On Chain Wallets can receive funds without an invoice, correct? Like people can just send BTC to your wallet address. Do you have to have a set invoice amount to receive via lightning? Can people just send you any amount? Is this why you need something like Alby or a primal lighting wallet? I did set a Mutiny Wallet and that seemed to work with NWC to receive funds of any amount but then what is the lighting address associated with that Mutiny Wallet? The addresses confuse me. #asknostr #bitcoin #lightning #onchain

On-chain addresses don't need an invoice; they can be paid spontaneously.

Lightning doesn't naturally support spontaneous payments, but there are a couple workarounds, including: keysend payments (pay to a node public key), zero-amount invoices (replace the amount with a different number), bolt12 (negotiate via onion messages between nodes),and lightning address (communicate with a server for a specific invoice).

We created Ghost Payments as part of nostr:npub19tcpurtt6xulhw0r6sc404j9jraj0h8me2lzs7z2tqewz7l0hpas59nlea which enables a central lightning address server for all lightning nodes to use. It's a trusted setup, but enables nodes to receive spontaneous payments without running a separate lightning address server.
