The U.S. Securities and Exchange Commission (SEC) has asked issuers of proposed ETFs tied to XRP, Litecoin, Solana, Cardano, and Dogecoin to withdraw their 19b-4 filings. This request follows the approval of new “generic listing standards” that remove the need for individual 19b-4 forms. Instead, the streamlined framework allows exchanges to list crypto ETFs under the same umbrella rules, provided the tokens meet existing criteria.
