PANews reported on March 21 that according to an announcement by the U.S. Treasury Department, OFAC (Office of Foreign Assets Control) has removed Tornado Cash and its related Ethereum addresses from the sanctions list (SDN List), ending the economic sanctions on the privacy mixing protocol since August 2022. This decision is based on the government's review of the applicability of financial sanctions in the evolving technological and legal environment.

However, the Treasury Department still emphasized that it will continue to crack down on North Korean government-sponsored hacker groups and their illegal activities using crypto assets, and remain highly vigilant about all crypto transactions that may be involved in malicious behavior.
