The news comes amid ongoing uncertainty over Tornado Cash and other cryptocurrency mixers after the mixer was restricted by United States authorities. The US Treasury Department’s Office of Foreign Assets Control blacklisted Tornado Cash in August 2022, making it illegal for citizens, residents, and businesses to receive or send money through the service.
In October, cryptocurrency advocacy group Coin Center filed a complaint against OFAC, Treasury Secretary Janet Yellen, and OFAC Director Andrea Gacki, alleging that the Tornado Cash sanction was “unconscionable and illegal.” .
