Circle will halt new USDC minting on the Noble blockchain on Oct. 13, 2026 and pause the chain's USDC contract on Jan. 12, 2027, with a manual redemption portal opening Jan. 13, 2027. Noble will not receive CCTP V2, ending the native issuance route that carried USDC across Cosmos since late 2023.
Circle will stop minting USDC on the Noble blockchain through Circle Mint on Oct. 13, 2026, then pause the chain's USDC contract outright on Jan. 12, 2027, ending the native issuance route that has carried the stablecoin across Cosmos since late 2023. Noble will not receive CCTP V2, the upgraded cross-chain transfer protocol Circle is rolling out elsewhere, the issuer said in a Sept. 10 blog post.
"We are discontinuing support for USDC and CCTP V1 on the Noble blockchain as part of our broader transition to CCTP V2, a next-generation cross-chain protocol with faster finality and stronger security," Circle said in the post. The company added that its wider Cosmos presence is unchanged, pointing to Injective and other IBC-connected chains as active partners.
The wind-down runs on four dates. Circle Mint customers keep normal Noble access through Oct. 12, 2026. CCTP V1 burn limits begin shrinking Oct. 31, 2026, and reach zero on a rolling basis; one account of the schedule puts a full contract pause at Dec. 1, 2026, ahead of the Jan. 12, 2027 contract halt. Circle will snapshot remaining Noble balances on the pause date and open a manual redemption portal on Jan. 13, 2027 for wallets that clear its compliance and security checks. USDC stays redeemable 1:1 throughout, and the token traded near its $1 peg on Sept. 10, up 0.0113%, per the issuer's post.
The stakes are measured in routing, not in USDC's $74.31 billion market cap. Noble was the issuance layer that let USDC enter Cosmos through the Inter-Blockchain Communication protocol, propagating to dozens of linked chains. Removing it forces every Cosmos protocol that touches USDC to find a new path before the contract goes dark, and Circle has said it will publish a list of known exit venues rather than run its own exit interface.
Circle recommends three paths during the roughly three-month transferable window from Oct. 13, 2026 to Jan. 12, 2027: deposit into a centralized exchange that supports Noble USDC, swap on a Noble DEX, or burn through CCTP V1 to a destination chain that still accepts it. The third option degrades on a schedule. After Dec. 1, 2026, CCTP exits may narrow to chains still accepting CCTP V1 burns, which makes the early part of the window the only period when all three routes are reliably open.
Developers carry a separate deadline. Circle wants Noble removed as a supported CCTP V1 route before Jan. 12, 2027, so any integration still pointing at that route stops working when the pause lands. USDC remains accessible through Circle Mint and Cosmos wallets including Keplr and Cosmostation during the transition, but cross-chain movement through CCTP V1 decays steadily before going dark.
Noble is not alone on the deprecated standard. Aptos and Sui also remain exclusively on CCTP V1 and are excluded from CCTP V2, though their exposure is narrower — each is a single network, while Noble functioned as shared infrastructure for a multi-chain ecosystem. Circle has said it is working with Noble and Cosmos teams on an interim routing solution to keep USDC transactions flowing through alternative pathways.
The exit was visible before it was official. Coinbase halted USDC deposits and withdrawals on the Noble network on Aug. 17, 2026, nearly a month before Circle's announcement, a signal that large venues were already repricing the chain's role.
For Cosmos-based DeFi, the loss is a convenience that had become a dependency. Protocols that treated Noble-routed USDC as a default settlement asset now need replacement liquidity, and the migration itself is the risk: holders moving size through DEX swaps or exchange deposits face slippage and withdrawal limits that did not exist when native issuance was live. Circle's manual redemption portal, opening Jan. 13, 2027, is a backstop rather than a plan — it requires wallets to pass compliance and security checks, and it arrives after the contract has already paused.
Circle's own numbers barely register the change. USDC carries a $74.31 billion market cap, and Noble is a comparatively small distribution channel within it. The issuer's broader business has been expanding: it agreed to acquire Singapore-based payments platform Tazapay and extended a partnership with BNY Mellon, which now offers digital asset custody for USDC. Those moves point to institutional payment rails, not Cosmos interchain routing, as the priority.
The read-across for Cosmos is that native issuance is a privilege granted by an issuer, not a property of the chain. Noble built its product around being the place where USDC entered the ecosystem; that product now has an end date. The next test comes Oct. 13, 2026, when minting stops and the only remaining question is how much of Noble's USDC supply finds a new home before Jan. 12, 2027.
