How the ATOM → ARB order runs
- Work out the amount in the calculator and press the exchange button.
- Enter a ARB address in Arbitrum 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, Arbitrum leaves for your address. The order page tracks every step.
Check this before sending ATOM
- The address network is Arbitrum. Sending through another network usually means losing the transfer.
- 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: ATOM → ARB
What rate does ATOM to ARB run at?
As of Nov 2, 2026 03:19 it is 1 ATOM = 8.9325 ARB. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $1.46.
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.
How long does ATOM to ARB 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.
Which network will ARB arrive in?
Arbitrum leaves in its own Arbitrum network — a plain ARB address is all you need.
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 ATOM to ARB rate do this month?
The month came in at plus 5.83%. Low 8.4265, high 11.3089, middle 9.4283 ARB per ATOM.
Can I go back, ARB to ATOM?
