That's what the Finish-Up-A-Thon is all about.

This is a submission for the GitHub Finish-Up-A-Thon Challenge

What I Built PayFusion AI is a full-stack intelligent payment aggregation system that supports multi-channel payment with one QR code using platforms like Alipay, WeChat, USDT, and PayPal. It integrates automatic transfers, fund distribution, QR code parsing, and AI-driven real-time payment monitoring. This project started out as a simple Flask QR code generator but gradually evolved into a complete payment automation platform. Key features include: Multi-channel payment with one QR code: Dynamically generates aggregated QR codes and intelligently routes users to the corresponding payment channels based on their scanning environment. AI fund monitoring Agent: Monitors payment status in real-time, automatically confirms fund arrival, and triggers subsequent workflows. Dual-platform architecture: Flask Web management backend + Telegram Bot mobile control. Automatic transfer engine: Supports automatic collection and fund distribution of USDT on the TRON network. Offline signature and blind signature: Complete blockchain security testing module. The entire project was developed and deployed entirely in a Termux Android terminal, eventually pushed to GitHub and automated using Railway/Render.
