Transfer USDC

Initiate a transfer

To get started with CCTP, call depositForBurn (opens in a new tab) from any of the following contracts:

Chain	Domain	Contract address
Ethereum	0	0x598e338581e69BE32BCead94F1476FF301b8b0DF
Avalanche	1	0x598e338581e69BE32BCead94F1476FF301b8b0DF
Optimism	2	0x598e338581e69BE32BCead94F1476FF301b8b0DF
Arbitrum	3	0x598e338581e69BE32BCead94F1476FF301b8b0DF
Noble	4	N/A
Base	6	0x598e338581e69BE32BCead94F1476FF301b8b0DF
Polygon	7	0x598e338581e69BE32BCead94F1476FF301b8b0DF

Once the transfer is initiated, our relayer network will listen for burns and automatically mint them on the destination chain.

Track a transfer

For convenience, bridges can be tracked via our trace api.

Example: https://cctp.money/api/trace?txHash=27F8C932754EBB2128F0BAAC8FE22029F25E2AE9D690989CF095AC416720FB97&sourceDomain=4 (opens in a new tab)

Manually mint

While rare, a transfer can get stuck in the ATTESTATION_FOUND state and fail to mint due to variable chain and network conditions.

To manually mint, simply call receiveMessage on the destination chain with the msg_sent_bytes and attestation from the API response.
