Common questions: USDC Optimism → ERA
What rate does USDC Optimism to ERA run at?
As of Sep 30, 2026 14:05 it is 1 USDC Optimism = 14.8411 ERA. 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 → ERA accept?

Which network will ERA arrive in?
Caldera arrives in its own Caldera network — a plain ERA 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.
