What prompted the U.S. Treasury’s decision to remove Tornado Cash from the sanctions list? How has Coinbase’s Chief Legal Officer responded to the Treasury’s assertion that the matter is moot? What key legal doctrine did Paul Grewal reference to support his argument? What were some of the outcomes of the legal challenges faced by Tornado Cash and its founders? How did the recent developments in Tornado Cash’s legal status influence its functionality on other blockchain networks?
The U.S. Treasury Department has 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. Tornado Cash was blacklisted in August 2022 by the Treasury’s Office of Foreign Assets Control (OFAC), which claimed the protocol was used by North Korea’s Lazarus Group to launder stolen cryptocurrency. The move sparked backlash, prompting six Tornado Cash users, including Ethereum developer Preston Van Loon and supported by Coinbase, to sue the department, claiming the sanctions were unlawful.
U.S. Treasury Delists Tornado Cash and Smart Contracts from Sanctions List
On March 21, the Treasury officially delisted Tornado Cash and several of its smart contract addresses from the Specially Designated Nationals (SDN) list. In a court filing, the department stated, “this matter is now moot,” asserting that a final judgment is unnecessary since the issue has been resolved. However, Coinbase’s Chief Legal Officer, Paul Grewal, pushed back. He argued that simply removing Tornado Cash from the list does not legally end the case. Grewal cited the “voluntary cessation” doctrine, which holds that a case is not moot if the defendant could potentially return to the same conduct. He referred to a 2024 Supreme Court decision in the case of Yonas Fikre, where a removal from the No Fly List did not invalidate a legal complaint due to the possibility of reinstatement. “Here, Treasury has likewise removed the Tornado Cash entities from the SDN, but has provided no assurance that it will not re-list Tornado Cash again,” Grewal stated, vowing to raise this with the district court.
The legal saga has seen mixed rulings. A Texas judge initially sided with the Treasury in 2023, but a later appeals court found that sanctioning the mixer’s immutable smart contracts was unlawful. That led to the sanctions being formally overturned in January 2025. While the sanctions may be lifted, legal troubles persist for the platform’s founders. Roman Storm, charged with laundering over $1 billion, awaits trial in April. Co-founder Roman Semenov remains at large, and developer Alexey Pertsev has been released in the Netherlands while appealing his conviction.
Developer Ports Tornado Cash Protocol to MegaETH Testnet After OFAC Sanctions Removal
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.

Title: U.S. Treasury: No Final Ruling Needed After Tornado Cash Removed from Sanctions List
In an era where cryptocurrency has made waves across financial markets, regulatory bodies are increasingly grappling with the complexities that come with it. The U.S. Treasury’s recent decision to remove Tornado Cash from its sanctions list marks a significant moment in the ongoing discourse surrounding cryptocurrency regulation, privacy, and the balance between innovation and security.
The Tornado Cash Controversy
Tornado Cash, the Ethereum-based privacy tool, allows users to obfuscate the origins and destinations of their cryptocurrency transactions. It quickly became a focal point for discussions about privacy in the world of digital assets. In August 2022, the U.S. Treasury sanctioned Tornado Cash, accusing it of facilitating money laundering for various illicit activities, including those connected to North Korea’s hacking groups.
This sanction drew sharp criticism from various stakeholders within the cryptocurrency community, civil rights organizations, and even some policymakers. Critics argued that the decision contradicted the fundamental ethos of decentralization and privacy that cryptocurrencies embody. Furthermore, the ban raised significant legal and ethical questions about the sweeping nature of sanctions applied to code and software, which many viewed as an overreach of governmental authority.
Legal Challenges and Community Response
In the face of the sanctions, members of the crypto community rallied around Tornado Cash. The developers, users, and advocates for privacy rights insisted that the tool itself was not illegal and argued that punishing a protocol was tantamount to stifling innovation. Several legal challenges were mounted against the U.S. government, arguing that the sanctions violated First Amendment rights by effectively censoring a form of speech.
The debate over Tornado Cash highlighted a critical concern: how to ensure that tools designed for privacy are not misused by bad actors without impeding the rights of legitimate users. The complexities of this issue are compounded by the fast-evolving nature of technology, where legislation often lags behind innovation.
The Recent Reversal
In a surprising turn of events, the U.S. Treasury announced that it would be removing Tornado Cash from the sanctions list. This decision reflects a significant shift in the regulatory landscape surrounding cryptocurrency and privacy software. The Treasury cited a combination of factors, including ongoing community advocacy, two years of legal challenges, and a growing understanding of the importance of privacy in the digital world.
By rescinding the sanctions, the U.S. Treasury has not only acknowledged the problematic nature of sanctioning a software protocol but has also opened the door for more nuanced regulatory approaches to digital privacy tools. This decision aligns more closely with the views of many in the cryptocurrency community, who argue that privacy should be preserved as a fundamental right in the digital age.
Implications for Cryptocurrencies and Privacy Tools
The withdrawal of sanctions against Tornado Cash brings relief to many in the cryptocurrency ecosystem. It allows developers and users to engage with privacy tools without the looming threat of sanctions, which can have severe legal and financial ramifications. Moreover, this indicates that regulators may be recognizing the need to separate the technology from the actions of miscreants who misuse it for illicit activities.
Moving forward, this event could set a precedent for how similar technologies are treated. The ruling serves as a case study illustrating the importance of balanced regulation that fosters innovation while also ensuring compliance with laws aimed at preventing financial crimes.
As privacy-focused tools continue to emerge, the challenge will be to create a regulatory environment that allows for innovation without losing sight of national security and anti-money laundering goals. The regulators now face the complex task of constructing a framework wherein privacy technologies can exist without being exploited by those with nefarious intents.
Looking Ahead
The implications of the U.S. Treasury’s recent ruling extend beyond Tornado Cash itself. As we forge ahead into an increasingly digital and decentralized financial landscape, this case may herald a new chapter in how cryptocurrency regulations are crafted. With rapid advancements in technology, regulators are tasked with the dual mandate of fostering innovation and ensuring security.
Seeing a prominent case such as Tornado Cash challenging and reshaping regulation can be a beacon of hope for privacy advocates. It signifies the potential for a more thoughtful approach to governance—one that acknowledges the complexity of digital finance while respecting individual rights. However, the journey forward will necessitate ongoing dialogue among regulators, industry stakeholders, and civil liberties advocates.
In conclusion, while the removal of Tornado Cash from the sanctions list represents a significant victory for privacy advocates, it also underscores the need for careful, considered policymaking that balances freedom and security in the realm of cryptocurrencies. As new technologies emerge, how regulators respond will dictate the future of the cryptocurrency landscape in the United States and beyond.
The U.S. Treasury Department has indicated that it does not require a final ruling concerning the removal of Tornado Cash from the sanctions list. This decision may have implications for regulatory clarity in the cryptocurrency space. Tornado Cash, a decentralized mixing service, had been sanctioned due to concerns about facilitating money laundering and other illegal activities.
The clarification from the Treasury could signal a shift in how similar entities are treated under U.S. law, particularly as regulations around cryptocurrency and digital finance continue to evolve. Stakeholders within the crypto community may find this development significant, as it could influence future compliance and operational protocols for services offering privacy and anonymity in transactions.
Developers and users of decentralized finance platforms will likely keep a close watch on regulatory changes and interpret how this ruling affects existing and future projects within the crypto ecosystem. The Treasury’s stance could also set a precedent for how government agencies approach decentralized technologies and their integration into the broader financial landscape.
