A federal court has approved a class-action lawsuit against Solana Labs, Pump.fun, and associated projects, alleging market manipulation in the memecoin sector. The lawsuit claims that the network facilitated insider trading advantages, with the top 10 holders controlling 70% of PUMP's supply, potentially disadvantaging retail investors. This legal action could have significant implications for Solana's ecosystem and raises concerns about compliance with Countering the Financing of Terrorism regulations in decentralized trading platforms.
