@snow_nft I always put it in the traits section of the metadata but I don't think it is enough.
Should have a function on the contract to access it. It would be nice if the price history was tracked in the contract also.
@snow_nft If we add to the 721 spec or create our own contract we could add it to a function on the contract. Or maybe we should be putting all metadata into a base64 in the tokenUri instead.
If we want to track it better it should be a function,
