To incorporate cryptocurrency transactions on a WordPress site, consider using the WooCommerce NowPayments Gateway alongside the WooCommerce plugin. This facilitates diverse payment options for your customers.

Initiate the process by creating an account on NowPayments. Acquire a cryptocurrency wallet, such as Exodus or Coinbase, capable of accepting various cryptocurrencies.

Specify the cryptocurrencies you wish to accept as payment. Set up your API Keys and complete essential account settings. Navigate to the Payments tab in your WooCommerce plugin, adding your IPN secret and API Key. Ensure the NowPayments feature is enabled within the WooCommerce settings. While there are additional steps, they are manageable.
