Swap Optimism → Ethereum (Base) (no KYC)

Need ETH on Base mainnet? Stay self-custodial on both legs: read the Web3Swap quote, push Optimism from your wallet, collect Ethereum (Base) once deposit depth clears. No exchange seat to open.

    Three steps on Web3Swap

    1. Enter the OP size and paste the Ethereum (Base) payout address for Base mainnet on this Web3Swap ticket.

    2. Confirm Exchange to lock the live Web3Swap quote and reveal this ticket’s deposit details.

    3. Broadcast exactly that OP amount to the deposit. After Optimism mainnet confirms, 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.
    • If ETH is late, refresh your wallet and re-check the ticket. When a payout hash is already listed, email or SimpleX support with your Exchange ID — Web3Swap has no login that lists expired orders.

    Optimism tickets — L2 ETH and OP tokens

    OP governs Optimism’s rollup. Web3Swap OP tickets need an Optimism wallet — an L1 Ethereum send here is usually unrecoverable.

    OP on Optimism mainnet

    Use an Optimism wallet for deposits. L1 Ethereum or other L2 sends may not be credited.

    Leave enough ETH on Optimism for gas when moving OP or other tokens.

    You receive

    Base ETH tickets — Coinbase L2 rail

    Native ETH on Base is not Ethereum L1. Web3Swap Base tickets need a Base wallet — low fees, fast finality, still no hosted balance.

    Base ETH not received?

    Confirm your wallet is on Base mainnet and fully synced — not Ethereum L1.

    Base ETH payout tips

    • Payouts go to Base — verify your wallet network is Base (chain ID 8453).
    • Check Basescan with the payout tx hash from your order page.
    • Bridging to Ethereum L1 is a separate step after you receive ETH on Base.

    Deposit checklist

    Chain mismatches and bad addresses are the usual failure modes — skim these notes before you fund the deposit.

    FAQ for this route

    Do I need KYC or a Web3Swap login for OP → ETH?

    No. A standard Optimism → Ethereum (Base) ticket on Web3Swap skips signup and ID upload. You stay self-custodial on both legs.

    How soon does ETH usually arrive?

    After the Optimism mainnet deposit is final, many payouts leave within minutes. Congestion on Optimism mainnet or Base mainnet can stretch that — mempools and fees set the clock, not a compliance hold.

    Does Web3Swap custody my OP or ETH?

    No. You broadcast OP from a wallet you control; ETH pays only to the address you paste. Nothing sits as a named Web3Swap balance.

    What if I send OP on the wrong rail?

    Match Optimism mainnet exactly as printed on the Web3Swap ticket badge. A wrong-chain deposit often cannot be credited automatically — verify before you broadcast.
