Tornado Cash Sanctions Overturned by U.S. Appeals Court; TORN Soars Over 500%

U.S. sanctions against Tornado Cash, a service that anonymizes crypto transactions, must be abandoned, a federal appeals court ruled Tuesday.

The decision answers a controversial privacy debate on whether the government — via a sanctions list maintained by the U.S. Treasury Department — has a right to target the technology because it’s associated with criminals. The ruling reversed a district court’s August ruling that had sided with the government’s pursuit of what it had characterized as a “notorious” crypto-mixing service.

“Tornado Cash’s immutable smart contracts (the lines of privacy-enabling software code) are not the ‘property’ of a foreign national or entity,” according to a U.S. Court of Appeals for the 5th Circuit ruling, so they can’t be blocked under the International Emergency Economic Powers Act, and the Treasury’s Office of Foreign Assets Control “overstepped its congressionally defined authority” when it did so.

OFAC had sanctioned Tornado Cash last year, contending that it was a vital tool used by bad actors including North Korea’s Lazarus Group to launder crypto tokens pilfered from platforms and games such as Axie Infinity.

Coinbase Inc. (COIN) and others had sued the government, claiming it had overreached. Paul Grewal, chief legal officer of crypto exchange Coinbase, cheered the ruling in a Tuesday post on X, calling it a “historic win for crypto.”

“These smart contracts must now be removed from the sanctions list and U.S. persons will once again be allowed to use this privacy-protecting protocol,” Grewal wrote. “Put another way, the government’s overreach will not stand.”

The circuit court recognized the difficulty of this situation.

“We readily recognize the real-world downsides of certain uncontrollable technology falling outside of OFAC’s sanctioning authority,” the judges said, referencing the ineffectiveness of a law that was established well before the world moved online. “But we must uphold the statutory bargain struck (or mis-struck) by Congress, not tinker with it.”

In the hours following the ruling, Tornado Cash’s TORN token rallied over 500%, according to CoinGecko data, passing the $20 mark. TORN dropped from this price range to below $8 in mid-2022 as its founders faced legal challenges and the U.S. Department of the Treasury sanctioned the protocol, which blocked its use on most major centralized crypto exchanges.
