Optimism to Arbitrum

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

    Three steps on ToSwap

    1. Set the OP amount and paste the Arbitrum address that should collect payout on Arbitrum One.

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

    3. Send exactly that OP amount to the deposit. After Optimism mainnet confirms, ARB is pushed 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 ARB 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.

    ARB payout tips

    • Payouts go to Arbitrum One — use a 0x-style address on the correct chain.
    • Check Arbiscan with the payout tx hash if your balance has not updated.
    • Do not expect ARB on Ethereum mainnet unless your order explicitly lists it.

    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 OP → ARB?

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

    How fast does ARB usually arrive?

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

    Does ToSwap hold my OP or ARB?

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

    What if I send OP on the wrong network?

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