Description
Gate Comments with Bitcoin Payments!
Monetise your blog’s comment section by requiring a small Bitcoin or Lightning Network micropayment before a comment is published. When a visitor submits a comment, a payment modal appears inline. Once payment is confirmed via webhook, the comment is automatically approved and appears on the post � no manual moderation needed.
Payment processing is handled securely via Coinsnap or your own BTCPay Server.
Requirements:
- A WordPress website (version 6.0 or higher)
- The Coinsnap Comment Payments with Bitcoin plugin
- A Coinsnap account or your own BTCPay Server
Key Features:
- Per-Post-Type Amounts � Set a different payment amount (in satoshis) for posts, pages, WooCommerce product reviews, and any custom post type.
- Two Payment Providers � Use Coinsnap (no server required) or self-hosted BTCPay Server.
- Inline Payment Modal � The Coinsnap checkout appears directly on the page; no redirect, no friction.
- Real-time Status Polling � The modal polls the payment status and publishes the comment automatically on confirmation.
- Webhook Verification � Incoming webhook payloads are verified with HMAC signature checking.
- Admin & Author Notifications � Receive email confirmation the moment a comment payment settles. Optionally notify the comment author too.
- Honeypot Anti-spam � A hidden field silently blocks bots before any payment logic runs.
- Rate Limiting � Configurable per-IP rate limit prevents abuse.
- Credential Sharing � Automatically inherits API keys from other installed Coinsnap plugins (WooCommerce, Booking Form, Donation, Invoice Form) so you never configure the same credentials twice.
- Modern Admin UI � Card-based settings page with connection status badge, provider toggle, and BTCPay setup wizard.
Two Operating Modes:
- Coinsnap � Sign up at app.coinsnap.io, get your Store ID and API Key, and you’re ready. No server required.
- BTCPay Server � Connect to your own BTCPay Server using the one-click API Key generation wizard.

FAQ
-
Do I need a Coinsnap account?
-
You can use either a free Coinsnap account or your own BTCPay Server. At least one is required.
-
Where do I find my Store ID and API Key?
-
Log in to app.coinsnap.io, navigate to Store Settings � your Store ID and API Key are listed there.
-
What currency is used for the payment amount?
-
Amounts are specified in satoshis (sats), the smallest unit of Bitcoin.
-
Do I need to configure credentials if I already use another Coinsnap plugin?
-
No. If another Coinsnap plugin (WooCommerce, Booking Form, Donation, or Invoice Form) is already installed and configured, this plugin will automatically inherit its credentials.
-
Will existing comments be affected?
-
No. The payment gate only applies to new comment submissions after the plugin is activated and amounts are configured.
-
What happens if a payment is never completed?
-
The comment stays in a pending/unpaid state and will not be published. You can manually approve it from the WordPress Comments admin screen if needed.
-
Can I exclude certain post types?
-
Yes. Each post type must be explicitly enabled in the Per-Post-Type Settings card. Post types with no amount set (or set to 0) are not gated.
-
Does this work with WooCommerce product reviews?
-
Yes. Enable the WooCommerce post type in Per-Post-Type Settings and set an amount. A payment badge is added below the review form to inform customers.
