A crypto investigation can accurately show that funds moved between blockchain addresses without proving who owned or controlled those addresses. Before relying on its conclusions, check the transaction references, tracing method, assumptions, labels, limits, and evidence linking any address to a person or service. Treat ledger facts, analytical inferences, and identity claims as separate layers that need different kinds of support.
First, identify exactly what the investigation claims
“The funds moved here,” “these addresses belong to one entity,” and “this person controlled the wallet” are different conclusions. Each step adds interpretation beyond the ledger record. Ask the investigator to state the claim precisely and identify which parts are direct observations and which are inferences.
| Claim type | What it means | What can support it |
|---|---|---|
| Transaction fact | A specified transaction transferred an asset between specified addresses on a network. | The relevant chain data and transaction hash, checked against the correct network. |
| Address association or cluster | An analyst believes multiple addresses are related or associated with a service or entity. | The stated method, observations, labels and sources behind the association, with limitations disclosed. |
| Control or identity attribution | A particular person or organization controlled an address or funds at a relevant time. | Appropriate corroborating evidence outside the ledger, such as lawfully obtained account or custodian records. |
A blockchain address is generally pseudonymous: the ledger records transactions, not the beneficial owner’s name. New York State Department of Financial Services guidance dated April 28, 2022, explains that off-chain verification may be needed to strengthen attribution. Its guidance applies to New York-regulated virtual-currency entities; it should not be treated as a universal legal rule.
Check the report’s primary references
Ask for enough detail to locate and review the transactions for yourself or through another qualified reviewer. For each material step, the report should identify:

- The blockchain or network, including the relevant asset where network distinctions matter.
- The transaction hash and sending and receiving addresses.
- The amount and asset transferred, and the relevant date and time, with the time zone or timestamp convention clear where needed.
- The starting point and end point of the trace, plus any intermediate transfers included in the conclusion.
- The data retrieval date and any scope boundaries, such as transactions or chains that were excluded.
Compare the report’s stated transaction facts with the referenced chain data. A matching transaction can confirm that the record exists; it does not, on its own, validate every interpretation built on that record.
Ask how the analysis was produced
Tracing tools can organize and interpret blockchain data, but a report should make its analytical choices inspectable. Request the tool and version, or a clear description of the method if no commercial tool was used; the date the data was retrieved; relevant parameters; and the rules for including or excluding transactions.
If the report groups addresses, ask which clustering heuristics were applied and what evidence supports them. If it assigns labels or risk scores, ask who supplied the labels, what they mean, when they were verified, and whether the score is a direct observation or an analytical assessment. The peer-reviewed 2020 article “Safeguarding the evidential value of forensic cryptocurrency investigations” discusses clustering heuristics and attribution tags as distinct techniques and warns of possible misinterpretation. A cluster or tag is an analytical output, not identity proof by itself.
Ask the investigator to state assumptions, confidence characterization, limitations, and any alternative explanations considered. Another qualified reviewer should be able to follow and, where feasible, reproduce the key steps from the references and method description. Reproducibility helps expose differences in scope or interpretation; it does not automatically establish that the interpretation is correct.
Test any claim about who controlled an address
Ask what specifically connects the address to the named person, business, or service, and when and how that connection was verified. A service association does not identify the particular customer behind an account, and a customer record may still need to be tied to the relevant transaction and time.
Look for independent corroboration where available, such as lawfully obtained exchange or custodian records, account information, communications, device records, or victim records. The investigator should distinguish evidence actually reviewed from records that were unavailable or not obtained. NYDFS notes that analytics may identify institutional or high-risk addresses without identifying the underlying owners absent further verification, including customer-provided information.
Look for gaps and alternative routes
Ask what the investigation could not trace, where a path becomes uncertain, and whether any missing segment changes the conclusion. Virtual-asset service providers and services can complicate tracing, as can mixers, smart contracts, decentralized applications, swaps, and on-chain trading or conversions. The OSCE’s 2026 report, Following the Money: Virtual Assets and Human Trafficking, describes both the usefulness of blockchain analytics and these kinds of limitations.
Also ask whether the conclusion depends on third-party address tags or tool data that can change. NIST’s 2022 Digital Investigation Techniques: A NIST Scientific Foundation Review cautions that digital investigations may miss evidence and that the significance of artifacts can change as software changes. A careful report should make clear which data and version informed its conclusion, rather than implying that a trace is complete simply because it is detailed.

Keep original reports and exports, the chain or network identification, transaction hashes, addresses, collection dates, and screenshots where appropriate. Preserve relevant communications and platform details alongside the on-chain material so later reviewers can understand how the investigation was scoped and what information was available at the time.
For people reporting a suspected cryptocurrency scam, the FBI’s Internet Crime Complaint Center (IC3) recommends retaining transaction hashes, wallet addresses, amounts and asset types, dates and times, and relevant communications, platforms, domains, and identifiers. These records help retain context; they do not independently establish who controlled a wallet.
Use a practical review checklist
- Define the conclusion. Separate movement between addresses, an address cluster or service association, and a claim about a named person’s control.
- Verify the references. Check the network, transaction hashes, addresses, assets, amounts, timestamps, and trace endpoints against the report.
- Inspect the method. Obtain the tool and version or method, retrieval date, parameters, inclusion rules, assumptions, and the basis for clusters, labels, and scores.
- Challenge the attribution. Ask for the evidence connecting an address to an entity or person, its verification date, and independent corroboration.
- Examine gaps. Identify untraced portions, complicating services or contracts, data changes, and plausible alternative explanations.
- Preserve the record. Keep source material and context so a later reviewer can understand and assess the work.
If you are reporting a scam, IC3 also cautions: “Be wary of cryptocurrency recovery services, especially those charging an up-front fee.”
Legal standards for digital evidence and its admissibility differ by jurisdiction. If the investigation may support legal action, have a qualified professional in the relevant jurisdiction assess the evidence and applicable rules rather than assuming a tracing report will be treated the same way everywhere.
