just simple like wss://auth.nostr1.com/
only store gift wrap events and require auth
so give me your required spec.
like: which kinds you want accept? what features do you need? do you want blossom or nip-86? which methods?
then ill develop one for you. :salute:
fyi: https://github.com/dezh-tech/alienos is also a lightweight relay which don't need any extra services and its 100% manageable using nip86!
Discussion
ok. ill develop it in next few days. ill try to add any feature that may be useful.
