DOJ confirms Dragonfly not under investigation in Tornado Cash case

The US Department of Justice (DOJ) has officially clarified that Dragonfly Ventures is not under investigation for its 2020 investment in PepperSec, the company that developed Tornado Cash.

The update came during the high-profile criminal trial of Roman Storm, co-founder of the cryptocurrency mixing protocol, and marks a pivotal moment in the case that has broader implications for blockchain privacy, open-source software, and legal uncertainty in the crypto space.

Dragonfly’s name surfaced last week when US prosecutors suggested in court that the venture firm could face future scrutiny due to its ties with Tornado Cash.

However, that suggestion was retracted on Monday after pushback from Dragonfly general partner Haseeb Qureshi, who posted on X that the DOJ had walked back its statement and acknowledged that “neither Dragonfly nor any of its principals are targets in their investigation”.

DOJ backtracks after trial transcript reveals misstep

Qureshi posted an excerpt from the court transcript on X to highlight the reversal.

In the exchange, DOJ representatives admitted that earlier reports linking Dragonfly to an active investigation were “wrong and misleading”.

The correction follows media speculation around whether investors like Dragonfly could become collateral targets in broader regulatory actions against Tornado Cash and its creators.

According to Qureshi, the original remarks made in open court last Friday were “unprecedented” and ran counter to DOJ policy, which prohibits prosecutors from speculating about third-party charges in front of media.

He argued the reference may have been a tactic to dissuade Dragonfly from providing testimony in support of Storm’s defence.

The incident has sparked fresh debate around the legal risks faced by early-stage crypto investors and the chilling effect such speculation could have on blockchain innovation, especially in areas involving privacy tools.

Spotlight returns to Roman Storm’s crypto trial

With Dragonfly cleared, focus has now returned to the case against Roman Storm. The defence has argued that Storm was involved in building a privacy-focused protocol, not a tool for criminal activity.

They say the protocol was immutable and could not be controlled or altered by its developers, even if bad actors misused it.

Storm’s legal team called expert witness Dr Matthew Green, a Johns Hopkins cryptography professor, who explained Tornado Cash’s use cases in protecting crypto users from scams and theft.

The team argued that privacy in crypto is not inherently criminal, but necessary for user protection.

Storm has opted not to testify in the case. The trial is now moving toward closing arguments, with a verdict expected soon.

The outcome could have long-term consequences for open-source development and the interpretation of intent in crypto protocol design.

Legal defence seeks $1.5 million as costs mount

As the trial nears its conclusion, Storm has issued an appeal for an additional $1.5 million in donations to meet ongoing legal costs.

His case has drawn widespread attention across the cryptocurrency industry, particularly among privacy advocates and software developers concerned about being held liable for how their code is used.

The DOJ’s walk-back on Dragonfly’s involvement may help shift the narrative back to the core question at the heart of the trial: whether Tornado Cash was a neutral technology or a facilitator of illicit finance.

The jury’s decision will likely set precedent for how US courts treat open-source blockchain protocols moving forward.
