The Tornado Cash trial 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 monitored the trial, offering insights into the legal intricacies. Her expertise on 18 U.S. Code § 1960, the federal law prohibiting unlicensed money transmitting businesses, was particularly relevant. Tuminelli argued that Tornado Cash co-founder Roman Storm, in creating and operating the crypto mixing service, had not violated this statute.

Tuminelli detailed the three charges levied against Storm, with a deep dive into the conspiracy to operate an unlicensed money transmitting business charge. Her analysis extended to legislative efforts like the CLARITY Act and the Blockchain Regulatory Certainty Act (BRCA), both designed to protect developers of non-controlling (noncustodial) crypto technology by stipulating they do not require money transmitting licenses. Furthermore, Tuminelli highlighted concerns over the Department of Justice's (DoJ) shift from 2019 FinCEN guidance, viewing it as a threat to innovation and a potential precedent for continued prosecutions against developers despite a memo from U.S. Deputy Attorney General Todd Blanche indicating a move away from targeting virtual currency mixing services for end-user actions.

The Tornado Cash trial concluded with a guilty verdict for Roman Storm on the second count of his indictment: conspiracy to operate an unlicensed money transmitting business. The jury, after three and a half days of deliberation, did not reach a unanimous verdict on the other two counts, which included conspiracy to commit money laundering and conspiracy to violate sanctions. As a consequence of this conviction, Storm now faces a potential prison sentence of up to five years.

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. The defense, led by Ms. Klein, emphasized Storm's strong ties to the United States, including his home tied to a $2 million bail bond in Washington state, his partial custody of his daughter, and his girlfriend and green card holder parents residing in the U.S. The judge noted that the "stability of the verdict is still in play," likely referencing the likelihood of Storm appealing the decision, and acknowledged that his "incentives have shifted tremendously," ultimately denying the motion.

Shortly after the verdict, U.S. Attorney for the Southern District of New York (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 underscored that while stablecoins and digital assets offer promise, this should not excuse criminality, and committed to holding accountable those who exploit emerging technologies for crime. Notably, Clayton's statement did not acknowledge Deputy Attorney General Todd Blanche's memo regarding the DoJ's intent to stop "regulation by prosecution" in the crypto space, nor did he mention the absence of definitive proof that the vast majority of funds moved through Tornado Cash were illicitly obtained.
