Swap Cosmos (ATOM) for Ethereum (ETH Optimism)

Q: What rate does ATOM to ETH Optimism run at?

As of Nov 2, 2026 05:59 it is 1 ATOM = 0.000641676 ETH Optimism. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $1.46.

Q: What amounts does ATOM → ETH Optimism accept?

From 50.0309 to 6,850,000 ATOM per order. The lower limit is roughly $73.05.

Q: Where does the 50.0309 ATOM floor come from?

Network fees and order handling eat a small transfer alive — below 50.0309 ATOM the swap stops making sense for either side.

Q: 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 ATOM, and that one goes to the blockchain, not to us.

Q: How long does ATOM to ETH Optimism take?

The clock starts with confirmations: the order goes into work once Cosmos Hub confirms your transfer. After that it comes down to how busy the network is. A block in Cosmos Hub closes in about 6 sec.

Q: Which network will ETH Optimism arrive in?

The payout leaves in Optimism. Make sure the receiving wallet works with that network.

Q: Where is receiving ETH cheaper?

The cheapest is usually ETH Arbitrum, ETH BEP20, ETH Optimism. Still, the network is chosen by what the recipient supports, not by the fee.

Q: 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.

Q: What did the ATOM to ETH Optimism rate do this month?

The month came in at plus 2.64%. Low 0.000618654, high 0.000830693, middle 0.000701936 ETH Optimism per ATOM.

Q: Can I go back, ETH Optimism to ATOM?

Yes, the reverse direction is open: 1 ETH Optimism = 1,570.95 ATOM. The link sits right under the calculator.

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.

Today ATOM goes for 0.000641676 ETH Optimism, and ETH Optimism goes for 1,558.42 ATOM. Market over 24 hours: ATOM against ETH Optimism minus 3.14%. The week added minus 8.38%.

The weekly corridor ran from 0.000646005 to 0.000712953 ETH Optimism, a spread of 10.36%. A single order takes 50.0309 to 6,850,000 ATOM. In dollars that is roughly $73.05.

The payout leaves in the Optimism network, so the receiving address has to belong to that network. By market cap Cosmos sits 82th ($785.9 M) and Ethereum 2th ($277.4 B). Daily moves of ATOM and ETH over 90 days line up at 0.4 (they travel alike).

Who takes the ATOM → ETH Optimism route

Fuel for OptimismWithout Ethereum nothing moves in Optimism — every transfer and every contract call is paid in it.
Different basketsDaily moves of ATOM and ETH 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 ETH Optimism → ATOM direction is open too, so going back into ATOM takes the same route.

Payout network for ETH

The same ETH goes out in several networks. Rates and lower limits differ, and the fee is charged by the network itself.

How the ATOM → ETH Optimism order runs

Work out the amount in the calculator: orders start at 50.0309 ATOM.
Enter a ETH address in Optimism and a way to reach you.
Send ATOM in Cosmos Hub for exactly the amount stated in the order.
Once the network confirms your transfer, Ethereum leaves for your address. The order page tracks every step.

Swap ATOM for ETH Optimism

Check this before sending ATOM

The address network is Optimism. Sending through another network usually means losing the transfer.
The transfer must not be smaller than 50.0309 ATOM.
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.
