About PayzCore

PayzCore adds stablecoin payment monitoring (USDT/USDC) to your WHMCS billing system. Accept crypto payments on 5 blockchain networks — TRC20 (Tron), BEP20 (BSC), ERC20 (Ethereum), Polygon, and Arbitrum — with automatic invoice crediting via webhooks.

How It Works

1. Customer views an unpaid invoice and selects PayzCore
2. If multiple networks are available, customer picks their preferred network
3. Customer sees a payment page with wallet address, QR code, exact amount, and countdown timer
4. Customer sends the stablecoin from their wallet
5. PayzCore detects the transfer on the blockchain and sends a webhook
6. The module verifies the signature and credits the WHMCS invoice automatically
