Networks and wallets for OP to ARB
OP Mainnet (ERC-20 OP)
Select OP as the asset and OP Mainnet as the network when the deposit specifies that combination. From self-custody, keep ETH on OP Mainnet to pay for the token transfer.
Arbitrum One (ERC-20 ARB)
Check that the receiving service credits ARB on Arbitrum One specifically. If you plan to send it onward from self-custody, leave some ETH on Arbitrum One for fees.
Check OP deposit and ARB payout availability separately. The live service needs to accept your source network and offer the destination network that your ARB wallet expects.
How to convert OP to ARB
- Enter the OP amount to see the estimated ARB payout.
- Enter a receiving address on Arbitrum One · ERC-20 ARB and a refund address on OP Mainnet · ERC-20 OP. Check any destination tag your wallet requires.
- When the route accepts orders, review the exact amounts and follow the deposit instructions. Submit the OP transaction ID and use your private order link to track the ARB payout.
How to compare OP to ARB rates
For a rough pre-fee estimate, multiply the OP amount by the rate expressed in ARB per OP. Then compare the actual ARB payout for the same OP amount and network. Check whether the withdrawal fee comes out of what you send or is charged separately.
Swap Crypto has a $100 minimum. Estimates use market prices before fees. The order page shows the exact send and receive amounts, and your wallet may charge a separate network fee for sending the deposit.
