Accept Tezos with Payzos Wordpress plugin

You will need Woocommerce plugin as well. Activate this plugin then set your XTZ address in Payments > Payzos > Manage.

I used Claude Code to revive the Payzos plugin and hopefully address the security issues that saw it unlisted from Wordpress plugins.

This plugin is provided as-is. No responsibility taken for any bugs or financial loss. I credit Johan Peterson as the original author of the code.
