The energy-backed money protocol

Stored energy stops being worth anything the moment the neighbourhood can't absorb it. Exergy is the settlement layer that lets that value travel instead — energy stored in one place can settle a bill on the other side of the world. The electrons never move. Only the value does.

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

A note is minted

A smart contract mints a note — ticker $XRGY — to the participant, proportional to the verified energy. No humans, no middlemen, and nothing sold to anyone: a note exists only because energy was stored.

The mechanism

What actually backs a note

Measured, not promised — and verifiable by anyone in a block.

A note is minted, never sold

No pre-mine, no token sale, no investor allocation. A note exists only when the protocol verifies that real energy has been stored — co-signed independently by the device and by the VPP operator, with a hard cycle ceiling the contract refuses to exceed. Minting always costs genuine hardware wear, which is what makes faking it pointless.

Backing is a live measurement

floating index = total verified energy in storage ÷ total notes

Recomputed continuously, on-chain, from those same measurements. Every holder can read the kilowatt-hours behind their note at any moment — alongside its market price. Nothing is self-reported and nothing is taken on trust.

The backing deepens by protocol

Every 1,000,000 notes minted, the mint rate halves. The same stored energy then yields fewer new notes — so the kilowatt-hours behind each existing note rise. A widening physical ratio, not a forecast. We state what the energy content is. We never promise what the price will be.

Nobody underwrites the liquidity

A note is born inside an energy network and is useful there the instant it exists — settling with a participant who needs it more than they need their grid supply. There is no bootstrap period and nothing for an institution to underwrite. Capital, if it comes, comes second.
