Project Title: Enhance Laravel Script for Step-by-Step USDT Payment Integration

I have a PHP script using the Laravel framework for a finance and investment-themed website. I need an enhancement to the dashboard to add a USDT payment section. The goal is to enable users to choose an investment package and make staged payments to my USDT wallet. The process should be step-by-step, ensuring full security. After each payment, users must provide the payment link to the site, and the site should update their account balance accordingly. The implementation should include measures to prevent fraud and theft.
