The New Frontier: How 18 U.S.C. § 1960 Is Being Weaponized Against DeFi Developers

In my 25 years as a federal prosecutor, I witnessed the Department of Justice evolve from treating cryptocurrency as a niche novelty to viewing it as a primary enforcement priority. Today, as a federal criminal defense attorney, I am seeing something far more troubling: the aggressive expansion of 18 U.S.C. § 1960, the unlicensed money transmission statute, to encompass developers of decentralized finance protocols who never touch a single dollar of user funds. The current enforcement posture, as articulated in the July 2026 memorandum from the Deputy Attorney General, directs every U.S. Attorney's Office to prioritize cases against "unlicensed money transmitters" operating in the digital asset space, with particular emphasis on non-custodial wallet providers and automated market makers. This represents a fundamental shift in how the government conceptualizes money transmission, moving away from the traditional requirement that a person actually receive and transmit currency toward a theory of "facilitation" that stretches the statutory text to its breaking point. The practical consequence for my clients is that a software engineer who wrote smart contract code in Wyoming can now face a federal indictment in the Southern District of New York simply because a user in Manhattan executed a swap through that protocol. I am currently defending three such cases, and I can tell you that the government's theory relies heavily on the interpretive guidance from FinCEN's 2019 ruling that administrators of decentralized applications may be considered money transmitters, a position that multiple federal district courts have begun to question but which the DOJ continues to press with full force.

The statutory language of 18 U.S.C. § 1960 makes it a crime to operate an unlicensed money transmitting business that "affects interstate or foreign commerce," a jurisdictional hook that is almost impossible to defeat in the internet age. What makes these cases particularly dangerous for defendants is the government's reliance on 31 U.S.C. § 5330 and the implementing regulations at 31 C.F.R. § 1010.100, which define money transmission as "the acceptance of currency, funds, or other value that substitutes for currency" followed by "the transmission of currency, funds, or other value that substitutes for currency to another location or person." The critical battleground in these cases is whether a non-custodial smart contract protocol that merely facilitates peer-to-peer swaps constitutes "acceptance" and "transmission" within the meaning of the statute. I have successfully argued in pre-trial motions that when a user interacts directly with a smart contract without any intermediary taking custody, the developer cannot be said to have accepted or transmitted anything, and that the government's theory would criminalize the creation of any software tool that enables financial transactions. The government counters with the argument that the developer's ongoing maintenance of the protocol and collection of transaction fees constitutes a continuing course of conduct that satisfies the statutory elements, and they point to the Second Circuit's broad reading of "money transmission" in United States v. Velastegui (2024) as supporting authority. Defense counsel must be prepared to litigate this issue aggressively at the motion to dismiss stage, because once the case goes to trial, the jury instructions on this question will be heavily contested and the government will have the advantage of the presumption that their interpretation of the statute is correct.

Blockchain Tracing Under Fire: Challenging the Government's Forensic Methodology

One of the most critical developments in federal cryptocurrency defense over the past eighteen months has been the emergence of Daubert challenges to the government's blockchain tracing experts, and I have made this the centerpiece of my defense strategy in every digital asset case I handle. The DOJ now routinely employs forensic blockchain analytics firms like Chainalysis and TRM Labs to produce transaction graphs that purport to trace the flow of illicit funds from victims to defendants, and these reports are often presented to grand juries and trial juries as near-infallible scientific evidence. In my experience, however, these tracing methodologies are far less reliable than the government represents, and they frequently rely on probabilistic clustering algorithms that make assumptions about address ownership that cannot withstand rigorous scrutiny. The underlying problem is that blockchain tracing is not a hard science like DNA analysis or fingerprint comparison; it is a statistical inference process that depends on the analyst's subjective judgment about which transactions are relevant and how to interpret ambiguous on-chain data. I have deposed Chainalysis experts in three separate cases over the past year, and in each instance I was able to identify significant gaps in their methodology, including the use of heuristic clustering rules that have never been peer-reviewed or validated through any recognized scientific process.

The Federal Rules of Evidence, specifically Rule 702 as interpreted by the Supreme Court in Daubert v. Merrell Dow Pharmaceuticals, requires that expert testimony be based on reliable principles and methods that have been reliably applied to the facts of the case, and I believe that blockchain tracing evidence frequently fails this standard. In a recent case in the Northern District of California, I filed a comprehensive Daubert motion arguing that the government's blockchain expert could not demonstrate an error rate for his clustering methodology, that his conclusions were not falsifiable, and that he had not applied any generally accepted standards for determining when two blockchain addresses belong to the same person. The court granted my motion in part, excluding the expert's opinion that a particular address belonged to my client because the government could not produce the underlying data or code used to reach that conclusion. This ruling created a chain reaction in the case, because without the tracing evidence, the government could not establish the essential link between the stolen funds and my client's wallet, and the case ultimately resolved on highly favorable terms. I am now seeing more defense attorneys adopt this approach, and I expect that the reliability of blockchain tracing will become a central battleground in cryptocurrency cases for years to come. The key is to retain your own blockchain forensic expert early in the case, preferably before indictment, so that you can identify weaknesses in the government's tracing before they become entrenched in the government's theory of the case.

Willful Blindness and the Mens Rea Problem: Fighting Back Against Constructive Knowledge

The most dangerous legal doctrine in federal cryptocurrency prosecutions is the government's increasing reliance on "willful blindness" jury instructions to satisfy the mens rea requirement for crimes like money laundering under 18 U.S.C. § 1956 and bank fraud under 18 U.S.C. § 1344, and I have made challenging this instruction a non-negotiable part of my defense strategy. The theory works like this: the government concedes that it cannot prove the defendant actually knew that the funds in a transaction were derived from criminal activity, but it argues that the defendant deliberately avoided learning the truth by failing to conduct adequate due diligence or by ignoring obvious red flags. The model instruction, drawn from the Pattern Criminal Jury Instructions for the Federal Courts, tells jurors that they may infer knowledge if they find that the defendant was aware of a high probability of illegal activity and deliberately took steps to avoid confirming that suspicion. In the cryptocurrency context, this instruction becomes extraordinarily dangerous because the government can point to any number of routine business practices—such as using privacy coins, transacting through mixers, or accepting funds from known high-risk exchanges—as evidence that the defendant must have suspected something was wrong. I have seen prosecutors use this instruction to effectively eliminate the government's burden of proving specific intent, turning what should be a difficult mens rea case into a simple question of whether the defendant was negligent in failing to investigate further.

The Supreme Court's decision in Global-Tech Appliances v. SEB S.A. (2011) established the constitutional standard for willful blindness, requiring that the defendant must subjectively believe that there is a high probability of illegal conduct and must take deliberate actions to avoid learning the truth, but the lower courts have applied this standard inconsistently in cryptocurrency cases. In my practice, I have found that the most effective way to combat a willful blindness instruction is to present affirmative evidence of my client's compliance efforts, including documented know-your-customer procedures, suspicious activity reports filed with FinCEN, and correspondence with outside counsel seeking legal guidance on regulatory compliance. The government cannot argue that a defendant deliberately avoided knowledge when the defendant can demonstrate that they actively sought information and took steps to comply with the law, even if those steps were imperfect. I also routinely request a special jury instruction that distinguishes between mere negligence or foolishness and the deliberate avoidance of knowledge required for willful blindness, and I cite the D.C. Circuit's opinion in United States v. Alston-Graves (2006) for the proposition that the instruction should not be given when the evidence supports only a theory of negligence. The bottom line for defense counsel is this: you must address the willful blindness issue before trial, not during closing arguments, because once the instruction is given, the damage is largely done and the jury will have a license to convict based on what the defendant should have known rather than what they actually knew.

FAQ: Critical Questions in Federal Cryptocurrency Defense

Q: Can I be charged with unlicensed money transmission if I only operated a peer-to-peer cryptocurrency exchange and never touched fiat currency?

Yes, and this is precisely the theory the DOJ is pursuing in multiple jurisdictions across the country. The government takes the position that cryptocurrency itself constitutes "value that substitutes for currency" under 31 C.F.R. § 1010.100, and that any person who facilitates the transfer of cryptocurrency from one person to another for compensation is engaged in money transmission. The key question is whether you had custody or control over the funds at any point, because the courts have consistently held that mere facilitation without custody does not constitute money transmission. However, the government will argue that even non-custodial platforms exercise sufficient control through smart contract administration, fee structures, and the ability to pause or modify transactions. You need an attorney who can file a pre-trial motion challenging the government's statutory interpretation and who can present expert testimony on how your particular platform operated to demonstrate that you never accepted or transmitted funds within the meaning of the statute.

Q: What is the best defense if the government has blockchain tracing evidence linking my client to stolen funds?

The best defense is to challenge the reliability of the tracing methodology before trial through a Daubert motion, and I have found that this approach succeeds far more often than most defense attorneys realize. The government's blockchain experts cannot typically demonstrate that their clustering algorithms have been peer-reviewed, that they have a known error rate, or that they have been applied consistently across different cases. You should retain your own blockchain forensic expert to conduct an independent analysis of the same transaction data and identify specific errors or assumptions in the government's tracing. In my experience, the government's tracing often relies on "taint analysis" that attributes all funds in a cluster to the same source based on probabilistic heuristics that have never been validated. If you can exclude the tracing evidence, the government will often be unable to prove the essential elements of the offense, and you will have strong leverage for a favorable resolution.

Your Next Move: Protecting Your Freedom in an Aggressive Enforcement Environment

If you are reading this article because you or someone you care about is under investigation or has been charged with a federal cryptocurrency offense, you need to understand that the window for effective intervention closes quickly and that the decisions you make in the first weeks after learning of an investigation will determine the outcome of your case. The DOJ's Cryptocurrency Enforcement Unit, established in 2025 and now operating with over 60 dedicated prosecutors, has made clear that there will be no leniency for defendants who fail to take proactive steps to demonstrate their cooperation and compliance. I have spent the past three years developing a comprehensive defense framework that combines aggressive pre-indictment advocacy with cutting-edge blockchain forensic analysis, and I have used this framework to secure declinations, dismissals, and favorable plea agreements for clients who were facing decades of federal prison time. The most important thing you can do right now is to preserve all records of your cryptocurrency transactions, communications with legal counsel, and compliance procedures, and to retain counsel who has both the technical expertise to challenge the government's evidence and the trial experience to take a case to verdict if necessary. Do not assume that the government's case is stronger than it actually is, and do not let fear drive you into accepting a plea agreement that does not reflect the weaknesses in the government's theory. Call my office today for a confidential consultation, and let us begin building the defense that will protect your liberty, your reputation, and your future.
