Scam investigation and blockchain tracing: from victim statement to labeled graph
What tracing can and cannot prove
On-chain analysis can show that funds moved from wallet A to contract B, were swapped into asset C, bridged to chain D, and deposited to a tagged hot wallet cluster associated with a centralized exchange. It cannot, by itself, prove criminal intent inside a chat app, nor compel a foreign exchange to freeze assets. Tracing narrows the investigative space so lawyers and law enforcement spend time on viable leads.
Core techniques investigators use
- Address clustering: Heuristics for multi-input transactions (especially on UTXO chains) suggest common ownership until broken by careful wallet behavior.
- Pattern-of-life: Repeated round amounts, time-of-day activity, and interaction with the same router contracts can link “fresh” scam wallets.
- CEX attribution: Deposits to identifiable exchange infrastructure are often the highest-value finding for civil or criminal process—when timelines allow.
- Cross-chain tracking: Official bridges, liquidity networks, and wrapped assets each leave different fingerprints; missing a hop misstates the story.
Quality of victim-provided data
The strongest cases include transaction hashes, exact wallet addresses used for signing, screenshots archived with URLs and dates, and unedited chat logs. If you only remember a brand name but not the domain, investigators lose time reverse-engineering infrastructure that may already be offline. Early preservation beats late heroics—see our process.
Deliverables that help exchanges and police
Busy reviewers want a one-page executive summary, a labeled diagram, and appendices with raw hashes. Jargon without definitions reduces trust; plain language with precise hashes increases it. VaultTrace Recovery structures reports to complement tracing engagements and downstream legal strategy.
