According to Cointelegraph, two users filed a class action lawsuit in the U.S. Federal Court of Florida, accusing the NFT trading platform OpenSea of ​​selling unregistered securities contracts. The plaintiff stated that the NFTs (including the Bored Ape Yacht Club series) purchased on OpenSea were "worthless" due to their "illegal nature." The plaintiff cited the U.S. Securities and Exchange Commission (SEC) Wells notice disclosed by OpenSea last month as an argument, indicating that OpenSea may face legal liability for promoting unregistered securities transactions.
