BlockBeats News, August 7th, according to official sources, the first trustless multi-chain Bitcoin cross-chain bridge based on BitVM2 technology, Fiamma Bridge, recently announced its official launch on the mainnet, with Aptos being one of the first supported core blockchains.

Through Fiamma Bridge, users can securely convert Bitcoin into 1:1 anchored on-chain assets, FiaBTC, and participate in DeFi applications, earn rewards, engage in lending, and make payments on the Aptos chain, achieving a truly non-custodial cross-chain experience. Unlike traditional cross-chain solutions, Fiamma leverages BitVM2, combined with zero-knowledge proofs, Taproot protocol addresses, and on-chain dispute resolution mechanisms, to ensure that cross-chain operations are verifiable, secure, and fully controlled by users.

This integration injects new Bitcoin liquidity into the Aptos ecosystem, transforming BTC from a mere store of value asset into a productive asset that can be efficiently utilized on-chain, accelerating the implementation of Aptos' BTCfi strategy and further expanding the boundaries of on-chain financial applications.
