Renewable energy cooperatives generate clean energy every day — but they can't prove it.
- No standardized way to record generation
- No verifiable certificate that travels with the energy claim
- No access to ESG markets, carbon offsetting programs, or institutional buyers
- Manual, paper-based processes that nobody trusts
Meanwhile, companies and funds with ESG commitments are actively looking for verifiable renewable energy claims — and can't find them.
The gap between cooperatives and buyers is a trust gap. BeEnergy closes it.
BeEnergy is a cooperative management dashboard + on-chain certification infrastructure on Stellar.
Every kWh registered by a cooperative becomes a proto-certificate: a verifiable, on-chain claim tied to a real meter, a real cooperative, and a real time period.
Smart meter sends reading → POST /api/meters/readings
↓
BeEnergy validates & mints token on Stellar (1 token = 1 kWh)
↓
Certificate is assigned to cooperative members
↓
External buyer (company / ESG fund) purchases certificate
↓
Buyer retires certificate on-chain (verifiable burn)
↓
Permanent, auditable proof on Stellar blockchain
No intermediaries. No PDFs. No trust required — the chain is the proof.
1. Register cooperative on BeEnergy
2. Add smart meters (physical IoT devices)
3. Meters send generation readings automatically via API
4. BeEnergy mints proto-certificates on Stellar
5. Manage members, view generation stats, track certificates
1. Browse available certificates by cooperative / technology / period
2. Purchase certificates (linked to specific on-chain tokens)
3. Retire certificate → recorded permanently on Stellar
4. Receive auditable proof of renewable energy support
BeEnergy supports two access methods — no setup required to try:
Email + Password (for admins, buyers, internal team)
/login → Supabase auth → JWT issued → Stellar wallet auto-assigned → /dashboard
Try it:
demo@beenergy.coop/Demo2026!
Stellar Wallet (for cooperatives with Freighter / xBull / Lobstr)
Connect wallet → Server issues challenge → User signs with private key
→ Signature verified on-chain → JWT issued → /dashboard
Both methods issue the same JWT and give full platform access. Wallet users can additionally sign on-chain transactions.
This is not a wrapper. Stellar is load-bearing infrastructure:
| What | How |
|---|---|
| Certificate issuance | Mint SEP-41 tokens directly on Stellar Testnet |
| Certificate retirement | On-chain burn, permanently auditable |
| Member allocation | energy_distribution contract splits tokens by participation % |
| Governance | community_governance contract for cooperative proposals |
| Wallet auth | Challenge-response signature verification (no gas, no tx) |
| Token standard | SEP-41 (fungible) with OpenZeppelin Stellar Pausable + Upgradeable |
| Contract | Address | Purpose |
|---|---|---|
energy_token |
CCYOVOFD...MRPBA6 |
SEP-41 token — 1 token = 1 kWh certified |
energy_distribution |
CBTDPLFN...NX2UDZ |
Distributes certificates to members |
community_governance |
CCH2EXXN...BJD6YI |
Cooperative on-chain governance |
Built with OpenZeppelin Stellar Contracts v0.5.1 + Soroban SDK 23.1.0 — 65 tests passing.
We validated the problem directly with:
- Energy cooperatives in Argentina — confirmed the pain of not being able to sell renewable attributes
- ESG compliance teams — confirmed demand for verifiable, auditable certificates
- Climate program coordinators — confirmed interest in blockchain-based proof over PDFs
Key insight: the bottleneck isn't production — cooperatives generate plenty. The bottleneck is verifiable proof. BeEnergy solves exactly that.

cargo test| Level | What | Status |
|---|---|---|
| 1 — Internal registry | Token = verifiable production record | ✅ Live on Testnet |
| 2 — Verified certification | IoT oracles + independent meter validation | 🔄 Next |
| 3 — Recognized standard | Integration with I-REC, Energy Web, TIGR | 🔮 Future |
BeEnergy is designed to plug into Stellar's growing DeFi and payments ecosystem. Planned integrations from the SCF Integration Track:
| Integration | What it unlocks for BeEnergy |
|---|---|
| DeFindex | Cooperatives earn yield on certificate proceeds held in vaults — idle capital works while certificates wait for buyers |
| Blend Protocol | Use certificates as collateral for credit lines — cooperatives access working capital without selling |
| Soroswap | AMM liquidity pool for certificate tokens — enables price discovery and secondary market for renewable attributes |
| USDC (Circle) | Stablecoin payments for certificate purchases — buyers pay in USDC, cooperatives receive USDC, no FX volatility |
| Aquarius | Liquidity incentives for BETOKEN/USDC pairs — bootstraps the certificate secondary market |
| Fiat On/Off Ramp (SEP-24) | Cooperatives receive payments in local fiat (ARS, COP, BRL) via Stellar anchors — no crypto knowledge required |
| Stellar Turrets / smart oracles | Automated certificate minting triggered by verified IoT meter readings — removes manual intervention |
These integrations are load-bearing features on the product roadmap, not checkbox items. DeFindex is the most immediate — partial integration already exists in the codebase.
