Own a piece of the energy transition, from one dollar.
Heliobond is a transparent green-bond investment pool on Stellar. Investors deposit USDC into a vault, receive shares in a pool of vetted renewable-energy projects, and an on-chain oracle scores each project for credit quality and green impact. Everything settles on-chain; anyone can verify it.

| Repo | What it is |
|---|---|
| contracts | Soroban smart contracts (Rust) — the investment vault and project registry. The on-chain source of truth. |
| backend | Stellar indexer + REST API + the oracle that scores projects from IoT and satellite data. |
| frontend | The investor app — Next.js, React, TypeScript. What you see at the demo. |
The three form a pipeline: contracts define the protocol, the backend indexes and enriches it, the frontend consumes both. Each repo builds and tests on its own.
We post scoped issues with acceptance criteria and file pointers so you can start without reverse-engineering the codebase. Look for the good first issue label in any repo, and read each repo's CONTRIBUTING.md first.
- New to the project? Start with a good-first-issue on the frontend.
- Rust? The contracts need deploy tooling and tests.
- TypeScript and APIs? The backend indexer and endpoints are wide open.
