base → Optimism

Swap ETH to ETH

Move ETH from Base to OP Mainnet through a provider exchange. Your base balance funds the order and a separate Optimism balance receives it. This is a network change, not a direct wallet transfer; compare the amount returned after the provider’s costs.

Ethereum (Base) to Ethereum (Optimism)

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

Enter your amount to check live availability for ETH 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 ETH

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

For a standard self-custody transfer on Base, allow for network fees in ETH in addition to the amount you send. 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 ETH on base. The refund is sent in ETH on base; verify that your refund wallet supports this exact asset and network.

About this ETH / ETH route

If your destination requires additional instructions that this form cannot supply, choose another compatible destination before creating an order.

Enter your ETH amount to see an approximate receive amount. Click Find the best route to compare providers. Even with the same ticker, network and provider costs can change the amount returned. Floating rates can change before conversion; fixed quotes follow the selected provider’s terms.

Does a confirmed ETH deposit mean my ETH has arrived?

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