How do I know or find out that I have NIP-07 extension?
Discussion
Do you use the nostr:npub1getal6ykt05fsz5nqu4uld09nfj3y3qxmv8crys4aeut53unfvlqr80nfm Chrome extension or nos2x?
You'll need to use a web browser extension. Several exist. I use Alby on desktop and nos2x on mobile with the Kiwi browser for Android. If you're on iOS, you can use the Nostore app with Safari.
