# 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.md). 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.md) 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.md), 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.
