This section explains the Cross-Chain Token (CCT) standard, a Chainlink CCIP feature enabling secure and reliable cross-chain token transfers.

Learn how token pools (lock/release and burn/mint) operate, what token issuers configure for production, how token-pool rate limits bound cross-chain flow, and how to migrate pools from CCIP v1 to v2.
