Cosmos (ATOM) → Ethereum (ETH Arbitrum)

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

As of Sep 30, 2026 16:05 it is 1 ATOM = 0.000635763 ETH Arbitrum. The figure updates on its own, and the calculator always shows the current one. On the market that is around $1.71.

Q: What amounts does ATOM → ETH Arbitrum accept?

From 58.2851 to 5,810,000 ATOM per order. The floor is roughly $100.25.

Q: Why can I not swap less than 58.2851 ATOM?

The network fee and the handling do not depend on the amount. On a transfer below 58.2851 ATOM they eat a noticeable share of it, and the swap stops making sense for either side.

Q: 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 ATOM, and the blockchain takes that one.

Q: How long does swapping ATOM for ETH Arbitrum take?

The clock starts with confirmations: as soon as Cosmos Hub 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 Cosmos Hub closes in about 6 sec.

Q: Which network will ETH Arbitrum arrive in?

The payout goes out on Arbitrum One. Check that the receiving wallet supports that network.

Q: Which network is cheaper for receiving ETH?

Usually ETH BEP20, ETH Arbitrum, ETH Optimism works out cheaper. Still, the network is picked by what the recipient accepts, not by the fee.

Q: 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.

Q: What did the ATOM to ETH Arbitrum rate do over the month?

Over the month, plus 5.32%: a low of 0.000595746, a high of 0.000752165, an average of 0.000650037 ETH Arbitrum per 1 ATOM.

Q: Can I swap back, ETH Arbitrum for ATOM?

Yes, the reverse is open too: 1 ETH Arbitrum = 1,572.88 ATOM. The link to switch sits under the calculator.

The order runs on autopilot: the rate is locked when you create it, and the payout leaves as soon as the network confirms your transfer. No manual approval, no working hours.

Preliminary figure: the final amount is locked in the order.

Right now 1 ATOM gets you 0.000635763 ETH Arbitrum; the other way round, 1 ETH Arbitrum is 1,572.91 ATOM. Over 24 hours ATOM/ETH Arbitrum came in at minus 2.23%. Over the week, minus 2.65%.

The weekly range ran from 0.000627241 to 0.000701636 ETH Arbitrum, a spread of 11.86%. One order takes from 58.2851 to 5,810,000 ATOM. In dollars that is roughly $100.25.

The robot sends the payout in the Arbitrum One network, so the address has to belong to that network — a transfer to another one will not arrive. Market capitalisation puts Cosmos at No. 83 ($916.95 M) and Ethereum at No. 2 ($328.92 B). Over 90 days the daily moves of ATOM and ETH correlate at 0.45 (they travel alike).

Which network ETH arrives in

The same ETH goes out in several networks. Each has its own rate and its own floor, and the fee is charged by the network itself.

How the ATOM → ETH Arbitrum exchange runs

Work out the amount in the calculator — orders start at 58.2851 ATOM.
Give a ETH address on Arbitrum One and a contact for the order.
Send ATOM on Cosmos Hub, exactly the amount the order shows.
Nothing else is needed from you: as soon as the network confirms the transfer, the robot sends Ethereum to your address. The order page shows the status.

Swap ATOM for ETH Arbitrum

Check this before sending ATOM

The address network is Arbitrum One. Sending through another network almost always means losing the transfer.
The transfer must not be smaller than 58.2851 ATOM.
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 ATOM → ETH Arbitrum route

Fuel for Arbitrum OneWithout Ethereum you cannot pay for a transfer or a contract call in Arbitrum One — the coin is needed for anything that happens in that ecosystem.
Different basketsDaily moves of ATOM and ETH 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 ETH Arbitrum → ATOM direction is open as well — going back into ATOM takes the same route and the same automation.
