Who takes the ARB → 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 ARB and ATOM over 90 days line up at 0.45 (they travel alike) — the looser the link, the less a portfolio depends on one coin.
- A road both waysThe ATOM → ARB direction is open too, so going back into ARB takes the same route.

How the ARB → ATOM order runs
- Work out the amount in the calculator: orders start at 1,258.65 ARB.
- 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 ARB in Arbitrum 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.
Check this before sending ARB
- 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 1,258.65 ARB.
- 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: ARB → ATOM
What rate does ARB to ATOM run at?
As of Nov 1, 2026 23:59 it is 1 ARB = 0.11239 ATOM. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $0.164089.
What amounts does ARB → ATOM accept?
From 1,258.65 to 61,100,000 ARB per order. The lower limit is roughly $206.06.
Where does the 1,258.65 ARB floor come from?
Network fees and order handling eat a small transfer alive — below 1,258.65 ARB 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 ARB, and that one goes to the blockchain, not to us.
How long does ARB to ATOM take?
The clock starts with confirmations: the order goes into work once Arbitrum confirms your transfer. After that it comes down to how busy the network is.
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 ARB to ATOM rate do this month?
The month came in at minus 5.51%. Low 0.088426, high 0.118673, middle 0.106483 ATOM per ARB.
Can I go back, ATOM to ARB?
Yes, the reverse direction is open: 1 ATOM = 8.9424 ARB. The link sits right under the calculator.
