The U.S. Treasury Department acted outside its authority when it sanctioned cryptocurrency mixer Tornado Cash in 2022 and accused it of helping launder over $7 billion for North Korean hackers and other malicious cyber actors,

A federal appellate court ruled that privacy tools built on the Ethereum blockchain, known as Tornado Cash, cannot be subject to the sanctions imposed by the Treasury Department. Why it matters: The ruling advances cryptocurrency law by finding that certain kinds of smart contracts are not property.

The price of TORN soared over 418% after a federal court ruled that sanctions on Tornado Cash must be abandoned.

A U.S. Appeals Court has ruled that Tornado Cash can't be blocked in the country and the Treasury Department's OFAC committed overreach when it sanctioned the crypto mixing tool.
