The development firm behind the Chainlink protocol and its native LINK token has gone live with its cross-chain protocol, aimed at providing interoperability between traditional financial firms and both public and private blockchains.
In a July 17 post on the Chainlink blog, Chainlink Labs' Chief Product Officer Kemal El Moujahid announced that its Cross-Chain Interoperability Protocol (CCIP) has launched under early access on Ethereum, Avalanche, Polygon, Arbitrum, and Optimism.
Developers on these platforms will have access to CCIP on their respective testnets on July 20.
CCIP is an interoperability protocol that allows enterprises to transfer data and value between public or private blockchain environments directly from their backend systems.
Chainlink’s interoperability solution uses Swift’s messaging infrastructure, which is used by over 11,000 banks around the world to facilitate international payments and settlement.
