Bitcoin Rollup project Citrea has deployed the Clementine bridge on the Bitcoin testnet, utilizing the BitVM2 programming language, aiming to introduce Bitcoin (BTC) into the DeFi environment in a trust-minimized manner.
Citrea stated, "The secure bridging between Bitcoin and layer-2 protocols has always been a bottleneck for using BTC in programmable environments." Clementine resolves this issue by allowing multiple withdrawals using a single collateral.
Additionally, Clementine employs the BitVM2 version, upgrading operations, and enabling any participant to challenge suspicious transactions.
