BTC to KAS: Swap Bitcoin for Native Kaspa, No KYC

On this pair the waiting happens on the Bitcoin side. Bitcoin adds a block about every ten minutes, and the deposit needs one to three blocks before the KAS is sent. Kaspa is fast, but it only shortens the payout.

The fee you set in your wallet matters here. With a low fee the transaction can sit in the mempool while other transactions get into blocks first. A normal fee for current conditions gets it confirmed sooner. You can watch it on mempool.espaço by searching your transaction ID.

Once the deposit has its confirmations, most swaps finish within minutes. The rate floats with the market until that moment, then the KAS amount is fixed and sent.

If you need the KAS soon, avoid the very lowest fee option your wallet suggests.

Use Sparrow, Electrum or a hardware wallet for the deposit. Any of the three Bitcoin address types works as the sender: bc1, 3 or 1.

Enter that same address in the refund field. It is where the BTC goes back if the swap cannot finish, so it should be a wallet whose keys you hold. Sending straight from an exchange account is a poor fit, because a refund to the exchange's address may never reach you.

Send exactly the amount the box shows, in one transaction. Sparrow and Electrum let you see the fee before you sign, and on a hardware wallet you confirm the address and amount on the device screen. Check the deposit address on that screen, not only on the computer.

You need a Kaspa wallet before you start. Kaspium on mobile, KasWare in the browser and Kaspa NG on desktop all give a receive address. A Bitcoin wallet cannot hold KAS; the two coins have no shared address format.

A Kaspa address starts with kaspa: followed by lowercase letters and digits. Copy the whole string, prefix included. The same address without the prefix is rejected by the form.

A brand-new Kaspa wallet can receive the payout straight away; it does not need any KAS in it first. After the swap, Kaspa Explorer shows the incoming payment at your address.

Write down the recovery phrase of the new Kaspa wallet before you paste its address anywhere. If the phone or browser profile is lost later, that phrase is the only way back to the KAS.

Both coins are proof-of-work, so many Bitcoin holders see Kaspa as a related bet rather than a different kind of asset. The design is very different, though. Kaspa orders its blocks in a blockDAG, where several blocks can be added in parallel, and since the Crescendo hard fork in May 2025 it runs at roughly ten blocks per second.

People use this pair to put part of a bitcoin balance into that faster network, or to get KAS for payments that settle quickly.

The rate comes from aggregated liquidity from leading crypto markets. The box shows the KAS amount after fees before you send, so there is no guesswork about the payout at the current rate.

Kaspa uses a GPU-friendly mining algorithm, so it also appeals to people who follow proof-of-work mining.

Read the confirmation row as the timetable for this swap. The Bitcoin column is the slower one and sets the total, while the Kaspa column adds only a short wait at the end.

The explorer row tells you where to look while you wait: mempool.space for the deposit, Kaspa Explorer for the payout. The fee column is simple: you pay the Bitcoin fee for your own deposit, and the KAS payout costs you nothing extra.

If a swap cannot be completed, the coins are refunded to the sender address you entered. On this pair that is the Bitcoin address in your refund field.

The status page shows the deposit, the confirmations and the payout. If it stops moving, send your swap ID and the mempool.space link to support@ghostswap.io.

A Bitcoin deposit that has not reached its confirmations yet is not a failed swap. Check its status on mempool.space first: unconfirmed means it is waiting for a block, and the swap moves on by itself once it is included. After the KAS is sent, the payout shows on Kaspa Explorer under your kaspa: address, usually well before your wallet app refreshes. Keep the swap ID until the KAS is in your wallet.
