CCIP's logo

CCIP is the Chainlink Cross-Chain Interoperability Protocol. Chainlink unlocks an easier way to build cross-chain applications and services with CCIP, a secure, reliable, and easy-to-use interoperability protocol. CCIP provides onchain developers with a secure, easy-to-use interface to build secure applications that can send messages, transfer tokens, and initiate actions across blockchains. The protocol is powered by Chainlink decentralized oracle networks, which have a proven track record of securing tens of billions of dollars and enabling over $8 trillion in on-chain transaction value. CCIP was designed with ease of use for developers in mind, embedding robust security into the protocol through the Risk Management Network, and being underpinned by Chainlink's time-tested oracle infrastructure. The era of secure blockchain interoperability has arrived.
