Swap USDC to USDT

Address and network checks

Both Ethereum and OP Mainnet use EVM-style addresses. An identical address string cannot confirm the network. Check Ethereum in the sending wallet and OP Mainnet in the receiving wallet separately.

Sending USDC

Choose Ethereum mainnet in the wallet. Base, Arbitrum and OP Mainnet use separate balances even when the account address looks identical. 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.

For a standard self-custody transfer on Ethereum, allow for network fees in ETH, separately from your USDC balance. Wallet sponsorship and exchange withdrawal charges can differ; check the sending wallet’s final fee.

Receiving 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. This listed USDT/Optimism 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 USDC on ERC20. The refund is sent in USDC on ERC20; verify that your refund wallet supports this exact asset and network.
