Final Day21!

Today i wanted to explore something related to attacks. so, it took me a while but I managed to write a piece of code that: 

- fetches transactions from each new block every 5 seconds.
- Stores transaction history in a shared memory structure (HashMap).
- Analyzes transactions for MEV patterns:
      1. Sandwich attacks (detects if a bot front-runs and back-runs a victim's trade).
      2. Front-running (detects if a bot submits a transaction with a higher gas price to execute first).
- Prints alerts when MEV activity is detected.

I wanted to use websocket for it, but I faced too many errors. so i decided to go with RPC. 

I'll probably continue with parsing this raw data into structured JSON tomorrow. Just for myself
Thank you Base Seoul for this opportunity!
