The on-chain rails for
real-world energy.

Build on verifiable energy + carbon data — a composable DePIN primitive. eCandle exposes an open REST API, on-chain contracts on Polygon, and verifiable device telemetry so you can ship energy dApps, carbon integrations and ReFi products without deploying physical infrastructure from scratch.

// the primitive

Real-world energy data
is a scarce primitive.

Verifiable energy + carbon data on-chain is valuable and hard to source. eCandle already runs the physical layer and the settlement rails — you compose on top.

01Why

Composable, verifiable data

Devs building carbon markets, energy dApps and ReFi want real-world energy + carbon data and payment/settlement rails — but standing up physical infrastructure and on-chain plumbing from scratch is expensive and slow.

02What

An API + on-chain contracts

eCandle exposes a REST API, on-chain contracts (RWAInvest on Polygon) and verifiable energy/impact data as building blocks — integrate payments, read device telemetry, build on on-chain energy and carbon data.

03How

Ship your product

Use the REST API (device status, payments, network stats), the on-chain contracts (invest / claim / 50-40-10 split) and webhooks → build energy dApps, carbon integrations, dashboards and ReFi products.

// building blocks

First-class rails to
build on.

Concrete, documented, composable. No black boxes.

🛰️

Open REST API

Public network stats, device status and telemetry, and payment endpoints. JSON in, JSON out — read the whole network without an SDK.

GET /v1/public/stats
📜

On-chain contracts

RWAInvest on Polygon: setup assets, invest, deposit and claim yield. Every split, invest and claim is a public, verifiable transaction.

RWAInvest.sol

Verifiable telemetry

Every kWh delivered, session and payment is anchored on-chain — not a self-reported PDF. Audit the proof, don't trust a claim.

Webhooks

Subscribe to payment, split and device events. React in real time — trigger settlement, mint receipts or update your dashboard.

event: payment.split
🧩

DePIN / ReFi composable

On-chain energy and carbon data becomes a Lego brick — pluggable into carbon markets, DePIN networks and regenerative finance.

Payment rails

USDC settlement with a hard-coded 50 / 40 / 10 split per batch. Take payments and let the contract distribute — no reconciliation.

The contract
is the API.

RWAInvest turns real pay-as-you-go solar revenue into a composable on-chain asset. Read it, verify it, or build directly against these functions.

setupAsset(uint256 batchId, uint256 shares, uint256 pricePerShare)
Register a batch of solar devices as an on-chain asset — define its shares and terms.
investAsset(uint256 batchId, uint256 amount)
Fund a batch and receive pro-rata shares of its future energy revenue.
depositYield(uint256 batchId, uint256 amount)
Push real electricity revenue into the batch pool — the 50/40/10 split is applied on-chain.
claimYield(uint256 batchId)
Claim accrued yield pro-rata to your shares. Backed by real revenue, not emissions.
