The strongest usable evidence in this run is the PANews article '美国SOL现货ETF单日净流入1303.63万美元 | PANews', which directly matches the claim's key figures: $13.0363 million in daily net inflows on April 17, Bitwise Solana Staking ETF leading inflows, and total net assets of $903 million. That article explicitly cites SoSoValue as its source. However, the primary SoSoValue page at https://sosovalue.com/etf/us-sol could not be fetched, and the supplied Odaily and X links were not retrievable. Because the main numeric details are consistent in the validated PANews report but primary-source confirmation was unsuccessful in this run, the statement is best assessed as likely true rather than confirmed with high confidence.
