The SEC has expressed concerns regarding REX Shares and Osprey Funds' proposal to launch staking exchange-traded funds (ETFs) for Ethereum and Solana. The agency highlighted unresolved legal qualifications for the ETFs and requested a delay in their registration statement until these issues are addressed.

The SEC's recent ruling that certain liquid staking activities fall outside securities laws is seen as a significant development for institutional investors, allowing them to earn staking rewards while keeping access to their capital. This regulatory clarification is expected to encourage more institutional participation in the crypto space, particularly with Ethereum-based liquid staking protocols.

The SEC has approved Grayscale's Digital Large Cap Fund, which is primarily composed of Bitcoin and Ethereum, potentially paving the way for more cryptocurrency ETFs. This decision reflects a more favorable regulatory environment for crypto assets, with the SEC also exploring various other ETF proposals.

Nasdaq has submitted a filing to the SEC to incorporate staking into BlackRock's iShares Ethereum Trust (ETHA). This move follows significant inflows into Ethereum ETFs, with BlackRock's fund alone receiving $499 million recently. Staking is expected to enhance returns and efficiency for investors in the trust.
