Mars Finance reports that according to Cointelegraph, in a letter to the SEC earlier this month, Citadel urged the SEC not to grant broad exemptions to DeFi platforms to trade tokenized U.S. stocks, citing that these platforms could very likely be classified as "exchanges" or "broker-dealers" regulated under securities laws. In response, cryptocurrency advocacy groups such as Andreessen Horowitz, the Uniswap Foundation, the DeFi Education Fund, and the Digital Chamber of Commerce have sent a letter back to the SEC, opposing Citadel Securities' request for the SEC to tighten regulations on tokenized stocks in the DeFi space. "Citadel's letter is based on a misinterpretation of securities law, attempting to extend the SEC's registration requirements to DeFi trading."
