The Blockchain Association, Coin Center, and DeFi Education Fund have recently filed court documents arguing that Tornado Cash, a cryptocurrency mixer, did not have control over the funds or messages sent by users. In addition, these advocacy groups have stated that the three felony charges against Roman, the co-founder of Tornado Cash, should be dropped. They cite First Amendment concerns related to allegations of violating sanctions and claim that the U.S. government has a misunderstanding of the relationship between smart contract protocols and their developers in regards to money laundering accusations.

Crypto advocacy groups caution about potential negative consequences for the cryptocurrency sector in legal proceedings against the co-founder of Tornado Cash.
