I built a full-stack DeFi liquidation indexer from scratch — tracking real-time liquidation events across Aave V3, Compound V3, Morpho, and Spark on 8 EVM networks. In this demo, I walk through the complete system end-to-end: 🔍 What it does: - Scans 8 EVM networks every 30 seconds for liquidation events - Normalizes different protocol event formats into a unified data shape - Persists everything to PostgreSQL - Serves a REST API via Hono - Displays a live dashboard built with Next.js - Sends instant Telegram alerts to subscribers 📡 Subscribe to live alerts: https://t.me/KayKayDLI_bot Send /start to receive notifications the moment a liquidation is detected ⚙️ Tech stack: viem · Node.js · PostgreSQL · Hono · Next.js · Tailwind CSS · Telegram Bot API 🌐 Networks: Ethereum · Arbitrum · Base · Optimism · Polygon · Avalanche · Linea · zkSync 📦 Protocols: Aave V3 · Compound V3 · Morpho Blue · SparkLend Github: https://github.com/Kelechikizito/defi-liquidation-indexer ⏱️ Timestamps: 0:00 — Landing page 0:30 — Live dashboard overview 1:15 — Chain filtering & block tracking 2:00 — Liquidation feed & explorer links 2:45 — Terminal scanner logs 3:10 — Telegram alert demo #DeFi #Ethereum #Blockchain #Web3 #Liquidation #Aave #Compound #Morpho #NodeJS #NextJS
