Current U.S. sanctions fact: On March 21, 2025, the U.S. Treasury announced that it had removed economic sanctions against Tornado Cash. This is not a universal declaration that every transaction is lawful.
What changed
The delisting followed litigation over whether immutable smart contracts were sanctionable property under the applicable statute. Treasury said it remained concerned about malicious actors, including DPRK-linked activity, and would continue enforcement against illicit conduct.
What did not automatically change
Developer prosecutions, anti-money-laundering rules, exchange risk policies, civil liability, and the laws of countries outside the United States are separate questions. A protocol’s technical availability does not determine the legality of a particular person’s conduct.
