How OP to ATOM is routed right now

You pay your wallet's own network fee to send OP on OP Mainnet. The network fee for paying out ATOM on Cosmos Hub is already included in the rate.
OP to ATOM at a glance
Optimism and Cosmos live on different blockchains, and this swap uses the native assets on both, with no bridge contract and no wrapped token. The exchange receives OP on OP Mainnet and pays out ATOM on Cosmos Hub.
Your ATOM is paid on Cosmos Hub. Use an address that starts with cosmos1. If your wallet or exchange gave you a memo, enter it as well; for a personal wallet it can usually be left empty.

OP to ATOM: questions and answers
How do I swap OP to ATOM without KYC?
Enter the OP amount on this page, paste your ATOM address and send your OP to the deposit address shown. AltoSwap has no accounts and asks for no identity documents, and it routes your swap through exchanges rated A for KYC, meaning providers that do not run identity checks. The ATOM is paid directly to your wallet.
What is the OP to ATOM exchange rate?
The rate moves with the market every few seconds and depends on the amount. The calculator at the top of this page requests live quotes from 20+ exchanges and shows the best current OP to ATOM rate for the amount you enter.
What are the minimum and maximum for OP to ATOM?
The minimum is about 16.1 OP and the maximum about 5,027,177 OP. Limits vary slightly between exchanges and follow market prices; the form tells you immediately if your amount is outside the range.
How long does a OP to ATOM swap take?
Usually 5 to 30 minutes. Most of that is waiting for your OP deposit to confirm on OP Mainnet, which takes about a minute. There is no verification step, so nothing else adds to the wait.
Is swapping OP to ATOM anonymous?
AltoSwap does not know who you are (no account, no email, no identity checks) and the default route uses no-KYC exchanges. Both OP Mainnet and Cosmos Hub are public ledgers, though, so the transactions themselves are visible on-chain. For on-chain privacy, swap into a privacy coin such as Monero.
Which ATOM address should I use?
Your ATOM is paid on Cosmos Hub. Use an address that starts with cosmos1. If your wallet or exchange gave you a memo, enter it as well; for a personal wallet it can usually be left empty. Always use an address in a wallet you control and double-check the first and last characters before sending.
What fees are included in the OP to ATOM rate?
Everything. The exchange's spread, the Cosmos Hub network fee for the payout and any service commission are already inside the quoted rate, so the amount shown is what you receive: exactly on a fixed rate, approximately on a floating rate. You only pay your own OP Mainnet network fee to send the deposit.
Can I swap ATOM back to OP?
Yes. The reverse direction, ATOM to OP, works the same way and has its own page and live rate on AltoSwap. Each direction is quoted independently, so the two rates are not exact mirrors of each other.
