How It Works

1. Admin creates a payment profile for PayzCore with API key and webhook secret
   
2. User selects "Pay with Stablecoin" when purchasing an upgrade, then picks network/token
   
3. Add-on creates a monitoring request via the PayzCore API
   
4. User sees payment page with wallet address, QR code, and countdown timer
   
5. PayzCore watches the blockchain and sends a webhook when payment is detected
   
6. User upgrade is activated automatically
