USDC's original cross-chain bridge started shutting down today. From Oct 31, Circle is cutting the burn limits on version 1 of its Cross-Chain Transfer Protocol (CCTP), the rails that destroy USDC on one chain and mint it fresh on another. Capacity keeps shrinking through November. On Dec 1, the V1 contracts get paused. Any app or bridge still wired to them simply stops moving USDC between chains. What doesn't change: • USDC itself keeps working • Circle says funds stay accessible and transfers already in flight can still be completed • The newer version already runs on 27 chains The real deadline is earlier than it looks. With limits tightening all month, teams that haven't migrated could run into capacity walls well before December. Circle is also leaving Noble, the Cosmos USDC hub: new minting there stopped Oct 13, and redemptions end Jan 12, 2027. For scale: stablecoin supply sat at $300.5B on Oct 30, down 0.3% in a day.
