Accept crypto in WooCommerce

A free payment-gateway plugin for WooCommerce. The customer places an order, pays on a hosted checkout page, and your store is marked paid by a signed webhook - no card data, no crypto handling on your server.

What you need

  • A SwapSS Pay merchant account - registration is free and self-serve.
  • An API key and webhook secret from the merchant dashboard.

Built the safe way

  • Redirect-based hosted checkout: no sensitive data touches your server.
  • Every webhook is HMAC-SHA256 signed and replay-protected; payment truth never rides a browser redirect.
  • Invoice creation is idempotent - a retry cannot create a duplicate charge.
