Is DeFi illegal in US?

Could you please clarify if decentralized finance, or DeFi, is considered illegal in the United States? As the cryptocurrency landscape continues to evolve, it's essential to stay informed about the legal status of various practices within the industry. Is there any specific legislation or guidance from regulatory bodies that outlines the legality of DeFi in the US? I'm particularly interested in understanding whether or not participating in DeFi activities, such as lending and borrowing on decentralized platforms, is permissible under current laws.
