Circle starts cutting legacy USDC app transfer limits on October 31

  • —Burn limits in CCTP V1 will decline from Oct. 31, with transfer volume intended to reach zero
  • —Legacy CCTP V1 contracts will be fully paused on Dec. 1, 2026
  • —Pending redemptions stay available; Circle will keep minting allowances above pending attestations
  • —Migration to V2 requires new TokenMessengerV2 and MessageTransmitterV2 addresses and API changes
Why it matters: Apps that fail to migrate to CCTP V2 will lose the ability to move USDC across blockchains after Dec. 1.
