The Tornado Cash trial, involving co-founder Roman Storm, has drawn significant attention due to its high-stakes implications for developers of noncustodial Bitcoin and crypto technology, as well as privacy-preserving software. Amanda Tuminelli, executive director and chief legal officer for the DeFi Education Fund, closely followed the proceedings, emphasizing the broader impact on the industry.

In the lead-up to the verdict, Tuminelli provided an overview of the three charges against Roman Storm, with a particular focus on the charge of conspiracy to operate an unlicensed money transmitting business. As an expert on 18 U.S. Code § 1960, the U.S. federal law prohibiting the operation of such businesses without a proper license, Tuminelli argued that Storm had not violated this statute in his role in creating and operating Tornado Cash, a crypto mixing service built on Ethereum.

Tuminelli also highlighted the relevance of legislative efforts like the CLARITY Act and the Blockchain Regulatory Certainty Act (BRCA). Both bills include language designed to protect developers of “non-controlling” (noncustodial) crypto technology, stipulating that such developers and purveyors do not require a money transmitting license and should not be subject to existing money transmission laws.

Furthermore, Tuminelli expressed concern about the Department of Justice’s (DoJ) perceived shift away from 2019 FinCEN guidance, suggesting it threatens innovation in the crypto space. This shift, she noted, could lead to continued prosecution of other developers similar to Storm, despite a memo from U.S. Deputy Attorney General Todd Blanche indicating that the DoJ would cease targeting crypto entities, including mixing and tumbling services, for the acts of their end-users. The DeFi Education Fund actively supported these discussions by submitting amicus briefs to the courts for both the Tornado Cash and Samourai Wallet cases, although the former was rejected.

The trial concluded with a guilty verdict for Roman Storm in the Southern District of New York (SDNY) on the charge of conspiracy to operate an unlicensed money transmitting business. The jury reached this decision after three and a half days of deliberation, following a trial that commenced in the middle of last month. Notably, the jury did not come to a unanimous verdict on the other two counts: conspiracy to commit money laundering and conspiracy to violate sanctions.

As a direct consequence of the guilty verdict on the money transmission charge, Roman Storm now faces a potential sentence of up to five years in prison. Following the verdict, the prosecution motioned to remand Storm into custody, asserting he was a flight risk. However, Judge Failla rejected this motion, swayed by the defense’s arguments that Storm had little reason to flee, citing his home in Washington state tied to a $2 million bail bond, his family ties in the U.S., and the strong support from the U.S.-based crypto community. The judge stated that the “stability of the verdict is still in play,” likely referring to an anticipated appeal, and that Storm's “incentives have shifted tremendously,” ultimately denying the prosecution’s request.

Shortly after the verdict, U.S. Attorney for the SDNY, Jay Clayton, issued a statement. Clayton asserted that “Roman Storm and Tornado Cash provided a service for North Korean hackers and other criminals to move and hide more than $1 billion of dirty money.” He further added, “The speed, efficiency, and functionality of stablecoins and other digital assets offer great promise, but that promise cannot be an excuse for criminality. Criminals who use new technology to commit age old crimes, including hiding dirty money, undermine the public trust, and unfairly cast a shadow on the many innovators who operate lawfully. This Office and our partner agencies are committed to holding accountable those who exploit emerging technologies to commit crime.”

Significantly, Clayton’s statement did not acknowledge the memo from U.S. Deputy Attorney General Todd Blanche, which had previously stated the U.S. Department of Justice would “stop participating in regulation by prosecution” in the crypto space and would no longer target virtual currency mixing services for the actions of their end users. Additionally, Clayton did not mention that the vast majority of funds moved through Tornado Cash users were not proven to have been obtained illicitly. This verdict, therefore, sets a critical precedent for the future of crypto development and regulation, emphasizing the ongoing tension between innovation and legal interpretation in the digital asset space.
