Bitwise, a prominent crypto asset manager, has filed for a spot Solana ($SOL) exchange-traded fund (ETF) in Delaware, signaling a potential S-1 registration with the U.S. SEC. This move follows Bitwise's previous launches of Bitcoin and Ether ETFs. The $SOL ETF aims to provide traditional investors exposure to Solana, a major cryptocurrency. Despite the SEC's current stance labeling $SOL as an unregistered security, changes in the regulatory environment are anticipated with the upcoming U.S. presidential administration, which may influence the approval of such ETFs.
