✈️ EventGuard — Autonomous Flight Delay Refunds, Powered by Real-Time Data

"Travel protection that just works — automated, trustless, and fully on-chain."

---

🧩 What is EventGuard?

EventGuard is a decentralized application (dApp) built on the Flare Network that enables instant, on-chain refunds for flight delays and cancellations — no paperwork, no call centers, no waiting.

By integrating real-time flight data via trusted APIs and cross-chain payment capabilities, EventGuard allows travelers to buy protection, monitor flight status, and claim refunds automatically — all governed by tamper-proof smart contracts.

🌍 The Problem We Solve

Flight disruptions cost travelers time, money, and peace of mind. Traditional compensation processes are:

• 🐌 Slow — Lengthy, manual claims and long waiting periods
• 🎲 Inconsistent — Varies between airlines, routes, and legal systems
• ❌ Opaque — Little transparency, confusing terms, endless support calls

---

✅ Our Solution

EventGuard delivers frictionless, fully-automated flight protection:

• ✈️ Real-time flight monitoring via trusted APIs
• 🔗 Blockchain-based logic with smart contracts
• 💸 Instant payouts in stablecoins — no intermediaries
• 🌉 Cross-chain support — pay and claim across different blockchains

---

🔧 How It Works

1. 🎫 Purchase Protection
   Buy a Flight Protection Pass using stablecoins like USDC (on Sepolia or Flare) — stored securely on-chain, linked to your wallet.

2. 📡 Real-Time Flight Monitoring
   EventGuard’s backend tracks your flight through a Flight Status API via the Flare Data Connector (FDC).

3. ⚠️ Automated Disruption Detection
   If your flight is reported as 'Delayed' or 'Cancelled', a claim becomes available immediately.

4. 💰 On-Demand, Verified Payouts
   With a simple click, EventGuard revalidates the flight status on-chain and triggers a smart contract payout directly to your wallet — in stablecoins like USDT, instantly.

🌐 Cross-Chain Magic

EventGuard isn't limited to one blockchain:

• Multi-Chain Payments: Buy protection using USDC on Sepolia (Ethereum testnet) or FLR on Flare.
• Cross-Chain Claims: Smart contracts check proofs from multiple chains using the Flare Data Connector (FDC).
• Oracles & Bridges: Use decentralized oracles (FTSO) for price feeds and secure cross-chain data validation.

No matter where your tokens are — your protection works seamlessly.
