is there any way to use the CLN on Start9 to be able to send and receive zaps on nostr? I am just starting out and trying to see what I can and cant do without having to be on a custodial wallet.
In order to send zaps on Nostr using your CLN node on StartOS you could set up Alby using this guide.
Once the Alby browser extension is set up you can use it to act like a bridge between your Node and your preferred Nostr client by importing your Nostr Public Key.
Make sure to give the extension a secure password and even setting up specific daily budgets so no crazy spending can go on without you noticing.
It is also recommended to backup your Alby recovery phrase in case something goes wrong.
Also check out Nostr Wallet Connect, which was just released. This should make linking all these services easier.
