NEW YORK, New York — Tornado Cash developer Roman Storm’s criminal money laundering is slated to begin in Manhattan on Monday morning, when Storm’s lawyers and prosecutors will begin to select a jury to oversee Storm’s four-week trial.

Storm was arrested in Washington state in 2023 and charged with conspiracy to commit money laundering, conspiracy to violate U.S. sanctions, and conspiracy to operate an unlicensed money transmitting business — charges which, if Storm is convicted, carry a maximum combined sentence of 45 years in prison. Storm’s fellow Tornado Cash developer, Russian national Roman Semenov, faces the same charges but remains at large. Another developer, Alexey Pertsev, was convicted of money laundering in the Netherlands in 2024 and sentenced to five years in prison, which he is currently appealing.
At the heart of Storm’s case lies Tornado Cash, a privacy-oriented cryptocurrency mixing service, which the government has alleged was used to launder over $1 billion in criminal proceeds by bad actors — including the Lazarus Group, North Korea’s state-sanctioned hacking operation, which they say constituted a violation of U.S. sanctions — while Storm and his colleagues turned a blind eye. Storm’s lawyers, meanwhile, have argued that he was simply a developer of open-source, decentralized software with legitimate, privacy-preserving uses who should not be held responsible for bad actors’ use of it.
“There’s certainly going to be a very vigorous defense here that they were writing code and that [Tornado Cash] was designed for privacy — that some people may have taken advantage of it, but [Storm and his colleagues] weren’t co-conspirators,” said Mark Bini, a partner in Reed Smith’s global regulatory and enforcement practice group. “Mixers have been very controversial because they’ve been used by lots of people doing bad things, no doubt about it, but the idea that some people would want to use them for privacy, that’s a legitimate argument as well. That’s going to make for a fierce battle here.”
Storm’s trial has drawn the attention of many in the crypto industry, who have raised concerns that, if Storm is found guilty, it could mean that developers down the line are on the hook for how people use their programs — something that could have devastating consequences for both the availability of privacy tools and the decentralized finance (DeFi) space as a whole. A host of major players in the industry, including investment firm Paradigm, and non-profit advocacy groups Coin Center and the DeFi Education Fund, have submitted amicus briefs in Storm’s defense.
Others, however, have been more reluctant to accept Storm’s privacy defense. Economics writer J.P. Koenig wrote in a 2024 blog post that, if Storm prevails at trial, it could “potentially mean that anyone who wants to facilitate illegal activities would have a strong incentive to copy Tornado Cash, effectively turning their operation into a ‘golem’ — a deathless artificial being run on smart contracts — and then throwing away the keys to avoid the law.”
Swiss blockchain analytics firm Global Ledger wrote in a blog post that there are, in general, “far more reasons why cyber criminals might want to use a mixing service than developers who legitimately want to obfuscate the movement of their personal funds.”
Storm’s trial begins as the U.S. government continues to overhaul its approach to the crypto industry — particuarly crypto regulation. Under U.S. President Donald Trump, the White House has taken a friendlier stance towards the industry (which poured a whopping $130 million into congressional races in the 2024 elections and at least $18 million into Trump’s inaugural committee alone), nudging regulators and law enforcement to do the same.
Since Trump took office in January, the U.S. Securities and Exchange Commission — which had taken on a bogeyman-like status under former Chair Gary Gensler for its so-called practice of “regulation by enforcement” — has formed an industry-friendly Crypto Task Force and dropped a slew of open cases and investigations into crypto companies. In an April memo to staff, Deputy Attorney General Todd Blanche ordered U.S. Department of Justice (DOJ) staff to “narrow” their focus on crypto crime, instructing them that the agency would no longer be charging regulatory violations in cases involving crypto.
Though some speculated that prosecutors would back down from their case against Storm in the wake of Blanche’s memo, the government pressed forward, dropping just one part of one charge. Prosecutors also opted to continue with their case against Storm in March after the U.S. Treasury Department’s Office of Foreign Asset Control (OFAC) delisted Tornado Cash from their list of sanctioned entities, after a federal judge ruled that the agency could not sanction a smart contract.
“Frankly, I was kind of surprised it was going forward after we saw that [Tornado Cash] was taken off the OFAC list,” Bini said. “We don’t know the government’s evidence yet, but we’ve seen the Trump Administration really move away from these sort of regulatory-type cases. And this seems like one that is on the edges of that because the conspiracy to operate an unlicensed money transmitting business [charge] does seem like the type of regulatory case that perhaps the Administration is getting out of the business of.”
During a pre-trial conference last week, District Judge Katherine Polk Failla of the Southern District of New York (SDNY) ruled that neither side could bring up the OFAC sanctions — either that Tornado Cash was sanctioned in the first place or that the sanctions were subsequently removed — during Storm’s trial, arguing that it would confuse the jury. Failla also ruled that neither party could mention the outcome of a related civil case, Van Loon vs. Department of the Treasury.
Bini told CoinDesk that Failla’s ruling to keep the OFAC sanctions out of the trial is likely to help the government’s case more than Storm’s.
If the defense was able to tell the jury that OFAC’s sanctions were later dropped, Bini said, “I think you’re more likely to have jurors say ‘gosh, I’m not sure of whether this is illegal or not.’ And if they’re not sure, well, then the defendant is not guilty. I think that ruling probably helped the government to some extent in making the case seem cleaner and less complicated.”
Bini said that, if the trial results in a conviction, Failla’s ruling presents potential grounds for Storm’s lawyers to appeal.
“The defense may say, ‘hey, we should have had the right to present that to the jury, we think that’s important evidence,’” he said. “This is the type of case where even if the government gets a conviction as they usually do, there really may be some legal infirmities.”
If the jury finds Storm guilty, Bini said that there might be another option beyond an appeal — a presidential pardon. Trump has pardoned a number of people in the crypto industry since taking office in January, including the co-founders of BitMEX and Silk Road founder Ross Ulbricht.
“Let’s say it results in a conviction, that doesn’t mean that the President might not get involved afterwards,” Bini said. “That’s a bit of a wild card that we could see play out here if the case results in a conviction.”
In a final pre-trial conference on Friday, Storm’s lawyers made a last-ditch effort to get the case dismissed after the government revealed that its theory of venue (basically, the prosecution’s justification to bring the case in the Southern District of New York) hinged on three pieces of evidence — Storm’s texts to a New York-based venture capitalist, Storm’s interview with a New York-based Bloomberg reporter and the fact that a hacker accessed Tornado Cash from New York.
Failla ultimately ruled against the defense’s motion, allowing the government’s case against Storm to proceed to trial.
Storm’s trial, initially slated for two weeks, is expected to run a full month due to the sheer number of witnesses in the case. The government alone told the court it planned to call more than 20 people to testify, including a hacker who used Tornado Cash, a so-called “victim” witness and a host of expert witnesses.
Jury selection is expected to take two days, with opening arguments likely slated for Wednesday.
Storm has not yet indicated either way whether he will testify in his own defense, but Bini said it could be a big help for his defense.
“I think there’s a really good chance [Storm] will testify. If so, [he’s] going to have to withstand some really stiff cross [examination], but that could be really powerful in a case like this,” Bini said. “The burden is on the government, not the [defense], but they might want to take the stand and tell the jury their story.”
