Why · Why now

600M people lack power. PayGo lacks trust

Around 600 million people in Sub-Saharan Africa lack reliable electricity. Pay-as-you-go solar is proven — but the industry is stuck on a structural problem: the money flow is opaque.

💸 Investors can't see the money

Funds disappear into an operating company's black box; revenue reports are trust-me numbers. Cross-border small-ticket investment can't verify, so it can't scale.

🏭 Operators get paid late

Splits are reconciled monthly by hand and settled through layers. The people doing the work get paid last; cash-flow pressure sits on the ground.

⚡ Users wait passively

Whether devices reach your village depends on the two loops above. The cost of distrust lands on the people who need power most.

🔗 Trustless

The split rule is hard-coded in the contract. Every payment is auto-sent 50/40/10 to the three parties, on-chain and auditable — the platform cannot skim.

🧩 Reuse a proven contract

Built on RWAInvest (crowdfunding + split + SRT shares + UUPS upgradeable). eCandle deploys its own instance; economics are isolated per batch.

Proof · Not a concept — real device, real money, real chain

A real device lights up, real txns on-chain

  1. ⚡Real device eCandle-003 is live on the platform — scan, pay, and the device really powers on (the scan-to-pay rail currently runs on testnet); real-money splits on mainnet are field-tested via direct wallet pay and cash collection, $0.10 each.
  2. ⛓eCandle's own ECandleRWA v2 contract is deployed on-chain — fully funded raise → finalize → real-money yield splits, all on-chain, every step with a tx hash.
  3. 🔍Anyone can verify right now — 7 frontends are live; the impact page streams from the production database and the contract.

USER PAYS → ON-CHAIN SPLIT

$0.10 of revenue, split three ways instantly

The user pays for electricity → keeper calls depositYield → the contract auto-pays by the hard-coded ratio (below: an actual $0.10 mainnet split, in USDC):

50%
Investor pool $0.05
40%
Operator $0.04
10%
Platform $0.01
✅ Two $0.10 real-money splits verified on mainnet · operator 40% + platform 10% land instantly · investor 50% pooled for claiming
* The scan-to-pay rail still runs on testnet; real-money mainnet splits were verified via the direct-wallet-pay and cash-collection rails.

Unit economics · One device, by the numbers

One device — what each party earns

Estimated from public PayGo-solar industry benchmarks in East/West Africa ($0.10–0.20 per household per day at Sun King, M-KOPA and peers). Industry-benchmark assumptions, not a promise of returns — to be calibrated with pilot data.

📟 Per-device revenue (assumed)

$3–6 / month per household → $36–72 / year per device. One-off device + deployment cost ≈ $60–100, covered by crowdfunding.

💰 Investors (50%)

Earn $18–36 / device / year — roughly 20%–45% gross annualized on device cost (before 3–5 yr device life, defaults and FX). Settled on-chain per payment, verifiable anytime.

🏭 Operator (40%) + platform (10%)

Operators earn $14–29 / device / year for distribution, maintenance and collections — deploy more, earn more. The platform's 10% is protocol revenue that scales linearly with the network.
