This prosecutorial stance coincides with the U.S. Treasury's decision to formally withdraw the 2020 unhosted wallet rule and a 2023 proposal on mixers. The Financial Crimes Enforcement Network (FinCEN) had sought to mandate identity checks for transfers above $10,000 and recordkeeping for those above $3,000. Treasury dropped the rules, acknowledging that lawful users may utilize mixers for privacy and that the 2023 proposal could have a chilling effect on legitimate activity.
