What Is tBTC?
tBTC is a decentralized Bitcoin bridge that lets BTC holders use their bitcoin within Ethereum’s DeFi ecosystem without trusting a single custodian. Each tBTC token is backed 1:1 by real Bitcoin held in multi-party custody controlled by randomly selected, collateralized node operators known as signers.
How tBTC Works
Users send BTC to a threshold-secured wallet generated by a group of randomly chosen signers. Once the deposit is confirmed on Bitcoin, an equivalent amount of tBTC is minted on Ethereum. Redemption works in reverse: burning tBTC triggers a BTC release from the signer group.
Signers are required to post ETH collateral (overcollateralized) as a security bond. If a signer misbehaves or fails to release BTC, their bond is slashed and used to compensate the depositor, ensuring trust-minimized operation.
The Threshold Network
tBTC v2 is operated by the Threshold Network, formed from the merger of the NuCypher and Keep networks in 2022. Threshold uses a mix of Distributed Key Generation (DKG) and threshold cryptography to eliminate single points of failure. T is the native governance token of the network.
tBTC vs. WBTC
Unlike WBTC, which relies on a centralized custodian (BitGo), tBTC has no single entity controlling the Bitcoin. The trade-off is slightly higher complexity and redemption latency vs. WBTC’s simpler peg mechanism.
Use Cases
- DeFi collateral: Use BTC as collateral in Ethereum lending protocols like Aave and MakerDAO
- Curve pools: tBTC/WBTC/sBTC pools on Curve Finance for deep liquidity
- Trustless BTC yield: Earn yield on Bitcoin without entrusting a centralized custodian
