AgriGuard is a decentralized weather-based parametric insurance platform built on blockchain technology. It provides automated crop insurance for farmers, protecting them against extreme weather conditions such as droughts and heat stress. The platform uses Chainlink Oracles to fetch real-time weather data and automatically processes claims when predefined weather thresholds are exceeded.
Unlike traditional insurance, AgriGuard operates on a parametric model where payouts are triggered automatically based on objective weather data from Open-Meteo API, eliminating lengthy claim processes and reducing fraud.
AgriGuard provides three scientifically-backed insurance categories based on agricultural research:
Protects farmers during the critical planting season when insufficient moisture can prevent seed germination and establishment.
Covers the vegetative and reproductive growth stages when water stress significantly impacts crop yield and quality.
Safeguards against extreme temperatures that cause crop damage, reduced photosynthesis, and yield loss.

The AutomatedWeatherPolicy smart contract manages all insurance policies, integrates with Chainlink Functions for weather data, and processes automated claims. All transactions are publicly verifiable on the Ethereum Sepolia testnet.
Chainlink Functions: Fetches weather data from Open-Meteo API using decentralized oracle network.
Chainlink Automation: Monitors policies daily and triggers automated claim processing when weather thresholds are exceeded.
Landing page introducing the platform, explaining parametric insurance, and showcasing the three insurance categories with their scientific thresholds.
Interactive form for purchasing insurance policies. Users select policy type, coverage duration (30-365 days), farm location coordinates, and see real-time premium calculations before confirming the transaction.
Personal dashboard displaying user's policies, coverage statistics, and claim history. Shows active, expired, and claimed policies with detailed information cards.
Detailed view of a specific policy including insurance type, coverage amount, location coordinates, validity period, weather thresholds, and links to blockchain transactions.
Real-time claim monitoring interface displaying all automated claims, payout amounts, timestamps, and direct links to blockchain transactions for verification.
