Keonne Rodriguez, one of the individuals associated with the cryptocurrency mixer Samourai Wallet, who was charged with money laundering by the United States Justice Department, has entered a plea of not guilty and has been released on bail.

Appearing in the U.S. District Court for the Southern District of New York on April 29, Rodriguez pleaded not guilty to charges of conspiracy to operate an unlicensed money-transmitting business and money laundering. The Assistant U.S. Attorneys overseeing the case agreed to a $1 million bond for the Samourai Wallet co-founder, with strict travel restrictions limiting him to parts of New York and Pennsylvania when not confined to his home.

As part of his bail conditions, Rodriguez will be largely confined to his residence in Harmony, Pennsylvania, and will be required to wear a location monitoring device. Additionally, he is prohibited from performing any services for Samourai Wallet or engaging in any cryptocurrency transactions, directly or indirectly, without prior approval.

William Hill, the chief technology officer of Samourai Wallet, was also arrested on April 24, the same day as Rodriguez, but has not yet appeared in a U.S. courtroom. Hill was arrested in Portugal, and it is likely that authorities are working through extradition proceedings. Rodriguez is scheduled to appear in court again on May 14.

If convicted, both Rodriguez and Hill could face up to 20 years in prison for the money laundering charge and five years for the conspiracy to operate an unlicensed money-transmitting business charge. Authorities have already seized control of Samourai Wallet’s servers and domain in Iceland.

These arrests are part of a broader crackdown by the U.S. government on cryptocurrency mixers, which are believed to facilitate money laundering by hacker groups and terrorists. The U.S. Treasury Department’s Office of Foreign Asset Control has sanctioned Blender and Tornado Cash, despite criticism from many industry leaders and lawmakers.
