How the ARB → OPEN exchange runs
- Work out the amount in the calculator — orders start at 489.402 ARB.
- Give a OPEN address on OpenLedger and a contact for the order.
- Send ARB on Arbitrum, exactly the amount the order shows.
- Nothing else is needed from you: as soon as the network confirms the transfer, the robot sends OpenLedger to your address. The order page shows the status.
Check this before sending ARB
- The address network is OpenLedger. Sending through another network almost always means losing the transfer.
- The transfer must not be smaller than 489.402 ARB.
- 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.

Common questions: ARB → OPEN
What rate does ARB to OPEN run at?
As of Sep 30, 2026 19:15 it is 1 ARB = 1.5794 OPEN. The figure updates on its own, and the calculator always shows the current one. On the market that is around $0.206416.
What amounts does ARB → OPEN accept?
From 489.402 to 48,200,000 ARB per order. The floor is roughly $101.63.
Why can I not swap less than 489.402 ARB?
The network fee and the handling do not depend on the amount. On a transfer below 489.402 ARB they eat a noticeable share of it, and the swap stops making sense for either side.
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 ARB, and the blockchain takes that one.
How long does swapping ARB for OPEN take?
The clock starts with confirmations: as soon as Arbitrum 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.
Which network will OPEN arrive in?
OpenLedger arrives in its own OpenLedger network — a plain OPEN address is all you need.
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.
What did the ARB to OPEN rate do over the month?
Over the month, plus 155.1%: a low of 0.61329, a high of 1.6329, an average of 1.2904 OPEN per 1 ARB.
Can I swap back, OPEN for ARB?
Yes, the reverse is open too: 1 OPEN = 0.63315 ARB. The link to switch sits under the calculator.
