Piggycell is a DePIN and RWA project that transforms a nationwide power bank sharing network into a Web3 ecosystem. By linking real-world charging activities to on-chain data, Piggycell creates a transparent and reward-driven infrastructure. Users can earn daily incentives through Charge-to-Earn, NFT ownership, and gamified missions, bridging the gap between physical infrastructure and blockchain. The platform aims to make Web3 adoption seamless for everyday users by turning real utility into digital value. Piggycell represents a new model of decentralized infrastructure, combining real-world business with tokenized incentives.
