Then I checked out numbnoot by Gandlaf, which gives a great interactive overview of how it all works: https://numbnoot.gandlaf.com

Then I started diving in to the cashu-ts library, but if you are not a developer, then probably the good next steps are:

1) Register an Nostrly or npub.cash nickname, use it as your Nostr Lightning address. That way your zaps will appear as Cashu tokens.

2) You can then withdraw the tokens to a wallet, like Cashu.me. Or use my tool to send them elsewhere as needed.

3) If you use Cashu.me, you can then connect it back to your Nostr client using NWC.

That way, you can play with receiving, holding and spending / xapping with ecash. You can even send ecash tokens to people by DM or email.

Ecash is cool 😉
