Samourai Wallet Co‑Founder Sentenced to Five Years for Unlicensed Money Transmitting

In a major enforcement action against a privacy‑centric Bitcoin tool, Keonne Rodriguez, a co‑founder of Samourai Wallet, was sentenced on 6 November 2025 to 60 months (five years) in prison, fined $250,000 and ordered to serve three years of supervised release afterward. 

Rodriguez pleaded guilty in July 2025 to one count of conspiracy to operate an unlicensed money transmitting business, under 18 U.S.C. § 1960(b)(1)(C), in connection with his role in Samourai Wallet’s services.  The charge carries a statutory maximum sentence of five years, and the judge imposed the full term at the request of prosecutors. 

According to the United States Attorney’s Office for the Southern District of New York, Samourai Wallet and its founders built tools (notably the “Whirlpool” coin‑mixing feature and “Ricochet” hops) that enabled the laundering of crime proceeds through Bitcoin transactions. Prosecutors allege the wallet transmitted more than $200 million in illicit proceeds and facilitated mixing for funds derived from darknet markets, hacks, fraud and sanctions‑evasion. During sentencing the judge criticised Rodriguez’s argument that his motive was privacy protection, stating that his work enabled criminal actors and lacked acknowledgement of the “human suffering” involved. 

The case holds broader significance for the Bitcoin community and developers of privacy‑tools. The government’s successful use of money‑transmitting statutes against software authors suggests that mere development of non‑custodial software might carry legal risk, depending on the facts. Some privacy advocates argue the case may chill development of open‑source tools that enable financial privacy. On the flip side regulators and law‑enforcement view the decision as a clear signal: the use or marketing of tools knowingly facilitating illicit proceeds can remove the shield of open‑source or decentralised development.

The sentencing closes a chapter for Rodriguez but opens a broader debate around how jurisdictions will treat software that enhances financial privacy — especially in the Bitcoin space. For participants in the ecosystem the message is clear: privacy tools designed (or used) for illicit flows may trigger full criminal liability, regardless of underlying technology.
