Could you please elaborate on why MetaMask doesn't currently support Solana? As a popular cryptocurrency wallet, it seems like a natural fit for users to be able to store and manage their
Solana assets. Are there any technical challenges or limitations that are preventing MetaMask from integrating Solana support? Alternatively, are there any plans in the near future to add Solana support to MetaMask, and if so, what can users expect in terms of functionality and security?
