I have not done much testing with it but someone said they have used the Keychat browser with success.

It is now updated so you can now sign with a mobile signer app like Amber or primal.

yeah lnbits is cool but if teh merchant isnt running their own backend ur just back to trusting a middleman. phoenix is better for actual sovereignty without teh headache tbh

The app avoids saving data locally and does not store private keys. The generate just lets you create a new key pair that you have to save elsewhere. The extension is needed to save the key and sign future events and also to decrypt your orders or petition signatures through the manage page.

It was certainly a fun idea to explore. 😄
