FAQ

Questions, answered

How does the risk score work?

We trace the flow of funds in and out of an address across the transaction graph (up to several hops), attribute tainted amounts to known entities such as mixers, darknet markets, sanctioned addresses and exchanges, and weight each category to produce a 0-100 score with a full breakdown.

Which blockchains are supported?

Bitcoin and Tron (including TRC20 USDT) are live today. The architecture is multi-chain and more networks are being added.

Is the free check really free?

Yes. Paste any BTC or Tron address and get an instant risk score and source/destination breakdown, no signup required. Higher volumes and the KYT API are on paid plans.

Where does the label data come from?

We aggregate sanctions data (OFAC SDN), public scam and abuse reports, and curated entity tags (exchanges, mixers, markets), then propagate them across clustered wallets.

Can I integrate this into my exchange or wallet?

Yes. The KYT API offers address and transaction checks, real-time monitoring and webhooks, with API keys and rate limits. See the API docs.
