Swap USDC to ETH

Exchange USDC from Base into ETH on OP Mainnet. The provider waits for the USDC deposit before arranging the ETH payout on the destination network. Track those as separate transactions rather than using a sending-chain confirmation as proof of receipt.

USDC (Base) to Ethereum (Optimism)

You send: USDC (Base)USDC · base
You receive: Ethereum (Optimism)ETH · Optimism

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

Address and network checks

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

Sending USDC

Switch the wallet to Base. ETH on Ethereum mainnet cannot pay the normal gas fee for a separate token transfer on Base. 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 Base, 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 ETH

Select OP Mainnet, often labeled Optimism. Its ETH balance and token balances are separate from those on Ethereum mainnet. Native ETH and wrapped Ether (WETH) are different assets. Use the ETH balance on the selected network; do not substitute WETH for an ETH deposit. This listed ETH/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 base. The refund is sent in USDC on base; verify that your refund wallet supports this exact asset and network.

SENDING ASSET

USDC on Base

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.

RECEIVING ASSET

Ethereum on OP Mainnet

Ether is used for transaction fees and staking on Ethereum. ETH is also available on several separate networks in this directory, so the network is part of the asset you select.

Does a confirmed USDC deposit mean my ETH has arrived?
