Check a CCTP route before the October 31 V1 phase-out begins

Check a CCTP route before the October 31 V1 phase-out begins

Circle says CCTP V1 deprecation begins on October 31, 2026 and completes on December 1, with legacy burn limits reduced during the window. A user should not guess which version an application uses from a generic bridge label.

Circle's August 27 notice addresses developers and describes the planned V1-to-V2 migration timeline. Application interfaces, supported chains and receiver policies still need current verification.

Identify whether CCTP is involved

Record the application, source chain, destination chain, asset and named transfer protocol. A cross-chain USDC interface may use liquidity, wrapped assets or another bridge instead of CCTP.

Do not infer protocol from the token symbol. The notice supports the stated dates, the separate V2 contracts and APIs, and the warning that V1 integrations must migrate rather than assume backward compatibility.

Compare the application's documented contracts and APIs with Circle's current migration material. CCTP V2 is not a cosmetic rename of every V1 integration. Treat an unlabeled route as unresolved.

Distinguish V1 and V2 evidence

Compare the application's documented contracts and APIs with Circle's current migration material. CCTP V2 is not a cosmetic rename of every V1 integration.

Treat an unlabeled route as unresolved. It cannot prove SignalBet or a wallet uses CCTP, guarantee a transfer, identify an application's contracts from its branding, recover a failed burn or approve a destination chain.

Note that Circle describes deprecation beginning October 31 and contract pause completion on December 1, 2026. A phased reduction is not the same as an instant universal shutdown. Check for later Circle updates before acting.

Apply the timeline precisely

Note that Circle describes deprecation beginning October 31 and contract pause completion on December 1, 2026. A phased reduction is not the same as an instant universal shutdown.

Check for later Circle updates before acting. Ask the application to identify its CCTP version and documented contracts, confirm both chains and the receiver route, and avoid starting a legacy transfer whose support is unclear.

Verify that the final chain and native USDC route are accepted by the authenticated receiving account. Protocol-level completion does not force a private receiver to credit the asset. Save the deposit instruction before transfer.

Check receiver compatibility

Verify that the final chain and native USDC route are accepted by the authenticated receiving account. Protocol-level completion does not force a private receiver to credit the asset.

Save the deposit instruction before transfer. Never use a cross-chain migration deadline to justify a rushed gambling deposit. Pause until the application and receiving account both document the route.

Keep source burn, message or attestation, destination transaction and receiver ledger as separate records. One spinner can conceal several independently failing stages. Escalate the exact boundary without repeating the transfer.

What the official source supports

Circle CCTP V1 legacy deprecation notice: The notice supports the stated dates, the separate V2 contracts and APIs, and the warning that V1 integrations must migrate rather than assume backward compatibility.

Where the source stops

It cannot prove SignalBet or a wallet uses CCTP, guarantee a transfer, identify an application's contracts from its branding, recover a failed burn or approve a destination chain.

Make the documented decision

Ask the application to identify its CCTP version and documented contracts, confirm both chains and the receiver route, and avoid starting a legacy transfer whose support is unclear.

Never use a cross-chain migration deadline to justify a rushed gambling deposit. Pause until the application and receiving account both document the route.

Run a final evidence review before acting

Circle's August 27 notice addresses developers and describes the planned V1-to-V2 migration timeline. Application interfaces, supported chains and receiver policies still need current verification. Review these checkpoints in order: Identify whether CCTP is involved; Distinguish V1 and V2 evidence; Apply the timeline precisely; Check receiver compatibility; Preserve stage-specific evidence. Leave an unanswered item visibly unresolved instead of replacing it with a guess. It cannot prove SignalBet or a wallet uses CCTP, guarantee a transfer, identify an application's contracts from its branding, recover a failed burn or approve a destination chain.
