Circle Begins CCTP V1 Wind-Down Amid Doc Mismatch

Burn limits on Circle's legacy USDC bridge began falling on October 31, and the V1 contracts pause on December 1. On the same migration page, a block of instructions written for AI coding assistants still says Noble, Sui and Aptos "still require V1." Circle's own release notes say two of those three chains moved to V2 weeks ago. Circle's legacy cross-chain transfer protocol entered its final month today. From October 31, burn limits on CCTP V1 start falling toward zero, and on December 1 the V1 contracts pause. Any app still using them will stop moving USDC between chains.
