Abstract—This project presents a decentralized blockchain-based application designed to improve transparency, traceability, and fairness within the agricultural supply chain. Instead of relying on traditional centralized systems that are vulnerable to data manipulation, delays, and pricing conflicts, the proposed system records every transaction on an immutable distributed ledger, ensuring secure and tamper-proof data flow among farmers, distributors, retailers, and consumers. Through a user-friendly web interface, stakeholders can register their role, manage product information, and track produce from its point of origin to its final destination. Smart contracts automatically verify transactions, enforce agreements, and facilitate real-time updates without requiring manual oversight. When products move through different stages, their corresponding data is captured and converted into structured blockchain entries that ensure complete lifecycle visibility. The entire application operates through a secure login portal, integrates MetaMask for authentication, and offers multiple modes for viewing product history, financial transactions, and quality records. The goal of this system is to promote a reliable, transparent, and corruption-free supply chain environment using simple, accessible tools that can be adopted by agricultural communities. This decentralized approach is especially beneficial for farmers, cooperatives, and stakeholders in regions where unfair pricing, information gaps, or lack of verification mechanisms commonly hinder market efficiency.
