Setting Up USDT Payments for Unicorn Digital Card with Docker: A Complete Guide

Introduction

Following our previous tutorial on building a digital storefront with Docker, we now dive into integrating USDT cryptocurrency payments. This guide provides a secure, step-by-step approach to accepting decentralized payments while avoiding sensitive financial services.

Key Features

• Cryptocurrency Integration: Accept USDT (Tether) payments seamlessly
• Docker-Based Deployment: Containerized for easy setup and maintenance
• Telegram Bot Notifications: Real-time payment alerts
• Secure Architecture: Isolated services with proper authentication

Technical Requirements

Server Specifications

• Recommended Provider: US-based servers (avoid Chinese hosting for crypto payments)
• Minimum RAM: 1GB (sufficient for Docker operations)
• Operating System: Debian 11/Ubuntu LTS

Essential Components

1. Docker & Docker-Compose
2. Domain name with proper DNS resolution
3. Telegram account (for bot notifications)

Implementation Guide

1. Docker Environment Setup

sudo -i
mkdir -p /root/data/docker_data/epusdt
cd /root/data/docker_data/epusdt

2. Docker-Compose Configuration

Create docker-compose.yml with these parameters:

version: "3"
services:
  db:
    image: mariadb:focal
    environment:
      - MYSQL_ROOT_PASSWORD=your_secure_password
      - MYSQL_PASSWORD=user_secure_password

  epusdt:
    image: stilleshan/epusdt
    ports:
      - 8000:8000

3. EPUSDT Configuration

Configure epusdt.conf with:

1. Your domain URI
2. MySQL credentials
3. Telegram bot token (from @BotFather)
4. Admin user ID
5. API authentication token

4. Database Initialization

docker exec -i epusdt-db-1 sh -c 'exec mysql -uepusdt -puser_password epusdt' < epusdt.sql

Payment Gateway Integration

For Unicorn Digital Card:

1. Navigate to Payment Configuration
2. Enable EPUSDT gateway

3. Set parameters:

   • Merchant ID: Your MySQL password
   • API Endpoint: https://yourdomain.com/api/v1/order/create-transaction

Maintenance Operations

Updating the Service

cd /root/data/docker_data/epusdt
docker-compose pull
docker-compose up -d
docker image prune

Complete Uninstallation

docker-compose down
rm -rf /root/data/docker_data/epusdt

Security Best Practices

• Regularly rotate API tokens and database credentials
• Implement HTTPS via Nginx Proxy Manager
• Monitor Telegram bot access
• Maintain server security updates

Q: How secure are cryptocurrency payments?

A: When properly configured with HTTPS and secure credentials, USDT transactions provide blockchain-level security.

Q: Can I use this with other cryptocurrencies?

A: This specific implementation is for USDT, but similar architectures can support other coins.

Conclusion

This implementation brings cryptocurrency acceptance to your digital store with enterprise-grade security. The Docker architecture ensures easy maintenance while the Telegram integration provides real-time notifications.
