CoinDesk reported that the Securities Transfer Association (STA), an industry organization for U.S. security transfer agents, sent a letter to the SEC urging that future rules for tokenized securities prioritize tokenized stocks authorized by public companies and recorded in official shareholder registers, rather than stock tokens issued by third-party platforms. STA believes that third-party stock tokens could expose investors to platform, custody, and counterparty risks, and weaken shareholder rights.
