According to BlockBeats,October 30，USDC issuer Circle noted that the cross-chain transfer protocol CCTP V1 legacy version will, effective October 31, 2026, reduce the per-transaction burn limit and, over approximately 1 months, gradually tighten transfer capacity, until December 1 the relevant contracts are paused. Integrations still pointing to the legacy contracts will then no longer be able to conduct cross-chain transfers USDC. Circle stated that pending redemptions can still be completed and that it will maintain minting capacity above the total amount of pending attestations, ensuring that all redemptions can be processed before the pause. Developers need to migrate to what is now called CCTP V2.
According to another Circle announcement, on the Noble chain,USDC and CCTP V1 will be separately sunset. Circle Mint closed new minting on that chain on October 13, with the redemption window open until January 12, 2027, after which the process will move to manual redemptions.

AI-assisted interpretation
The following is analysis, separate from reported facts. Verify important claims independently.
The legacy version CCTP is a protocol version for cross-chain transfers of USDC. Circle is gradually reducing its per-transaction burn limit and overall transfer capacity before pausing the legacy contracts. Applications still connected to the legacy contracts need to migrate to V2, or they will no longer be able to conduct cross-chain transfers via the legacy route.USDC。
Why it matters to readers
Integrations using the legacy CCTP may face capacity restrictions during the period of tightening limits and will no longer be able to transfer USDC through the legacy route after the contracts are paused. Noble chain users should also note its separate redemption window.
If you transfer USDC across chains through a wallet, exchange, or application, you should confirm whether it is still using CCTP V1 and monitor migration or redemption notices.
