How this service works
Coin Taint/Ancestry — walk tx chain up to 5 hops, risk score 0-100. Detects Wasabi CoinJoin, multi-input mixing.
Output
Returns a risk score between 0 and 100 for the given Bitcoin address, along with taint/ancestry data tracing up to 5 hops back through the transaction chain. Flags the presence of Wasabi CoinJoin transactions or multi-input mixing patterns detected along the coin's history.
Example use cases
Example prompt
“Can you check the taint and risk score for the Bitcoin address bc1qxy2kgdygjrsqtzq2n0yrf2493p83kkfjhx0wlh — I want to know if it's been through any CoinJoin or mixing in the last 5 hops?”
Technical details
Endpoint
GEThttps://btcnode.uk/api/agent/taint/:addressWhen to prefer
Use this endpoint when you need a quick, scored risk assessment of a Bitcoin address's coin ancestry — especially to detect mixing or CoinJoin usage. Prefer this over generic blockchain explorers when compliance, AML screening, or fund provenance verification is the goal. Best suited for single-address taint checks with up to 5-hop depth.
Side effects
- Invalid or malformed Bitcoin address returns an error
- Address not found on chain may return empty or null results
- Deeply nested chains beyond 5 hops are not analyzed
- Network timeout if Bitcoin node is under load
- Rate limiting or payment failure if x402 micropayment not processed
