The Securities Exchange Commission opened a 21-day public comment period on the Canary Solana ETF, a proposed ETF that would bring SOL investments into mainstream finance, in a regulatory filing on Tuesday. The filing amounts to setting a timeline for Canary Capital's proposed investment vehicle. Within 21 days, the Securities Exchange Commission will issue a ruling (approve or reject), or extend the deadline to delay the decision. Crypto market watchers are generally bullish on the approval of an ETF for SOL and other counterfeit products in 2025, but the exact timing and sequence is unclear.
