In civil claims involving cryptocurrency, from suits against unidentified defendants to commercial disputes over who is entitled to digital assets, blockchain tracing gives litigators a documented account of where the funds went.
Why crypto fraud is hard to prove in court
Crypto disputes often start with a fact pattern that is clear to the client and hard to prove in court. A plaintiff transferred funds to what they believed was an investment platform, a counterparty, or a business partner, and the funds are no longer where they are supposed to be. The recipient may be anonymous, the funds may have moved through many addresses within hours, and the relevant records may sit with exchanges the plaintiff has never dealt with.
Courts have been willing to act on well-documented tracing. In Song v. Defendant 1 (M.D. Fla. 2025), a case against unnamed defendants arising from an alleged investment scheme, the court granted a temporary restraining order covering identified destination wallets and noted that the plaintiff had provided a forensic blockchain tracing report showing where the assets were believed to be held. Relief in any case depends on the court, the claims and the evidence.
Movement patterns that commonly arise in these matters include:
- Rapid transfers through a chain of intermediate wallets after the initial payment
- Funds split into smaller amounts and later consolidated
- Conversion between tokens or between blockchains
- Deposits to exchanges, sometimes offshore, shortly after receipt
- In commercial disputes, assets held in wallets whose control or ownership is contested
What tracing can establish for a civil claim
- Holdings: current balances at destination addresses, which can inform requests for asset restraint
- Transfers: the documented path from the plaintiff's transfer to later destinations
- Exchange touchpoints: deposits to identifiable exchanges and custodians, where account-holder records can be sought by subpoena
- Timelines: a dated sequence that can be matched to communications and representations
- Commingling: where the funds at issue were mixed with other funds, and how that affects what can be traced
In contract and commercial disputes where the question is entitlement rather than wrongdoing, the same work can establish which wallets held what, and when, without taking a position on who is right.
What tracing can’t do in litigation
Tracing does not identify a defendant by name. In persons-unknown claims, identity usually comes from exchange records produced in response to legal process. Discovery before the parties' Rule 26(f) conference generally requires a stipulation or court order, and counsel will decide whether and how to seek it. Privacy coins, mixers and some cross-chain services can limit a trace. Funds held with platforms outside the US may be harder to reach, and tracing cannot establish intent, which is for the finder of fact.
Evidence that helps a crypto fraud claim
- Transaction IDs, sending and receiving addresses, and the chain used
- Exchange statements for the client's own accounts showing the outgoing transfers
- Screenshots and URLs of any platform or website involved
- Messages, emails and call logs with the other party
- Contracts, term sheets or written agreements in commercial matters
- Bank records of fiat payments made to buy the crypto
Early preservation matters. Funds can move quickly, so we recommend contacting counsel and gathering transaction details as soon as possible.
How ChainWatch works with counsel
We begin with a case review, reviewing the transaction details and giving a realistic view of what tracing may show. Complex investigations are scoped and quoted in advance and can cover multiple incidents and multiple chains in one matter.
We deliver written reports that set out addresses, flows, exchange touchpoints and methodology in terms a judge can follow. Litigation support is available on a retainer or hourly basis, including expert reports, declarations supporting motions for restraint or expedited discovery, and ongoing support as records come back from exchanges and the trace is extended. Engagements are confidential.
Civil crypto fraud: common questions
Can a court freeze crypto held in a scammer’s wallet?
Courts have granted early relief on well-documented tracing. In Song v. Defendant 1 (M.D. Fla. 2025), the court granted a temporary restraining order covering identified destination wallets, noting the plaintiff’s forensic tracing report. Whether relief is available in your case depends on the court, the claims and the evidence.
How do we find out who the anonymous defendant is?
Usually through exchange records. If the funds reached an exchange, account-holder information can be sought by subpoena. Discovery before the parties’ Rule 26(f) conference generally requires a stipulation or court order, which counsel can seek.
Can we sue if we don't know who received the funds?
Some plaintiffs have filed against unnamed defendants and used tracing to support early relief. Whether that route suits your case is a question for your attorney.
How quickly can you produce a report for a TRO motion?
It depends on the complexity of the flows. Tell us about any deadline at the assessment stage so we can advise whether it is realistic.
Will exchanges respond to our subpoena?
Many US exchanges have published channels for legal process. Coinbase, for example, directs US legal documents to its registered agent, and Kraken states it shares data in response to subpoenas and court orders. Responses vary by platform and jurisdiction.
Do you only work for plaintiffs?
No. We also assist in commercial disputes over entitlement and can work under a neutral mandate.
ChainWatch is a blockchain-forensics firm, not a law firm, and does not provide legal advice. We do not assess the merits of any claim. Tracing results depend on the available data, and we cannot guarantee that funds will be frozen, that defendants will be identified, or that any amount will be recovered.
