Is this Vlad? I'm in your discord if someone from the team can drop a mention of this npub for Nostr. Or, we can help walk you through setting up a nip05 identifier for the Kagi domain.

On your website post a nostr link to your npub. Maybe combined with njump. i.e. Https://njump.me/npub123etc

You could use a nostr logo by nostr:npub18nagz6a53yh6d05e8trj487dhvyfhh4qchvsz87jqng4g4zl5tvs825evl

The BEST was would be better to setup a Nostr address with your domain. It's just one line of code.

Otherwise, you can just add a link to your Nostr profile on your website somewhere that is applicable.
