Roman Storm On Trial Is Tornado Cash Code A Crime

In a high-profile federal case unfolding in Manhattan, U.S. prosecutors are seeking to hold Tornado Cash co-founder Roman Storm criminally liable for enabling large-scale crypto laundering, most notably on behalf of North Korea’s Lazarus Group.

The Case Against Roman Storm

Storm faces allegations of conspiracy to commit money laundering and violating sanctions laws, stemming from the $625 million Ronin Bridge hack, which allegedly funneled funds through Tornado Cash. While co-founder Roman Semenov remains at large, Storm is standing trial under intense scrutiny from regulators and the crypto community.

Judge Katherine Failla is presiding over the case, weighing technical sophisticated testimony against constitutional and geopolitical undertones. The trial has run longer than anticipated, with delays arising over witness availability and issues of immunity. Closing arguments are now likely midweek.

FBI Testimony and Legal Gray Areas

Prosecutors presented evidence from FBI agents who traced illicit funds through Tornado Cash’s anonymizing services. Victims of scams and rug pulls have also testified.

But the defense, led by attorney Brian Klein, argues that Storm merely created open-source software, and isn’t  a laundering tool. Klein, has attempted to humanize their client, pointing to his attendance at a hackathon and holding up a T-shirt bearing an image of a washing machine a reference, prosecutors claim, to Tornado’s role in “cleaning” dirty crypto.

The legal ground of the case is shaky. If the mixer’s smart contracts really are immutable and autonomous, can anyone blame them for their abuse?

Crypto, Code, and Constitutional Questions

This case could become a legal turning point: Is it criminal to publish privacy-preserving code? The trial comes just weeks after Tornado Cash sanctions were partially lifted, though the criminal prosecution continues.

The court’s decision may shape how U.S. law treats open-source developers, especially those building privacy-enhancing tech in blockchain ecosystems.

Lawmakers are watching closely as the GENIUS Act, a proposed crypto policy bill, crawls through Congress. The bill seeks to clarify the legal status of decentralized protocols and smart contracts, but it may arrive too late for Storm.

As the trial comes to a turning point, the stakes are not just for one developer. It’s about how much the U.S. government can ask of coders when it comes to code—and whether crypto privacy is welcome in the post-FTX regulatory world.
