Bitcoin.
Paste a transaction id, pick the amount, and we trace it both ways — back to its attributed inputs and forward to later spends — using FIFO or proportional haircut taint on a UTXO graph. We screen structural CoinJoin patterns, address-poisoning bait, selected public exchange and illicit labels, and OFAC-listed Bitcoin addresses, then explain a heuristic risk score.
- Bidirectional FIFO or haircut taint trace, fully in-browser
- CoinJoin / mixer + address-poisoning detection
- OFAC Bitcoin data + selected public labels, heuristic risk score
Left of the selected UTXO = attributed provenance; right = later spends. Each arrow is one transaction link, numbered in trace order; click any UTXO or arrow to open it on mempool.space. A red diamond marks a conservatively stopped CoinJoin heuristic boundary.
Heuristic score for triage only — not legal or financial advice. Absence of a flag is not proof funds are clean.

How tracing works
We load the transaction's outputs so you choose exactly which output (amount) to follow, and how many hops to trace each way.
Backward we attribute provenance to funding inputs; forward we follow later spends. FIFO preserves exact ordered satoshi ranges, while haircut apportions value proportionally with exact integer conservation.
Every hop is screened for conservative CoinJoin structure heuristics (Wasabi, Whirlpool and generic equal-output patterns), where input/output attribution is unreliable, and for low-value address-poisoning look-alikes. Known labeled endpoints stop that branch.
A heuristic risk score is computed from the sanctions, mixer, CoinJoin, poisoning and structural signals found in the bounded graph — both directions.
Disclaimer. This tool is for informational and educational triage only — it is not legal, financial, compliance or investigative advice. Tracing relies on heuristics and third-party data (mempool.space, public labels) that may be incomplete, outdated or wrong; the AML score is an indicator, not a verdict. Absence of a flag is not proof that funds are clean, and a flag is not proof of wrongdoing.
