BTC Merge Order

Merge Order strategy lets you lock your BTC non-custodially on Bitcoin network to secure Core Chain and earn yields. Rewards paid in claimable CORE token daily.

You stay non-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 0.1%.

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.

How Merge Order Works

Lock Your BTC Sign a Bitcoin timelock transaction for your chosen duration.
Set Your Reward Split Choose how to divide boosted rewards between you and the eventual CORE match (e.g., 50%/50%).
Pick a Validator Select a Core Chain validator to receive the combined stake.
Post on Merge Marketplace Your BTC lock position appears as an open order on b14g Merge Marketplace, waiting for CORE partners to stake their CORE, forming a dual-staking pair.
Wait for CORE Match A CORE holder accepts your split terms; their CORE is paired with your BTC.
Start Earning The combined stake earns dual-staking APR. Rewards (in CORE) are claimable daily.
Unlock & Withdraw After the lock ends, your BTC is released, you can withdraw it back to your wallet; you keep all claimed CORE.

What Affects Your APR?

Your Merge Order APR depends on three factors:

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.
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.
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.

Too much to manage?

Try the Fair-Share vault instead. It's a “hands-off,” steady-earning mode of Merge Order. Your BTC still becomes an open order on the marketplace, but b14g handles the CORE matching for you. If enough CORE is available to match all BTC stakes, everyone enjoys the top‑tier APR; if not, rewards are averaged so nobody drops to the 0.1 % floor.

In short, you enjoy a steady APR without worrying about splits, tiers, or validator crowding.

Bonus: Rewards in Fair-Share vault are auto-compounding, so your earnings grow on their own.
