I haven't tried this boltz exchange thing or whatever, maybe that would be useful if you do this regularly. I sort of don't mind for convenience and because I rarely do it. Maybe. I'll see how I feel at home lol
Also apparently this Aqua wallet is useful to send on-chain. Not tried it myself tho.
Just in case you also haven't heard of it.
They don't have a lnurl tho
