About CCTP.io
CCTP.io is an independent interface for moving native USDC through Circle’s Cross-Chain Transfer Protocol. It is not Circle’s official bridge application.
The interface and the protocol
CCTP.io helps you select a route, prepare wallet transactions, and follow a transfer through burn, attestation, and mint. Circle provides the CCTP protocol and attestation service used by those transfers.
Your wallet approves and signs the transactions. CCTP.io cannot rewrite the recipient of a confirmed burn or bypass the protocol’s requirements to mint USDC. Learn the sequence in How CCTP transfers work.
What a transfer depends on
Transfers depend on the source and destination networks, CCTP contracts, Circle’s attestation service, and your wallet. A confirmed source burn still needs a valid attestation and a successful destination mint. Timing estimates are not completion guarantees.
Before signing, check both networks, the native USDC asset, the receiving address, and fees. Keep your source transaction hash so you can find the transfer again. Never give a website or support contact your seed phrase or private key.
Get help
Start with the recovery guide for missing history, pending attestation, and claim problems. If you've tried the recovery guide, then you can reach out over Telegram with your burn transaction hash + source chain and we'll try and help you out.
The application’s public updates are available on X. These are CCTP.io contacts, separate from Circle’s support channels.
