Right now 1 ETH Optimism gets you 1,554.12 ATOM; the other way round, 1 ATOM is 0.000643452 ETH Optimism. Over 24 hours ETH Optimism/ATOM came in at plus 0.39%. Over the week, plus 2.99%.
The weekly range ran from 1,423.48 to 1,591.14 ATOM, a spread of 11.78%. One order takes from 0.0374734 to 3,740 ETH Optimism. In dollars that is roughly $100.15.
If the recipient is an exchange, it usually needs a Memo: take it from your account beforehand and the automation will attach it to the transfer. Market capitalisation puts Ethereum at No. 2 ($326.31 B) and Cosmos at No. 83 ($916.5 M). Over 90 days the daily moves of ETH and ATOM correlate at 0.45 (they travel alike).

How the ETH Optimism → ATOM exchange runs
- Work out the amount in the calculator — orders start at 0.0374734 ETH Optimism.
- Give a ATOM address on Cosmos Hub and a contact for the order. Receiving to an exchange? Add the Memo, or the payment will hang on the recipient side.
- Send ETH Optimism on Optimism, exactly the amount the order shows.
- Nothing else is needed from you: as soon as the network confirms the transfer, the robot sends Cosmos to your address. The order page shows the status.
Check this before sending ETH Optimism
- The address network is Cosmos Hub. Sending through another network almost always means losing the transfer.
- If the recipient asks for a Memo, enter it when you create the order.
- The transfer must not be smaller than 0.0374734 ETH Optimism.
- Copy the address in full, then check its first and last characters once it is pasted.
- Send exactly the amount stated in the order: the automation matches your payment against it, and any difference sends the order back for recalculation.

Why people take the ETH Optimism → ATOM route
- Fuel for Cosmos HubWithout Cosmos you cannot pay for a transfer or a contract call in Cosmos Hub — the coin is needed for anything that happens in that ecosystem.
- Different basketsDaily moves of ETH and ATOM over 90 days link at 0.45 (they travel alike) — the weaker the link, the less a portfolio rests on one coin.
- It works both waysThe ATOM → ETH Optimism direction is open as well — going back into ETH takes the same route and the same automation.
Common questions: ETH Optimism → ATOM
What rate does ETH Optimism to ATOM run at?
As of Sep 30, 2026 11:05 it is 1 ETH Optimism = 1,554.12 ATOM. The figure updates on its own, and the calculator always shows the current one. On the market that is around $2,673.08.
What amounts does ETH Optimism → ATOM accept?
From 0.0374734 to 3,740 ETH Optimism per order. The floor is roughly $100.15.
Why can I not swap less than 0.0374734 ETH Optimism?
The network fee and the handling do not depend on the amount. On a transfer below 0.0374734 ETH Optimism they eat a noticeable share of it, and the swap stops making sense for either side.
Is anything charged on top of the rate?
No. The payout is already worked out at the rate in the calculator. Separately you pay only the network fee for sending ETH Optimism, and the blockchain takes that one.
How long does swapping ETH Optimism for ATOM take?
The clock starts with confirmations: as soon as Optimism confirms your transfer, the order goes out for payout with no operator involved. After that the timing is set by how busy the network is — which is the difference between quick and instant. A block in Optimism closes in about 12 sec.
Which network will ATOM arrive in?
Cosmos arrives in its own Cosmos Hub network — a plain ATOM address is all you need. Some exchanges and wallets also need a Memo.
What happens if the rate moves while I am paying?
Nothing: the rate is locked in the order and holds for as long as the order is alive. It is recalculated only if the payment arrives late or for a different amount — so send the exact sum, and send it promptly.
What did the ETH Optimism to ATOM rate do over the month?
Over the month, minus 5.39%: a low of 1,329.49, a high of 1,678.57, an average of 1,543.77 ATOM per 1 ETH Optimism.
Can I swap back, ATOM for ETH Optimism?
Yes, the reverse is open too: 1 ATOM = 0.000643439 ETH Optimism. The link to switch sits under the calculator.
