The letter, addressed to U.S. District Judge Katherine Polk Failla, was submitted by U.S. Attorney Jay Clayton, the former chair of the Securities and Exchange Commission (SEC). Clayton argued that establishing a trial date now is essential to avoid further unnecessary delays in the high-profile case. This move comes despite a pending motion from Storm’s legal team seeking a judgment of acquittal on the grounds that the evidence presented in the first trial was insufficient to sustain a conviction. Oral arguments for that motion are currently scheduled for April 9, 2026.
Storm, a dual U.S.-Russian citizen, was a key figure in the creation of Tornado Cash, a non-custodial privacy protocol designed to obscure the link between the sender and receiver of transactions on the Ethereum blockchain. While proponents view the tool as an essential instrument for financial privacy, the U.S. Department of Justice (DOJ) alleges that the service was a primary conduit for money laundering, specifically by state-sponsored actors such as North Korea’s Lazarus Group.
The Legal Landscape and the Partial Verdict
The push for a retrial follows a complex legal outcome in August 2025. After four weeks of testimony and evidence, a jury convicted Storm on one count: conspiracy to operate an unlicensed money-transmitting business. However, the same jury reached an impasse on two more severe charges: conspiracy to commit money laundering and conspiracy to violate the International Emergency Economic Powers Act (IEEPA), which relates to sanctions violations.
The inability of the jury to reach a unanimous verdict on the latter charges resulted in a partial mistrial. Under U.S. law, the government maintains the right to retry a defendant on counts where a jury was deadlocked. Prosecutors now seek to secure convictions on these unresolved charges, which carry significantly heavier potential prison sentences than the unlicensed money-transmitting count.
Storm, who remains free on bail, has been vocal about the implications of the government’s pursuit. In a statement posted to the social media platform X on Tuesday, he argued that the jury’s deadlock was a clear indication of the weakness of the government’s narrative. He framed the case as a fundamental threat to the First Amendment rights of software developers, suggesting that the prosecution seeks to hold authors of code responsible for the subsequent misuse of that code by third parties.
Technical Context: What Is Tornado Cash?
To understand the weight of the Roman Storm case, one must examine the technical nature of Tornado Cash. Launched in 2019, Tornado Cash utilizes zero-knowledge proofs—specifically zk-SNARKs (Zero-Knowledge Succinct Non-Interactive Arguments of Knowledge)—to allow users to deposit funds into a pool and withdraw them to a different address without leaving a trace of the connection on the public ledger.
Unlike traditional financial institutions or even centralized cryptocurrency exchanges, Tornado Cash was designed to be decentralized. The developers argued that once the smart contracts were deployed to the Ethereum network, they became immutable and "self-executing." This means the developers, including Storm, claimed they did not have the power to stop specific individuals from using the protocol or to "freeze" funds, a distinction that sits at the heart of the legal dispute.
The government’s case hinges on the assertion that the developers were not merely "writing code" but were actively maintaining a service that they knew was being used by illicit actors. Prosecutors allege that the Tornado Cash founders received complaints and warnings about criminal activity on the platform but chose not to implement effective Know Your Customer (KYC) or Anti-Money Laundering (AML) controls.
Chronology of the Tornado Cash Legal Saga
The legal troubles for Tornado Cash and its founders began in earnest in 2022, leading to a series of unprecedented regulatory and criminal actions:
- August 2022: The U.S. Treasury Department’s Office of Foreign Assets Control (OFAC) sanctioned Tornado Cash, marking the first time a decentralized protocol (as opposed to a person or entity) was added to the Specially Designated Nationals (SDN) list.
- August 2023: Roman Storm and fellow co-founder Roman Semenov were indicted by the DOJ. Storm was arrested in Washington state, while Semenov remained at large. A third developer, Alexey Pertsev, was arrested in the Netherlands around the same time.
- May 2024: In a separate jurisdiction, a Dutch court sentenced Alexey Pertsev to 64 months in prison for money laundering related to his work on Tornado Cash, a verdict that sent shockwaves through the developer community.
- August 2025: Storm’s first trial in the Southern District of New York concluded with a partial verdict. He was convicted of conspiracy to operate an unlicensed money-transmitting business but saw a hung jury on money laundering and sanctions charges.
- March 2026: U.S. prosecutors filed a request for an October retrial date, while Storm pointed to a new Treasury report as evidence of the protocol’s legitimate utility.
The Treasury Shift and Defense Strategy
A pivotal element in the upcoming proceedings is a recent report from the U.S. Treasury Department. In early March 2026, the Treasury acknowledged that "mixing" services like Tornado Cash provide legitimate privacy functions for users on public blockchains. This acknowledgment represents a nuanced shift from the government’s previous rhetoric, which often categorized mixers almost exclusively as tools for criminals.
Storm’s defense team, led by prominent civil liberties and white-collar defense attorneys, intends to use this report to bolster their argument. They contend that if the government itself admits that these tools have lawful purposes, it becomes much harder to prove that the developers acted with the "specific intent" to facilitate crime—a requirement for a money laundering conviction.
Furthermore, the defense has criticized the prosecution’s haste to set a retrial date. In their communications with the court, Storm’s lawyers argued that it is "premature" to schedule a new trial before Judge Failla has ruled on the motion for acquittal. If the judge grants the acquittal in April, the need for an October trial would be rendered moot.
Broader Implications for the Tech Industry
The outcome of the Roman Storm case is expected to set a major legal precedent regarding the liability of open-source software developers. The core question is whether a developer can be held criminally liable for the actions of users who interact with their autonomous code.
Legal experts have drawn parallels to the "Crypto Wars" of the 1990s, where the U.S. government attempted to restrict the export of strong encryption, viewing it as a munition. In the landmark case Bernstein v. United States, the court eventually ruled that software source code is speech protected by the First Amendment. Storm and his supporters argue that the Tornado Cash prosecution is a modern-day attempt to circumvent that protection.
If Storm is convicted of money laundering and sanctions violations in a retrial, it could have a "chilling effect" on the development of privacy-preserving technologies. Developers may become hesitant to contribute to open-source projects for fear that they could be prosecuted if a malicious actor eventually uses the software. Conversely, the government argues that "privacy" cannot be used as a shield for state-sponsored cybercriminals to launder hundreds of millions of dollars used to fund weapons programs.
Supporting Data and Financial Stakes
The scale of the alleged laundering is central to the government’s pursuit of a retrial. According to the original indictment, Tornado Cash facilitated more than $1 billion in money laundering transactions. This includes over $455 million allegedly stolen by the Lazarus Group, the North Korean hacking collective responsible for the massive Ronin Network heist in 2022.
The government’s pursuit of Storm is also a matter of financial infrastructure security. By targeting the developers of "unlicensed" transmitting businesses, the DOJ aims to force emerging decentralized finance (DeFi) protocols to integrate into the traditional regulatory framework, including the Bank Secrecy Act.
However, the "unlicensed money transmitting" conviction Storm already faces is itself a point of contention. The defense argues that Tornado Cash did not fit the statutory definition of a money transmitter because the developers never had "control" over the funds. In their view, the users controlled the funds via smart contracts, and the developers merely provided the tools.
The Path Forward to October 2026
As the legal community looks toward the April 9 hearing, the tension between national security and digital privacy remains unresolved. The October retrial, should it proceed, will likely involve a new jury and a refined set of arguments from both sides, informed by the results of the first trial.
The prosecution will likely focus more heavily on internal communications among the founders to prove knowledge and intent. Meanwhile, the defense will likely double down on the technical impossibility of the founders acting as a "compliance department" for a decentralized protocol.
For Roman Storm, the stakes could not be higher. While he remains free on bail for now, the unresolved charges carry a maximum combined sentence of 40 years in prison. His fight has garnered significant financial support from the crypto community, including the JusticeDAO, which has raised millions for his legal defense.
As the Southern District of New York prepares for the next phase of United States v. Storm, the case stands as a defining moment for the intersection of law, code, and the future of the internet. The decision made by Judge Failla in April and a potential jury in October will resonate far beyond the walls of the courtroom, potentially redefining the boundaries of criminal liability in the digital age.
