Piggycell is redefining how we think about everyday energy use by connecting South Korea’s physical shared charging network to a blockchain experience. With over 14,000 charging stations, 100,000+ portable batteries, and 4+ million users, it’s not just a token project - it’s a fully operational DePIN (Decentralized Physical Infrastructure Network) with real-world traction.
How It Works
Charge-to-Earn
When users rent and charge a battery via the Piggycell app, each session is logged on-chain. These usage events are converted into PIGGY token rewards.
Dominate-to-Earn
Piggycell issues region-based NFTs that represent ownership or claims on charging infrastructure. Holders receive rewards based on real, verifiable usage in their region, not just speculation.
Engagement Mechanics
Beyond charging, users can earn through daily check-ins, referrals, and challenges. All these actions are tracked on-chain, making the reward system transparent and auditable.
Under the Hood
- •The platform runs on opBNB, a high-throughput, low-cost Layer 2 on BNB Chain, which is ideal for handling the volume of real-world charging events.
- •Each session - from renting to returning a battery — is recorded as a smart contract event, ensuring trustless and automated reward distribution.
Backing & Growth
- •Piggycell raised $10M in a seed round, with backing from Animoca Brands, ICP Hubs, and others.
- •The project already dominates ~95% of South Korea’s shared power bank market.
- •It plans to further expand via its DePIN model, minting NFTs to represent regions, and scaling to new geographies.
Why It Matters
- •
Real-World Utility
Unlike many crypto projects that are purely speculative, Piggycell runs a service people actually use power banks.
- •
Transparent Reward System
Every charging session is tracked on-chain, linking token rewards directly to verified physical usage.
- •
Long-Term Alignment
With NFTs and staking, users and infrastructure owners are incentivized to stay invested in the network’s growth.
- •
Scalable Model
By turning physical devices into on-chain assets, Piggycell could serve as a blueprint for other infrastructure-based DePIN projects.
Piggycell isn’t just a token, it’s a working, real-world network that rewards people for a mundane but essential activity: charging their devices. As it scales, this model could redefine how physical infrastructure and blockchain converge.
