Self-Hosted TRC20 Deposit Integration

I run a custom PHP + MySQL website and need a fully self-hosted USDT (TRC20) deposit flow.
Here is what the job entails:

• Each user must receive an automatically generated, unique TRC20 wallet address.
• A service written in the language of your choice should monitor those addresses—either through TronGrid or a locally synchronised Tron node—and detect confirmed USDT transfers in real time.
• Once a transfer is confirmed, an SQL call must update the user’s available balance in my existing database tables.
• The entire stack must remain under my control; please keep third-party payment gateways (CoinPayments, NowPayments, Plisio, etc.) out of the solution.
• Apply standard encryption protocols for key storage, address generation, and any communication between the monitoring service and the PHP backend.

When you reply, start with “TRON-EXPERT” so I know these requirements are clear. If you have questions about my current schema or server environment, feel free to ask—clean, well-documented code is the end goal.
