Is there a good open source cashu lightning address sever
Discussion
Check out https://github.com/cashubtc/npubcash-server
Make sure to look at the v2 branch that does not require an external Lightning backend (it uses the mints)
TBH the documentation is lacking. I’ll make sure to update it over the weekend and ping you. I’d love to see it hosted in the wild
v2 is currently live as npubx.cash and integrated in Cashu.me
