币界网报道：The U.S. Securities and Exchange Commission (SEC) has delayed its decision on the proposed Solana Staking ETF by REX Shares, pushing the deadline to March 2024. The ETF, which would offer exposure to Solana (SOL) staking rewards, was initially filed in September 2023 under the name "REX Solana Staking ETF." The SEC cited the need for additional time to review the proposal, particularly concerning investor protection and market integrity concerns. REX Shares, known for innovative financial products, aims to provide institutional and retail investors with a regulated way to earn staking yields without directly holding SOL. The delay follows heightened regulatory scrutiny of crypto-related investment vehicles, including spot Bitcoin ETFs, which recently gained approval after years of deliberation. Industry analysts suggest the postponement reflects the SEC's cautious approach toward altcoin-based products, given Solana's classification as a potential security in previous SEC lawsuits. Market reaction has been muted, with SOL prices remaining stable amid broader crypto market fluctuations. If approved, the ETF could set a precedent for similar staking-based products, further integrating proof-of-stake cryptocurrencies into traditional finance. REX Shares has not yet commented on the delay but remains optimistic about eventual approval. The decision now hinges on the SEC's evaluation of Solana's regulatory status and the ETF's compliance framework.
