Setting Up Epusdt with Unicorn Digital Card for USDT Payments (aaPanel)

Introduction

Integrate epusdt with Unicorn Digital Card to enable USDT payments.

Project Highlights

Privately deployable USDT payment middleware (TRC20 network)
Written in Go, supporting x86/ARM architectures
Multi-wallet address rotation for higher transaction concurrency
Asynchronous queue processing for high performance
Telegram bot integration for real-time notifications

Prerequisites

Running MySQL, Redis, and Supervisord services
Telegram bot token (@BotFather)
Unicorn Digital Card setup (e.g., fk.skygv.com)
Dedicated payment domain (e.g., upay.skygv.com)

Step-by-Step Guide

1. Create a New Website in aaPanel

Add a static website (no PHP/FTP required) with a database.
Bind the payment domain (e.g., upay.skygv.com).
Enable HTTPS redirect if using SSL.

2. Import SQL Database

Option 1: Manual Import

Download the latest SQL file from epusdt GitHub.
Upload and extract the epusdt release package to the website directory.

Rename .env.example to .env and configure:

app_uri=https://upay.skygv.com
mysql_user=sql_f_skygv_com
mysql_passwd=xPFptfy3eDXFFLkX
mysql_database=sql_f_skygv_com
tg_bot_token=YOUR_BOT_TOKEN
api_auth_token=RANDOM_SECURE_TOKEN
forced_usdt_rate=6.4  # Optional

Option 2: phpMyAdmin

Use phpMyAdmin to import the SQL file directly.

👉 Optimize your database performance

3. Configure Epusdt

Modify .env with your domain, database credentials, and Telegram bot details.

4. Set Up Reverse Proxy

Navigate to aaPanel > Website > Reverse Proxy.
Proxy requests from upay.skygv.com to http://127.0.0.1:8000.

5. Grant Execute Permissions

cd /www/wwwroot/upay.skygv.com
chmod +x epusdt

6. Supervisor Configuration

Add a守护进程 command:
/www/wwwroot/upay.skygv.com/epusdt http start

7. Test the Setup

Check Telegram bot responses to confirm Epusdt is running.

8. SSL Configuration

Add certificates in aaPanel’s SSL settings.
Insert this NGINX snippet for HTTP-to-HTTPS redirect:
```
# SSL redirect code here
```
