Introduction

Autonomous DeFi vault that auto-withdraws your funds when systemic risk is detected via Chainlink CRE.

What is GuardAI?

GuardAI is an autonomous DeFi risk protection system. It monitors systemic risk across major DeFi protocols in real time and automatically withdraws user funds before a crisis hits — with zero manual intervention.

No alerts. No waiting. No human trigger required.

---

The Problem

DeFi users are exposed to systemic risk events:

• 📉 ETH price crashes

• 🔓 Lido, Aave, or MakerDAO TVL drains

• 💥 Protocol exploits and contagion events

By the time users react manually, it's too late. GuardAI eliminates that reaction-time gap.

How It Works

Chainlink CRE Workflow (every 60s)
        │
        ├─ Chainlink Data Feed → ETH/USD price
        ├─ DeFiLlama HTTP API  → Lido / Aave / MakerDAO TVL
        │
        └─ Compute Systemic Risk Index (weighted score 0–100)
                │
                └─ Write score on-chain → VaultSentinel.setRiskScore()
                        │
                        ├─ Score < 70  → Vault stays ACTIVE ✅
                        └─ Score ≥ 70  → EMERGENCY triggered 🚨
                                │
                                └─ All user ETH + ERC20 returned instantly
