How to Sell Kaspa (KAS) for USDT: 1,000 Confirmations

To sell Kaspa for USDT, create a KAS → USDT order in the swap widget, paste the USDT address you want to be paid to, and send KAS from your Kaspa wallet. On 21 October 2026 the minimum was about 801 KAS (roughly $30 at $0.0375 per KAS), the provider credited the deposit after 1,000 Kaspa confirmations, and the USDT payout fee was 1.3 USDT on TRON or 0.15 USDT on BNB Chain. Typical processing on this route was 18–20 minutes.

Why 1,000 confirmations is less than it sounds

On most chains a confirmation means one block. Kaspa is a blockDAG that produces blocks in parallel: since the Crescendo hard fork in 2025, the network targets 10 blocks per second. One thousand blocks therefore pass in about 100 seconds. Before Crescendo, at one block per second, the same number took over 16 minutes.

Why so many blocks? Because each Kaspa block is a tiny slice of time. What protects a payment is how much proof-of-work has been built on top of it; at 10 blocks per second, 1,000 blocks is roughly the same span of time and work that a few confirmations represent on a slower chain. The Kaspa confirmations explainer goes deeper into GHOSTDAG ordering.

The whole timeline

The confirmation wait is short, but the provider quoted 18–20 minutes for KAS routes in total, which includes processing after the deposit is credited. In practice:

• 0–10 seconds — your Kaspa transaction is accepted into the DAG and the order page detects it.
• about 100 seconds — 1,000 confirmations, deposit credited.
• up to about 20 minutes — processing and the USDT payout.
• seconds to a minute — the payout confirms on BNB Chain or TRON.

If the order page shows the deposit as detected but not credited after 10 minutes, check your transaction in a Kaspa explorer: an accepted transaction with growing confirmations is fine; one that never appeared was not broadcast.

Choosing where to get paid

On small sales the payout fee is a visible share: 1.3 USDT is over 4% of a $30 sale. If you can use USDT on BNB Chain, that option keeps more. If the next stop is an exchange or a P2P buyer that only takes TRC20, the extra $1.15 buys you not having to swap again.

Sending KAS correctly

1. Enter the KAS amount in the widget (above the minimum, which moves with the KAS price) and check the USDT quote.
2. Paste your USDT address for the payout network and create the order.
3. In Kaspium, KasWare, Kaspa NG or Tangem, send exactly the shown amount to the kaspa:q… deposit address. Kaspa deposits need no memo.
4. Kaspa fees are tiny; leave the default fee. Do not try to send your whole balance without letting the wallet subtract the fee.
5. Keep the order page open until the USDT hash appears.

Things specific to Kaspa wallets

• Many small UTXOs. If you received KAS from mining payouts, your wallet holds many small coins. A large send may need to combine them, which some wallets do in several steps ('compounding'). Let it finish before you expect the deposit.
• Updated software. Wallets that were not updated for Crescendo can fail to build valid transactions. Update before sending.
• Exchange withdrawals. If you withdraw KAS from an exchange directly to the deposit address, the exchange's withdrawal fee comes off the amount — the arriving KAS must still match the order.

Fixed or float for KAS

Kaspa can move several percent in an hour. With the float rate (1%), your USDT is calculated when the deposit is credited, about two minutes after you send — a short window compared with slow chains, which makes float the sensible default here. Fixed (1.5%) locks the USDT amount for the payment window and is worth the extra half percent mainly on volatile days or for larger amounts.

Selling on an exchange instead

Exchanges that list KAS usually credit deposits after their own confirmation count, then you sell on the order book and withdraw USDT, paying a trading fee and a USDT withdrawal fee, often 1 USDT or more on TRC20. For amounts of a few hundred dollars the costs end up similar; the swap saves the account and the sell order. For very large amounts, an exchange's order book may give a better rate than a single quote — compare before sending.

Whatever route you choose, never send KAS to an exchange deposit address that was generated for another coin, even if the exchange displays it next to KAS; each coin has its own deposit address.
