The U.S. authorities are increasingly taking actions against big-name crypto mixers for potential violations of sanctions regulations. On November 29, 2023, the U.S. Department of Treasury’s Office of Foreign Assets Control (“OFAC”) sanctioned Sinbad.io (“Sinbad”), which is a virtual currency mixer. As a result, U.S. persons are generally prohibited from dealings involving Sinbad or its property interests. Virtual currency mixers are anonymized software tools that allow users to conceal the source or owner of digital assets.
