Arbitrum (ARB) → Ethereum (ETH BASE)

Q: What rate does ARB to ETH BASE run at?

As of Sep 30, 2026 20:55 it is 1 ARB = 0.0000761421 ETH BASE. The figure updates on its own, and the calculator always shows the current one. On the market that is around $0.203503.

Q: What amounts does ARB → ETH BASE accept?

From 489.402 to 49,500,000 ARB per order. The floor is roughly $98.87.

Q: 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.

Q: 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.

Q: How long does swapping ARB for ETH BASE 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.

Q: Which network will ETH BASE arrive in?

The payout goes out on BASE. Check that the receiving wallet supports that network.

Q: Which network is cheaper for receiving ETH?

Usually ETH BEP20, ETH Arbitrum, ETH Optimism works out cheaper. Still, the network is picked by what the recipient accepts, not by the fee.

Q: 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.

Q: What did the ARB to ETH BASE rate do over the month?

Over the month, plus 116.56%: a low of 0.0000348501, a high of 0.0000853551, an average of 0.0000672124 ETH BASE per 1 ARB.

Q: Can I swap back, ETH BASE for ARB?

Yes, the reverse is open too: 1 ETH BASE = 13,133.07 ARB. The link to switch sits under the calculator.

The order runs on autopilot: the rate is locked when you create it, and the payout leaves as soon as the network confirms your transfer. No manual approval, no working hours.

Preliminary figure: the final amount is locked in the order.

Right now 1 ARB gets you 0.0000761421 ETH BASE; the other way round, 1 ETH BASE is 13,133.33 ARB. Over 24 hours ARB/ETH BASE came in at minus 1.51%. Over the week, minus 9.27%.

The weekly range ran from 0.000073216 to 0.0000850186 ETH BASE, a spread of 16.12%. One order takes from 489.402 to 49,500,000 ARB. In dollars that is roughly $98.87.

The robot sends the payout in the BASE network, so the address has to belong to that network — a transfer to another one will not arrive. Market capitalisation puts Arbitrum at No. 68 ($1.37 B) and Ethereum at No. 2 ($326.45 B). Over 90 days the daily moves of ARB and ETH correlate at 0.64 (they travel alike).

Which network ETH arrives in

The same ETH goes out in several networks. Each has its own rate and its own floor, and the fee is charged by the network itself.

How the ARB → ETH BASE exchange runs

Work out the amount in the calculator — orders start at 489.402 ARB.
Give a ETH address on BASE 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 Ethereum to your address. The order page shows the status.

Swap ARB for ETH BASE

Check this before sending ARB

The address network is BASE. 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.
