Odaily Planet Daily News - The founding team lawyers of the cryptocurrency mixer Samourai Wallet submitted documents to the Manhattan federal court, accusing the prosecution of concealing key regulatory opinions for up to 18 months. The documents show that the U.S. Department of the Treasury's Financial Crimes Enforcement Network (FinCEN) informed the prosecution as early as November 2023 that, because Samourai does not host user private keys, its services 'do not meet the money service business (MSB) licensing requirements.' However, the prosecution still charged the two founders in April 2024 with operating without a license and money laundering, involving $2 billion in illegal transactions. The lawyers pointed out that the prosecution should have disclosed this information by May 8, 2023, but did not make it public until April 1, 2025. FinCEN officials acknowledged in internal communications that the existing regulatory guidelines do not clearly define the criteria for 'functional control' of cryptocurrencies, and the prosecution's arguments carry legal risks. The Samourai team plans to apply again to dismiss the charges based on this and questions the Department of Justice's breach of its April policy direction of 'not pursuing unintentional violations by mixers.' This case may become an important precedent for the transparency of cryptocurrency regulatory enforcement. (Cointelegraph)
