Chainlink Cross-chain Interoperability Protocol (CCIP)

Chainlink CCIP is a blockchain interoperability protocol that enables developers to build secure applications that can transfer tokens, messages (data), or both tokens and messages across chains.

CCIP enables three main actions:

  • Arbitrary messaging: Send arbitrary data (encoded as bytes) to a receiving smart contract on a different chain.
  • Token transfers: Transfer tokens to a smart contract or an externally owned account (EOA).
  • Programmable token transfers: Simultaneously transfer tokens and arbitrary data in a single transaction.

To use CCIP services, you need to have LINK available to pay node operators, a cost referred to as CCIP fees. See the token contracts for LINK on Linea.
