Crypto Payment Gateway

Crypto Payment Gateway Pro+ — Accept BTC, ETH, LTC, USDT (ERC20/TRC20) & BNB in seconds

Crypto Payment Gateway Pro+ is a self-hosted, premium web app that lets you create instant, wallet-ready crypto payment requests with real-time conversion from USD/EUR. Enter a fiat amount, pick a coin, and the app returns the exact crypto amount, a standards-based payment URI (when supported), and a scannable QR code enhanced with a coin badge for a professional look.

Built with Flask (Python) and a dark, responsive UI, Pro+ is lightweight, fast, and easy to customize. Ideal for freelancers, online sellers, and small businesses that want to accept crypto without middlemen.

Highlights

• 💱 Live FX: Converts USD/EUR → BTC, ETH, LTC, USDT (ERC20/TRC20), BNB using up-to-date market rates
• 📸 QR codes with coin badge for clean, trustworthy payment screens
• 🔗 Standard URIs where available (BIP-21 for BTC/LTC, EIP-681 for ETH)
• 🧩 Simple config via config.json or environment variables
• 🎨 Premium dark UI (Bootstrap 5), mobile-friendly
• 🛠 Self-hosted: no custodial service, no tracking
• ⚙️ No database: drop-in, portable, easy to deploy

Note: For ERC20/TRC20/BNB, the QR encodes the address (widely supported by wallets) and shows the exact amount separately. ETH native uses EIP-681 with wei for precise values.
