    Exchange in 3 steps

    1. Choose how much OP to send and enter your Ethereum (Base) address on Base mainnet.

    2. Hit Exchange to open your order page with the live rate and deposit details.

    3. Transfer OP to the address on your order — after confirmations, ETH is sent to your wallet automatically.

    What do you need to know?

    • Optimism confirmations are usually fast — often within a minute.
    • Send OP on Optimism mainnet only — not Ethereum, Base, or Arbitrum unless your order says otherwise.
    • Use an Optimism-compatible wallet and address (0x…). Leave enough ETH on Optimism for gas if sending ERC-20 tokens.
    • ETH not visible yet? Wait a few minutes, resync your wallet, then contact support with your order ID if the payout tx is already listed.
