Odaily News The U.S. Securities and Exchange Commission (SEC) opened a 21-day public comment period for the Canary Solana ETF, a proposed ETF that would bring SOL investing to mainstream finance, in a regulatory filing on Tuesday. The filing is equivalent to setting a timeline for Canary Capital's proposed investment vehicle. Within 21 days, the SEC will make a ruling (approval or rejection) or extend the deadline to postpone the decision. Crypto market observers are generally optimistic about the approval of SOL and other altcoin ETFs in 2025, but the specific timing and sequence are unclear.
