“We saw that as a much bigger problem. It sets a dangerous precedent — if this code can be established without legal boundaries, any technology, tool, or system could be fair game,” Coinbase’s Chief Legal Officer said. Paul Grewal, said CNBC.

In August, the US Treasury sanctioned the Ether-based ETH/USD Coin Mixer for its alleged role in helping hackers launder stolen cryptocurrency. OFAC claimed the service was used to launder over $7 billion worth of digital assets, of which $455 million was laundered by North Korean support Lazarus group by hackers.

Grewal likened Tornado Cash’s sanctioning to police banning all use of a freeway while chasing armed robbers down it. He said Coinbase intends to pay plaintiffs’ attorneys and other legal fees.
