# MEV Bot Comprehensive Audit System

## Overview

The MEV Bot project now includes a comprehensive audit system designed to validate every aspect of the system from mathematical precision to security, performance, and compliance. This document provides a complete guide to the audit infrastructure and how to use it effectively.

## Architecture

The audit system consists of 8 specialized tools that can be run independently or orchestrated together:
