Overcoming Fragmentation in EV Charging Networks

EV charging networks are notoriously fragmented, with each station operating on its own system and set of transaction protocols. This fragmentation forced EV owners to juggle multiple apps and payment modes, leading to a disjointed and frustrating user experience. Additionally, the lack of interoperability across different blockchain networks posed significant challenges, underlining the need for a unified, secure, and user-friendly solution.
