PANews reported on March 27 that according to Decrypt, 34 crypto companies and foundations including Coinbase, Kraken, and Uniswap Labs jointly wrote to the U.S. Congress, requesting clarification of the Department of Justice's broad interpretation of the definition of "fund transmitter" in Section 1960 of the Criminal Law, saying it threatens the development of non-custodial software in the United States. This provision was used to accuse Tornado Cash co-founder Roman Storm, causing industry concerns. The DeFi Education Fund stated that the current practice may convict ordinary developers, and called on Congress to clarify the legislative intent and avoid the trend of "replacing regulations with criminal penalties" in law enforcement.
