OP to KAS: questions and answers
How do I swap OP to KAS without KYC?
Enter the OP amount on this page, paste your KAS address and send your OP to the deposit address shown. AltoSwap has no accounts and asks for no identity documents, and it routes your swap through exchanges rated A for KYC, meaning providers that do not run identity checks. The KAS is paid directly to your wallet.
What is the OP to KAS exchange rate?
The rate moves with the market every few seconds and depends on the amount. The calculator at the top of this page requests live quotes from 20+ exchanges and shows the best current OP to KAS rate for the amount you enter.
What are the minimum and maximum for OP to KAS?
The minimum is about 16.1 OP and the maximum about 5,027,177 OP. Limits vary slightly between exchanges and follow market prices; the form tells you immediately if your amount is outside the range.
How long does a OP to KAS swap take?
Usually 5 to 30 minutes. Most of that is waiting for your OP deposit to confirm on OP Mainnet, which takes about a minute. There is no verification step, so nothing else adds to the wait.
Is swapping OP to KAS anonymous?
AltoSwap does not know who you are (no account, no email, no identity checks) and the default route uses no-KYC exchanges. Both OP Mainnet and Kaspa are public ledgers, though, so the transactions themselves are visible on-chain. For on-chain privacy, swap into a privacy coin such as Monero.
Which KAS address should I use?
Your KAS is paid on Kaspa. Use an address that starts with kaspa:. Always use an address in a wallet you control and double-check the first and last characters before sending.
What fees are included in the OP to KAS rate?
Everything. The exchange's spread, the Kaspa network fee for the payout and any service commission are already inside the quoted rate, so the amount shown is what you receive: exactly on a fixed rate, approximately on a floating rate. You only pay your own OP Mainnet network fee to send the deposit.
Can I swap KAS back to OP?
Yes. The reverse direction, KAS to OP, works the same way and has its own page and live rate on AltoSwap. Each direction is quoted independently, so the two rates are not exact mirrors of each other.
