Common questions: USDC Optimism → ETH Optimism

What rate does USDC Optimism to ETH Optimism run at?

As of Sep 30, 2026 19:30 it is 1 USDC Optimism = 0.000373264 ETH Optimism. The figure updates on its own, and the calculator always shows the current one. On the market that is around $1.00.

What amounts does USDC Optimism → ETH Optimism accept?

Why can I not swap less than 100.67 USDC Optimism?
