Do not confuse a complete CCTP attestation with recipient credit
A cross-chain state map for burn evidence, message hash, attestation response, destination mint transaction and the receiver's separate account ledger.
Do not confuse a complete CCTP attestation with recipient credit
A CCTP attestation confirms a signed message associated with a source-chain burn, but it is not the same as destination execution or credit inside a private account. A useful incident record follows every state without skipping the mint and receiver ledger.
Circle's API reference describes retrieving an attestation by message hash and shows response states. Route versions, finality rules and application behavior require their own current documentation.
Record the source-chain burn
Capture the source network, burn transaction, amount, token contract and finality state from a reputable explorer. A wallet completion label may appear before the event has the route's required finality.
Keep the transaction hash and event index while excluding private keys. The reference supports using the message hash as the lookup key and recognizing that an attestation response is one defined step in a larger transfer.
Use the route's documented message bytes and hashing method, then compare the lookup key across tools. A transaction hash and CCTP message hash are different identifiers. Document which application produced the message bytes and version.
Derive and verify the message hash
Use the route's documented message bytes and hashing method, then compare the lookup key across tools. A transaction hash and CCTP message hash are different identifiers.
Document which application produced the message bytes and version. It cannot prove destination execution, authenticate a receiver, guarantee account credit, reverse a burn or resolve a route built by another application.
Read the status and signed attestation without translating complete into minted or credited. The API can return one workflow milestone while destination submission remains outstanding. Save the observation time and endpoint environment so sandbox and production are not mixed.
Interpret the attestation response
Read the status and signed attestation without translating complete into minted or credited. The API can return one workflow milestone while destination submission remains outstanding.
Save the observation time and endpoint environment so sandbox and production are not mixed. Call the route complete only when the source event, attestation, destination mint and receiving-account record all reconcile to the same transfer.
Locate the destination transaction that consumes the message and verify its receipt, token amount and beneficiary. An attestation that is never submitted cannot update the destination chain. Distinguish a failed destination call from an application that has not attempted it.
Find the destination execution
Locate the destination transaction that consumes the message and verify its receipt, token amount and beneficiary. An attestation that is never submitted cannot update the destination chain.
Distinguish a failed destination call from an application that has not attempted it. Cross-chain delay should pause further gambling transfers. Keep essential funds outside the route and do not pay an unsolicited recovery service.
Provide the complete cross-chain identifiers and ask whether the account is unseen, processing, held or credited. A successful mint to an address does not itself attach the transfer to a private user account. Close the case with both destination-chain and receiver-ledger evidence.
Ask the receiver about its ledger
Provide the complete cross-chain identifiers and ask whether the account is unseen, processing, held or credited. A successful mint to an address does not itself attach the transfer to a private user account.

What the official source supports
Circle CCTP attestation API reference: The reference supports using the message hash as the lookup key and recognizing that an attestation response is one defined step in a larger transfer.
Where the source stops
It cannot prove destination execution, authenticate a receiver, guarantee account credit, reverse a burn or resolve a route built by another application.
Make the documented decision
Call the route complete only when the source event, attestation, destination mint and receiving-account record all reconcile to the same transfer.
Cross-chain delay should pause further gambling transfers. Keep essential funds outside the route and do not pay an unsolicited recovery service.
