Most OP to KAS swaps are paid out within 5–15 minutes: the OP deposit needs about a minute to confirm on OP Mainnet, then the KAS is sent to your wallet, and Kaspa confirms the payout in a few minutes. Busy networks can add a few minutes. ### How much is 1 OP in KAS? 1 OP is worth about 3.4100 KAS at the market rate, before fees (market prices, 12 Oct 2026). GhostSwap's quote in the exchange box already includes the service fee and the KAS 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 KAS? No. GhostSwap has no accounts: you paste the Kaspa address that should receive the KAS, send OP from your own wallet, and the KAS goes straight to that address. No email, phone number or ID upload. ### What are the fees for converting Optimism to Kaspa? The GhostSwap fee is already included in the rate in the exchange box, so the KAS 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 KAS? To receive Kaspa from your swap, we recommend using Kaspium or KasWare. Make sure your wallet supports the Kaspa network before starting the exchange. Double-check your KAS address before confirming, cryptocurrency transactions cannot be reversed. ### What format is the KAS address? Use a Kaspa address: it starts with kaspa:. Copy it from your wallet and paste it; never type it by hand. ### Do I need a Public key to receive KAS? Only if the KAS goes to an exchange or custodial account that gave you a Public key; enter it in the field shown in the exchange box. A personal KAS wallet does not need one. ### Can I track my OP to KAS 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 KAS on Kaspa Explorer (https://explorer.kaspa.org). ### Is it safe to exchange OP for KAS on GhostSwap? GhostSwap is non-custodial: there is no account balance holding your coins. Your OP deposit is converted and the KAS is sent straight to the Kaspa address you enter, so check that address twice, Kaspa transfers cannot be reversed. ### How does a cross-chain OP to KAS swap work? Optimism lives on OP Mainnet and Kaspa on Kaspa, two separate blockchains. Instead of a bridge, GhostSwap takes your OP on OP Mainnet and pays native KAS on Kaspa, so you never hold a wrapped token or pay bridge fees. ### What happens if my OP to KAS 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: KAS to OP](https://ghostswap.io/exchange/kas-op/) ([Markdown](https://ghostswap.io/exchange/kas-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)
