The SEC (@SECGov) has requested issuers of spot ETFs for Litecoin ($LTC), Ripple ($XRP), Solana ($SOL), Cardano ($ADA), and Dogecoin ($DOGE) to withdraw their 19b-4 applications. This is due to the recent approval of generic listing standards for commodity-based ETFs, including digital assets, which eliminate the need for individual reviews and streamline the launch process.

### Quick Context:

- **Why withdraw the 19b-4?** These applications were mandatory for exchanges (like Cboe or Nasdaq) to list the ETFs, but the new generic standards allow products that meet basic criteria (such as liquidity, history of regulated futures, and compliance) to launch directly with a simpler and faster S-1 review (around 75 days).

- **Positive impact:** It is not a rejection; on the contrary, it accelerates approvals. Issuers can proceed to launch the ETFs once the requirements are met, without waiting for case-by-case decisions. This opens the door to a "wave" of altcoin ETFs in the coming weeks or months.

- **Timeline:** Withdrawals could start this very week (late September 2025), according to sources close to the SEC. The first launches are expected for October or earlier, depending on pending S-1s.

This move follows the approval of the generic standards on September 17, 2025, and confirms a more regulatory-friendly shift towards crypto assets classified as commodities. If you need more details or real-time updates, let me know!
