Automated USDT Payment Gateway Integration
Summary
Freelancer Client is hiring: Automated USDT Payment Gateway Integration.
Location: Remote
Project Title:** Need PHP Developer for Automated USDT (TRC20) Payment Gateway Integration
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
Skills: PHP, JavaScript, Software Architecture, MySQL, Blockchain, Payment Gateway Integration, API Development, Cryptocurrency
Budget: $1500–$12500 USD

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.
