What is Optimism?

Optimism (OP) is a Layer 2 scaling solution for Ethereum that uses optimistic rollups to make transactions faster and significantly cheaper than on Ethereum mainnet. Optimism is known for its retroactive public goods funding model, which directs network revenue toward open-source projects that benefit the ecosystem. OP is the governance token used for voting on protocol decisions and treasury allocation. Major DeFi protocols including Aave, Uniswap, and Synthetix are deployed on Optimism.

What is Arbitrum?

Arbitrum (ARB) is the most widely adopted Layer 2 scaling solution for Ethereum, using optimistic rollups to dramatically reduce transaction costs and increase throughput while inheriting Ethereum's security. Hundreds of DeFi protocols, NFT platforms, and dApps have deployed on Arbitrum, making it one of the most active Layer 2 ecosystems. ARB is the governance token that allows holders to vote on protocol upgrades and treasury management.

OP to ARB: questions and answers

Everything you need to know about exchanging OP to ARB on GhostSwap.

How long does it take to swap OP to ARB on GhostSwap?

Most OP to ARB swaps are paid out within 5–15 minutes: the OP deposit needs about a minute to confirm on OP Mainnet, then the ARB is sent to your wallet, and Arbitrum One confirms the payout in about a minute. Busy networks can add a few minutes.

How much is 1 OP in ARB?

1 OP is worth about 0.659880 ARB 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 ARB network fee. The rate floats with the market until your OP deposit confirms, so the exchange box shows the exact amount before you send.

Do I need KYC or an account to exchange OP to ARB?

No. GhostSwap has no accounts: you paste the Arbitrum One address that should receive the ARB, send OP from your own wallet, and the ARB goes straight to that address. No email, phone number or ID upload.

What are the fees for converting Optimism to Arbitrum?

The GhostSwap fee is already included in the rate in the exchange box, so the ARB amount you see is what you receive. On top of that, your wallet needs a little ETH on OP Mainnet to pay the OP Mainnet network fee for sending OP.

What wallet should I use to receive ARB?

To receive Arbitrum from your swap, we recommend using MetaMask or Rabby. Make sure your wallet supports the Arbitrum One (Ethereum layer 2) network before starting the exchange. Double-check your ARB address before confirming, cryptocurrency transactions cannot be reversed.

What format is the ARB address?

Use an Arbitrum One address: it starts with 0x followed by 40 hexadecimal characters. Copy it from your wallet and paste it; never type it by hand. Sending ARB to an address on another network can lose the coins.

Can I track my OP to ARB 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 OP payment on Optimistic Etherscan (https://optimistic.etherscan.io) and your incoming ARB on Arbiscan (https://arbiscan.io).

Is it safe to exchange OP for ARB on GhostSwap?

GhostSwap is non-custodial: there is no account balance holding your coins. Your OP deposit is converted and the ARB is sent straight to the Arbitrum One address you enter, so check that address twice, Arbitrum One transfers cannot be reversed.

How does a cross-chain OP to ARB swap work?

Optimism lives on OP Mainnet and Arbitrum on Arbitrum One, two separate blockchains. Instead of a bridge, GhostSwap takes your OP on OP Mainnet and pays native ARB on Arbitrum One, so you never hold a wrapped token or pay bridge fees.

What happens if my OP to ARB exchange fails?

If a swap cannot be completed, the OP is refunded to the OP Mainnet 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.
