According to X user @SummersThings, Form 19b-4 of the VanEck and 21Shares Solana ETFs appears to have been removed from the CBOE website. The files SR-CboeBZX-2024-066 and SR-CboeBZX-2024-067 can no longer be accessed through direct links, and are no longer visible in BZX Pending Rule Changes. It added: "Another interesting thing is that both applications were filed on July 8, but the SEC never issued Notices of Filing for them. Does this mean that 19b-4 was withdrawn?"
