Networks and wallets for OP to ATOM
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.
Cosmos Hub mainnet (native ATOM)
Use a Cosmos Hub receive address. If an exchange supplies a memo, enter it exactly as shown so the exchange can identify your deposit.
Check OP deposit and ATOM payout availability separately. The live service needs to accept your source network and offer the destination network that your ATOM wallet expects.
How to convert OP to ATOM
- Enter the OP amount to see the estimated ATOM payout.
- Enter a receiving address on Cosmos Hub mainnet and a refund address on OP Mainnet · ERC-20 OP. Check any destination tag your wallet requires.

How to compare OP to ATOM rates
For a rough pre-fee estimate, multiply the OP amount by the rate expressed in ATOM per OP. Then compare the actual ATOM 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.
