The U.S. SEC has accepted Grayscale's application for the Solana ETF (19b-4) and started soliciting public comments yesterday. At the same time, the SEC also conducted a public comment solicitation for the LTC ETF application submitted by Canary a week ago.

Based on the current progress, LTC is the fastest among all altcoin ETFs in the application process and is likely to become the first altcoin ETF approved by the SEC.
