Customers can pay with Bitcoin, Ethereum( ERC-20), BNB Smart Chain (BEP-20), and Tron (TRC-20) tokens. Payments are sent to wallet addresses generated by your ForgeLayer account — ForgeLayer does not custody or control merchant funds. #### Key Features * **Multiple networks** — Bitcoin, Ethereum, BSC, and Tron supported out of the box. * **50+ tokens** — USDT, USDC, DAI, LINK, UNI, AAVE, CAKE, and dozens more with automatic price conversion via CoinGecko. * **Instant webhook confirmation** — HMAC-SHA256 signed webhooks trigger order fulfillment in real time, no polling required. * **Background price caching** — WP-Cron keeps cryptocurrency prices fresh so checkout never calls an external API on page load. * **WooCommerce Blocks compatible** — fully supports the block-based Cart and Checkout pages alongside the classic shortcode checkout. * **HPOS compatible** — officially declared compatible with WooCommerce High-Performance Order Storage. * **Address reuse** — optionally reuse inactive addresses to conserve your plan’s address quota. * **Late payment grace period** — configurable window to auto-reopen cancelled orders when payment arrives after the deadline. * **Plan usage dashboard** — real-time usage bars for addresses, webhooks, and API requests right on the settings page. Email alerts at 80%, 90%, and 100%. * **Security hardened** — HMAC signature verification, nonce CSRF protection, rate limiting on AJAX endpoints, progressive IP lockout, replay-attack prevention, input whitelisting, and comprehensive HTTP security headers on the payment page. * **Non-custodial** — ForgeLayer never holds your funds. Crypto goes straight to your wallet. #### Supported Networks and Tokens Network Native Coin Example Tokens Bitcoin BTC — Ethereum ETH USDT, USDC, DAI, LINK, UNI, AAVE, WBTC BNB Smart Chain BNB USDT, USDC, BUSD, CAKE, XVS, WBNB Tron TRX USDT, USDC, BTT, WIN, JST, SUN Custom CoinGecko IDs can be added in settings for any token not in the built-in directory. #### How It Works 1. A customer selects a network and token at checkout. 2. ForgeLayer generates a unique deposit address for the order. 3. The customer sends the exact crypto amount to the displayed address (with QR code). 4. ForgeLayer fires a signed webhook when the deposit is confirmed on-chain. 5. The WooCommerce order status moves to Processing automatically. #### Security This plugin implements defense-in-depth security: * All webhook payloads are verified with HMAC-SHA256 signatures before any processing. * Transaction hashes are deduplicated to prevent replay attacks. * Webhook payload timestamps are validated within a ±5-minute window. * Admin AJAX endpoints are rate-limited (max 10 requests/minute per user). * The payment poll endpoint uses IP-based progressive lockout (3 strikes = 60s, 10 strikes = 1h). * The payment page sends `X-Content-Type-Options`, `X-XSS-Protection`, `Referrer- Policy`, and a tight `Content-Security-Policy` header. * All input is validated against strict whitelists before use. * No sensitive data (API key, webhook secret, address IDs) is ever output in HTML source. ### External services This plugin connects to the following external services: #### ForgeLayer API (api.forgelayer.io) Used for all core payment functions: generating blockchain deposit addresses, registering webhooks, and verifying payment confirmations. The store’s ForgeLayer API key and order-related data (amount, currency, chain, token) are sent when a customer initiates checkout. This service is required for the plugin to function. * [ForgeLayer Terms of Service](https://forgelayer.io/terms) * [ForgeLayer Privacy Policy](https://forgelayer.io/privacy) #### CoinGecko (api.coingecko.com) Used to fetch current cryptocurrency prices for fiat-to-crypto conversion. Only coin IDs and the store’s fiat currency are sent — no customer or order data is transmitted. Prices are cached server-side by WP-Cron; CoinGecko is not called during individual customer checkouts under normal operation. * [CoinGecko Terms of Service](https://www.coingecko.com/en/terms) * [CoinGecko Privacy Policy](https://www.coingecko.com/en/privacy) #### QRServer (api.qrserver.com) — optional Used to generate QR code images on the payment page. **Disabled by default.** Merchants can enable it under WooCommerce > Settings > Payments > ForgeLayer > Show QR Codes. When enabled, the blockchain wallet address (not customer personal data) is sent to api.qrserver.com to render a QR image. * [QRServer Terms of Service](https://goqr.me/de/rechtliches/agb-logo.html) * [QRServer Privacy Policy](https://goqr.me/de/rechtliches/datenschutz-goqrme.html) ## Installation 1. **Upload** the `forgelayer-woocommerce` folder to the `/wp-content/plugins/` directory, or install via the WordPress plugin installer. 2. **Activate** the plugin through the Plugins screen in WordPress. 3. Go to **WooCommerce > Settings > Payments** and click **ForgeLayer Crypto Payments**. 4. **Enter your API key** — get one at [forgelayer.io/dashboard](https://forgelayer.io/dashboard). Use a `flk_test_` key to test in sandbox mode. 5. **Enable chains** — check the Bitcoin, Ethereum, BSC, and/or Tron checkboxes. 6. **Refresh Token List** — click the button to pull your configured tokens from ForgeLayer. 7. **Setup Webhook** — click **Setup Webhook** to register your store’s endpoint with ForgeLayer automatically. 8. **Save settings** and make a test purchase. #### Minimum Requirements * WordPress 5.8+ * WooCommerce 6.0+ * PHP 7.4+ * An active [ForgeLayer](https://forgelayer.io) account ## FAQ ### Do I need a ForgeLayer account? Yes. ForgeLayer manages the blockchain address infrastructure, balance monitoring, and webhook delivery. Create a free account at [forgelayer.io](https://forgelayer.io) to get your API key. ### Where do customer payments go? Payments are sent to wallet addresses generated by your ForgeLayer account. ForgeLayer does not custody or control merchant funds — you retain full ownership of your private keys and wallet balances. You can transfer funds to any external wallet directly from your ForgeLayer dashboard. ### Does the plugin support the new WooCommerce block-based checkout? Yes. The plugin is fully compatible with both the classic shortcode checkout and the WooCommerce Blocks (Gutenberg) Cart and Checkout pages. ### What happens if a customer pays after the order timer expires? If **Accept Late Payments** is enabled (the default), orders are automatically reopened when payment arrives within your configured grace period (default 60 minutes). Payments that arrive beyond the grace period trigger an admin email for manual review — the funds are still in your ForgeLayer wallet. ### How do I add a token that is not in the built-in list? 1. Add the token to your ForgeLayer account via the dashboard. 2. In WooCommerce > Settings > Payments > ForgeLayer, click **Refresh Token List**. 3. If the token needs price conversion, find its CoinGecko ID (the slug in the URL on coingecko.com) and add it to the **Custom CoinGecko IDs** field in the format` SYMBOL|coingecko-id`. ### Is the plugin compatible with WooCommerce HPOS (High-Performance Order Storage)? Yes. The plugin has been tested with HPOS and declares compatibility via the WooCommerce FeaturesUtil API. All order data is read and written through WooCommerce’s order API, not raw database queries. ### How can I test the integration without real crypto? Generate a `flk_test_` API key from your ForgeLayer dashboard, enter it in settings, and enable **Sandbox / Test Mode**. Test transactions do not require real funds. ### What should I do if the price shows “Calculating…” at checkout? This means the WP-Cron price cache has not been populated yet. Save your settings to trigger an immediate cache warm, or wait for the next cron run (default 5 minutes). You can also verify WP-Cron is running correctly on your host. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “ForgeLayer Crypto Payments for WooCommerce” is open source software.
