The Tornado Cash trial, particularly that of co-founder Roman Storm, carried significant implications for developers of noncustodial Bitcoin and crypto technology, as well as for privacy-preserving software. Amanda Tuminelli, executive director and chief legal officer for the DeFi Education Fund, highlighted the high stakes involved in this case, seeing Bitcoin as included within "DeFi." Her insights, shared during an interview, provided a crucial overview of the three charges leveled against Storm, with a deep dive into the conspiracy to operate an unlicensed money transmitting business charge. Tuminelli, an expert on 18 U.S. Code § 1960, the U.S. federal law prohibiting unlicensed money transmitting businesses, argued that Storm had not violated this statute in his creation and operation of Tornado Cash, a crypto mixing service built on Ethereum.

Beyond the specific charges, Tuminelli and the interviewer discussed broader legislative efforts aimed at protecting crypto developers. They touched upon the CLARITY Act and the Blockchain Regulatory Certainty Act (BRCA), both of which include language designed to safeguard developers of "non-controlling" (noncustodial) crypto technology. These proposed bills stipulate that such developers and purveyors should not require a money transmitting license, nor should they 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, warning that it threatens innovation within the crypto space. She suggested this shift could lead to the U.S. government continuing to press charges against other developers, despite U.S. Deputy Attorney General Todd Blanche's April memo stating the DoJ would cease targeting crypto entities, including mixing and tumbling services, for the acts of their end users. Tuminelli also shared her perspective on the trial's progression and potential defense strategies, while noting the amicus briefs submitted by the DeFi Education Fund for both the Tornado Cash and Samourai Wallet cases, though the former's submission was rejected by the court.

The high-profile Tornado Cash trial concluded in the Southern District of New York (SDNY) with a significant verdict: Roman Storm was found guilty on the second count of his indictment, specifically conspiracy to operate an unlicensed money transmitting business. While this charge resulted in a guilty verdict, the jury did not reach a unanimous verdict on the other two counts, which included conspiracy to commit money laundering and conspiracy to violate sanctions. The guilty verdict on the money transmission charge came after three and a half days of jury deliberation, following a trial that commenced in the middle of last month, and now exposes Storm to a potential sentence of up to five years in prison.

Following the issuance of the verdict, the prosecution motioned to remand Storm into custody, asserting he was a flight risk. However, Judge Failla rejected this motion. Ms. Klein, representing the defense, effectively countered the government's claim by highlighting that Storm had little incentive to flee. Her arguments included the fact that his Washington state home was tied up in a $2 million bail bond, that his daughter (for whom he has partial custody) and girlfriend reside in the U.S., and that his parents are green card holders. Additionally, she pointed out that a significant portion of the crypto community that has supported Storm is U.S.-based and is expected to continue their support throughout his appeal process. Judge Failla acknowledged that while Storm's "incentives have shifted tremendously" due to the conviction, she also noted that the "stability of the verdict is still in play," likely referring to the impending appeal, before 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 emphasized the promise of stablecoins and digital assets but cautioned against using them as an excuse for criminal activity, stating that criminals exploiting new technology for "age old crimes" undermine public trust and unfairly cast a shadow on lawful innovators. Clayton concluded by reaffirming his office's commitment, alongside partner agencies, to hold accountable those who exploit emerging technologies for criminal purposes. Notably, Clayton's statement made no mention of the memo issued by U.S. Deputy Attorney General Todd Blanche, which stated that 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. Furthermore, Clayton did not acknowledge that the vast majority of funds moved through Tornado Cash users were not proven to have been illicitly obtained.
