### What exactly are MEV Bots?
**MEV bots** are automated investing instruments made To maximise income by exploiting a variety of inefficiencies in blockchain transactions.

### MEV Approaches
**MEV tactics** is usually categorized based on their approach to extracting worth through the blockchain. Below are a few popular techniques used by MEV bots:
