## Overview
|
|
|
|
The MEV Bot is a sophisticated Maximal Extractable Value (MEV) detection and exploitation system written in Go. It monitors the Arbitrum sequencer for potential swap opportunities and identifies profitable arbitrage opportunities using advanced mathematical calculations and concurrent processing.
