According to Odaily, the U.S. Securities and Exchange Commission (SEC) is urging issuers to amend and resubmit their applications for a spot Solana ETF by the end of July. This suggests that approval may come sooner than expected. Previously, the REX-Osprey SOL and Staking ETFs received automatic approval and began trading last week under different regulatory rules. This development indicates that the spot Solana ETF could join Bitcoin and Ethereum as the only approved spot cryptocurrency funds in the United States. Meanwhile, applications for XRP, Dogecoin, and Litecoin are still under review.
