🔍 Key Features

🧠 AI Health Analysis

• Real-time RPC health monitoring via "getHealth"
• Risk scoring and anomaly detection (ML-ready)
• Adaptive classification: SAFE / MEDIUM / HIGH

🔁 Intelligent Response Engine

• Automatic RPC failover (multi-endpoint rotation)
• Dynamic request throttling
• Smart contract trigger for critical risk scenarios

🤖 Alert System

• Telegram alerts for HIGH-risk conditions
• Real-time notification for network anomalies

📊 Observability Layer

• "/metrics" endpoint for monitoring tools
• Grafana-ready integration for dashboards
• Structured output for analytics pipelines
