tBTC Decentralized Bitcoin Bridge

Acre has selected a permissionless, decentralized bridged bitcoin (tBTC) as part of the infrastructure behind the Acre protocol.

Built atop tBTC, Acre selected a non-custodial and decentralized bitcoin tokenization service for launch allowing mainnet bitcoin to be securely bridged on Ethereum and beyond. Maintained and operated by the Threshold Network DAO, it relies on a system of decentralized nodes rather than a single centralized custodian. Supported on the largest DeFi, restaking and bitcoin L2 protocols, this choice for a permissionless bridge increases the different vault partners for Acre without sacrificing security.

Security

Fully backed and redeemable for BTC, this bridge requires a threshold majority signature (51 out of 100) before node operators mint or redeem the underlying asset. You can learn more about tBTC minting here.
