Decentralized agricultural supply chain on Stellar — harvest tokenization, escrow payments, on-chain credit scoring, and pre-harvest financing for African smallholder farmers. # 🌾 AgroChain Africa — Decentralized Agricultural Supply Chain on Stellar > Empowering smallholder farmers across Africa with transparent payments, on-chain credit history, pre-harvest financing, and immutable trade records — built on the Stellar blockchain. --- ## Table of Contents - Overview - Problem Statement - Solution Architecture - Tech Stack - Project Structure - Core Features - Stellar & Soroban Integration - Smart Contracts (Soroban) - Backend — NestJS - Frontend — Angular - Off-chain Integrations - Data Models - API Reference - Environment Variables - Getting Started - Testing - Deployment - Roadmap - Contributing - License --- ## Overview **AgroChain Africa** is a full-stack decentralized application (dApp) that digitizes and trustlessly automates the agricultural supply chain — from planting season through post-harvest settlement. It connects smallholder farmers, aggregator cooperatives, commodity buyers, and financial lenders on a shared, tamper-proof ledger powered by the Stellar network and Soroban smart contracts. The platform solves three compounding failures that lock African farmers in poverty cycles: 1. **Payment opacity** — farmers are paid weeks or months after delivery, at prices they didn't agree to 2. **Credit invisibility** — no formal credit history means no access to pre-harvest financing 3. **Post-harvest losses** — caused by inability to access storage financing or sell forward contracts AgroChain Africa puts farmers in control: they tokenize their harvests, lock in buyer commitments via escrow, build on-chain credit profiles, and receive instant cross-border settlements — all from a feature phone via USSD or a smartphone app. --- ## Problem Statement | Problem | Scale | AgroChain Response | |---|---|---| | 30–40% post-harvest losses | Sub-Saharan Africa | Pre-harvest forward contracts + escrow | | 600M+ unbanked rural adults | Africa-wide | Stellar wallet + mobile money anchor | | No formal credit for smallholders | 70% o …
