Tornado Cash Developer Awaits Judge’s Decision on Acquittal Motion
Roman Storm, co-founder of the privacy-mixing platform Tornado Cash, is awaiting a federal judge’s ruling on his motion for acquittal after a jury delivered a fractured verdict last August.[1][2] Judge Katherine Polk Failla heard arguments on Thursday and now has several weeks to decide whether to dismiss the case entirely or send it to retrial, marking one of the most consequential moments in cryptocurrency developer liability law.[1][2] The outcome will reshape how regulators and courts interpret the legal responsibilities of software creators who build decentralized financial tools-a question that has no clear precedent in existing case law.
Immediate Read
Hung jury signals prosecutorial weakness on intent: Jurors convicted Storm only on unlicensed money transmitting but deadlocked on money laundering and sanctions evasion, suggesting prosecutors failed to prove knowing criminal facilitation.[1][3]
Judge appeared sympathetic to developer defense: During Thursday’s hearing, Judge Failla questioned whether merely creating privacy software constitutes a crime, prompting tension with prosecutors.[2]
Prosecutors claim Storm made 250+ infrastructure changes while publicly denying control: Government alleges these actions prove active operation and concealment of involvement, contradicting Storm’s “passive developer” narrative.[4]
Acquittal motion filing strategy amplifies jurisdictional challenge: Storm’s legal team argues New York prosecution was improper and prosecutors failed to meet their burden of proof on conspiracy elements.[1][2]
Retrial timeline uncertain if motion denied: If Judge Failla rejects acquittal, Storm faces potential retrial later this year on the hung charges, prolonging legal and regulatory uncertainty.[2]
Treasury Department legitimacy argument undercuts criminal framing: Storm’s counsel cited US Treasury recognition of crypto mixers as lawful businesses, directly contradicting federal prosecution’s characterization of Tornado Cash as inherently criminal infrastructure.[1]

The Verdict That Wasn’t
The August 2025 jury verdict split along a critical fault line. Twelve jurors unanimously convicted Storm of conspiracy to operate an unlicensed money transmitting business under 18 U.S.C. § 1960-a charge requiring no proof of criminal intent, only that funds were accepted, transmitted, and controlled.[3][5] But on the two charges carrying up to 20 years each-money laundering conspiracy and sanctions evasion-the jury deadlocked completely.[3][5]
This split is everything. The money laundering and sanctions counts explicitly required jurors to find that Storm knowingly facilitated criminal activity. That they couldn’t agree on those charges after nearly a week of deliberation tells us something prosecutors struggled to prove: direct knowledge of and intent to enable illicit actors.[5] One legal observer noted the deadlock suggested “the jury was not prepared to draw a direct line between Storm’s role as a software developer and deliberate criminal facilitation.”[5]
The money transmitting conviction, by contrast, is almost structurally easier. The statute doesn’t require any nexus to criminal conduct-only that a service accepts and moves funds without proper licensure. Storm’s legal team will argue on the acquittal motion that even this conviction rests on a fundamental misreading of what Tornado Cash actually is: decentralized open-source code, not a business Storm “operated” in any traditional sense.
Storm’s Acquittal Strategy: Jurisdictional and Substantive Angles
Storm’s post-trial motion hits prosecutors from multiple vectors. First, territorial: his attorneys contend the case was improperly dragged into New York’s Southern District when no viable jurisdictional hook existed.[1][2] Second, substantive: prosecutors failed to prove Storm committed any underlying crime, they argue, particularly given the jury’s refusal to convict on intent-based charges.[1][2]
The jurisdictional argument gained traction with Judge Failla during Thursday’s hearing. Prosecutors will need to defend why a software developer’s operations-largely conducted online, with no physical presence in New York-fell properly under the Southern District’s authority. It’s a technical point, but it matters immensely in federal criminal procedure.
The substantive argument is sharper. Storm’s counsel pointed directly to the US Treasury Department’s own stance: crypto mixers like Tornado Cash are recognized as legitimate businesses operating within existing frameworks.[1] If Treasury treats them as lawful, how can prosecutors simultaneously argue that merely creating one constitutes a conspiracy? This creates cognitive dissonance prosecutors must overcome.
The Safeguards Dispute: Central to Prosecutor Credibility
Prosecutors have accused Storm of implementing compliance measures designed to be “window dressing”-controls described internally as “easy to bypass” and introduced mainly to “distract law enforcement.”[4] They also allege Storm made over 250 infrastructure changes to Tornado Cash while publicly claiming minimal involvement, contradicting his defense narrative of a passive code creator.[4]
This is where the case turns visceral. If prosecutors can prove Storm deliberately designed weak safeguards knowing criminals would exploit them, that crosses into knowing facilitation. If Storm can argue those safeguards reflect good-faith compliance efforts-and that the infrastructure changes were routine development work-then the prosecution’s “willful blindness” narrative collapses.
The jury’s inability to agree on money laundering counts suggests neither side fully prevailed on this question. Some jurors may have found Storm’s efforts inadequate; others may have viewed them as reasonable attempts to balance privacy and compliance. Judge Failla will have to weigh the evidence on this critical pivot point.
What a Jury Deadlock Actually Tells Us
Hung juries on intent-based crimes typically signal one of three things: genuine evidentiary weakness, juror disagreement over reasonable interpretation of conduct, or conflicting views on how harshly to judge the defendant’s knowledge state. In Storm’s case, all three likely played a role.
The prosecution’s burden on money laundering was high: prove that Storm knew illicit funds were flowing through Tornado Cash and that he consciously promoted the platform and that he deliberately avoided implementing stronger controls. That’s a chain of inferences. Jurors who viewed Storm’s role as more passive-as a code creator rather than an active business operator-might have broken that chain. Others may have found the evidence of knowledge sufficient but disagreed on intent to facilitate.
This ambiguity is exactly where Judge Failla’s motion for acquittal becomes powerful leverage for the defense. If jurors couldn’t unanimously conclude Storm intentionally furthered money laundering, can prosecutors realistically retry him on that charge? Can a jury of twelve be expected to reach different conclusions on rematch with the same evidence?
The Developer Liability Precedent Looming
This case exists in a vacuum because no appellate precedent clearly defines when a cryptocurrency software developer crosses from creation into criminal operation.[5] Is writing code a “business”? Does maintaining code and receiving donations constitute “operating” a service? Can a developer be convicted of conspiracy to launder money when the platform itself is decentralized and the developer has no control over who uses it?
These aren’t abstract legal questions-they’ll reshape how courts evaluate crypto protocol developers, privacy engineers, and open-source maintainers for years. A ruling acquitting Storm sends a signal: creating privacy tools is constitutionally protected activity unless the government can prove specific intent to facilitate crime. A retrial sends another signal: developers must implement and prove robust compliance regardless of the platform’s decentralized nature.
Judge Failla appears aware of this stakes. Her questions during Thursday’s hearing-particularly whether merely creating Tornado Cash was a crime-suggest she’s grappling with whether existing money transmitting statutes even apply to decentralized software.[2]
Prosecution’s Vulnerability and Doj Reputational Risk
If Judge Failla grants the acquittal motion, prosecutors face a brutal decision: appeal (prolonging uncertainty and inviting appellate scrutiny of their charging theories) or concede. Neither option is clean.[2] The Department of Justice has already reportedly come under internal scrutiny for this prosecution, according to some legal observers.
The prosecution’s Supreme Court copyright ruling citation was rejected by the court as irrelevant-a procedural loss that eroded prosecutorial credibility heading into this motion hearing.[4] That stumble signals their legal theory may be on shakier ground than the indictment suggested.
Uncertainty: What We Don’t Know
No data confirms how long Judge Failla will take to rule or whether she’ll issue a detailed opinion (which would have broader precedential value). The defense team’s internal confidence level remains private. Market participants haven’t priced this ruling into any risk assets, largely because the outcome won’t directly affect Tornado Cash’s operations or price-Storm’s legal status is orthogonal to protocol functionality.
The downside scenario: Judge Failla denies the acquittal motion, Storm faces retrial on money laundering and sanctions charges later this year, and prosecutorial strategy gets a second wind. That would extend legal uncertainty and potentially embolden other agencies to pursue similar developer-liability cases.
The Structural Implication
This case will ultimately hinge on how courts distinguish between enabling a technology and intending to facilitate its misuse. That distinction-between passive creation and active operation-will determine whether the current regulatory framework can absorb privacy-enhancing technologies or whether new legislation becomes necessary. Judge Failla’s ruling will effectively answer whether developers can build tools knowing they may be misused, or whether market mechanisms and user choice alone create sufficient legal exposure to make privacy development economically irrational. That’s not just Storm’s trial. It’s the future architecture of who gets to build financial infrastructure.
