Fidelity Moves Into Ethereum Tokenization as Tornado Cash Lawsuit Takes New Turn

Tornado Cash Lawsuit: Treasury Seeks to End Case After Delisting

While traditional finance edges closer to blockchain integration, the privacy-focused side of crypto continues to battle legal headwinds. On the same day as Fidelity’s filing, the U.S. Treasury Department formally removed Tornado Cash and several associated smart contract addresses from its sanctions list—yet it now claims that no final court judgment is necessary in the ongoing lawsuit.

The Office of Foreign Assets Control (OFAC) originally blacklisted Tornado Cash in 2022, citing its alleged use by North Korea’s Lazarus Group for laundering illicit funds. A group of users, backed by Coinbase and led by Ethereum developer Preston Van Loon, sued the Treasury, arguing that the sanctions violated constitutional rights.

After months of legal back-and-forth, including a Texas court ruling partially in favor of Tornado Cash in January 2024, Treasury’s delisting was seen by some as a concession. However, Coinbase Chief Legal Officer Paul Grewal contends that the government is attempting to sidestep a full judicial review by claiming the case is now moot.

“The law is clear—removing Tornado Cash from the list doesn’t prevent the Treasury from relisting it in the future,” Grewal said, referencing Supreme Court precedent that voluntary policy reversals don’t automatically nullify lawsuits.

The legal uncertainty surrounding Tornado Cash persists, especially as its founders remain entangled in criminal proceedings. Roman Storm, one of the protocol’s co-founders, faces trial in April, while fellow founder Roman Semenov is still wanted by the FBI. Developer Alexey Pertsev, previously jailed in the Netherlands, was recently released pending appeal of a money laundering conviction.

Coinbase CLO Criticizes U.S. Treasury for Tornado Cash Sanctions

Coinbase’s Chief Legal Officer Paul Grewal has publicly criticized the U.S. Treasury for attempting to sidestep a court ruling regarding the delisting of Tornado Cash, a crypto mixer accused of laundering over $7 billion. In 2022, the Treasury blacklisted Tornado Cash after it was accused of facilitating money laundering for groups like North Korea's Lazarus hacking group.

However, after the Treasury lifted sanctions on Tornado Cash last week, the debate reignited. Grewal’s condemnation centers on the Treasury’s recent filing, which seeks to render the case moot, claiming that the issue is no longer relevant. He argued that this move undermines legal procedures and suggests that the Treasury could potentially reimpose sanctions in the future without sufficient legal resolution.

While Tornado Cash’s delisting has been seen by some as a win for the crypto community, the lack of assurances from the Treasury that it won’t be blacklisted again creates a lingering uncertainty.

Tornado Cash and Its Legal Battles

The Tornado Cash case remains a significant point of contention in the broader regulatory debate surrounding crypto mixers. Users of Tornado Cash have argued that the platform’s immutable smart contract doesn’t qualify as property under the International Emergency Economic Powers Act (IEEPA), which the Treasury invoked to impose sanctions.

While the legal proceedings continue, with some court rulings siding with Tornado Cash users, Grewal’s concerns focus on the potential for the government to reimpose sanctions without the necessary legal framework. He emphasized the ongoing risks of ambiguity surrounding the future treatment of Tornado Cash.

Coinbase, along with the Ethereum Foundation, has supported Tornado Cash in funding the legal defense of lead developer Alexey Pertsev, highlighting the continued push for clarity on the platform’s legal status.

Traditional Finance’s Embrace of Blockchain

As the debate over privacy and decentralization in crypto continues, the traditional finance sector has made significant strides in blockchain adoption. Fidelity’s tokenization of its Treasury Digital Fund demonstrates how institutions are exploring blockchain for its transparency and traceability benefits. This approach places traditional finance in direct contrast to privacy-focused crypto advocates, who are resisting regulatory pressures and pushing for more decentralized systems.

Conclusion: A Diverging Path for Blockchain

While institutions like Fidelity move forward with blockchain innovations, particularly in the realm of tokenizing real-world assets, the Tornado Cash case represents the ongoing tensions between privacy advocates, decentralization, and regulatory oversight. The legal uncertainty surrounding Tornado Cash underscores the challenges that privacy-focused crypto projects face in an increasingly regulated environment.

The future of blockchain, Web3, and crypto will likely be shaped by how these contrasting paths continue to evolve. The balance between transparency, privacy, and regulation will be crucial in determining the success and adoption of blockchain technologies across both traditional finance and the crypto space.
