Welcome @6ad3e2a348!

@Undisciplined was right on nostr, we haven't made onboarding easy yet, especially attaching a wallet to send & receive sats. This is currently my focus (maybe I'll share our whiteboard session regarding it later today in ~meta).

The easiest option to start receiving sats is to enter a lightning address here. Many (custodial) wallets provide one, for example Strike or Wallet of Satoshi.

I can also recommend checking out the FAQ, it should answer at least basic questions about credits vs sats.

Let me know if you have any other questions!
