How the ETH Optimism → ETHFI exchange runs
- Work out the amount in the calculator — orders start at 0.0374734 ETH Optimism.
- Give a ETHFI address on Ether.fi and a contact for the order.
- Send ETH Optimism on Optimism, exactly the amount the order shows.
- Nothing else is needed from you: as soon as the network confirms the transfer, the robot sends Ether.fi to your address. The order page shows the status.
Check this before sending ETH Optimism
- The address network is Ether.fi. Sending through another network almost always means losing the transfer.
- The transfer must not be smaller than 0.0374734 ETH Optimism.
- 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.

Why people take the ETH Optimism → ETHFI route
- A DeFi protocol tokenEther.fi belongs to decentralised finance: holders govern the protocol with it and pay for operations inside it.
- Different basketsDaily moves of ETH and ETHFI over 90 days link at 0.56 (they travel alike) — the weaker the link, the less a portfolio rests on one coin.
- It works both waysThe ETHFI → ETH Optimism direction is open as well — going back into ETH takes the same route and the same automation.
Common questions: ETH Optimism → ETHFI
What rate does ETH Optimism to ETHFI run at?
As of Oct 1, 2026 00:35 it is 1 ETH Optimism = 3,439.49 ETHFI. The figure updates on its own, and the calculator always shows the current one. On the market that is around $2,655.87.
What amounts does ETH Optimism → ETHFI accept?
From 0.0374734 to 3,740 ETH Optimism per order. The floor is roughly $100.10.
Why can I not swap less than 0.0374734 ETH Optimism?
The network fee and the handling do not depend on the amount. On a transfer below 0.0374734 ETH Optimism 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 ETH Optimism, and the blockchain takes that one.
How long does swapping ETH Optimism for ETHFI take?
The clock starts with confirmations: as soon as Optimism 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 Optimism closes in about 12 sec.
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 ETH Optimism to ETHFI rate do over the month?
Over the month, minus 24.06%: a low of 3,503.58, a high of 4,623.53, an average of 3,974.77 ETHFI per 1 ETH Optimism.
Can I swap back, ETHFI for ETH Optimism?
Yes, the reverse is open too: 1 ETHFI = 0.000290735 ETH Optimism. The link to switch sits under the calculator.
