CCIP 2.0: Chainlink's New Verifier System Risks Transfer Delays

Chainlink's CCIP 2.0 has introduced a new feature that allows issuers to require an additional verifier for cross-chain token transfers.

This optional Cross-Chain Verifier (CCV) sits alongside the default Committee Verifier, which consists of 16 independent node operators.

If a verifier becomes unresponsive, it can stall dependent messages and leave tokens locked or burned on the source chain pending delivery.

While this gives issuers more control over token distribution, it also risks leaving transfers stranded between chains without an automatic return solution.
