## Description

**IronixPay Crypto Payment Gateway for WooCommerce** lets your store accept USDT(
Tether) and USDC (Circle) stablecoin payments across 8 blockchain networks. Price
your products in supported fiat currencies (USD, EUR, CNY, GBP, JPY, KRW, SGD, HKD,
TWD, RUB) — customers pay the equivalent in crypto. No volatility, no chargebacks.

#### Supported Currencies

 * USDT (Tether) — Available on all 8 networks
 * USDC (Circle) — Available on BSC, Ethereum, Polygon, Arbitrum, Base, Optimism,
   Solana

#### Supported Networks

 * TRON (TRC-20) — USDT only
 * BSC / BNB Chain (BEP-20)
 * Ethereum (ERC-20)
 * Polygon (ERC-20)
 * Arbitrum (ERC-20)
 * Base (ERC-20)
 * Optimism (ERC-20)
 * Solana (SPL Token)

#### How It Works

 1. Customer selects “Pay with Crypto” at checkout and chooses a currency and blockchain
    network.
 2. Customer is redirected to a secure IronixPay hosted checkout page.
 3. IronixPay monitors the blockchain for payment and confirms automatically.
 4. Webhook notifies your store — order status updates to “Processing”.
 5. Funds are swept to your treasury wallet.

#### Key Features

 * **Webhook-driven** — HMAC-SHA256 signed callbacks for secure order updates.
 * **WooCommerce Block Checkout** — Full support for the new block-based checkout.
 * **HPOS compatible** — Works with WooCommerce High-Performance Order Storage.
 * **Sandbox mode** — Test with TRON Nile testnet before going live.
 * **Idempotent processing** — Safe against duplicate webhook deliveries.
 * **AML integration** — Blocked payments are flagged and put on hold.
 * **Overpayment handling** — Automatic detection with order notes.

#### Requirements

 * WordPress 5.8+
 * WooCommerce 7.0+
 * PHP 7.4+
 * An IronixPay merchant account ([sign up at ironixpay.com](https://ironixpay.com))

### External services

This plugin connects to the IronixPay API to create cryptocurrency payment checkout
sessions. It is needed to process USDT and USDC stablecoin payments on behalf of
the merchant.

When a customer chooses to pay with crypto at checkout, the plugin sends the order
total, currency, selected cryptocurrency, blockchain network, and order reference
ID to the IronixPay API. The customer is then redirected to a hosted payment page
on IronixPay. No customer personal data (name, email, address) is sent.

IronixPay also sends signed webhook callbacks to your store when a payment is confirmed,
expired, or flagged.

API endpoints used:
 * Production: https://api.ironixpay.com * Sandbox: https://
sandbox.ironixpay.com

## Installation

 1. Upload the `ironixpay-usdt-gateway` folder to `/wp-content/plugins/`, or install
    via **Plugins  Add New  Upload Plugin**.
 2. Activate the plugin through the **Plugins** menu.
 3. Go to **WooCommerce  Settings  Payments  IronixPay – Crypto Payment**.
 4. Enable the gateway, select your environment (Sandbox or Production).
 5. Enter your API Key and Webhook Secret from the [IronixPay Dashboard](https://dashboard.ironixpay.com).
 6. Copy the displayed **Webhook URL** and paste it into your IronixPay Dashboard  
    Webhook settings.

## FAQ

### What currencies can I accept?

USDT (Tether) and USDC (Circle). You can enable one or both in the plugin settings.
USDC is available on all networks except TRON (where only USDT is supported).

### What currency are products priced in?

Products are priced in your store’s default currency (e.g., USD, EUR). The order
total is sent to IronixPay’s API which handles the conversion. If your store currency
is already USDT/USDC, it’s a 1:1 settlement.

### Can I price products in fiat currencies?

Yes! The following fiat currencies are supported: USD, CNY, EUR, GBP, JPY, KRW, 
SGD, HKD, TWD, and RUB. The order total is sent to the IronixPay API, which converts
it to the selected cryptocurrency at the current market rate. If your store uses
a different currency, the IronixPay payment option will not appear at checkout.

### Is there a minimum payment amount?

Yes, the minimum payment is approximately 1 USDT/USDC equivalent. The exact minimum
is validated by the IronixPay API at checkout.

### What happens if the customer overpays?

Overpayments are detected automatically. The order is marked as paid with a note
indicating the overpaid amount. Excess funds can be managed via the IronixPay Dashboard.

### What happens if the payment session expires?

If no payment is received within the time limit, the order is marked as “Failed”
with an appropriate note. Any partial payments are noted for resolution via the 
IronixPay Resolution Center.

### How does the webhook verification work?

Each webhook request includes an `X-Signature` header (HMAC-SHA256) and an `X-Timestamp`
header. The plugin verifies the signature using your Webhook Secret and rejects 
requests with timestamps older than 5 minutes (anti-replay protection).

### Does this plugin support the new WooCommerce Block Checkout?

Yes! The plugin fully supports both the classic shortcode checkout and the new block-
based checkout introduced in WooCommerce 8.3+.

### Can I test before going live?

Yes. Set the environment to “Sandbox” and use your test API key. Sandbox mode uses
the TRON Nile testnet. Note: USDC is not available in Sandbox mode.
