[![WordPress.org](https://img.shields.io/badge/WordPress.org-Plugin_Directory-blue)](https://wordpress.org/plugins/payzcore-for-woocommerce/) [![Docs](https://img.shields.io/badge/Docs-docs.payzcore.com-cyan)](https://docs.payzcore.com/integrations/woocommerce)

Accept USDT and USDC stablecoin payments in your WooCommerce store via PayzCore blockchain transaction monitoring across multiple networks (TRC20, BEP20, ERC20, Polygon, Arbitrum).

PayzCore is a **non-custodial** monitoring service. It watches blockchain addresses for incoming stablecoin transfers and sends webhook notifications when transactions are detected. PayzCore does not hold, transmit, or custody any funds.

## Important

**PayzCore is a blockchain monitoring service, not a payment processor.** All payments are sent directly to your own wallet addresses. PayzCore never holds, transfers, or has access to your funds.

- **Your wallets, your funds** — You provide your own wallet (HD xPub or static addresses). Customers pay directly to your addresses.
- **Read-only monitoring** — PayzCore watches the blockchain for incoming transactions and sends webhook notifications. That's it.
- **Protection Key security** — Sensitive operations like wallet management, address changes, and API key regeneration require a Protection Key that only you set. PayzCore cannot perform these actions without your authorization.
- **Your responsibility** — You are responsible for securing your own wallets and private keys. PayzCore provides monitoring and notification only.

- WordPress 5.8 or later
- WooCommerce 7.0 or later
