yearn.finance (YFI) → Ethereum (ETH Optimism)

Q: What rate does YFI to ETH Optimism run at?

As of Sep 30, 2026 17:20 it is 1 YFI = 0.921264 ETH Optimism. The figure updates on its own, and the calculator always shows the current one. On the market that is around $2,482.36.

Q: What amounts does YFI → ETH Optimism accept?

From 0.0417853 to 4,030 YFI per order. The floor is roughly $103.70.

Q: Why can I not swap less than 0.0417853 YFI?

The network fee and the handling do not depend on the amount. On a transfer below 0.0417853 YFI they eat a noticeable share of it, and the swap stops making sense for either side.

Q: 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 YFI, and the blockchain takes that one.

Q: How long does swapping YFI for ETH Optimism take?

The clock starts with confirmations: as soon as yearn.finance 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.

Q: Which network will ETH Optimism arrive in?

The payout goes out on Optimism. Check that the receiving wallet supports that network.

Q: Which network is cheaper for receiving ETH?

Usually ETH BEP20, ETH Arbitrum, ETH Optimism works out cheaper. Still, the network is picked by what the recipient accepts, not by the fee.

Q: 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.

Q: What did the YFI to ETH Optimism rate do over the month?

Over the month, plus 0.9%: a low of 0.827985, a high of 0.931415, an average of 0.888589 ETH Optimism per 1 YFI.

Q: Can I swap back, ETH Optimism for YFI?

Yes, the reverse is open too: 1 ETH Optimism = 1.0854 YFI. The link to switch sits under the calculator.

The order runs on autopilot: the rate is locked when you create it, and the payout leaves as soon as the network confirms your transfer. No manual approval, no working hours.

Preliminary figure: the final amount is locked in the order.

Right now 1 YFI gets you 0.921264 ETH Optimism; the other way round, 1 ETH Optimism is 1.0855 YFI. Over 24 hours YFI/ETH Optimism came in at plus 1.85%. Over the week, plus 4.49%.

The weekly range ran from 0.852749 to 0.930213 ETH Optimism, a spread of 9.08%. One order takes from 0.0417853 to 4,030 YFI. In dollars that is roughly $103.70.

The robot sends the payout in the Optimism network, so the address has to belong to that network — a transfer to another one will not arrive. Market capitalisation puts yearn.finance at No. 313 ($89.53 M) and Ethereum at No. 2 ($328.98 B). Over 90 days the daily moves of YFI and ETH correlate at 0.53 (they travel alike).
