AML check on Kaspa

Kaspa (KAS) is a proof-of-work BlockDAG coin whose addresses start with "kaspa:". Here is how to recognise one and what an AML check on it can show.

Address formatStarts with kaspa: · lowercase letters and digits; the prefix is part of the checksumkaspa:qpkhq3m7qtpxnepj58ejwqg5amhqsthf4n4v04fg8ygeajtu9nz2wm3guzlx2Example for illustration, not a real address.
Note

Always paste the full address, including the "kaspa:" prefix, because the prefix is part of the checksum. Neither Tether nor Circle lists Kaspa as a native network for USDT or USDC, so check the network carefully if someone offers stablecoins "on Kaspa".

How to check a Kaspa address

  1. Get the public addressAsk your counterparty for the address they will send from — or copy it from the incoming transaction.
  2. Pick a service that covers KaspaChoose one marked “Supported” in the list above. Make sure your AML checker explicitly lists Kaspa (KAS) as supported, and paste the complete address. An address starting "kaspatest:" is a testnet address, not a mainnet one.
  3. Run the check and read itKaspa adds 10 blocks per second, so an address's history can change within seconds. Run the check again just before you send or accept a large payment instead of relying on an old result.
A real AML check needs only a public address. Never share a seed phrase or private key.

Kaspa specifics

  • Kaspa is a proof-of-work cryptocurrency built as a BlockDAG instead of a single chain: blocks mined at the same time are not thrown away but are put in order (kaspa.org points to the PHANTOM/GHOSTDAG research paper for how this works).[1]
  • The Crescendo hard fork raised Kaspa's block rate from 1 to 10 blocks per second. Its mainnet activation was set for DAA score 110,165,000, expected around 15:00 UTC on 5 May 2025.[2]
  • Under Crescendo (KIP-14, now marked Active) the target time between blocks fell from 1,000 to 100 milliseconds, and the coin-emission schedule was redefined per second so that total issuance per second stayed on the same schedule.[3]
  • Like Bitcoin, Kaspa uses the UTXO model: coins are tracked as separate unspent transaction outputs rather than as one balance per account.[4]
  • According to kaspa.org, mainnet launched in November 2021 with no premine, insider allocation or pre-sales, and every coin in circulation has been mined in the open since genesis.[5]

FAQ

What does a Kaspa address look like?

It starts with “kaspa:” followed by lowercase letters and digits. The prefix is part of the address checksum, so paste the whole address, prefix included. An address starting “kaspatest:” is a testnet address.

Is there USDT or USDC on Kaspa?

Not natively. Kaspa is not on Tether's list of supported networks for USDT or on Circle's list of networks for native USDC. Confirm which network you are using before you send or accept a stablecoin.

Why is Kaspa called a BlockDAG, and how fast is it?

Instead of keeping one chain and throwing away competing blocks, Kaspa keeps blocks mined at the same time and puts them in order. Since the Crescendo upgrade in May 2025 the network targets 10 blocks per second, up from 1.

How do I check a Kaspa address for AML risk?

Copy the public address, open one of the services listed above that supports Kaspa, and run the check. You never need a seed phrase or private key.

What does “Not verified” mean?

The service claims support somewhere — in marketing copy or a third-party page — but its own docs, pricing or FAQ do not list the network. Treat it as unknown.
