Chai Platform

Project Overview

Name: Chai Platform - Sustainable Coffee Production Financing

Tagline: Democratizing coffee production through blockchain-powered fractional ownership and transparent revenue sharing

Category: DeFi / AgriTech / Impact Investing

Problem Statement

Small-scale coffee farmers in East Africa face critical challenges:

• No access to capital - Traditional banks won't lend without collateral

• Unfair pricing - Farmers receive only 10-20% of retail coffee prices

• Limited market access - Cannot reach international investors

• High lending costs - Interest rates of 20-40% from informal lenders

• Zero transparency - Investors can't verify impact or fund usage

Solution

Chai Platform uses Mantle blockchain to create a transparent, efficient marketplace connecting coffee farmers with global investors through:

• Grove Tokenization - Coffee trees become tradeable NFTs

• DeFi Lending - Instant USDC loans using groves as collateral

• Automated Revenue Distribution - Smart contracts ensure fair profit sharing

• Real-time Monitoring - Satellite imagery and IoT sensors track grove health

• Fractional Ownership - Investors can own portions of groves starting at $10

Technical Architecture

Blockchain Layer (Mantle)

• Smart Contracts: Solidity contracts for grove tokenization, lending pools, and revenue distribution

• Token Standards: ERC-20 and ERC-721 for fungible tokens and NFTs

• Network: Mantle Sepolia Testnet

• Wallet Integration: MetaMask, WalletConnect

Backend

• Runtime: Node.js with TypeScript

• Framework: Express.js for API endpoints

• Database: SQLite with Drizzle ORM

• Build Tool: tsup for ESM compilation

Frontend

• Framework: Vanilla JavaScript (ES6 modules)

• Build Tool: Vite 6.4.0

• Styling: Custom CSS with glassmorphism design

Key Technologies

• ethers.js - Mantle blockchain and smart contract interaction

• better-sqlite3 - Local database

• drizzle-orm - Type-safe database queries
