Introduction

The MEV Tracker Page is a planned feature for the InfraWatch platform that will provide real-time monitoring of Maximal Extractable Value (MEV) activities on the Solana network. Currently, the page serves as a placeholder with coming-soon functionality, displaying preview statistics and feature descriptions while the actual MEV tracking capabilities are under development.

MEV represents the maximum value that can be extracted from legitimate transaction permutations in a blockchain network. On Solana, this primarily involves monitoring Jito bundles, arbitrage opportunities, and transaction ordering advantages that validators and searchers can exploit.

Core Components

Frontend Components

The MEV Tracker page consists of several key frontend components that work together to present the upcoming functionality:

Main Component Structure

The primary component follows a card-based layout with three main sections:

• Header Section: Displays the page title and description
• Coming Soon Card: Features animated elements and feature highlights
• Preview Statistics Grid: Shows mock MEV metrics
• Information Banner: Provides educational content about MEV tracking

Custom Icon System

The component utilizes a custom SVG icon library that replaces external dependencies like Lucide React. The icons include:

• Zap (lightning bolt) for speed and activity
• TrendingUp (chart) for growth metrics
• Target (bullseye) for success rates
• Coins (currency) for monetary values

Component Composition Pattern

The page demonstrates a reusable component pattern with:

• ComingSoonCard: Animated cards with hover effects
• StatCard: Consistent metric display with color-coded variants
• Flexible layout using CSS Grid for responsive design

Backend Infrastructure

The backend provides the foundation for real-time MEV data collection and distribution:

WebSocket Architecture

The system uses Socket.IO for real-time bidirectional communication between the server and clients. The WebSocket setup handles:

• Client connection management
• Event broadcasting
• Connection counting and monitoring
• Graceful error handling

Data Collection Pipeline

The critical poller job orchestrates data collection every 30 seconds:

• Network snapshot collection from Solana RPC
• Priority fee analysis via Helius
• RPC provider health monitoring
• Database persistence and caching

• index.js:13-52
• criticalPoller.js:21-100

Architecture Overview

The MEV Tracker functionality is designed to integrate seamlessly with the existing InfraWatch architecture through a real-time data pipeline:
