Common questions: USDC Optimism → YFI

As of Oct 1, 2026 01:40 it is 1 USDC Optimism = 0.000408601 YFI. The figure updates on its own, and the calculator always shows the current one. On the market that is around $1.00.

Which network will YFI arrive in?
yearn.finance arrives in its own yearn.finance network — a plain YFI address is all you need.

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.
