The Chicago Board Options Exchange (Cboe) has confirmed that two asset managers, VanEck and 21Shares, plan to launch exchange-traded funds (ETFs) based on Solana. The options exchange filed a 19b-4 filing with the Securities Exchange Commission (SEC) on Monday to list potential spot Solana ETFs for VanEck and 21Shares. Once the SEC confirms receipt of the document, the regulator will have 240 days to approve or reject the product.
