Common questions: ARB → ETHFI

What rate does ARB to ETHFI run at?

As of Sep 30, 2026 19:30 it is 1 ARB = 0.263231 ETHFI. The figure updates on its own, and the calculator always shows the current one. On the market that is around $0.203104.

What amounts does ARB → ETHFI accept?

From 489.402 to 49,100,000 ARB per order. The floor is roughly $99.59.

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 ETHFI 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 ETHFI arrive in?

Ether.fi arrives in its own Ether.fi network — a plain ETHFI 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 ETHFI rate do over the month?

Over the month, plus 64.46%: a low of 0.161131, a high of 0.332982, an average of 0.264905 ETHFI per 1 ARB.

Can I swap back, ETHFI for ARB?

Yes, the reverse is open too: 1 ETHFI = 3.7989 ARB. The link to switch sits under the calculator.
