# PBX: ReFi Air Quality Token Platform

> PBX is a full-stack Web3 ReFi (regenerative finance) application that enables trading of regional air quality tokens. The app uses real-time AQI data via oracles and smart contracts to assign value. When a region's air is cleaner, the token gains value, creating a financial incentive for environmental preservation. Transaction fees fund real environmental impact.
