Coil by Coil

Coil led an open standard called Web Monetization. This is a brand-new standards proposal and not many websites support it yet. But it enables some amazing new experiences.

This extension only validates if your website has Web Monetization enabled.

Coil's extension is open source. You can view the source code on Github here: https://github.com/coilhq/web-monetization-projects/tree/main/packages/coil-extension
