Probably the simplest way to get a LNURL and both receive and send zaps (which are basically bitcoin lightning “tips”) is to use the nostr:npub12vkcxr0luzwp8e673v29eqjhrr7p9vqq8asav85swaepclllj09sylpugg client iOS app. It comes with a built-in lightning wallet and will give you a LNURL (which will look like an email address). Primal will ask for personal info when you first use it but you can use fake info (although use an email you can at least access). If you don’t mind using a custodial lightning wallet (i.e. one where you should only keep a small amount of Satoshi’s because, like a bank, they control the wallet, not you) then research nostr:npub1getal6ykt05fsz5nqu4uld09nfj3y3qxmv8crys4aeut53unfvlqr80nfm and nostr:npub1hcwcj72tlyk7thtyc8nq763vwrq5p2avnyeyrrlwxrzuvdl7j3usj4h9rq (I don’t think the latter is available to new users in the US any more). Either should give you a LNURL address which you can add to your nostr client. There are alternatives (running your own lightning node, and self-custody wallets like nostr:npub1mutnyacc9uc4t5mmxvpprwsauj5p2qxq95v4a9j0jxl8wnkfvuyque23vg etc) but I am not very technical and these require that you allocate quite a lot of sats in order to open lightning channels. Hopefully others here can also help you and offer other suggestions too #askNostr
