Ethereum layer-2 network Celo has integrated Chainlink’s CCIP protocol for cross-chain interoperability, aiming to enhance efficiency and liquidity for investors. This move is expected to accelerate the growth and adoption of the Celo ecosystem, as cross-chain interoperability is a core focus in the blockchain industry. Chainlink's CCIP protocol acts as a 'layer 0' protocol for cross-chain communication between public blockchains and traditional financial architecture. In 2023, Chainlink successfully conducted a pilot test with SWIFT, the international messaging protocol for interbank communication, highlighting potential synergies between blockchain, traditional banks, and international business.
