DOJ Charges Samourai Wallet Founders with Money Laundering
The U.S. Department of Justice has charged the founders of Samourai Wallet, a crypto mixing service, with facilitating over $100 million in money laundering from illicit sources.

US Authorities Dismantle Samourai Wallet, Arrest Founders
In a significant move against cryptocurrency-based financial crime, the U.S. Department of Justice (DOJ) has arrested and charged the founders of Samourai Wallet, a prominent crypto mixing service. Keonne Rodriguez, the CEO, and William Lonergan Hill, the CTO, were arrested on April 24, 2024, and face charges of conspiracy to commit money laundering and conspiracy to operate an unlicensed money transmitting business.
The indictment, unsealed in the Southern District of New York, alleges that Samourai Wallet was operated as a business dedicated to obscuring the source of illicit funds. According to authorities, the service facilitated over $2 billion in unlawful transactions and laundered more than $100 million in criminal proceeds from dark web markets like Silk Road and Hydra Market, as well as from various cryptocurrency fraud schemes. The DOJ's action includes the seizure of Samourai's web servers and domain, effectively shutting down the service.
The Allegations Against Samourai Wallet
The prosecution's case centers on the argument that Rodriguez and Hill intentionally designed and marketed Samourai Wallet as a tool for criminals. The DOJ asserts that the platform went beyond providing simple privacy and operated as a for-profit, unlicensed money services business (MSB) that actively courted and catered to an illicit clientele.
Key allegations detailed in the indictment include:
* **Intentional Marketing:** Prosecutors claim the defendants openly marketed their services to those seeking to hide criminal proceeds. The indictment cites public communications and social media posts where the founders appeared to encourage obfuscating financial trails from government oversight. * **Anonymity-Enhancing Features:** The platform's core services, "Whirlpool" and "Ricochet," were designed specifically to break the on-chain link between a user's crypto deposits and withdrawals. The DOJ contends these features were not for legitimate privacy but were tools for laundering money. * **Fee-Based Business Model:** Samourai Wallet generated approximately $4.5 million in revenue by charging fees for its mixing services. This financial structure is central to the charge of operating an unlicensed money transmitting business, as it demonstrates the commercial nature of the enterprise. * **Facilitating Illicit Transactions:** The indictment explicitly states that the service was a "haven for criminals" to engage in large-scale money laundering. A significant portion of the funds processed through Samourai Wallet are traced back to sanctioned entities, ransomware gangs, and darknet marketplaces.
U.S. Attorney Damian Williams stated, "Rodriguez and Hill allegedly knowingly facilitated the laundering of over $100 million of criminal proceeds from the dark web and other computer hacking and fraud schemes. We will continue to relentlessly pursue and dismantle criminal organizations that use cryptocurrency to hide their illicit conduct."
Broader Context and Enforcement Patterns
This enforcement action is not an isolated event. It follows a clear pattern of U.S. authorities targeting cryptocurrency mixers. In August 2022, the U.S. Treasury Department's Office of Foreign Assets Control (OFAC) sanctioned the mixer Tornado Cash for its role in laundering funds stolen by the North Korean Lazarus Group. Subsequently, the DOJ charged Tornado Cash developers Roman Storm and Roman Semenov with money laundering and sanctions violations.
The Samourai Wallet case differs slightly in that it leads with charges of operating an unlicensed money transmitting business and conspiracy to commit money laundering, rather than sanctions violations. This approach underscores the DOJ's position that developing and running a mixer with the intent to facilitate illicit transactions is a criminal act in itself, irrespective of whether a sanctioned entity is involved.
Compliance Takeaway
The indictment against the Samourai Wallet founders serves as a stark warning to the digital asset industry and a critical update for compliance professionals. It reinforces the legal perspective that platforms providing financial anonymity cannot operate outside of anti-money laundering (AML) and Counter-Financing of Terrorism (CFT) regulations.
For regulated financial institutions, including virtual asset service providers (VASPs), this action necessitates immediate review and enhancement of compliance controls. Transactions associated with Samourai Wallet must be treated as extremely high-risk. Blockchain analytics tools and transaction monitoring systems should be updated to flag any direct or indirect exposure to the service. The case demonstrates that claiming to be a non-custodial software provider is not a sufficient defense when a service is designed and marketed to facilitate financial crime. Financial institutions are expected to proactively identify and report transactions that have passed through known obfuscation services as part of their AML obligations.
