The well-known Ethereum mixer service Tornado Cash (TORN) will block wallet addresses sanctioned by the US Treasury Department in the future.
- Ethereum (ETH) mixer Tornado Cash (TORN) will block crypto wallet addresses that are on the US Office of Foreign Assets Control (OFAC) list in the future.
- The news comes shortly after the US Treasury Department added an Ethereum address linked to the Ronin hack to its sanctions list.
- According to the U.S. Treasury Department, this wallet address is attributed to the North Korean hacking group Lazarus.
- It would not be the first hack attributed to Lazarus. Chainalysis, a company specializing in blockchain analytics, estimates that the group captured around $400 million as early as 2021.
- Roman Semenov, co-founder of Tornado Cash, said the change is being implemented on the front end, directly at the decentralized application (dapp) level.
- Tornado Cash now also uses the Chainalysis oracle for this purpose – a smartcontract that validates whether a crypto wallet address is on the OFAC sanctions list.
- Ethereum wallet addresses blacklisted by OFAC will no longer be able to abuse Tornado Cash’s mixer for origin obfuscation in the future, according to a tweet from Tornado Cash.
