On January 29, COINOTAG reported that Cboe BZX has taken a significant step by submitting a fresh batch of applications targeting the launch of a **spot Solana exchange-traded fund (ETF)**. The exchange recently filed 19b-4 documents for several notable products, including the **Canary Solana Trust**, **Bitwise Solana ETF**, **21Shares Core Solana ETF**, and the **VanEck Solana Trust**. The 19b-4 filing serves as a critical mechanism for exchanges to propose new products, marking the beginning of the approval journey once green-lit by the **SEC** and published in the **Federal Register**. Notably, these recent applications come on the heels of last year’s **rejections**, reflecting an evolving regulatory landscape for cryptocurrency-based investment vehicles.
