Samourai Wallet Co-Founder William Hill Sentenced to Four Years in Federal Prison

Highlights:

• William Hill has received a four-year sentence as the court stresses strict action on crypto tools.
• The case of the Samourai Wallet co-founder highlights the rising tension between privacy tech and enforcement goals.
• Hill’s sentence shows the rising focus on crypto mixers as advocates push for protection for software developers.

The federal court in New York sentenced Samourai wallet co-founder William Hill to four years in prison on Wednesday after his guilty plea in July. The court handled this case shortly after it sentenced his former colleague, Keonne Rodriguez, to five years. Both men admitted involvement in the operation of an unlicensed money-transmitting business. Prosecutors stated that the service moved significant criminal proceeds and helped users hide those funds.

The court also required Hill and Rodriguez to serve three years of supervised release. Both men must pay a $250,000 fine each. They already paid more than $6.3 million in forfeitures. Prosecutors said the platform handled funds linked to darknet markets and other crimes. They also said the pair built tools that appealed to people seeking privacy for illegal transfers.

The case drew attention because of the scale of the activity. Court documents said the platform’s mixing features formed an end-to-end laundering chain. Prosecutors argued that the tools helped users mask the origin of at least $237 million. Officials said the case highlighted the use of crypto mixers in broader criminal networks. They also said the conduct involved efforts to avoid oversight.

The sentence marked a key point in a case that began when both men denied wrongdoing last year. However, they shifted their positions and accepted the charges in July. The judge said the sentence reflected the seriousness of their actions. The court aimed to send a clear message about the consequences for laundering known criminal proceeds.

William Hill Receives Reduced Sentence After Judge Reviews Mitigating Factors

Judge Denise Cote reviewed several mitigating factors before she delivered Hill’s sentence. She noted his advanced age and a recent autism diagnosis, and she said those factors influenced her assessment. She said she would have imposed a longer term without those elements. Judge Denise emphasized that Hill would face greater difficulty in prison due to those circumstances.

Hill’s lawyer described the diagnosis as an essential part of the case. He said it explained Hill’s decision-making and his rigid interpretation of rules. He said Hill believed he operated within a protected space because the service did not maintain custody of user funds. The lawyer also said Hill held an idealistic view of blockchain technology. The lawyer argued that Hill viewed the project as a pushback against government control.

The judge questioned parts of the defense argument. She wanted to know whether Hill understood the moral issues involved. She said that no diagnosis removed the difference between right and wrong. The judge also said no legal misunderstanding excused the conduct. She asked Hill to explain his decisions directly to the court.

Hill addressed the court and expressed remorse. He said the case caused severe stress for his family. Hill said he misjudged his actions and used misguided beliefs to justify his work. He said he learned an important lesson from the experience. He accepted responsibility and said he understood the consequences.

Federal Scrutiny of Crypto Mixing Platforms Continues

Prosecutors continue to target crypto mixing services because they see these tools in major criminal schemes. They have brought several cases against developers who created privacy systems that help users hide funds. Tornado Cash developer Roman Storm faced charges that included money laundering and conspiracy to run an unlicensed money-transmitting business. A jury later reached a mixed outcome. It found him guilty on the money-transmitting charge, but could not agree on the money laundering and sanctions charges.

The case drew reactions across the digital asset community. Advocates said the charges raised questions about how prosecutors view software development. They organized fundraisers to support Storm’s legal efforts. They also urged lawmakers to protect developers as they debate digital asset rules. In August, Justice Department official Matthew J. Galeotti addressed these concerns directly. He said that writing code does not amount to a crime.

Storm’s case continues to shape the broader discussion about privacy-focused tools. It also adds pressure on policymakers to clarify the limits of development.
