Exchange in 3 steps

  3. Send OP to that deposit. After confirmations, ETH is paid to your wallet.

Before you broadcast

  • 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.

Base ETH payout tips

Frequently asked questions

Is identity verification required to trade OP for ETH?

No. XmrEx operates as an anonymous no-KYC crypto exchange — no profile, no ID upload, and no funded account for Optimism → Ethereum (Base).

How long is a OP → ETH order?

Typical completion is a few minutes. Optimism mainnet and Base mainnet confirmation times set the pace.

Do you custody OP or ETH?

No. You send OP yourself and ETH is paid to the address you enter — XmrEx does not keep a wallet balance for you.

What if I pick the wrong OP network?

Match the network printed on the order (Optimism mainnet). A mismatch can strand the deposit — check the swap safety notes first.
