The U.S. Treasury has issued a letter to Binance, urging the cryptocurrency exchange to adhere to a government-mandated compliance monitoring program. This includes the timely submission of data records and documents, as well as cooperation with interviews involving key executives. The move follows reports of over $1 billion in crypto assets allegedly flowing through Binance to entities linked to Iran. The letter specifically requests information on executives such as Chief Compliance Officer Noah Perlman, Global Sanctions Head Astra Cai, and Jukai "Rock" He, along with details on former employees. Binance is also required to maintain regular monthly meetings with FinCEN and designated monitors.
