Weeks ago, I have set up my own ln node (Umbrel). Now I try to use the lightning network for receiving donations. Here start my questions.
- How can I set up a donation address where donors can decide how much to donate? (I have discovered "keysend" as a possibility. Unfortunately, it is not widely used among users. Isn't it?)
- How can I create an invoice for open-ended deposits?
Please take for your answers into account, I'm an UX designer without serious developer skills.
