- Different basketsDaily moves of OPEN and ATOM over 90 days line up at 0.37 (they travel apart) — the looser the link, the less a portfolio depends on one coin.
- A road both waysThe ATOM → OPEN direction is open too, so going back into OPEN takes the same route.

How the OPEN → ATOM order runs
- Work out the amount in the calculator: orders start at 1,502.63 OPEN.
- 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 OPEN in OpenLedger 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 OPEN
- 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 1,502.63 OPEN.
- 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: OPEN → ATOM
What rate does OPEN to ATOM run at?
As of Sep 17, 2026 16:38 it is 1 OPEN = 0.0888097 ATOM. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $0.135879.
What amounts does OPEN → ATOM accept?
From 1,502.63 to 73,700,000 OPEN per order. The lower limit is roughly $204.01.
Where does the 1,502.63 OPEN floor come from?
Network fees and order handling eat a small transfer alive — below 1,502.63 OPEN 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 OPEN, and that one goes to the blockchain, not to us.
How long does OPEN to ATOM take?
The clock starts with confirmations: the order goes into work once OpenLedger 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 OPEN to ATOM rate do this month?
The month came in at minus 23.68%. Low 0.0672764, high 0.117165, middle 0.0916621 ATOM per OPEN.
Can I go back, ATOM to OPEN?
Yes, the reverse direction is open: 1 ATOM = 11.3167 OPEN. The link sits right under the calculator.
