According to the source, there is a claim that Solana (SOL), Litecoin (LTC) and Hedera (HBAR) ETFs will begin trading this week, but this cannot be verified without official issuer, exchange, or regulator documentation. Please provide an official exchange listing notice (e.g., NYSE, Nasdaq, Cboe, TSX, SIX, Xetra, HKEX), a regulator approval or filing (e.g., SEC, OSC, FINMA, BaFin, SFC), or an issuer press release with tickers and fees so a compliant, trading-oriented summary with precise sources can be produced.
