Swap Ethereum (ETH Optimism) for Cosmos (ATOM)

The calculator does the maths at the live rate, the page lists the limits and the timing. Your rate is locked the moment the order is created.

The figure is indicative; the exact amount is locked in the order.

One ETH Optimism buys 1,568.82 ATOM right now; the other way round, 1 ATOM is 0.000637423 ETH Optimism. Market over 24 hours: ETH Optimism against ATOM plus 3.25%. The week added plus 9.14%.

The weekly corridor ran from 1,402.62 to 1,547.98 ATOM, a spread of 10.36%. A single order takes 0.012 to 4,400 ETH Optimism. In dollars that is roughly $27.25.

Exchange wallets usually ask for a Memo — copy it from the recipient side before you start. By market cap Ethereum sits 2th ($277.4 B) and Cosmos 82th ($785.9 M). Daily moves of ETH and ATOM over 90 days line up at 0.4 (they travel alike).

Who takes the ETH 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 ETH and ATOM over 90 days line up at 0.4 (they travel alike) — the looser the link, the less a portfolio depends on one coin.
A road both waysThe ATOM → ETH Optimism direction is open too, so going back into ETH takes the same route.

How the ETH Optimism → ATOM order runs

Work out the amount in the calculator: orders start at 0.012 ETH 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 ETH 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.

Swap ETH Optimism for ATOM

Check this before sending ETH 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 0.012 ETH 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: ETH Optimism → ATOM

What rate does ETH Optimism to ATOM run at?

As of Nov 2, 2026 05:34 it is 1 ETH Optimism = 1,568.82 ATOM. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $2,290.47.

What amounts does ETH Optimism → ATOM accept?

From 0.012 to 4,400 ETH Optimism per order. The lower limit is roughly $27.25.

Where does the 0.012 ETH Optimism floor come from?

Network fees and order handling eat a small transfer alive — below 0.012 ETH 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 ETH Optimism, and that one goes to the blockchain, not to us.

How long does ETH 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. A block in Optimism closes in about 12 sec.

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 ETH Optimism to ATOM rate do this month?

The month came in at minus 2.57%. Low 1,203.81, high 1,616.41, middle 1,430.04 ATOM per ETH Optimism.

Can I go back, ATOM to ETH Optimism?

Yes, the reverse direction is open: 1 ATOM = 0.000642549 ETH Optimism. The link sits right under the calculator.
