The official decentralized application for CeloHT education, a community agent network, and reforestation, built on the Celo ecosystem.
This is a decentralized application that lets people learn financial and Web3 basics, connect with verified community agents, and support reforestation projects — all through a wallet compatible with Valora, on the Celo ecosystem.
This is not an exchange, not a DeFi protocol, and not a token project.
No token is created or issued anywhere in this codebase. Every smart
contract, page, and workflow exists to support CeloHT's three permanent
pillars see docs/mission.md.
| Pillar | What the dApp does |
|---|---|
| Education | Courses, quizzes, progress tracking, and soulbound (non-transferable) on-chain certificates on completion |
| Agent Network | A directory and map of verified community agents, backed by an on-chain registry |
| Reforestation | Verified planting records and direct cUSD donations to registered projects |

See docs/architecture.md for the full breakdown.
- Frontend: Next.js, TypeScript, Tailwind CSS, hand-authored shadcn/ui-style
components (built on Radix primitives — see
docs/architecture.mdfor why these aren't installed via the shadcn CLI in this environment) - Web3: wagmi, viem, WalletConnect (for Valora and other mobile wallets)
- Contracts: Solidity 0.8.27, Hardhat, OpenZeppelin Contracts 5.x
- Off-chain data: Supabase (optional — the UI runs on documented sample
data without it; see
apps/web/src/lib/data/README.md) - CI/CD: GitHub Actions (build, lint, typecheck, contract tests, CodeQL, Dependabot)
git clone https://github.com/celo-ht/dapp.git

# Frontend
npm run dev # http://localhost:3000
# Contracts
npm run contracts:compile
npm run contracts:testSee docs/development.md for the full guide,
including required environment variables, and
docs/deployment.md for how contracts and the
frontend ship to production.
The contract suite (5 contracts, 30 passing tests) is complete and
audited internally, but not yet deployed to Celo mainnet or Alfajores
— see docs/deployment.md for exact status and
ROADMAP.md for the plan. Pages that read on-chain data
detect this and fall back to clearly labeled sample data rather than
showing broken or fabricated numbers.
The full index lives in docs/README.md, including
architecture, security, API, deployment, and contribution guides.
