KPI-based token lockers aren't exactly new—UMA rolled out a toolkit for this ages ago. The idea? Lock tokens based on performance metrics instead of just time. Sounds smart on paper, but here's the catch: adoption never really took off. Why? Teams struggled to define meaningful KPIs that actually made sense for their ecosystem. You can build the infrastructure, but if users can't figure out what metrics matter or how to use them effectively, the whole thing just sits there collecting dust. Classic case of "cool tech, unclear use case."
