The direction runs at 0.0651575 ATOM per OP Optimism, or 15.3474 OP Optimism per ATOM. Market over 24 hours: OP Optimism against ATOM plus 3.24%. The week added plus 20.16%.
The weekly corridor ran from 0.052661 to 0.065633 ATOM, a spread of 24.63%. A single order takes 2,157.5 to 101,000,000 OP Optimism. In dollars that is roughly $213.48.
Exchange wallets usually ask for a Memo — copy it from the recipient side before you start. By market cap Optimism sits 165th ($227.48 M) and Cosmos 81th ($819.45 M). Daily moves of OP and ATOM over 90 days line up at 0.17 (they travel apart).
Who takes the OP Optimism → ATOM route
- Fuel for Cosmos HubWithout Cosmos nothing moves in Cosmos Hub — every transfer and every contract call is paid in it.
- Different basketsDaily moves of OP and ATOM over 90 days line up at 0.17 (they travel apart) — the looser the link, the less a portfolio depends on one coin.
- A road both waysThe ATOM → OP Optimism direction is open too, so going back into OP takes the same route.

How the OP Optimism → ATOM order runs
- Work out the amount in the calculator: orders start at 2,157.5 OP Optimism.
- Enter a ATOM address in Cosmos Hub and a way to reach you. Receiving to an exchange? Add the Memo, or the payment will hang.
- Send OP Optimism in Optimism for exactly the amount stated in the order.
- Once the network confirms your transfer, Cosmos leaves for your address. The order page tracks every step.
Check this before sending OP Optimism
- The address network is Cosmos Hub. Sending through another network usually means losing the transfer.
- If the receiving wallet asks for a Memo, put it in the order.
- The transfer must not be smaller than 2,157.5 OP Optimism.
- Copy the address whole, then compare the first and last characters after pasting.
- Coins go through an AML check: a flagged transfer can be held until the check is finished.

Common questions: OP Optimism → ATOM
What rate does OP Optimism to ATOM run at?
As of Sep 17, 2026 20:33 it is 1 OP Optimism = 0.0651575 ATOM. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $0.100343.
What amounts does OP Optimism → ATOM accept?
From 2,157.5 to 101,000,000 OP Optimism per order. The lower limit is roughly $213.48.
Where does the 2,157.5 OP Optimism floor come from?
Network fees and order handling eat a small transfer alive — below 2,157.5 OP Optimism the swap stops making sense for either side.
What else is taken on top of the rate?
The payout is already calculated at the rate in the calculator. On top of it you only pay the network fee for sending OP Optimism, and that one goes to the blockchain, not to us.
How long does OP Optimism to ATOM take?
The clock starts with confirmations: the order goes into work once Optimism confirms your transfer. After that it comes down to how busy the network is.
Which network will ATOM arrive in?
Cosmos leaves in its own Cosmos Hub network — a plain ATOM address is all you need. Some exchanges and wallets also need a Memo.
What if the rate moves while I am paying?
The rate is pinned to the order and does not move while the order is alive. It can be recalculated if the payment arrives late or for a different amount — so send the exact sum, and send it promptly.
What did the OP Optimism to ATOM rate do this month?
The month came in at plus 5.36%. Low 0.0523876, high 0.0707025, middle 0.0631652 ATOM per OP Optimism.
Can I go back, ATOM to OP Optimism?
Yes, the reverse direction is open: 1 ATOM = 15.4247 OP Optimism. The link sits right under the calculator.
