Arbitrum to Optimism

Looking for OP on Optimism mainnet? Keep custody of both ends: quote on ToSwap, push Arbitrum from your wallet, collect Optimism automatically once the deposit depth clears. Private by design — no account to open.

    Three steps on ToSwap

    1. Set the ARB 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 ARB amount to the deposit. After Arbitrum One confirms, OP is pushed to your wallet.

    Before you broadcast

    • Arbitrum confirmations are usually fast — often within a minute.
    • Send ARB on Arbitrum One only — not Ethereum, Optimism, or Base unless your order says otherwise.
    • Use an Arbitrum-compatible wallet and address (0x…). Leave enough ETH on Arbitrum for gas if needed.
    • 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.

    Arbitrum — leading Ethereum rollup

    ARB is the governance token of Arbitrum One — an optimistic rollup with EVM compatibility and wide DeFi adoption.

    ARB on Arbitrum One

    Use an Arbitrum One wallet for deposits. Other chains use different assets even with the same ticker.

    Leave enough ETH on Arbitrum for gas on top of the swap amount when required.

    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 ARB → OP?

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

    How fast does OP usually arrive?

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

    Does ToSwap hold my ARB or OP?

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

    What if I send ARB on the wrong network?

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