The SEC has requested the withdrawal of applications for altcoin spot ETFs, including XRP, ADA, DOGE, and SOL. Here's what you need to know. The U.S. Securities and Exchange Commission (SEC) has made a significant change to its cryptocurrency-based spot ETF applications. According to Fox Business reporter Eleanor Terrett, the SEC has requested that issuers of spot ETFs for Litecoin (LTC), Ripple (XRP), Solana (SOL), Cardano (ADA), and Dogecoin (DOGE) withdraw their existing 19b-4 filings. This development is linked to the recently approved “general listing standards,” which will eliminate the need for separate filings for each fund.
