According to the source, the SEC has approved the Hashdex Nasdaq Crypto Index US ETF to operate under new generic listing standards, allowing holdings beyond BTC and ETH to include XRP, SOL, and XLM (source: the source). Traders should confirm via the official SEC order posted on sec.gov and any Hashdex prospectus supplement or 8-K detailing eligible assets and implementation timelines before positioning (source: SEC; Hashdex). Monitor the ETF’s effective date, daily holdings, and creation unit basket disclosures to assess potential buying needs and rebalance timing once the change is in force (source: SEC; Hashdex). Until an SEC order or issuer filing is available, treat the claim as unconfirmed and track spreads, liquidity, and volume in XRP, SOL, and XLM during U.S. hours for signs of ETF-related flow (source: the source; SEC).
