According to reports from Wu, Nasdaq submitted a rule change application (19b-4) to the U.S. SEC on June 2, 2024, proposing to include XRP, SOL, XLM, and ADA in the digital asset benchmark index. This proposal aims to allow the Hashdex Nasdaq Crypto Index U.S. ETF (NCIQ) to transition from the existing Nasdaq Crypto U.S. Settlement Price Index (NCIUS) to the broader Nasdaq Crypto Index (NCI). Currently, the NCI includes 9 cryptocurrencies, and if the SEC approves this application, the ETF will be permitted to invest in these coins. The SEC is expected to make a final decision by November 2, 2025.
