Most ARB to OP swaps are paid out within 5–15 minutes: the ARB deposit needs about a minute to confirm on Arbitrum One, then the OP is sent to your wallet, and OP Mainnet confirms the payout in about a minute. Busy networks can add a few minutes. ### How much is 1 ARB in OP? 1 ARB is worth about 1.5171 OP at the market rate, before fees (market prices, 8 Oct 2026). GhostSwap's quote in the exchange box already includes the service fee and the OP network fee. The rate floats with the market until your ARB deposit confirms, so the exchange box shows the exact amount before you send. ### Do I need KYC or an account to exchange ARB to OP? No. GhostSwap has no accounts: you paste the OP Mainnet address that should receive the OP, send ARB from your own wallet, and the OP goes straight to that address. No email, phone number or ID upload. ### What are the fees for converting Arbitrum to Optimism? The GhostSwap fee is already included in the rate in the exchange box, so the OP amount you see is what you receive. On top of that, your wallet needs a little ETH on Arbitrum to pay the Arbitrum One network fee for sending ARB. ### What wallet should I use to receive OP? To receive Optimism from your swap, we recommend using MetaMask or Rabby. Make sure your wallet supports the OP Mainnet (Ethereum layer 2) network before starting the exchange. Double-check your OP address before confirming, cryptocurrency transactions cannot be reversed. ### What format is the OP address? Use an OP Mainnet address: it starts with 0x followed by 40 hexadecimal characters. Copy it from your wallet and paste it; never type it by hand. Sending OP to an address on another network can lose the coins. ### Can I track my ARB to OP swap? Yes. After initiating your swap, GhostSwap provides a transaction status page where you can monitor progress in real-time. You can also track your ARB payment on Arbiscan (https://arbiscan.io) and your incoming OP on Optimistic Etherscan (https://optimistic.etherscan.io). ### Is it safe to exchange ARB for OP on GhostSwap? GhostSwap is non-custodial: there is no account balance holding your coins. Your ARB deposit is converted and the OP is sent straight to the OP Mainnet address you enter, so check that address twice, OP Mainnet transfers cannot be reversed. ### How does a cross-chain ARB to OP swap work? Arbitrum lives on Arbitrum One and Optimism on OP Mainnet, two separate blockchains. Instead of a bridge, GhostSwap takes your ARB on Arbitrum One and pays native OP on OP Mainnet, so you never hold a wrapped token or pay bridge fees. ### What happens if my ARB to OP exchange fails? If a swap cannot be completed, the ARB is refunded to the Arbitrum One address you entered as the sender address. If something looks stuck, contact support with your swap ID from the status page. Most problems come from sending a different amount than shown or using an address on the wrong network. ## Related - [Reverse: OP to ARB](https://ghostswap.io/exchange/op-arb/) ([Markdown](https://ghostswap.io/exchange/op-arb.md)) - [All GhostSwap pairs](https://ghostswap.io/exchange/) - [How to exchange](https://ghostswap.io/how-to-exchange/) - [Site guide for AI assistants](https://ghostswap.io/llms.txt)
