is a Solana-based agricultural marketplace that gives South African smallholder farmers access to a single bundled service — certified seeds, fertilizer, and parametric crop insurance — delivered on credit and repaid at harvest.
# Mazra'at albaan
**A Solana-based agricultural marketplace for South African smallholder farmers.**
*Internal codename: **Vuna** (the Solana program crate, the technical shorthand).*
Mazra'at albaan gives small farmers seeds, fertilizer, and drought insurance on credit — bundled into one *Grow Pack* and repaid at harvest. When bad weather hits, the parametric policy pays out automatically. The farmer never sees a wallet, a stablecoin, or the word "blockchain".
Built for the **Solana 2026 Frontier Hackathon — Physical World Applications track**. Final placement: **#1 in South Africa · #3 in Africa · #8 globally.**

The demo pack is in `InsurancePaid` status with **R 1 400** paid out at 40% rainfall (tier 3). Every number on the dashboard, the marketplace, and the insurance view comes from a real on-chain read — no mock data anywhere.
## Two surfaces, one codebase
| Route | Audience | Auth + Wallet |
|-|-|-|
| `/dashboard` | Farmer (mobile-first) | Supabase email login → Privy email-OTP custodial wallet (no seed phrase, no chain words) |
| `/coop` | Cooperative officer / insurance admin | Phantom / Solflare via wallet-adapter — they sign approvals, disbursements, and drought-payout triggers |
The two-tier auth is deliberate: farmers should never see a private key; the co-op staff should, because they're operating the program. Same code, different doors.
