Sentre protocol being open means the protocol charge should encourage community projects, including projects developed by the foundation. At this moment, automation is really needed to realize the ability of plug-and-play, which allows a pool to effectively change the target of the charge. The problem solver here is SEN, the universal interface of Sentre’s ecosystem. SEN lets all charges be unified to a single interface. The community projects now only consume one socket, therefore, LPs are free from the complexity of multiple assets.
