Circle to Cut USDC Transfer Limits on Oct. 31 as Legacy CCTP V1 Winds Down

Circle announced that from Oct. 31 it will lower the burn limits of its Cross‑Chain Transfer Protocol version 1 (CCTP V1), and will pause the legacy contracts entirely on Dec. 1. Applications still using V1 must update their contract calls and APIs because CCTP V2 is incompatible with legacy integrations. During the wind‑down Circle will keep pending redemptions available and maintain minting capacity above the total of pending attestations, allowing those redemptions to be processed before the full pause. The staged reduction in burn limits will gradually reduce transfer capacity throughout November, ultimately reaching zero before the contracts are fully paused.
