ERC20 → Optimism

Swap USDT to USDC

Exchange USDT on Ethereum for USDC on OP Mainnet. Both assets reference USD, but they are separate tokens with different designs and liquidity. A quote can return more or less than one USDC per USDT.

Tether (ERC20) to USDC (Optimism)

You send: Tether (ERC20)USDT · ERC20
You receive: USDC (Optimism)USDC · Optimism

Enter your amount to check live availability for USDT on ERC20 → USDC on Optimism. A provider quote is required before you can create a swap.

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 USDT

Choose Ethereum mainnet in the wallet. Base, Arbitrum and OP Mainnet use separate balances even when the account address looks identical. 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 Ethereum, 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 OP Mainnet, often labeled Optimism. Its ETH balance and token balances are separate from those on Ethereum mainnet. 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/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.

USDC on OP Mainnet

USDC is Circle’s dollar-referenced stablecoin. Native USDC and bridged representations can coexist, so a familiar ticker alone is not enough to identify a deposit asset.

Does a confirmed USDT deposit mean my USDC has arrived?
