Answer
Mixer Sanctions and Cases
Designations are documentable: a specific authority, a specific date, a specific document. This page covers how a mixer moves from tool to sanctioned service — and the record a checkable case must contain.
direct answer
A mixer becomes a case only through a dated document — not through reputation.
Primary authorities referenced: US Treasury/OFAC and US Department of Justice (roots checked 2026-10-31). The one case listed below is bound to two primary OFAC documents — a designation and its removal; other cases stay unlisted until the same record exists.
What counts as evidence
Date, authority, document
A useful sanctions citation answers three questions: who designated, when, and where the document lives. A “mixers are used by criminals” statement without any of the three is an observation, not a case.
Two different things get called cases in casual use: a designation of a specific service by an authority, and a legal action against operators. Both are primary documents with dates; neither is a general statement about mixers.
Case record
What a checkable case contains
| Field | What it answers | Where to check |
|---|---|---|
| Authority | Who issued the action | The agency's own site |
| Instrument | Designation, indictment, complaint or settlement | The document itself, not a news retelling |
| Date | When it was issued, filed or took effect | The document header |
| Subject and scope | Service, operator or address — and what was not designated | The named parties and scope in the document |
| Current status | Whether it is still in force, delisted or vacated | The authority's current list or docket |
Bound case
One designation, and its removal
| Case | Authority · instrument | Date | Record | Primary document |
|---|---|---|---|---|
| Tornado Cash (service) | US Treasury / OFAC · SDN designation | 2022-08-08 | Added to the SDN List | ofac.treasury.gov/recent-actions/20220808 |
| Tornado Cash (service) | US Treasury / OFAC · SDN removal | 2025-03-21 | Deleted from the SDN List | ofac.treasury.gov/recent-actions/20250321 |
Why both rows
A case has a current status
Two dated OFAC documents describe Tornado Cash: designation on 2022-08-08 (Treasury release jy0916) and removal from the SDN List on 2025-03-21. Read together they show why “current status” is a required field — a page that stopped at 2022 would describe the service wrongly today.
The removal document records only the change to the SDN List. It says nothing about other authorities, civil claims, or the conduct described in the designation. Neither document is a statement about mixers as a class.
