If you use USDC for cross-chain transfers, one thing to check soon is whether the app has migrated from the legacy CCTP routes.
Circle’s retirement schedule is approaching: starting October 31, 2026, CCTP V1 will gradually reduce its burn limits. Under the official plan, the legacy contracts will be paused on December 1, and integrations that still point to these contracts will stop supporting cross-chain USDC transfers.
One easy-to-miss detail is that V2 uses separate contracts and APIs and is not backward-compatible with V1. Wallets and cross-chain apps can’t just change the version name in the interface; the underlying calls also need to be migrated. Before using an app, ordinary users can check its migration announcement and confirm that the selected chains and transfer route support the new version. Don’t assume a route is available just because the page still opens.
This notice applies to legacy cross-chain infrastructure and does not mean that all USDC transfers will be paused. Cross-chain transfers involve risks related to contracts, routes, and addresses. Verify the destination network before proceeding, and test with a small amount first.
