Project Overview

AgroPredict is a Decentralized Agricultural Futures Platform specialized for Ecuadorian farmers and the broader Latin American agricultural market. Its primary mission is to eliminate exploitative intermediaries by enabling farmers to tokenize their future crops and sell directly to buyers through blockchain technology.

The platform provides AI-powered price predictions, smart contract escrow, transparent marketplace, and direct farmer-to-buyer transactions while ensuring fair pricing and secure payments for agricultural products.

A key feature of AgroPredict is its dual-layer architecture combining on-chain smart contracts for secure transactions with off-chain AI models for price prediction and market analysis, while maintaining blockchain transparency for all critical operations.

🎯 Why AgroPredict Must Scale

1. Agricultural Income Crisis 🌾

Small farmers receive only 10-15% of final product value due to intermediary exploitation. AgroPredict increases farmer income by 40-60% through direct sales.

2. Financial Inclusion Gap 💰

70% of small farmers lack access to formal financial services. Blockchain enables direct access to global markets and capital.

3. Information Asymmetry 📊

Farmers often sell at below-market prices due to lack of price information. AI predictions provide market intelligence previously available only to large agribusinesses.

4. Food Security Impact 🍽️

Improved farmer incomes increase agricultural investment, productivity, and food security for growing populations.

5. Climate Adaptation 🌡️

Smart contracts enable new forms of climate insurance and adaptation financing for vulnerable farming communities.

6. Economic Development 🏗️

Agricultural digitization drives broader rural economic development and poverty reduction.
