Don’t know the specifics here. What is NIP05 and how would I use it in this situation (Nostrgram is asking for NIP07 compatible)
Discussion
NIP05 is how you connect a domain name to your npub.
If you use guy@guyswann.com as your NIP05 you are proving that the owner of that domain attested to that public key.
I've experienced this also Guy. I just plugged my nsec into Alby and then re-launched nostrgram and approved the connection. It's a bit flaky and slow for me but it is working.
