Payout network for ETH
The same ETH goes out in several networks. Rates and lower limits differ, and the fee is charged by the network itself.

How the USDC BASE → ETH Optimism order runs
- Work out the amount in the calculator: orders start at 200 USDC BASE.
- Enter a ETH address in Optimism and a way to reach you.
- Send USDC BASE in BASE for exactly the amount stated in the order.
- Once the network confirms your transfer, Ethereum leaves for your address. The order page tracks every step.
Check this before sending USDC BASE
- The address network is Optimism. Sending through another network usually means losing the transfer.
- The transfer must not be smaller than 200 USDC BASE.
- Copy the address whole, then compare the first and last characters after pasting.
- Coins go through an AML check: a flagged transfer can be held until the check is finished.

Common questions: USDC BASE → ETH Optimism
What rate does USDC BASE to ETH Optimism run at?
As of Sep 17, 2026 04:33 it is 1 USDC BASE = 0.000410692 ETH Optimism. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $0.994709.
What amounts does USDC BASE → ETH Optimism accept?
From 200 to 10,000,000 USDC BASE per order. The lower limit is roughly $199.93.
Where does the 200 USDC BASE floor come from?
Network fees and order handling eat a small transfer alive — below 200 USDC BASE the swap stops making sense for either side.
What else is taken on top of the rate?
The payout is already calculated at the rate in the calculator. On top of it you only pay the network fee for sending USDC BASE, and that one goes to the blockchain, not to us.
How long does USDC BASE to ETH Optimism take?
The clock starts with confirmations: the order goes into work once BASE confirms your transfer. After that it comes down to how busy the network is.
Which network will ETH Optimism arrive in?
The payout leaves in Optimism. Make sure the receiving wallet works with that network.
Where is receiving ETH cheaper?
The cheapest is usually ETH BEP20, ETH Arbitrum, ETH Optimism. Still, the network is chosen by what the recipient supports, not by the fee.
What if the rate moves while I am paying?
The rate is pinned to the order and does not move while the order is alive. It can be recalculated if the payment arrives late or for a different amount — so send the exact sum, and send it promptly.
Can I go back, ETH Optimism to USDC BASE?
Yes, the reverse direction is open: 1 ETH Optimism = 2,447.17 USDC BASE. The link sits right under the calculator.
