Cross-Chain Token Standard
This section explains the Cross-Chain Token (CCT) standard, a Chainlink CCIP feature for cross-chain token transfers.
Learn how token pools (lock/release and burn/mint) operate, what token issuers configure for production, how AdvancedPoolHooks adds transfer controls to a token pool, how token pool rate limits bound cross-chain flow, and how to migrate token pools from v1.x to v2.0.

What the CCT standard is, its core components and token handling mechanisms, token compatibility requirements, the token pool features new in CCIP 2.0, and token pool rate limits and gas limits.
Token Issuer Guide
Operational guidance for token issuers: registering a token, deploying and configuring its token pools, testing, operational security, and custom pools.
Advanced Pool Hooks
How AdvancedPoolHooks adds sender allowlists, ACE policy checks, and additional CCV requirements to a token pool.
Rate Limits
How token pool rate limits bound the volume of cross-chain token flow per lane, and how to inspect, update, and lock down limits.
