Circle to Reduce Legacy USDC Cross‑Chain Transfer Limits from Oct. 31, 2026
Current overview (not historical)
Circle announced that starting October 31, 2026 it will begin reducing the burn limits for its legacy CCTP V1 contract, and will suspend the old contract entirely on December 1. The legacy contract will see its transfer capacity gradually tightened, with new activity phased out before the full pause; however, any pending redemptions will remain available and minting capacity will stay above the total outstanding proof amount. Applications that currently use V1 must update their contract calls and APIs, as CCTP V2 is not backward compatible with the legacy system. This move signals Circle’s intent to phase out the older cross‑chain transfer mechanism in favor of the newer, more efficient protocol while ensuring a smooth transition for users and developers.

Report first recorded Oct 30, 13:15
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.
