Autonomous Risk Monitoring

The brain of GuardAI — a Chainlink CRE workflow that runs every 60 seconds, aggregating multi-protocol signals into a single Systemic Risk Index.

How It Works

Every minute, the CRE workflow:

1. Fetches ETH/USD price from Chainlink Data Feed

2. Fetches Lido, Aave, MakerDAO TVL from DeFiLlama

3. Computes a weighted Systemic Risk Index (0–100)

4. Writes the score on-chain via setRiskScore()

If the score hits 70 or above, the vault automatically enters EMERGENCY.

Risk Signals

Signal	Source	Weight
ETH/USD Price Drop	Chainlink Data Feed (0x5f4eC3...)	30%
Lido TVL Drain	DeFiLlama API	25%
Aave TVL Drain	DeFiLlama API	25%
MakerDAO TVL Drain	DeFiLlama API	20%

Score Formula

$\text{RiskScore} = (\text{priceScore} \times 0.30) + (\text{lidoScore} \times 0.25) + (\text{aaveScore} \times 0.25) + (\text{makerScore} \times 0.20)$

Each factor score is computed as:

Factor	Baseline	Formula
ETH Price	$3,500	min(100, priceDrop% × 2.5)
Lido TVL	$10B	min(100, drain% × 2)
Aave TVL	$8B	min(100, drain% × 2)
MakerDAO TVL	$6B	min(100, drain% × 2)

Score is always an integer 0–100.

Live Dashboard

The Risk Gauge on the Home tab reads lastRiskScore directly from the contract every 5 seconds via useReadContract. No backend. No intermediary.

Score Range	Color	Vault State
0 – 39	🟢 Green	ACTIVE — Safe
40 – 69	🟡 Yellow	ACTIVE — Elevated
70 – 100	🔴 Red	EMERGENCY triggered

Chainlink Integration

- id: fetch_eth_price
  type: chainlink-data-feed
  params:
    feedAddress: "0x5f4eC3Df9cbd43714FE2740f5E3616155c5b8419"  # ETH/USD Mainnet
  output: eth_price

The chainlink-data-feed step type is native to Chainlink CRE — it fetches verifiable price data directly from the on-chain aggregator, no third-party API needed.
