Dragonfly Capital may soon find itself in the crosshairs of U.S. prosecutors over its 2020 investment in Tornado Cash developer PepperSec, Inc., the firm behind the now-sanctioned crypto privacy protocol.
Key Takeaways:
- Dragonfly Capital may face legal scrutiny over its 2020 investment in Tornado Cash developer PepperSec.
- Managing partner Haseeb Qureshi defended the move, citing legal assurances.
- Tornado Cash continues to process high volumes.
The venture capital firm signaled Friday that it would push back hard if formal charges are filed.
In a statement on social media, Dragonfly managing partner Haseeb Qureshi defended the investment, stressing that it was made in good faith after receiving legal assurances of compliance.
“We made this investment because we believe in the importance of open-source privacy-preserving technology,” Qureshi wrote. He added that legal counsel at the time found no regulatory red flags.
US Crackdown on Tornado Cash Sparks Crypto Privacy Debate
The controversy stems from the US government’s crackdown on Tornado Cash, a tool that enables users to obscure the origin and destination of crypto transactions.
Though the protocol was pitched as a decentralized privacy enhancer, it became a favorite among hackers and sanctioned entities seeking to hide digital footprints.
In 2023, the Department of Justice charged developers Roman Storm and Roman Semenov with money laundering and violating U.S. sanctions.
Storm’s trial is currently underway in New York and could result in a decades-long prison sentence. On Friday, prosecutors suggested Dragonfly itself could be next.
Qureshi dismissed the notion as an intimidation tactic. “We believe the government’s statement in court today was primarily to undermine a defense of Tornado Cash,” he said. “Bringing charges now would be outrageous.”

Tornado Cash has remained a legal and ethical flashpoint in the debate over privacy and regulation in crypto.
Its sanctioning by the U.S. Treasury’s OFAC in 2022 was a landmark moment, with authorities alleging it facilitated billions in illicit transactions, including funds tied to North Korean hackers.
Despite the sanctions, Tornado Cash has shown surprising resilience. Flipside Crypto reported $1.9 billion in deposits through the platform in the first half of 2024, indicating continued demand for anonymity tools in blockchain transactions.
No Final Ruling Needed After Tornado Cash Removed from Sanctions List
In March, the US Treasury Department argued that no further court ruling is necessary in the legal battle over its sanctioning of crypto mixer Tornado Cash, citing its recent removal of the platform and associated addresses from the sanctions list.
As reported, a developer has ported Tornado Cash to the MegaETH blockchain’s public testnet, enabling private transactions on the high-performance network.
MegaETH, which recently launched, boasts a throughput capacity of up to 20,000 transactions per second.
The developer, known pseudonymously as Gunboats, said the idea was sparked by the U.S. Treasury’s recent removal of Tornado Cash addresses from the OFAC sanctions list, following a court ruling earlier this year.
