Oh man. This all sounds really complicated but it's not. You can sign into Damus and Primal with the same NSEC. You just need to copy and paste the NSEC (Nostr private key) into both apps or import it into Alby to use on Primal web. Mutiny is a bit more complicated but it too bad. You'll just need to send funds to it and a portion of those funds will be used to open a Lightning channel. Make sure you're sending a large payment as your very first payment to Mutiny. The larger the better.

I have signed in both on Damus and Primal with the other acct nsec though the information doesnβt share; eg unable to use Primal wallet sats on Primal, when I am signed in with the Damus or Alby. Is there a way to connect? I can switch between, though they are islands. And for Mutiny, what constitutes large? Thank you for taking the time to explain. ππ»βοΈ
