How the swap works
-
Type the OP amount and paste your Arbitrum payout address on Arbitrum One.
-
Press Exchange to open the live quote and the deposit address for this order.
-
Broadcast OP to that deposit. After the required confirmations, ARB is sent to your wallet.
Check these before you send
- 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 has not appeared yet, wait a few minutes and refresh the wallet. When the order already shows a payout tx, contact support with your order ID.
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 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.
Arbitrum — leading Ethereum rollup
ARB is the governance token of Arbitrum One — an optimistic rollup with EVM compatibility and wide DeFi adoption.
ARB not received?
Confirm your wallet is on Arbitrum One and fully synced.
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.

Frequently asked questions
Does OP to ARB require KYC or an account?
No. PeakSwap does not ask for a profile, ID documents, or a hosted balance for Optimism to Arbitrum.
How long until ARB arrives?
Many orders finish in a few minutes. Optimism mainnet deposit confirmations and Arbitrum One payout time set the wait.
Do you hold OP or ARB for me?
No. You send OP from a wallet you control and ARB is paid to the address you provide — PeakSwap does not keep a user wallet.
What if I send OP on the wrong chain?
Use Optimism mainnet exactly as shown on the order. A wrong-network send may not be credited — read the swap safety notes first.
