Circle's Cross-Chain Transfer Protocol (CCTP) enables native, burn-and-mint USDC transfers across chains, with optional gateway-based unified balances, reducing bridge risk and improving finality.
Integrate a sender on the source chain and a receiver on the destination, then monitor attestations and complete the mint.

To transfer USDC across chains using Circle's CCTP, you burn tokens on the source chain via TokenMessenger, wait for the burn attestation, and mint USDC on the destination chain using MessageTransmitter.
The CCTP workflow for cross-chain USDC involves destroying tokens at the source, generating a cryptographic attestation of that burn, and relaying it to the destination chain to unlock and mint the equivalent USDC supply.
Yes, CCTP V2 supports post-mint logic execution on the destination chain by allowing developers to attach optional hook data to the transfer message, triggering custom Solidity functions immediately after the USDC mint.
Yes, you can use CCTP to bridge USDC across supported networks including Ethereum, Base, Arbitrum, Optimism, and Polygon by configuring the correct domain IDs and per-chain contract addresses for the transfer.
To format recipient addresses for CCTP cross-chain USDC transfers, you must encode the standard 20-byte Ethereum address into a left-padded bytes32 format before passing it to the TokenMessenger contract.
The best way to achieve near-instant cross-chain USDC transfers is by utilizing the optional CCTP V2 Gateway integration, which provides unified balances and faster finality across supported domains.
