Crypto developer Michael Lewellen, a member of Coin Center, has filed a lawsuit against US Attorney General Merrick Garland, seeking a ruling that his non-custodial crypto software, Pharos, is legal and to prevent any future prosecution. Lewellen's lawyers argue that the Department of Justice's interpretation of money-transmitting laws extends beyond the limits of the Constitution, violating the First and Fifth Amendments. Coin Center is supporting the suit, which comes amid heightened concern in the crypto industry over the prosecution of software developers. Lewellen has asked the court to declare that his business does not violate money-transmitting laws and to block the DOJ from using those laws to prosecute him.
