Investigations
On-chain investigations for law firms, law enforcement and government.
BlockQuery is the investigations arm of Chainlabs. We trace where the funds went, name the entities behind the addresses and produce evidence that survives scrutiny. From a single disputed matter to a jurisdiction-wide intelligence picture.
Government and law enforcement
A wide view of the illicit economy across jurisdictions and corridors, not single-transaction enforcement detail. Structured briefings framed for decision-makers.
Law firms
Court-ready evidence, asset tracing and expert testimony, delivered quietly behind your practice. Cases go out under your brand or ours, your choice.
Compliance and risk teams
Counterparty screening and exposure monitoring, backed by the same address intelligence and returned as a plain-language risk verdict.
How a matter runs
-
You brief us
The matter, the addresses and what you need to prove. NDAs from first contact and a conflict check before we engage.
-
We trace the funds
Across 30+ blockchains, naming the exchanges, desks and services the value moved through on the way out.
-
You get the evidence
A written report with the fund flow, a structured transaction schedule and a straight assessment of what is realistically recoverable.
-
We stand behind it
Senior investigators are available for sworn statements, expert testimony and rebuttal analysis when a matter reaches court.
Scoped per matter, with the cost agreed before the work starts. Intelligence deployments for government teams are scoped separately.
How we work with firms
Cases delivered under your firm's brand or ours. Court-ready output either way, and your client relationship stays yours.
A fast, low-cost first look that tells you whether a matter is worth taking, before you invest the hours. Take it on, decline, or take it on risk.
Up to 10% on cases you refer, so the incentives are aligned and the fee conversation is settled up front.
NDAs from first contact, conflict checks before we engage, and discreet handling throughout. Deployment can stay inside your perimeter where the work is sensitive.
Provenance
Powered by Chainlabs.
Chainlabs has spent six years building one of the largest entity attribution datasets in crypto, naming the exchanges, OTC desks, funds, miners and treasuries behind on-chain addresses. Every investigation runs on that same layer, which is why a trace can name the counterparty rather than stop at an address.
90,000 addresses attributed through direct research, hundreds of millions more through entity clustering - 312M+ on Bitcoin, 47M+ on Ethereum, 94.4M+ on Tron. Around 300 new attributions added monthly.
Human-verified by a team of intelligence analysts, not purely algorithmic.
Verifiable source evidence behind each attribution.
Questions
What does a BlockQuery investigation produce?
A written report: the fund flow from the addresses you give us, a structured transaction schedule you can submit to an exchange or a court, the named entities the value moved through, and a straight assessment of what is realistically recoverable.
Can BlockQuery give expert testimony in court?
Yes. Senior investigators are available for sworn statements, affidavits, expert testimony and rebuttal analysis. Evidence packages are built to be court-ready by default rather than reworked later.
Do you work under our firm's brand?
If you want us to. Cases can be delivered white-label under your firm's brand or under ours. The client relationship stays with you either way, and we work behind your practice rather than alongside it.
How do you decide whether a case is worth taking?
With a triage report. It is a fast, low-cost first look that comes back with a clear call: take the matter on, decline it, or take it on risk. It exists so you only spend real hours on the matters that justify them.
Which blockchains can you trace across?
30+ blockchains, with Bitcoin the deepest. Tracing follows the value across chains and through the exchanges, desks and services it passes, rather than stopping at the first hop.
How does BlockQuery know who is behind an address?
Through the Chainlabs attribution layer: 18,000 commercial entities, including 800+ OTC desks and 480+ regional exchanges, built over six years. Every attribution is human-verified by a team of intelligence analysts and carries verifiable source evidence.
