Description of the "Starting Download After Crypto Payment" Script

Overview

The "Starting Download After Crypto Payment" script facilitates the automatic download of a file following a successful cryptocurrency transaction. It is designed to work seamlessly with the Ethereum blockchain and utilizes MetaMask for transaction handling. This script is particularly useful for selling digital products securely, ensuring that the download only starts once the payment is confirmed.
