Automated USDT Payment Gateway Integration

Project Title:** Need PHP Developer for Automated USDT (TRC20) Payment Gateway Integration **Project Description:** I am looking for an experienced PHP developer to integrate a custom, fully automated USDT (TRC20) payment gateway into my existing PHP script. The system needs to be secure, automated, and designed with privacy in mind. **Key Requirements:** * **Unique User Addresses:** The system must dynamically generate a separate, unique USDT (TRC20) deposit address for each individual user on the platform. * **Automated Payment Detection:** The script should automatically monitor the Tron blockchain (e.g., using TronGrid API or a similar method) to verify incoming transactions. Once a deposit is confirmed, it should automatically credit the respective user's account balance in the MySQL database. * **Hidden Main Wallet (Auto-Forwarding):** For security and privacy, my central/main wallet must remain completely hidden from the users and the front-end. The system needs an auto-sweep mechanism that automatically forwards the funds from the user's unique deposit address to my hidden main wallet. * **TRX Fee Management:** The solution must include a mechanism to handle or fund the TRX (energy/bandwidth) required to transfer the USDT from the user's temporary address to the main wallet. * **Security & Encryption:** High security is mandatory. Private keys for the generated addresses must be securely encrypted and managed off-limits from public web directories. **Technical Stack:** * Custom PHP * MySQL **Ideal Candidate:** * Proven experience with TronWeb, Tron API, and handling TRC20 token transactions. * Previous experience building or integrating custom, non-custodial crypto payment gateways (avoiding high third-party fees is a plus). * Strong understanding of blockchain event listening and secure key management. If you have built similar automated crypto payment systems before, please include details or examples in your proposal. Budget 5000
