I decided to go with a GPU version, I had problems with tor-v3-vanity, but nano-vanity created my custom tor v3 address with a seed. However, I don't know how the heck to implement this into torrc, and the hidden directory. I don't have a hs_ed25519_public and secret key, only a SEED number and tor address that I created a prefix.
I think mkp224o may create those files, but it runs parallel on CPU and can take days. That's okay, I guess. I just wanted to speed things up, and I was able to generate my custom address, but I don't know how to proceed.
