What are token gated features?
Could you please elaborate on the concept of "token gated features"? Could you explain what they are and how they function within the cryptocurrency and finance industry? How do these features enhance the overall security and functionality of blockchain-based projects? Furthermore, could you provide some examples of projects that have successfully implemented token gated features and discuss the benefits they have derived from it? Additionally, what are the challenges associated with implementing token gated features, and how can they be overcome? I'm keen to understand this topic in depth, so a detailed response would be greatly appreciated.
