Non-Playable Characters (NPCs) refer to automated entities in gaming that players cannot control. In the context of online platforms and decentralized finance, NPCs can symbolize automated bots or algorithms that perform specific tasks without human intervention.These bots may execute trades, manage portfolios, or provide customer support. Unlike human participants, NPCs operate based on predetermined rules and algorithms, ensuring efficiency and speed in various operations.While NPCs can enhance user experience by streamlining processes, they also pose challenges. Their predictable behavior can be exploited, leading to potential security risks or market manipulation.Overall, NPCs play a significant role in enhancing automation and efficiency, but they must be designed with care to mitigate associated risks.
