Ethereum (Base) to Optimism

ETH → OP (Optimism mainnet): a privacy-first, non-custodial lane with fees visible before you broadcast. After Ethereum (Base) confirms on Base mainnet, ToSwap pays OP out — typically within minutes, not hours.

    Three steps on ToSwap

    1. Set the ETH amount and paste the Optimism address that should collect payout on Optimism mainnet.

    2. Tap Exchange to lock the live ToSwap quote and reveal this order’s deposit details.

    3. Send exactly that ETH amount to the deposit. After Base mainnet confirms, OP is pushed to your wallet.

    Before you broadcast

    • Base confirmations are usually fast — often within a minute.
    • Send ETH on Base mainnet only — not Ethereum L1, Optimism, or Arbitrum unless your order says otherwise.
    • Use a Base-compatible wallet and address (0x…). Leave enough ETH on Base for gas on top of the swap amount.
    • If OP is late, refresh your wallet and re-check the order status. When a payout hash is already listed, email or SimpleX support with your Exchange ID — ToSwap has no login that can reopen expired pages.
    You send

    ETH on Base — Coinbase L2

    Native ETH on Base — Ethereum's value on Coinbase's L2 with low fees, fast finality, and growing on-chain activity.

    ETH on Base mainnet

    Use a Base wallet for deposits. Ethereum mainnet ETH is a different network — wrong-chain sends may not be credited.

    Leave enough ETH on Base for gas in addition to the amount you swap.

    You receive

    Optimism — Ethereum L2 with low fees

    OP is the governance token of Optimism — an Ethereum rollup with fast, low-cost transfers and deep Superchain liquidity.

    OP not received?

    Confirm your wallet is on Optimism mainnet and fully synced.

    OP payout tips

    • Payouts go to Optimism — verify your wallet RPC is set to Optimism, not Ethereum mainnet.
    • Check Optimistic Etherscan with the payout tx hash from your order page.
    • Allow a minute for your wallet to refresh after the explorer shows the transfer.

    Deposit checklist

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

    Deposit amount must match exactly Under- and over-payments can delay or fail automated crediting. What each swap status means From awaiting deposit to complete — read each status on your order page. How to track swap order status Use your exchange ID and read each status on the order page. What happens when a swap order expires? Deposit windows close — sending late may require a fresh order.

    FAQ for this route

    Is KYC or a ToSwap account required for ETH → OP?

    No. ToSwap never opens a profile or asks for ID documents on a standard Ethereum (Base) to Optimism order. You stay non-custodial on both legs.

    How fast does OP usually arrive?

    Many payouts leave within minutes after the Base mainnet deposit confirms. Congestion on Base mainnet or Optimism mainnet can stretch that — fees and mempools set the clock, not a manual review.

    Does ToSwap hold my ETH or OP?

    No hosted balance. You broadcast ETH from a wallet you control; OP is paid only to the address you paste. Nothing sits under a ToSwap username.

    What if I send ETH on the wrong network?

    Match Base mainnet exactly as printed on the order badge. A wrong-chain deposit often cannot be credited automatically — double-check before you broadcast.
