Architecture

How Exergy works

Three simple steps. Fully autonomous.

01

Battery charges

Home or grid battery charges from solar, wind, or grid. A standard IoT BMS (Tesla, BYD, Sonnen) reports kWh to the protocol — no custom hardware.

02

Network verifies

Every reading is cryptographically co-signed at the device and VPP level before it counts — live today. A Chainlink oracle layer (3-of-5 consensus + DSO grid cross-check) hardens it further in Phase 1.

03

Token mints

A smart contract on Arbitrum mints $XRGY proportional to verified energy. No humans. No middlemen. Floating index, halving built in.
