I need an anonymous USDT (TRC20) payment gateway wired into my custom-built PHP site, which powers a crypto-trading service. The flow must accept only TRC20-based Tether, collect no KYC or personal data, and confirm transactions automatically so a trade can proceed the moment funds arrive. Your task covers everything from wallet generation and secure callback handling to a clean drop-in module that plays nicely with my current codebase. I will share architecture details and endpoint specs once we start, but you can assume standard PHP MVC patterns and a MySQL back end. What I expect from you • A fully working, production-ready USDT-TRC20 gateway with automatic payment detection and status callbacks • Clear, concise setup/maintenance documentation (endpoints, environment variables, cron/webhook instructions) • Robust error handling, tamper-proof signature or hash verification, and rate-limited APIs to keep the gateway secure and reliable When you reply, please point me to live or repository examples of similar crypto payment work—especially anything on the Tron network—and outline your estimated timeline plus cost. If you have a preferred third-party processor or plan to build the interaction directly on Tron-Grid or similar nodes, let me know; the main requirement is that user anonymity stays intact. I’m ready to get this integrated quickly, so the clearer your past experience and implementation plan, the faster we can move forward. My budget is very low
