Arbitrum → Mainnet

Swap ETH to OP

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

Ethereum (Arbitrum One) to Optimism (Mainnet)

You send: Ethereum (Arbitrum One)ETH · Arbitrum
You receive: Optimism (Mainnet)OP · Mainnet

Enter your amount to check live availability for ETH on Arbitrum → OP on Mainnet. A provider quote is required before you can create a swap.

Address and network checks

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

Sending ETH

Select Arbitrum One, not Ethereum mainnet or Arbitrum Nova. The receiving service must support this token on Arbitrum One. 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 Arbitrum One, 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 OP

Choose OP Mainnet using the Mainnet option shown in this directory. Follow the selected provider’s exact deposit instructions before sending. Send the OP token on the network specified by the order. If sending from a normal self-custody wallet on OP Mainnet, allow for gas paid in ETH, not OP. This listed OP/Mainnet 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
