Do you know how to do it? It's a bit beyond me, I just use custodial lightning wallet, which is not ideal obviously. (You can send send to an on-chain non-custodial cold storage wallet fairly easily once in a while, as needed tho obviously).

I'm sure someone with a bit more knowledge can help set you up if you need it. Just use the asknostr hashtag if you need help.

Or you can ask me but I'll probably try to refer you to someone actually helpful lol
