Just sent a zap with it, so yes.
Discussion
Last I tried, I had to make a new nsec because I wasn't able to import my own.
I didnt import my nsec, just used it to send zap on nostr, it worked. But i still have coinos set to receive on nostr.
i downloaded fedi and played around with it but i didn't see what it adds.
so you use a nostr client inside fedi, and the zaps happen from your fedi wallet ? i remember there being a built-in browser, is that how your are using nostr with fedi ?
