Chainlink has integrated Coinbase's wrapped Bitcoin token, cbBTC, into the Monad blockchain, unlocking over $5 billion in Bitcoin liquidity for Monad's DeFi ecosystem. This integration, announced on March 2, 2026, allows decentralized finance applications on Monad to access cbBTC directly, facilitating Bitcoin-backed lending and borrowing applications. The integration is powered by Chainlink's Cross-Chain Interoperability Protocol (CCIP), enabling seamless cross-chain transfers from Coinbase's Base network to Monad without third-party intermediaries. Monad, a high-speed EVM-compatible blockchain, now offers developers the ability to build Bitcoin-denominated financial products, such as lending protocols and spot trading pairs, directly on the network. Projects like Curvance and Neverland have already begun utilizing cbBTC markets. The integration comes at a time when Bitcoin-backed assets are increasingly used as collateral in DeFi, providing a secure and efficient venue for deploying capital.
