Ethereum (ETH BASE) → Ethereum (ETH Arbitrum)

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

As of Sep 30, 2026 21:35 it is 1 ETH BASE = 0.99999 ETH Arbitrum. The figure updates on its own, and the calculator always shows the current one. On the market that is around $2,691.10.

Q: What amounts does ETH BASE → ETH Arbitrum accept?

From 0.0374734 to 3,720 ETH BASE per order. The floor is roughly $100.85.

Q: Why can I not swap less than 0.0374734 ETH BASE?

The network fee and the handling do not depend on the amount. On a transfer below 0.0374734 ETH BASE 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 ETH BASE, and the blockchain takes that one.

Q: How long does swapping ETH BASE for ETH Arbitrum take?

The clock starts with confirmations: as soon as BASE 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. A block in BASE closes in about 12 sec.

Q: Which network will ETH Arbitrum arrive in?

The payout goes out on Arbitrum One. 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 ETH BASE to ETH Arbitrum rate do over the month?

Over the month, about 0%: a low of 1, a high of 1, an average of 1 ETH Arbitrum per 1 ETH BASE.

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

Yes, the reverse is open too: 1 ETH Arbitrum = 0.99999 ETH BASE. 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.

Current maths: 0.99999 ETH Arbitrum for every ETH BASE, and 1 ETH BASE per ETH Arbitrum in reverse. Over 24 hours ETH BASE/ETH Arbitrum came in at about 0%. Over the week, about 0%.

The weekly range ran from 1 to 1 ETH Arbitrum, a spread of 0%. One order takes from 0.0374734 to 3,720 ETH BASE. In dollars that is roughly $100.85.

The robot sends the payout in the Arbitrum One network, so the address has to belong to that network — a transfer to another one will not arrive.

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.
