Several major financial firms are pushing forward with proposals for the next alternative coin (altcoin) exchange-traded fund (ETF), aiming to bring Solana’s assets to U.S. markets. This is part of a trend where issuers have made multiple amendments to their filings this week, following similar updates on XRP ETF applications last week. The focus has been on improving redemption mechanics, allowing for either cash or direct Solana-based redemptions, a feature that may entice institutional investors. 21Shares, Grayscale, Fidelity, and other established firms are all part of this push, signaling an active dialogue with regulators regarding the SEC’s approval process. The only currently live Solana ETF is REX-Osprey SOL + Staking, but its limited inflows compared to successful Bitcoin and Ethereum ETFs suggest room for more growth.
