PayzCore

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.
<ul>
<li>Your wallets, your funds — You provide your own wallet (HD xPub or static addresses). Customers pay directly to your addresses.</li>
<li>Read-only monitoring — PayzCore watches the blockchain for incoming transactions and sends webhook notifications. That’s it.</li>
<li>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.</li>
<li>Your responsibility — You are responsible for securing your own wallets and private keys. PayzCore provides monitoring and notification only.</li>
</ul>
How It Works
PayzCore is a non-custodial blockchain transaction monitoring service. When a customer checks out, the plugin creates a monitoring request via the PayzCore API. The customer is shown a unique wallet address and QR code. PayzCore watches the blockchain for incoming transfers and sends a webhook notification when the payment is detected, automatically updating your WooCommerce order status.
Key Features
<ul>
<li>Accept USDT and USDC stablecoins</li>
<li>Multi-network support: TRC20 (Tron), BEP20 (BNB Smart Chain), ERC20 (Ethereum), Polygon, and Arbitrum</li>
<li>Non-custodial: funds go directly to your wallet, PayzCore never touches them</li>
<li>Static wallet mode: use a fixed address for all payments with customer tx hash confirmation</li>
<li>Real-time payment status polling with automatic order updates</li>
<li>Dark-themed payment instructions page with QR code and countdown timer</li>
<li>HMAC-SHA256 webhook signature verification for security</li>
<li>Automatic order completion for virtual/downloadable products</li>
<li>Blockchain explorer links in order notes (Tronscan, BSCScan, Etherscan, Polygonscan, Arbiscan)</li>
<li>WooCommerce HPOS (High-Performance Order Storage) compatible</li>
<li>Translatable with full i18n support</li>
</ul>
Static Wallet Mode
By default, PayzCore derives a unique HD wallet address for each payment. If you prefer to use a single fixed address for all payments, you can enable Static Wallet Mode:
<ol>
<li>Go to WooCommerce > Settings > Payments > PayzCore (Stablecoin)</li>
<li>Enter your wallet address in the “Static Wallet Address” field</li>
<li>Save settings</li>
</ol>
When static wallet mode is active:
<ul>
<li>All payments use the same address you configured</li>
<li>The payment amount includes a micro-offset (e.g., $50.003 instead of $50.00) to distinguish transactions</li>
<li>Customers see a notice with the exact amount to send</li>
<li>After sending payment, customers are shown a form to paste their blockchain transaction hash (TxID)</li>
<li>The transaction hash is submitted to PayzCore for verification</li>
<li>Order status is updated automatically once PayzCore confirms the transaction</li>
</ul>
This mode is useful when you want to receive all payments to a single address without setting up HD wallet (xPub) derivation.
Requirements
<ul>
<li>A PayzCore account at <a href="https://payzcore.com" rel="nofollow ugc">payzcore.com</a></li>
<li>A project with an API key and webhook secret configured</li>
<li>WooCommerce 7.0 or higher</li>
<li>PHP 7.4 or higher</li>
<li>WordPress 5.8 or higher</li>
</ul>
Before Going Live
Always test your setup before accepting real payments:
<ol>
<li>Verify your wallet — In the PayzCore dashboard, verify that your wallet addresses are correct. For HD wallets, click “Verify Key” and compare address #0 with your wallet app.</li>
<li>Run a test order — Place a test order for a small amount ($1–5) and complete the payment. Verify the funds arrive in your wallet.</li>
<li>Test sweeping — Send the test funds back out to confirm you control the addresses with your private keys.</li>
</ol>
Warning: Wrong wallet configuration means payments go to addresses you don’t control. Funds sent to incorrect addresses are permanently lost. PayzCore is watch-only and cannot recover funds. Please test before going live.

<h3>Third Party or External Service</h3>
This plugin connects to the <a href="https://api.payzcore.com" rel="nofollow ugc">PayzCore API</a> to create and monitor blockchain payment requests. The PayzCore API is required for this plugin to function.
When data is sent:
<ul>
<li>When a customer places an order and selects PayzCore as the payment method, a monitoring request is created via the API.</li>
<li>While the customer is on the payment instructions page, the plugin polls the API every 15 seconds to check payment status.</li>
<li>If using static wallet mode, the customer’s submitted transaction hash is sent to the API for verification.</li>
<li>When the admin clicks “Test Connection” in plugin settings, the plugin fetches project configuration from the API.</li>
</ul>
Data transmitted:
<ul>
<li>Order amount, selected blockchain network and token</li>
<li>Customer identifier (order ID or email, used as external reference)</li>
<li>Store webhook URL (for receiving payment status notifications)</li>
<li>Transaction hash (static wallet mode only)</li>
</ul>
No data is sent unless the plugin is enabled and configured with an API key. PayzCore does not hold, transmit, or custody any funds — it is a read-only monitoring service.

This plugin also displays links to third-party blockchain explorers so users can verify their transactions on the blockchain. No data is sent to these services by the plugin — they are informational links only, opened in the user’s browser.
