Most OP to BRETT swaps are paid out within 5–15 minutes: the OP deposit needs about a minute to confirm on OP Mainnet, then the BRETT is sent to your wallet, and Base confirms the payout in about a minute. Busy networks can add a few minutes. ### How much is 1 OP in BRETT? 1 OP is worth about 22.6727 BRETT 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 BRETT 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 BRETT? No. GhostSwap has no accounts: you paste the Base address that should receive the BRETT, send OP from your own wallet, and the BRETT goes straight to that address. No email, phone number or ID upload. ### What are the fees for converting Optimism to Brett? The GhostSwap fee is already included in the rate in the exchange box, so the BRETT 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 BRETT? To receive Brett from your swap, we recommend using Coinbase Wallet, MetaMask or Rabby. Make sure your wallet supports the Base (Ethereum layer 2) network before starting the exchange. Double-check your BRETT address before confirming, cryptocurrency transactions cannot be reversed. ### What format is the BRETT address? Use a Base address: it starts with 0x followed by 40 hexadecimal characters. Copy it from your wallet and paste it; never type it by hand. Sending BRETT to an address on another network can lose the coins. ### Can I track my OP to BRETT 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 BRETT on BaseScan (https://basescan.org). ### Is it safe to exchange OP for BRETT on GhostSwap? GhostSwap is non-custodial: there is no account balance holding your coins. Your OP deposit is converted and the BRETT is sent straight to the Base address you enter, so check that address twice, Base transfers cannot be reversed. ### How does a cross-chain OP to BRETT swap work? Optimism lives on OP Mainnet and Brett on Base, two separate blockchains. Instead of a bridge, GhostSwap takes your OP on OP Mainnet and pays native BRETT on Base, so you never hold a wrapped token or pay bridge fees. ### What happens if my OP to BRETT 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. ## Related - [Reverse: BRETT to OP](https://ghostswap.io/exchange/brett-op/) ([Markdown](https://ghostswap.io/exchange/brett-op.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)
