Circle announced it will discontinue USDC support and retire the Cross-Chain Transfer Protocol V1 on Noble, effectively removing Noble, Aptos and Sui from the upgraded CCTP V2 network. The wind-down follows a staged timeline: new USDC minting through Circle Mint on Noble ends October 13, 2026; CCTP V1 burn limits begin declining on October 31, 2026; and Circle plans a final contract pause and snapshot of remaining Noble balances on January 12, 2027, with manual redemptions opening January 13 under compliance checks. Circle will not upgrade Noble to CCTP V2, leaving holders, exchanges and integrators to migrate or remove Noble routes before the deadline.
The practical impact concentrates in the Cosmos ecosystem where Noble had acted as the canonical USDC issuance point since late 2023. DeFiLlama shows Noble holds about $102.2 million in stablecoins, with USDC representing more than 90% of that supply, leaving roughly $92 million of USDC subject to the migration. Ondo US Dollar Yield is the next-largest stablecoin on Noble at nearly $8 million. Circle’s staged exit keeps USDC transferable on-chain during the period but steadily reduces legacy cross-chain capacity; after December 1, exits via CCTP may be limited to destination chains still accepting V1 burns, and by the Jan. 12 pause all Noble CCTP routes and the USDC contract will be withdrawn from Circle Mint.
Cosmos Labs has coordinated a migration route through Injective, where Circle already issues native USDC. Starting September 11, Skip:Go enables holders to swap USDC.n on Noble for USDC.inj on Injective, supporting an initial set of chains including dYdX, Osmosis, Cosmos Hub, Terra 2.0, Neutron, ZIGChain, XPLA and Initia; other chains must ensure IBC relayers to Injective before joining. The migration flow reduces user friction by requiring a signed transaction on the origin chain and another on Injective while a relayer handles the intermediate CCTP steps, but the bulk of work falls to protocols and infrastructure providers that must update markets, liquidity pools, wallets and routing logic.
Circle will snapshot Noble balances at the January pause and allow manual redemptions only for wallet-controlled addresses that pass compliance and security checks; tokens left inside liquidity pools or smart contracts at snapshot time may not be eligible. Circle will not provide an exit interface, so holders must use exchanges, decentralized exchanges or compatible CCTP apps to leave Noble earlier. Given exchange delistings already in effect—Coinbase stopped Noble USDC deposits and withdrawals on August 17—Cosmos stakeholders are being urged to prioritize migration before the burn-limit reductions on October 31 rather than relying solely on the January cutoff.
