Late night weekend ship, verify ownership in an ERC721 NFT collection. 

First of many new credential types.

Nice! Farcaster IDs are not 721s, but they are pretty close. What's necessary to prove ownership of an FID < n ?

Is it easy enough I could try to add it myself?

I'm eth newbie..just learning

Not as straightforward because current circuit is doing a storage validation based on ecrecover of signed message from wallet that has the token. UX wouldn’t be ideal since most people don’t interact with their custody address.

I’m working on a new circuit that will let you just prove FID based on SIWF and then can use that to validate < N fid or >X followers

Gotcha, maybe I can try Yoink score, then. I think that should work with the same model.

Yeah if the data is onchain, you can fork the existing circuit and simply just change the assertion that’s happening, the rest of the circuit should just be the same since it’s just doing a storage proof validation
