfect for those who want **passive income** without the hassle of managing assets manually—while keeping your assets liquid.
b14g dualCORE Vault is now live on Core mainnet at What is liquid dual-staking? What is dualCORE token?
Staked CORE tokens earn staking rewards, but the trade-off is staked CORE are locked. While staked, CORE cannot be transferred, sold, or used in DeFi.
Liquid dual-staking (via dualCORE tokens) changes that. It lets you earn staking rewards, boosted dual-staking rewards, and daily compound interest without locking up your CORE tokens. With liquid dual-staking, you can transfer, sell, or put your tokens to work in DeFi, all while still earning rewards.
How do dualCORE tokens work?
DualCORE is a liquid dual-staking token on the Core chain, acting as a receipt for staked CORE tokens.
When you deposit CORE into the dualCORE vault, it stakes your tokens in active orders on the b14g Merge Marketplace and issues you dualCORE tokens in return.
Unlike CORE, dualCORE automatically earns staking rewards, boosted dual-staking rewards, and daily compound interest. At any time, dualCORE can be used to redeem the underlying CORE.
Does dualCORE vault lock my CORE assets
No. At any time, dualCORE tokens can be used to redeem the underlying CORE.
How do I claim my rewards for dualCORE?
Rewards are automatically reflected in the value of **dualCORE**.
If you hold dualCORE, you don’t need to claim rewards manually. Instead, the amount of **CORE** that each dualCORE can be redeemed for increases over time.
This means your rewards accumulate through the gradual appreciation of dualCORE relative to the underlying CORE token. The growth reflects staking rewards, dual-staking rewards, and daily compounding.
Example:\
Day 1: 1 dualCORE = 1.2 CORE
...\
Day 10: 1 dualCORE = 2.1 CORE
What can I do with dualCORE?
With normal staking, your CORE token stay locked to earn staking rewards. You can’t do anything with it.
But with liquid dual-staking, you continue to earn staking rewards, dual-staking rewards, and benefit from daily compounding—while still being able to put your dualCORE tokens to work.
Future dApp integrations are on the way. Soon, you can trade dualCORE tokens on a DEX, provide liquidity on a DEX, use your dualCORE as collateral to take out a loan, collateralize a perpetual futures position, and more.
Does dualCORE Vault charge a fee?
To ensure sustainability and responsible operations, dualCORE vault charge 3% fee of vault rewards to cover vault operational costs.
That said, your staked CORE tokens (the principal) and deposit/redeem transactions remain completely fee-free.

# FAQ: Core Marketplace
What is the Core Marketplace?
The b14g Merge Marketplace is an on-chain coordination layer that **connects BTC stakers and CORE stakers for dual-staking.**
It solves a key problem in Core dual-staking: most users only hold one asset (either BTC or CORE), but dual-staking requires both.
The marketplace bridges this gap by allowing:
* BTC stakers to list their BTC lock as an open order.
* CORE stakers to match those orders with their CORE stake.
Once matched, both sides share boosted dual-staking rewards.
In short, **even if you only hold BTC or only hold CORE, the Merge Marketplace lets you earn dual-staking yield without needing both assets.**
b14g Merge Marketplace is now live on Core mainnet at [https://app.b14g.xyz](https://app.b14g.xyz/marketplace)
How does b14g help $BTC holders and $CORE holders?
Core Dual-staking offers high yields but requires both BTC and CORE in a 1:8000 ratio, which many users can’t meet due to limited assets or capital.
b14g Merge Marketplace lets BTC and CORE holders collaborate for dual-staking, so you can:
**For BTC Holders:** You can earn boosted yields without buying more CORE or taking on CORE price change risk.
**For CORE Holders:** If you don’t want to buy BTC right now (maybe because the price seems too high), you can still earn a boosted APY by staking CORE alone.
How does marketplace work?
**Alice** (a BTC holder) creates a merge order, define reward sharing allocation between her and future CORE stakers. Then she stakes her native BTC on Bitcoin network (through Core’s non-custodial mechanism).
**Bob** (a CORE holder) stakes his CORE to match with Alice’s order. His $CORE is auto staked into Core Staking Contract.
🎉Boom, Core dual-staking boost yield is unlcoked.
Rewards are distributed proportionally:
* **Alice:** Earns rewards from her staked BTC.
* **Bob:** Earns rewards from his staked CORE.
* **Dual-Staking Boost Rewards:** b14g takes 20% cut on the boost. The remainder (80%) is shared between Alice and Bob as per reward sharing ratio.
For more details, check out the [Merge Marketplace architecture!](/products/for-core-holders/core-marketplace)
How can I participate?
Check this [User Guide](/user-guide/for-core-holders/guide-core-marketplace).
Are there any requirements for joining Merge Marketplace?
To participate, you must meet the following requirements:
* **For CORE staking:** Stake at least 1 CORE (excluding the transaction fees).
* **For BTC staking:** Stake at least 0.01 BTC (excluding the transaction fees).
Is it audited?
All b14g contracts are audited. Check the reports here. Is my $BTC safe?
Yes.
For BTC staking, we use Core’s BTC non-custodial staking. You keep your BTC in your own wallet on the Bitcoin network with a time lock.
Nobody else can touch your Bitcoin. No bridge. No wrapping. No third-party custody. No external smart contract risk. No slashing risk.
Is my $CORE safe?
Your CORE is automatically staked into the Core staking contract.
Check Corescan. It's public.
What are the conditions for slashing? Will my staked tokens get slashed?
No slashing applied to your staked tokens.
When you use the Merge Marketplace, you follow Core’s staking mechanism, which means you also follow Core’s slashing rules. On the Core Chain network, slashing is only applied to validators for misconduct. Stakers who delegate their CORE or BTC will NOT be slashed, even if a validator is penalized.
What are the important considerations for Locking Periods before staking your BTC?
* **Time Lock Expiration:** When you lock your Bitcoin for staking, it's inaccessible until the staking period concludes.
* **Choosing wisely:** You should select your locking period thoughtfully, considering your investment objectives and risk tolerance. Starting with shorter locking periods can help you become familiar with the process before committing to longer durations.
Please follow these guidelines to ensure smooth transactions when staking or redeeming your Bitcoin.
1. **Avoid Low Gas Fees:**
* We recommend avoiding gas fees that are lower than the current market rate.
* Using a gas fee that is too low, especially during periods of network congestion, may result in your Bitcoin transaction taking an extended amount of time (potentially days) to be confirmed.
2. **Handling Low Gas Fee Situations:**
* If your Bitcoin transaction is delayed due to a low gas fee, consider using a transaction accelerator to speed up the process.
* Several third-party services are available, such as the free viaBTC transaction accelerator (accessible [here](https://www.viabtc.com/tools/txaccelerator)).
* Please research and choose a service that best fits your needs.
While Bitcoin is timelocked, can users unstake CORE that’s dual staked with Bitcoin? If so, do they lose any rewards earned prior to unstaking CORE?
Users can unstake CORE anytime, just as they can when they stake CORE independently.
However, there’s an important detail to note: boosted dual-staking rewards are calculated daily at 00:00 UTC.
If a user unstakes CORE before the daily snapshot, the reward percentage will decrease due to the reduced amount of staked CORE. As a result, they might not earn rewards for the time they staked between the last snapshot and the moment they unstake.
That said, rewards earned prior to unstaking (from earlier snapshots) are not lost.
To maximize rewards, it’s best to unstake right after the daily snapshot at 00:00 UTC.
Why does the APR vary for each order?
The APR for each order depends on several factors, such as:
* The reward-sharing ratio between BTC stakers and CORE stakers
* The dual-staking tier the order belongs to
* The validator’s APY
* The amount of $CORE staked in the order
These variables combine to determine the final APY for each order.
# FAQ: Babylon Marketplace
What is the Babylon Marketplace?
The b14g Merge Marketplace (Babylon) is an on-chain coordination layer that **connects BTC stakers and BABY stakers for co-staking.**
It solves a key problem in Babylon co-staking: most users only hold one asset (either BTC or BABY), but co-staking requires both.
The marketplace bridges this gap by allowing:
* BTC stakers to list their BTC lock as an open order.
* BABY stakers to match those orders with their BABY stake.
Once matched, both sides share boosted co-staking rewards based on the ratio set in the Order.
In short, **even if you only hold BTC or only hold BABY, the Merge Marketplace lets you earn co-staking yield without needing both assets.**
The b14g Merge Marketplace is live on Babylon mainnet at Who should use the Marketplace?
The Babylon Marketplace is designed for:
**BABY holders**
* who want to earn more yield from co-staking
* but do not hold BTC
**BTC holders**
* who want to unlock co-staking rewards
* but do not want exposure to BABY price risk
By matching these two groups, the marketplace creates a **mutually beneficial staking partnership**.
I only hold BABY. Do I need to hold BTC to participate?
No.
The marketplace allows **single-asset participation**.
If you only hold BABY, the system will **pair your BABY with a BTC staker**, enabling you to participate in co-staking without holding BTC yourself.
How is this different from staking BABY normally?
Staking BABY alone only earns **base staking rewards**.
Using the marketplace allows BABY to be combined with BTC to form **co-staking positions**, which can unlock **higher yield opportunities** as per [Babylon network incentives.](https://docs.b14g.xyz/products/for-baby-holders/babylon-marketplace#co-staking)
How does marketplace work?
The **b14g Merge Marketplace** connects BTC holders and BABY holders so they can participate in **Babylon co-staking** together.
**BTC Staking**\
A BTC holder (e.g., Alice) creates a merge order on the marketplace and stakes her **native BTC** through Babylon’s **self-custodial BTC staking** mechanism.
**BABY Staking**\
A BABY holder (e.g., Bob) matches Alice’s order by staking **BABY tokens**, which are sent directly to Babylon’s staking modules.
Once matched, the BTC and BABY form a **co-staking position**, and rewards are shared between both participants according to the **reward-sharing ratio defined in the order**.
**Key Points**
* **BTC remains timelocked in the user’s wallet** on the Bitcoin network, no custody risk.
* All actions (orders, matches, rewards) happen on the Babylon Genesis network.
* **b14g contracts only coordinate matching**, and never hold user funds.
* All activity is **transparent and verifiable on-chain.**
For more details: [Babylon Marketplace docs](/products/for-baby-holders/babylon-marketplace)
How are rewards distributed?
Rewards are distributed proportionally after a 20% performance fee:
* **BTC staker:** Earns rewards from their staked BTC.
* **BABY staker:** Earns rewards from their staked BABY.
* **Co-Staking Boost Rewards:** The boost is shared between BTC and BABY stakers based on the reward-sharing ratio defined in the order.
All reward calculations and distributions are handled **on-chain by the marketplace contracts**.
Why does the APR vary for each order?
APR varies because each order may have different parameters, including:
* **BABY emission** policy from Babylon Genesis.
* **Validator** performance and commission rates.
* **Reward-sharing ratio** set by each order.
* **Co-staking ratio** of BTC and BABY in the position
These factors combine to determine the final APR for each order.

# FAQ: Self-custodial BTC Staking (Core chain)
Is my BTC safe?
Absolutely. You never hand your coins to anyone.
* You sign a locking transaction from your own Bitcoin wallet.
* Your BTC stays at that address under your keys.
* Core Chain simply verifies the lock on-chain to confirm it's valid for securing the network.
* You (and only you) can unlock it once the timelock expires.
There’s no bridge, no wrapped token, and no smart contract risk.
This locking mechanism follows Core chain's native BTC staking standard, end to end.
Does my BTC leave my wallet once staked?
No, your BTC always stays in your own Bitcoin wallet. When you stake, your BTC is locked using a self-custodial Bitcoin staking script that you control. You're not sending it to anyone else.
However, current wallet softwares have not been updated to display staked BTC balances, so it might not show up but rest assured, it’s there, securely locked and verifiable on-chain.
You are the only one who can unbond the stake and withdraw.
How are yields generated?
Your yield comes from two sources:
**BTC staking rewards (Base yield):** Your BTC contributes to Core Chain's Satoshi Plus Consensus, helping secure the Core chain and earning you yield in return.
[**Dual-staking rewards (Boosts)**](https://docs.coredao.org/docs/stake-and-delegate/dual-staking-working)**:** Core Chain offers additional incentives when BTC and CORE are staked together. Through b14g Merge Marketplace, your BTC can be matched with CORE stakers to earn these extra rewards, boosting your APY without requiring you to hold CORE.
What is b14g Merge Marketplace?
The b14g Merge Marketplace is an on-chain coordination layer that connects BTC stakers and CORE stakers for dual-staking.
It solves a key problem in Core dual-staking: most users only hold one asset (either BTC or CORE), but dual-staking requires both. The marketplace bridges this gap by allowing:
* BTC stakers to list their BTC lock as an open order.
* CORE stakers to match those orders with their CORE stake.
Once matched, both sides share boosted dual-staking rewards.
In short, even if you only hold BTC or only hold CORE, the Merge Marketplace lets you earn dual-staking yield without needing both assets.
Is there a minimum or maximum stake?
* Minimum: 0.01 BTC — any less won’t even cover the network fees.
* Maximum: No upper limit—but putting a huge stake into a single validator can dilute your yield—every delegator on that validator shares the same reward pool, so more BTC there means a thinner slice for you.
**Pro tip for large holders:**
* Divide it up. Break your BTC into a few smaller locks and spread them across different validators. That keeps your rewards higher.
* Hit top yield tiers faster. Every lock becomes its own merge order on b14g Merge Marketplace; smaller lock need less CORE to reach the best dual-staking yield tier.
# FAQ: Self-custodial BTC Staking (Babylon)
Is my BTC safe?
Absolutely. You never hand your coins to anyone.
* You sign a locking transaction from your own Bitcoin wallet.
* Your BTC stays at that address under your keys.
* Babylon Genesis simply verifies the lock on-chain to confirm it's valid for voting power and network security contribution.
* You (and only you) can unlock it once the timelock expires.
There’s no bridge, no wrapped token, and no smart contract risk.
This locking mechanism follows Babylon’s native BTC staking standard, end to end.
Does my BTC leave my wallet once staked?
No, your BTC always stays in your own Bitcoin wallet. When you stake, your BTC is locked using a self-custodial Bitcoin staking script that you control. You're not sending it to anyone else.
However, current wallet softwares have not been updated to display staked BTC balances, so it might not show up but rest assured, it’s there, securely locked and verifiable on-chain.
You are the only one who can unbond the stake and withdraw.
How are yields generated?
Your yield comes from two sources:
* **BTC staking rewards:** Your BTC contributes to Babylon’s finality providers, helping secure the Babylon Genesis chain.
* **Co-staking rewards:** Babylon Genesis offers additional incentives when BTC and BABY are staked together. Through b14g Merge Marketplace, your BTC can be matched with BABY stakers to earn these extra rewards, boosting your APY without requiring you to hold BABY.

What is b14g Merge Marketplace?
The b14g Merge Marketplace is an on-chain coordination layer that connects BTC stakers and BABY stakers for co-staking.
It solves a key problem in Babylon co-staking: most users only hold one asset (either BTC or BABY), but co-staking requires both. The marketplace bridges this gap by allowing:
* BTC stakers to list their BTC lock as an open order.
* BABY stakers to match those orders with their BABY stake.
Once matched, both sides share boosted co-staking rewards based on the ratio set in the Order.
In short, even if you only hold BTC or only hold BABY, the Merge Marketplace lets you earn co-staking yield without needing both assets.
Is my BTC ever held by b14g or Babylon?
No.
Your BTC always stays in your own Bitcoin address, locked under Babylon’s native BTC staking mechanism.
b14g contracts only manage reward coordination and co-staking logic, never custody.
How are rewards paid out?
Rewards are distributed per block in **BABY**, the native token of the Babylon Genesis Chain. Rewards are **NOT auto-compounded**, so you’ll need to **manually claim** them.
Why does the APR vary for each BTC lock?
APR depends on multiple factors:
1. BABY emission from Babylon Genesis.
2. Finality Provider performance and commission rates.
3. The reward-sharing ratio set by each BTC Order.
4. The amount of BABY staked that joins your Order — more BABY staked means higher co-staking rewards.
What is slashing, and can it happen to me?
Babylon has a slashing mechanism to keep the network secure. When you stake, you pre-authorize a slashing condition within the self-custodial Bitcoin staking script. If a cryptographic offense occurs, such as a Finality Provider (FP) you staked against double-signing, up to 0.1% of your BTC stake can be slashed (burned) without needing further authorization from you.\
\
Choose reliable finality providers to minimize risk.
What happens if I want to stop staking?
You can unbond your BTC stake anytime you want. This starts a 301-block (\~3 days) unbonding period before your BTC becomes withdrawable.

## 1,请问，质押到b14g里的core，跟质押在官方节点里一样安全吗？讲解安全逻辑
是的。
正如我们之前解释的，**b14g 的所有收益都来自 Core 的双重质押机制**。
这意味着你的 **$CORE 始终是质押在 Core 质押合约中的，以赚取双重质押奖励**。
在 **b14g Merge 交易市场**，质押的具体流程如下：
* 在 **概览（Overview）** 选项卡中，你可以看到 **CORE 从你的钱包转移到市场合约**。
* 在 **内部交易（Internal Txns）** 选项卡中，你可以追踪完整的交易流向：
* **CORE 从你的钱包 → 进入市场合约 → 进入所选订单合约 → 最终流向 Core 质押合约**。
* 在 **日志（Logs）** 选项卡中，你可以看到 **订单将 CORE 委托给了哪个验证者**。
这个过程是 **自动完成的**，并且 **完全由智能合约独立执行，不受外部干预**。
最重要的是，**b14g 并不存储你的资金**，所有质押的 CORE **都直接存放在 Core 质押合约中**。
因此，**在 b14g 质押 CORE，本质上就是在 Core 官方节点中进行质押**。
此外，**b14g 的所有智能合约都已通过 Halborn 审计**，你可以在这里查看审计报告：[\[链接\]](https://docs.b14g.xyz/audits)。
## 2,请问，质押core在btc地址里，core年化率是如何计算的？btc年化率如何计算的？
要理解收益的计算方式，我们先回顾一下 Core 的双重质押收益机制：
* **单独质押 BTC**：你将获得基础质押收益率，大约为 0.14%（具体取决于验证者，例如 Solv 可能提供 0.17%，UTXO 可能提供 0.16%）。
* **单独质押 CORE**：年化收益率大约为 8.6%，具体取决于你选择的验证者。
* **双重质押提升（BTC + CORE）**：如果 BTC 和 CORE 以特定比例（如 BTC:CORE = 1:16,000，对应最高奖励档位）共同质押，你将获得额外的双重质押奖励。
这些额外奖励会提升 BTC 的 APR，而 CORE 的 APR **保持不变**。
#### **b14g 平台的收益计算方式：**
* **BTC 质押**：APR 依据 Core 验证者的质押收益率，并直接发放给 BTC 质押者。
* **CORE 质押**：APR 同样依据 Core 验证者的质押收益率，并直接发放给 CORE 质押者。
* **双重质押提升**：如果质押订单达到理想的 BTC:CORE 比例（如 1:16,000），即可获得来自 Core 双重质押机制的额外收益。
这些额外收益会根据**订单创建者设置的奖励分配比例**，在 BTC 和 CORE 质押者之间分配。因此，BTC 和 CORE 的 APR 都可能会因这些因素而有所提升。
#### **影响每个订单 APY 的因素：**
* 选择的验证者
* 订单创建者设置的奖励分配比例
* 订单所达到的双重收益档位
## 3,请问，把core质押在金库底池里，把质押core在btc的单独地址里，有哪些不同？
当你在 **交易市场** 质押时，你是**直接质押**到 BTC 订单中。
当你在 **金库** 质押时，你是将 **CORE** 存入金库，而金库会**自动将 CORE 质押到 BTC 订单**，无需你手动操作。
那么，为什么需要 **dualCORE 金库**？主要有 **五个关键原因**，这些也是 **交易市场（BTC 订单）与 dualCORE 金库的核心区别**：
**1. 奖励分配：**
* **交易市场（BTC 订单）：** 第一次奖励分配需要 **48 小时**，之后 **每 24 小时** 发放一次。
* **DualCORE 金库：** 奖励**每天增加**，长期收益更高。
**2. 自动复投（Auto-Compounding）：**
* **交易市场（BTC 订单）：** **没有自动复投**，你需要 **手动领取并重新投资** 才能最大化收益。
* **DualCORE 金库：** 奖励会**自动复投**，因此 **APY 高于普通订单**。
**3. 受他人提现影响（收益等级下降）：**
* **交易市场（BTC 订单）：** 你在某个订单中质押 CORE，但如果其他 stakers **大额提现**，可能导致该订单的 **收益等级下降**，你留下的 CORE 也会受到影响，收益减少。
* **DualCORE 金库：** 金库会**自动将资金分配到最高 APR 的订单**，确保你的收益始终最大化，**无需手动操作**。
**4. 订单到期：**
* **交易市场（BTC 订单）：** 每个 BTC 订单都有**固定锁定期限**，一旦到期，你将**无法再获得双重质押奖励**，因为 BTC 已解锁。如果你参与 BTC 订单，**必须注意 BTC 的锁定时间**，到期前提取 CORE 并重新质押到其他活跃订单。
* **DualCORE 金库：** 金库会**自动重新分配资金到活跃的订单**，**无需手动操作**。
**5. 流动性 vs. 非流动性：**
* **交易市场（BTC 订单）：** 质押 CORE 后，你的资产变为 **非流动性**，**无法交易、借贷或参与其他 DeFi**，直到你提现。
* **DualCORE 金库：** 质押 CORE 后，你会收到 **dualCORE 代币**，它是 **流动性资产**，可以：
* 在 **Glyph Exchange** 上**交易**
* 在 **Glyph Exchange** 提供流动性
* 在 **Sumer Money** 上**借贷**
## 4,dualcore的作用是什么？b14g积分的作用是什么？。
**dualCORE** 是 **Core 链上首个流动性双重质押代币**。
当你将 **CORE 代币** 存入 **dualCORE 金库**，你的资产会**自动分配到 b14g Merge Marketplace 上最赚钱的订单**进行质押。
作为回报，你会收到 **dualCORE 代币**，它代表你的 **已质押 CORE 以及所产生的收益**。你可以使用 dualCORE 继续参与 DeFi，例如：
* **将 dualCORE 兑换** 成 CORE 代币
* **使用 dualCORE** 进行 **借贷**
* **在 DEX 流动性池中** 添加流动性
至于 **b14g 积分**，它用于 **奖励用户对平台的贡献**。你使用平台越多，赚取的积分就越多。此外，b14g 积分**未来还将用于空投奖励**。
## 5,希望b14g官方提供简体中文选择。
ok
## 6,把core质押在官方节点里的年化率是8%，把core质押在b14g里的年化率是40%，请问，40%年化率收益，从哪里获得的？
哦，这个问题我在第 2 题已经回答过了。**CORE 的 APR 更高**，是因为它**额外获得了 BTC 质押者的奖励**。
## 7，假设，b14g官方地址打不开了，我们质押在b14g上btc和core，如何赎回到钱包里？我们的币，会损失了吗？请讲解清楚，让用户放心质押。
b14g Merge Marketplace 是一个 **去中心化应用（DApp）**，它作为 **智能合约** 运行在 Core 区块链上。即使 b14g 网站无法访问，你仍然可以**直接与智能合约交互来提取你的 CORE**。网站只是提供了一个更方便的用户界面，来简化操作流程。
此外，我们已经准备了一份**详细指南**，教你如何**无需访问官网，直接从智能合约提现 CORE**。

# b14g Points Season 1 (Ended)
Unlock greater BTC rewards.
{% hint style="info" %}
Point Season 1 has ended. Stay tuned for Season 2.
{% endhint %}
## Overview
The **b14g Point Program** is designed to reward users for their participation in restaking BTC on the b14g platform. By holding vBTC (virtual BTC) and LRT (liquidity reward tokens), users can accumulate points that can be redeemed later. This document explains how the point system works, including how users can earn points through restaking, referrals, social engagement, bonus and boost.
***
## Restaking Points
**Restaking Points** are the primary way users earn rewards on b14g. Points are accumulated based on the amount of vBTC and LRT users hold during the restaking period.
**How Restaking Points Are Earned:**
* **vBTC Points**: For every 1 vBTC held, users will earn 1 point per hour.
* **LRT Points**: Points are also earned for holding LRT, based on the price ratio of vBTC to LRT.
**Example:**
If a user restakes **0.1 BTC** on b14g and receives **0.1 vBTC**, holding it for **3 months (2160 hours)** will accumulate:
Restaking Points = \
`0.1 vBTC * 1 point/hour * 2160 hours = 216 points.`
Points are awarded at least once every 24 hours based on a system snapshot. Users will continue to earn points as long as they hold vBTC or LRT and the restaking period remains active.
If the user no longer holds vBTC or LRT, or the restaking period ends, they will stop earning points.
***
## Referral Points
Users can earn **Referral Points** by inviting others to restake on b14g. The referrer will receive 10% of the restaking points earned by their referee, with no time limit—this reward is ongoing as long as the referee continues restaking.
**Example:**
If a referee earns 500 restaking points, the referrer will earn **50 referral points** (10% of 500) automatically.
***
## Social Points
Users can also earn points by engaging with b14g's social platforms. Joining Telegram, Discord, or Twitter will reward **100 points** per platform. This is a one-time reward for each platform.
***
## Bonus
The b14g platform has set aside a portion of its total token supply for **reward redemption**, where users can convert their accumulated points into **$B14G tokens**. The number of tokens a user receives depends on the platform’s **Total Value Locked (TVL)** at the time of the redemption. As the TVL increases, more tokens will be distributed, ensuring that as the platform grows, users are incentivized to participate in a more decentralized and active network.
This approach encourages broader participation and rewards users more generously as the ecosystem becomes stronger and more secure.
**TVL-Based Token Redemption:**
* **<10M TVL**: 10% of the total token supply will be redeemed.
* **25M TVL**: 12% of the total token supply.
* **50M TVL**: 14% of the total token supply.
* **100M TVL**: 16% of the total token supply.
* **250M TVL**: 18% of the total token supply.
* **>500M TVL**: 20% of the total token supply.
**Example:**
If the TVL at the time of the reward redeemption is **280M**, then **18%** of the total B14G tokens will be redeemed to users based on their accumulated points.
***
## Boost
Early participants in the restaking process will receive a **Boost** Multiplier, allowing them to accumulate points at a faster rate. The earlier the user restakes and the lower the TVL, the higher the multiplier they receive.
**TVL-Based Boost Multiplier:**
* **<10M TVL**: 10x multiplier.
* **10M - 25M TVL**: 8x multiplier.
* **25M - 50M TVL**: 6x multiplier.
* **50M - 100M TVL**: 4x multiplier.
* **100M - 250M TVL**: 3x multiplier.
* **250M - 500M TVL**: 2x multiplier.
* **>500M TVL**: 1x multiplier (no boost).
**Example:**
If a user restakes when the TVL is **22M**, they will receive an **8x multiplier** on their points. If the TVL later increases to **30M**, their new restaking points will be calculated with a **6x multiplier**, but the points earned under the 8x multiplier remain unchanged.
***
## Conclusion
The b14g Point Program provides multiple ways for users to earn rewards by participating in the ecosystem through restaking, referrals, and social engagement. Early participation is highly encouraged through Boost multipliers, and the Bonus ensures that users earn more as the platform grows.

# Bittery Integration
## Bittery Action Widget
```
https://partner.b14g.xyz/ibittery
```
## Bittery Stats API
This part outlines the API endpoints and data structures for retrieving information related to the current Bittery staking round.
### 1. Get Total BTC Deposited
**API:**
```
https://api-staging.b14g.xyz/restake/middleware/lottery/current-round
```
**Example Response:**
```
{
"timestamp": "1744380781",
"round": "2",
"startDate": "1744603223",
"users": [
{
"address": "0x8a9570448d28d24219f83cc2f87ab55ccf35e437",
"totalReward": "0",
"totalBtc": "500000"
},
{
"address": "0x83b7a3930b509a2f0c9e9de4e39ceefc4ac08e47",
"totalReward": "0",
"totalBtc": "1000"
}
],
"receivers": [
],
"totalReward": "24953207489908548"
}
```
The users array contains a list of participants. Each user object includes:
* `address`: The Ethereum address of the user.
* `totalBtc`: The total amount of BTC deposited by the user in this round (unit: wei).
To calculate the total BTC deposited across all participants in the current round, sum the totalBtc values from each element within the users array.
Based on the example response above:
```
Total BTC Deposited (wei) = 500000 + 1000 = 501000
Total BTC Deposited = 501000 / 1e8 = 0.00501 BTC
```
### 2. Get Total Reward
**API:**
```
https://api-staging.b14g.xyz/restake/middleware/lottery/current-round
```
**Example Response:**
```
{
"timestamp": "1744380781",
"round": "2",
"startDate": "1744603223",
"users": [
],
"receivers": [
],
"totalReward": "24953207489908548"
}
```
The `totalReward` field represents the estimated total reward for the current round (unit: wei).
Based on the example response above:
```
Total Reward (wei) = 24953207489908548
Total Reward = 24953207489908548 / 1e18 = 0.0224953207489908548 CORE
```
### 3. Get User Reward Contributions
**API:**
```
https://api-staging.b14g.xyz/restake/middleware/lottery/list-yieldBtc/${address}
```
**Example Response:**
```
{
"yieldBtcs": [],
"depositedYieldBtcs": [
{
"isDeposited": true,
"tokenId": "25",
"order": {
"btcAmount": "100000",
"roundReward": "10297279194593749",
...
}
},
{
"isDeposited": true,
"tokenId": "28",
"order": {
"btcAmount": "100000",
"roundReward": "10297279194593749",
...
}
},
],
"pendingReceivers": [],
"totalBtcDeposited": "500000"
}
```
This API returns a list of the user's deposited BTC contributions (depositedYieldBtcs). Each element in the `depositedYieldBtcs` array represents a deposit and includes details such as the deposited `btcAmount` and the corresponding `roundReward` for that deposit (unit: wei).
To calculate the total reward contributions for a specific user, sum the `roundReward` values from each element within the `depositedYieldBtcs` array.
Based on the example response above:
```
User Reward Contributions (wei) = 10297279194593749 + 10297279194593749 = 20594558389187498
User Reward Contributions = 20594558389187498 / 1e18 = 0.02059455838 CORE
```
### 4. Calculate Win Chance
The win chance can be estimated by dividing the `Total Reward` by the `User Reward Contributions`.
**Formula:**
```
Win Chance = Total Reward / User Reward Contributions
```
Using the example values from above:
```
Win Chance ≈ 0.0224953207489908548 CORE / 0.02059455838 CORE ≈ 1.09
```
This can be interpreted as approximately a **1 in 1.09** chance.
### 5. Get User BTC Deposited
**API:**
```
https://api-staging.b14g.xyz/restake/middleware/lottery/list-yieldBtc/${address}
```
**Example Response:**
```
{
"yieldBtcs": [],
"depositedYieldBtcs": [],
"pendingReceivers": [],
"totalBtcDeposited": "500000"
}
```
This API returns details of a specific user's BTC deposits. The `totalBtcDeposited` field represents the total amount of BTC deposited by the user across all their contributions in the current round (unit: wei).
Based on the response above:
```
User BTC Deposited (wei) = 500000
User BTC Deposited = 500000 / 1e8 = 0.005 BTC
```
