If you are just looking for interoperability and being able to withdraw from ZBD, I have had great success with the nostr:npub12vkcxr0luzwp8e673v29eqjhrr7p9vqq8asav85swaepclllj09sylpugg built in wallet.

I also don’t get enough sats from ZBD or Fountain that I am not alright zapping them. So convenient enough to send to Nostr. #v4v
