What amounts does XLM → USDC Optimism accept?

Which network is cheaper for receiving USDC?

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.
