Circle will discontinue support for USDC and CCTP V1 on the Noble blockchain as it transitions to the next-generation CCTP V2 cross-chain protocol. Noble will not receive CCTP V2 support, despite the new version offering faster finality and enhanced security. New USDC minting on Noble through Circle Mint will stop on October 13, and the USDC contract on Noble will be suspended on January 12, 2027. Circle said all USDC on Noble remains redeemable at a 1:1 ratio.
