For someone who understands ZKPs: is there an easy way to make the EdDSA signatures compatible with ZK stuff for /frames?

It really depends what you’re trying to do.

Verifying an eddsa signature in zk isn’t the hard part. Do you also have to verify the key is a valid signer for some fid? What about fid replay protection?

It becomes easier if a trusted party would index fid and signers in some verifiable structure that’s zk friendly.

Then it’s just a membership proof + eddsa verification. 

Otherwise, you need a zkEVM or state proof verification, which has an insane overhead. Can’t be done client side.
