Introducing Clementine Bridge: Citrea Deploys First Complete BitVM Bridge Design on Testnet

Citrea's Clementine Bridge marks the first time that a fully programmable layer is tested for settling on Bitcoin.

GEORGE TOWN, Cayman Islands, April 21, 2025 /CNW/ -- Citrea, the first ZK rollup to enhance capabilities of Bitcoin blockspace and enable Bitcoin applications (₿apps), has successfully deployed its Clementine Bridge, the first complete BitVM bridge design on Bitcoin Testnet. Citrea has also recently revealed Clementine's whitepaper, marking the first real-world implementation of a BitVM-based bridge which extends BTC's utility to decentralized finance in the most Bitcoin-secured and native way possible. With Clementine's testnet deployment, Bitcoin is for the first time tested for optimistically verifying a fully programmable layer. The Clementine whitepaper is currently the only documentation of how to use BitVM in a bridge design with clear solutions toward a secure and efficient bridge implementation.
