Address and network checks
Both OP Mainnet and Arbitrum One use EVM-style addresses. An identical address string cannot confirm the network. Check OP Mainnet in the sending wallet and Arbitrum One in the receiving wallet separately.
Sending USDT
Select OP Mainnet, often labeled Optimism. Its ETH balance and token balances are separate from those on Ethereum mainnet. Match the USDT network and token supported by the receiving service. A USDT balance on one chain does not automatically appear on another, and a dollar reference does not guarantee the quoted exchange value.
For a standard self-custody transfer on OP Mainnet, allow for network fees in ETH, separately from your USDT balance. Wallet sponsorship and exchange withdrawal charges can differ; check the sending wallet’s final fee.
Receiving USDC
Select Arbitrum One, not Ethereum mainnet or Arbitrum Nova. The receiving service must support this token on Arbitrum One. Confirm the destination supports the exact USDC version returned by the provider. In particular, do not assume USDC, USDC.e and Binance-Peg representations are interchangeable. This listed USDC/Arbitrum option has no separate memo field. If your destination requires additional instructions that this form cannot supply, choose another compatible destination before creating an order.
Refund address for this pair
Enter a refund address that accepts USDT on Optimism. The refund is sent in USDT on Optimism; verify that your refund wallet supports this exact asset and network.
Swap the other direction: USDC to USDT
