How the ETHFI → ARB exchange runs
- Work out the amount in the calculator — orders start at 128.5204 ETHFI.
- Give a ARB address on Arbitrum and a contact for the order.
- Send ETHFI on Ether.fi, exactly the amount the order shows.
- Nothing else is needed from you: as soon as the network confirms the transfer, the robot sends Arbitrum to your address. The order page shows the status.
Check this before sending ETHFI
- The address network is Arbitrum. Sending through another network almost always means losing the transfer.
- The transfer must not be smaller than 128.5204 ETHFI.
- 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: ETHFI → ARB
What rate does ETHFI to ARB run at?
As of Sep 30, 2026 19:30 it is 1 ETHFI = 3.7989 ARB. The figure updates on its own, and the calculator always shows the current one. On the market that is around $0.773082.
What amounts does ETHFI → ARB accept?
From 128.5204 to 13,000,000 ETHFI per order. The floor is roughly $99.16.
Why can I not swap less than 128.5204 ETHFI?
The network fee and the handling do not depend on the amount. On a transfer below 128.5204 ETHFI 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 ETHFI, and the blockchain takes that one.
How long does swapping ETHFI for ARB take?
The clock starts with confirmations: as soon as Ether.fi 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 ARB arrive in?
Arbitrum arrives in its own Arbitrum network — a plain ARB 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 ETHFI to ARB rate do over the month?
Over the month, minus 39.19%: a low of 3.0032, a high of 6.2061, an average of 3.9196 ARB per 1 ETHFI.
Can I swap back, ARB for ETHFI?
Yes, the reverse is open too: 1 ARB = 0.263231 ETHFI. The link to switch sits under the calculator.
