How the USDC Optimism → ETH BASE order runs
- Work out the amount in the calculator and press the exchange button.
- Enter a ETH address in BASE and a way to reach you.
- Send USDC Optimism in Optimism 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 Optimism
- The address network is BASE. Sending through another network usually means losing the transfer.
- 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.
