Not good compared to bitpay plugin. 1. The orders are stuck in "on hold" status. They don't send confirmation for sure. It is broken. 2. Spectrocoin gateway page does not allow to copy paste bitcoin address and value for people who want to pay from their wallet application on a website or software.

Features Needed ----------------------------------- 1) No option to show company logo on the payment page. 2) Real name in your account is shown on payment page even if you are a business. 3) Default conversion currency is EUR. 4) No option to select the timeout period. It defaults to 24 hours which can lead to inventory being in limbo awaiting payment before it fails. 5) No overpayment or underpayment handling. 6) No ability to hide the language translations, select alternate ones, or choose a default language. Bugs/Issues ----------------------------------- Gateway can take 10 seconds before showing the payment options. Not sure if this is a plugin, or server issue. Probably a server issue.

Contributors & Developers

“Bitcoin Payment Extension for WP WooCommerce” is open source software. The following people have contributed to this plugin.

Fixed: Corrected a typo in the plugin’s description. Changed “aplugin” to “a plugin” for better clarity.

Added: Included a link to access SpectroCoin plugin settings directly from the plugin page. This enhancement provides users with easier access to the configuration options.

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

Improved: In the WC_Gateway_Spectrocoin class, made changes to prevent deprecated messages related to the creation of dynamic properties.
