GriffNode is non-custodial: we never hold, touch, or can freeze your funds. There are no chargebacks. You connect your wallet’s extended public key (xPub) once at [griffnode.com](https://griffnode.com/), and a fresh receiving address is derived for every payment, so funds go customer to you directly. **Add a pay button with one shortcode:** ``` [griffnode_button amount="49" reference="order-123"] ``` Optional attributes let you lock to one coin, pre-fill the customer email, or set success and cancel URLs. Full options are in the [documentation](https://docs.griffnode.com/). **Why accept crypto this way** * **Non-custodial**: funds settle directly to your wallet, not ours. We literally cannot spend or freeze them. * **No chargebacks**: on-chain settlement is final. No clawbacks weeks after you deliver. * **Live in minutes**: sign up, paste your xPub, drop in the shortcode. * **Works anywhere**: posts, pages, sidebars, any theme. No WooCommerce, no store required. For WooCommerce stores, use our separate GriffNode for WooCommerce plugin. * **Flat monthly pricing**: no percentage per transaction. See [pricing](https://griffnode.com/). **Coins supported** Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC), Dogecoin (DOGE), Dash (DASH), plus the ERC-20 stablecoins **USDT, USDC and DAI** for price-stable payments. **Features** * `[griffnode_button]` shortcode with a live coin selector and a hosted, mobile- friendly payment page (BIP-21 QR code). * Real-time on-chain confirmation via signed webhooks (HMAC-SHA256). * Handles completed, partial and expired payment events. * Settings screen for your API keys and the webhook URL. A GriffNode account and API keys are required (see External services below). ### External services This plugin relies on the GriffNode API (`api.griffnode.com`), operated by GriffNode, to create crypto payment sessions and to confirm payments. It is not optional: the plugin cannot function without it. **What is sent, and when:** * When a page with the `[griffnode_button]` shortcode loads, the visitor’s browser fetches the list of cryptocurrencies you have configured wallets for from the API endpoint `api.griffnode.com/merchant/cryptos`, authenticated with your Publishable Key (safe to expose, it grants no write access). This request reveals the visitor’s IP address to GriffNode. * When a visitor clicks the pay button, your site sends the amount, fiat currency, chosen cryptocurrency, your site URL, the button’s reference, and (if you set them in the shortcode) the customer email and success/cancel URLs to the API endpoint `api.griffnode.com/transactions/create`, authenticated with your Secret Key. The visitor is then redirected to the GriffNode hosted payment page. * While any payment made through your site is open (at most 7 days), your site sends the IDs of those open payments to the API endpoint `api.griffnode.com/transactions/ list` every 30 seconds, authenticated with your Secret Key, to read their status. It stops when no payment is open. * When the payment status changes, GriffNode sends a signed webhook to your site at `/wp-json/griffnode/v1/webhook`. The plugin verifies the HMAC-SHA256 signature before acting on it.

The griffnode_webhook action was not affected. * The status check is scheduled only once a payment is open, never while WordPress is still loading, which fixes an early translation-loading notice with WooCommerce on non-English sites. #### 1.0.3 * Webhook signature check no longer uses str_starts_with(), so nothing in the plugin needs PHP 8. #### 1.0.2 * Works on every GriffNode plan. Without a webhook (free Starter plan) the plugin checks all open payments every 30 seconds in one request and fires the same griffnode_payment_* actions (with source = api_check). It does not depend on site visitors, and stops when no payment is open. * Each payment event fires once, whether it arrives by webhook, by status check, or both. Webhook replays older than 48 hours are refused. * New actions: griffnode_payment_paid_late and griffnode_payment_needs_review ( coins arrived after the window, or need a manual decision in your GriffNode dashboard). * Payments are followed for up to 7 days: slow confirmations, partial payments topped up later and late payments you confirm still arrive. * Admin notice when status checks fail (for example a wrong Secret Key). * Fixed: non-USD buttons were charged in USD (the currency was sent under the wrong field name). * Fixed: the transaction id returned after creating a payment was always empty. * Fixed: a fatal error when this plugin and GriffNode for WooCommerce were active together. #### 1.0.1 * Renamed to GriffNode Crypto Payments. * Pay button script is now a properly enqueued file, loaded only on pages that show a button. * The cryptocurrency list is built safely with DOM methods and fetched once per page. * Documented the external services the plugin uses. #### 1.0.0 * Initial release: shortcode-based non-custodial crypto payments for any WordPress site (BTC, ETH, LTC, DOGE, DASH + USDT/USDC/DAI), hosted checkout, signed webhooks. ## Meta * Version **1.0.4** * Last updated **7 hours ago** * Active installations **Fewer than 10** * WordPress version ** 6.0 or higher ** * Tested up to **7.1.4** * PHP version ** 7.4 or higher ** * Tags * [bitcoin](https://wordpress.org/plugins/tags/bitcoin/)[crypto payments](https://wordpress.org/plugins/tags/crypto-payments/) [cryptocurrency](https://wordpress.org/plugins/tags/cryptocurrency/)[ethereum](https://wordpress.org/plugins/tags/ethereum/) [payments](https://wordpress.org/plugins/tags/payments/) * [Advanced View](https://wordpress.org/plugins/griffnode-crypto-payments/advanced/) ## Ratings No reviews have been submitted yet.
