Hey guys, I was wondering, is it possible to store metadata of ERC-721 on-chain without connecting JSON url? And is it possible to call minting function with specific data?
E.g. I want to represent a car with ERC-721 token, so each user can create a new car and it would have a model, colour etc.
Or should I still provide metadata with json on frontend?

sure, the metadata can be on-chain fully. just costs a lot more.
