Contract farming offers a viable solution for stabilizing farmer incomes by securing market access through forward contracts. However, traditional models face challenges such as fluctuating market prices, delayed payments, poor communication, and risk uncertainties that can lead to overproduction. This paper presents AgriShield, a comprehensive digital platform that bridges the gap between farmers and buyers by facilitating assured contract farming agreements. AgriShield provides functionalities including detailed crop demand listings, minimum base pricing, dynamic negotiation tools, AI-powered price predictions, real-time multi-channel communication, secure Aadhaar-based KYC and payment processing, quality checks, and crop insurance. Notably, the platform also reduces overproduction by notifying farmers of actual market demand, thereby aligning production with buyer requirements. A pilot implementation demonstrates reductions in income volatility, enhanced operational efficiency, and improved transparency and trust among stakeholders
