# tBTC Decentralized Bitcoin Bridge

Built atop [tBTC](https://tbtc.network/), 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](https://docs.threshold.network/), 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](https://docs.threshold.network/applications/tbtc-v2).
