Circle CCTPA burn on one chain. A mint on another.

Circle’s Cross-Chain Transfer Protocol moves native USDC between supported blockchains using burn-and-mint. The protocol message and its attestation help explain why a destination mint can occur.

The investigation question

Does the destination mint correspond to this burn?

Keep source and destination chain identifiers, message data and receipts together. Begin with the official protocol documentation to understand which fields establish correspondence.

What this guide does not establish

The current Explore profile is educational. It does not add an automatic CCTP resolver or guarantee destination matching in the workspace.
