OpenVPP is an on-chain payment layer built for the energy utility sector. It combines a stablecoin settlement layer with a decentralized integration layer for distributed energy resources (DERs), enabling real-time, machine-scale transactions without centralized gateways. This forms an open-source virtual power plant.

Its payment engine uses energy-aware smart contracts with dollar-pegged stablecoins, allowing a single token to represent currency, kilowatt-hours, or avoided CO₂. A universal DER protocol enables devices like meters and EV chargers to discover each other, authenticate, and exchange value peer-to-peer.
