• Circle set December 1 as the deadline to pause V1 contracts of its USDC cross-chain transfer protocol.
• Burn limits will begin decreasing on October 31, giving integrators 95 days to migrate to the new standard.
• Aptos, Noble, and Sui are the only chains that rely exclusively on the V1 network and will be left without a native route once the contracts are closed.

Throughout November, the company will progressively reduce that capacity until the contracts are definitively paused on December 1. Any integration still pointing to V1 on that date will no longer be able to move USDC between networks.
