ERC20 → Optimism

Swap EURC to USDT

Exchange EURC on Ethereum for USDT on OP Mainnet. EURC references EUR while USDT references USD. Currency conversion is part of this quote, so a one-to-one output is not the expected baseline.

Euro Coin (ERC20) to Tether (Optimism)

You send: Euro Coin (ERC20)EURC · ERC20
You receive: Tether (Optimism)USDT · Optimism

Enter your amount to check live availability for EURC on ERC20 → USDT 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 EURC

Choose Ethereum mainnet in the wallet. Base, Arbitrum and OP Mainnet use separate balances even when the account address looks identical. A EURC-to-dollar-stablecoin quote reflects two different reference currencies as well as provider pricing. Do not assume that one EURC should return one unit of a USD stablecoin.

For a standard self-custody transfer on Ethereum, allow for network fees in ETH, separately from your EURC 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 EURC on ERC20. The refund is sent in EURC on ERC20; verify that your refund wallet supports this exact asset and network.

How much USDT will I get for EURC?

Enter your EURC amount to see an approximate receive amount. Click Find the best route to compare providers. This is a EUR-referenced to USD-referenced token exchange, so currency conversion also affects the ratio. Floating rates can change before conversion; fixed quotes follow the selected provider’s terms.

Does a confirmed EURC deposit mean my USDT has arrived?

No. Deposit confirmation on Ethereum, provider processing and payout on OP Mainnet are separate steps. Use Track swap to see the order status, then check the USDT balance on the receiving network. A live quote or historical route check does not guarantee completion time.
