BTC Fair-Share Vault
BTC Fair‑Share Vault is a non‑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.

How are yields generated?
Base staking yield (securing Core Chain)
The vault 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:
You lock your BTC and it shows up as an open order on b14g Merge 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 0.1% floor rate if no match.
Claimable CORE daily
Fair-Share
Same BTC lock mechanism, but with a hands-off approach. Vault 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 daily
Key points to remember:
Your BTC stays non-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
Lock BTC You sign one Bitcoin transaction that locks your coins for a period you want. Your BTC stays in your own wallet—non-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.
Vault pairs BTC with CORE The vault adds CORE from b14g’s dualCORE vault, so the BTC meets Core Chain’s dual‑staking requirements, earning boosted yields. The combined stake is spread across high‑yield Core validators.
Auto‑compound CORE rewards are converted to dualCORE and paid out daily. Holding dualCORE automatically re‑invests those rewards.
Unlock BTC When your timelock ends, you broadcast a normal Bitcoin spend back to yourself. You keep all earned dualCORE.
