説明
Harsa is a decentralized agricultural supply chain and marketplace platform designed to bridge the gap between farmers and merchants. The platform addresses long-standing issues in the agricultural sector, such as lack of transparency in product origins and payment insecurity for small-scale producers.
Built on Arbitrum, Harsa leverages Layer-2 technology to provide a fast, low-cost, and scalable environment for on-chain transactions.
Key Features:
Transparent Supply Chain: Every step of the production process—from planting to harvest—is logged on-chain, providing an immutable audit trail for buyers to verify product quality and origin.
Secure Escrow Payments: To ensure fair transactions, payments are held in an escrow smart contract and only released to the farmer once the buyer confirms receipt of the goods.
Real-time Market Index: Integrates live agricultural commodity data to help users make informed decisions based on current market trends.
Web3 Integrated Dashboard: A user-friendly interface for farmers to manage products, monitor earnings, and track delivery status directly through their wallets.
ハッカソンの進行状況
During this hackathon, I have successfully built a functional MVP of the Harsa platform. This includes developing and deploying the core escrow smart contracts on the Arbitrum Sepolia network to ensure secure and automated transaction handling. I also implemented a full-stack web application using Next.js and Supabase, featuring a seamless authentication system that supports both traditional login and Web3 wallet integration. Key features such as the merchant dashboard, on-chain activity logging (Farm Logs), and real-time commodity price tracking via external APIs are fully operational, providing a complete infrastructure for transparent agricultural supply chain management.
