According to the source, a Grayscale ETF tracking XRP (XRP), Solana (SOL), and Cardano (ADA) is expected to list on a U.S. exchange after an SEC pause, but traders should only act once an SEC-approved 19b-4 for the listing venue and an effective S-1 appear on EDGAR. Source: U.S. Securities and Exchange Commission; SEC EDGAR. Key trading checkpoints are the SEC approval order on the exchange’s 19b-4 docket, the issuer’s S-1 effectiveness on EDGAR, and an exchange listing notice with ticker and first-trade date, as these filings govern launch timing and feasibility.

Until those filings are public, an ETF cannot legally launch in the U.S., so headline-driven positions should be deferred in favor of monitoring the official dockets.
