The Oregon attorney general has sued Coinbase, accusing it of violating state securities laws by illegally offering and selling assets designated as "crypto securities" to Oregon residents, a total of 31 tokens, far more than the number mentioned in previous SEC cases, including AAVE, UNI, LINK, MKR, FLOW, XRP, etc. The document claims that Coinbase has long avoided regulatory obligations and assisted in the sale of unregistered securities. The lawsuit is currently based on state law rather than federal law, representing a new trend of state-level pressure on crypto platforms.
