OP

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.

KAS

What is Kaspa?

Kaspa (KAS) is a proof-of-work cryptocurrency that uses a blockDAG (directed acyclic graph) structure called GHOSTDAG, allowing multiple blocks to be created simultaneously rather than sequentially. This innovation dramatically increases transaction throughput while maintaining the security of proof-of-work mining. Kaspa can process 1 block per second with near-instant confirmations, making it one of the fastest PoW networks in existence. KAS is mined using a GPU-friendly algorithm, making it accessible to individual miners.

OP to KAS: questions and answers

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

How long does it take to swap OP to KAS on GhostSwap?
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 3.5107 KAS at the market rate, before fees (market prices, 11 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.
