Common questions: USDT Arbitrum → ETHFI

What rate does USDT Arbitrum to ETHFI run at?
As of Sep 30, 2026 17:45 it is 1 USDT Arbitrum = 1.2852 ETHFI. The figure updates on its own, and the calculator always shows the current one. On the market that is around $0.983891.
What amounts does USDT Arbitrum → ETHFI accept?
From 100.67 to 10,000,000 USDT Arbitrum per order. The floor is roughly $100.63.
Why can I not swap less than 100.67 USDT Arbitrum?
The network fee and the handling do not depend on the amount. On a transfer below 100.67 USDT Arbitrum they eat a noticeable share of it, and the swap stops making sense for either side.
Is anything charged on top of the rate?

The clock starts with confirmations: as soon as Arbitrum One 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.
