No, our payment gateway allows users to accept cryptocurrencies only. Though, our merchants can automatically convert all payments that are received via our payment gateway to any other supported currencies on Spectrocoin (FIAT currencies included).

What fees do I have to pay in order to use your cryptocurrency payment gateway?
Every merchant payment will be counted up to 1%. The percentage depends on the type of business and the frequency of payments. There are no other setup or maintenance fees when using our payment gateway!

I want to start accepting cryptocurrencies on my website, what are the steps that I have to take?
In order to integrate our crypto payment gateway our clients have to go through a few simple steps: create an account, verify it, create a merchant project and use its details to connect it to the website where you want to start accepting cryptocurrencies.

Updated: Implemented an “if” statement to handle compatibility with older PHP versions (PHP 8 and below) for the function openssl_free_key($public_key_pem). This change is necessary as PHP 8
deprecates openssl_free_key and now automatically destroys the key instance when it goes out of scope. (Source: https://stackoverflow.com/questions/69559775/php-openssl-free-key-deprecated)

This update is particularly important for PHP version 8.2 and above.

If the user deletes or deactivates WooCommerce, a notice will be displayed, and the SpectroCoin plugin will be deactivated automatically.

Added: Enhanced the style of the admin’s payment settings window to match the design of SpectroCoin.com, providing a more cohesive user experience.

Added: Introduced an informative message on the admin page, guiding users on how to obtain the mandatory credentials required for using the SpectroCoin plugin effectively. This addition helps users easily find the necessary information for setup and configuration.
