Swap Cosmos (ATOM) for Ethereum (ETH Arbitrum)

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

As of Nov 2, 2026 01:04 it is 1 ATOM = 0.000649162 ETH Arbitrum. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $1.47.

Q: What amounts does ATOM → ETH Arbitrum 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 Arbitrum 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 Arbitrum arrive in?

The payout leaves in Arbitrum One. 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 Arbitrum rate do this month?

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

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

Yes, the reverse direction is open: 1 ETH Arbitrum = 1,552.84 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.

One ATOM buys 0.000649162 ETH Arbitrum right now; the other way round, 1 ETH Arbitrum is 1,540.45 ATOM. Market over 24 hours: ATOM against ETH Arbitrum minus 3.15%. The week added minus 7.72%.

The weekly corridor ran from 0.000646503 to 0.000712953 ETH Arbitrum, a spread of 10.28%. A single order takes 50.0309 to 6,850,000 ATOM. In dollars that is roughly $73.05.

The payout leaves in the Arbitrum One network, so the receiving address has to belong to that network. By market cap Cosmos sits 83th ($788.07 M) and Ethereum 2th ($276.28 B). Daily moves of ATOM and ETH over 90 days line up at 0.4 (they travel alike).

Who takes the ATOM → ETH Arbitrum route

Fuel for Arbitrum OneWithout Ethereum nothing moves in Arbitrum One — 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 Arbitrum → ATOM direction is open too, so going back into ATOM takes the same route.

How the ATOM → ETH Arbitrum order runs

Work out the amount in the calculator: orders start at 50.0309 ATOM.
Enter a ETH address in Arbitrum One 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 Arbitrum

Check this before sending ATOM

The address network is Arbitrum One. 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.
