Introduction

The project showcases how to use the Web3 library to interact with an Ethereum smart contract. It includes sample code to connect to a local Ethereum blockchain, subscribe to pending transactions, fetch the creator's address of a smart contract, and listen to the 'Transfer' event and buy the desired Token before the targeted wallet
