How the ETH Optimism → YFI exchange runs
- Work out the amount in the calculator — orders start at 0.037454 ETH Optimism.
- Give a YFI address on yearn.finance 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 yearn.finance to your address. The order page shows the status.
Check this before sending ETH Optimism
- The address network is yearn.finance. Sending through another network almost always means losing the transfer.
- The transfer must not be smaller than 0.037454 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.

Common questions: ETH Optimism → YFI
What rate does ETH Optimism to YFI run at?
As of Sep 30, 2026 17:20 it is 1 ETH Optimism = 1.0854 YFI. The figure updates on its own, and the calculator always shows the current one. On the market that is around $2,693.78.
What amounts does ETH Optimism → YFI accept?
From 0.037454 to 3,710 ETH Optimism per order. The floor is roughly $100.92.
Why can I not swap less than 0.037454 ETH Optimism?
The network fee and the handling do not depend on the amount. On a transfer below 0.037454 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 YFI 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 YFI arrive in?
yearn.finance arrives in its own yearn.finance network — a plain YFI 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 YFI rate do over the month?
Over the month, minus 0.89%: a low of 1.0736, a high of 1.2078, an average of 1.1268 YFI per 1 ETH Optimism.
Can I swap back, YFI for ETH Optimism?
Yes, the reverse is open too: 1 YFI = 0.921264 ETH Optimism. The link to switch sits under the calculator.
