Today ETHFI goes for 0.000249283 ETH Optimism, and ETH Optimism goes for 4,011.5 ETHFI. Market over 24 hours: ETHFI against ETH Optimism plus 1.91%. The week added minus 0.95%.
The weekly corridor ran from 0.000242309 to 0.000304138 ETH Optimism, a spread of 25.52%. A single order takes 337.4388 to 16,600,000 ETHFI. In dollars that is roughly $203.82.
The payout leaves in the Optimism network, so the receiving address has to belong to that network. By market cap Ether.fi sits 96th ($583.53 M) and Ethereum 2th ($298.12 B). Daily moves of ETHFI and ETH over 90 days line up at 0.56 (they travel alike).
Who takes the ETHFI → ETH Optimism route
- Fuel for OptimismWithout Ethereum nothing moves in Optimism — every transfer and every contract call is paid in it.
- Different basketsDaily moves of ETHFI and ETH over 90 days line up at 0.56 (they travel alike) — the looser the link, the less a portfolio depends on one coin.
- A road both waysThe ETH Optimism → ETHFI direction is open too, so going back into ETHFI takes the same route.

How the ETHFI → ETH Optimism order runs
- Work out the amount in the calculator: orders start at 337.4388 ETHFI.
- Enter a ETH address in Optimism and a way to reach you.
- Send ETHFI in Ether.fi for exactly the amount stated in the order.
- Once the network confirms your transfer, Ethereum leaves for your address. The order page tracks every step.
Check this before sending ETHFI
- The address network is Optimism. Sending through another network usually means losing the transfer.
- The transfer must not be smaller than 337.4388 ETHFI.
- Copy the address whole, then compare the first and last characters after pasting.
- Coins go through an AML check: a flagged transfer can be held until the check is finished.

Common questions: ETHFI → ETH Optimism
What rate does ETHFI to ETH Optimism run at?
As of Sep 17, 2026 14:53 it is 1 ETHFI = 0.000249283 ETH Optimism. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $0.608752.
What amounts does ETHFI → ETH Optimism accept?
From 337.4388 to 16,600,000 ETHFI per order. The lower limit is roughly $203.82.
Where does the 337.4388 ETHFI floor come from?
Network fees and order handling eat a small transfer alive — below 337.4388 ETHFI the swap stops making sense for either side.
What else is taken on top of the rate?
The payout is already calculated at the rate in the calculator. On top of it you only pay the network fee for sending ETHFI, and that one goes to the blockchain, not to us.
How long does ETHFI to ETH Optimism take?
The clock starts with confirmations: the order goes into work once Ether.fi confirms your transfer. After that it comes down to how busy the network is.
Which network will ETH Optimism arrive in?
The payout leaves in Optimism. Make sure the receiving wallet works with that network.
Where is receiving ETH cheaper?
The cheapest is usually ETH BEP20, ETH Arbitrum, ETH Optimism. Still, the network is chosen by what the recipient supports, not by the fee.
What if the rate moves while I am paying?
The rate is pinned to the order and does not move while the order is alive. It can be recalculated if the payment arrives late or for a different amount — so send the exact sum, and send it promptly.
What did the ETHFI to ETH Optimism rate do this month?
The month came in at minus 8.92%. Low 0.000216285, high 0.000281667, middle 0.000241708 ETH Optimism per ETHFI.
Can I go back, ETH Optimism to ETHFI?
Yes, the reverse direction is open: 1 ETH Optimism = 4,031.69 ETHFI. The link sits right under the calculator.
