The Tornado Cash trial has drawn significant attention due to its far-reaching 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, highlighted these high stakes, viewing the case as pivotal for the crypto space.

Roman Storm, a co-founder of Tornado Cash, faced three charges, with particular scrutiny on the accusation of conspiracy to operate an unlicensed money transmitting business. Tuminelli, an expert on 18 U.S. Code § 1960—the federal law prohibiting unlicensed money transmission—argued that Storm's creation and operation of Tornado Cash, an Ethereum-based crypto mixing service, did not violate this statute. The discussion also brought to light legislative efforts like the CLARITY Act and the Blockchain Regulatory Certainty Act (BRCA), which include provisions designed to protect developers of "non-controlling" (noncustodial) crypto technology from needing money transmitting licenses or being subject to existing transmission laws.

Further complicating the legal landscape, Tuminelli pointed out that the Department of Justice's (DoJ) recent shift away from its 2019 FinCEN guidance threatens innovation within the crypto sector. This policy change, she warned, could pave the way for the U.S. government to continue prosecuting developers like Storm, despite an April 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 actions of their end users. The DeFi Education Fund actively participated by writing and submitting amicus briefs to the courts for both the Tornado Cash and Samourai Wallet cases, although the brief for the Tornado Cash case was ultimately rejected.

The trial culminated with Roman Storm being found guilty on the second count of his indictment: conspiracy to operate an unlicensed money transmitting business. This verdict was delivered in the Southern District of New York (SDNY) after three and a half days of jury deliberation, following a trial that commenced in the middle of the previous month. The jury, however, did not reach a unanimous verdict on the other two charges—conspiracy to commit money laundering and conspiracy to violate sanctions.

Following the guilty verdict on the money transmission charge, Storm now faces a potential prison sentence of up to five years. The prosecution promptly moved to remand Storm into custody, asserting he was a flight risk. However, Judge Failla rejected this motion. The defense argued that Storm had minimal incentive to flee, citing his Washington state home tied to a $2 million bail bond, his daughter and girlfriend residing in the U.S., his parents being green card holders, and the substantial U.S.-based crypto community supporting him. Judge Failla acknowledged that Storm's "incentives have shifted tremendously" but denied the motion, stating that the "stability of the verdict is still in play," likely referring to the likelihood of an appeal.

Shortly after the verdict, U.S. Attorney for the SDNY, Jay Clayton (also a former U.S. Securities and Exchange Commission chair), 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 that the promise of digital assets "cannot be an excuse for criminality" and that the Office is "committed to holding accountable those who exploit emerging technologies to commit crime." Notably, Clayton's statement made no mention of Deputy Attorney General Todd Blanche's memo, which pledged that the U.S. Department of Justice would cease "regulation by prosecution" in the crypto space. Furthermore, Clayton did not acknowledge that the vast majority of funds transacted through Tornado Cash users were not proven to have been obtained illicitly, highlighting a contentious aspect of the prosecution's narrative.
