I’m currently syncing the standard openzeppelin Transfer(address,address,uint256) event when minting an NFT, and saving the data in an object called NFT (I’m also using a filter so the object only gets saved when the “from” address is 0x0). That way, I have a table where I can see all the NFTs that have been minted in my app.
However, I would like to save an extra column in that object (the NFT series to which that NFT belongs, I’m trying to implement series purely on the frontend, there is only one smart contract), but the data in it is never seen by the smart contract, only by the frontend.
How can I do this? Thanks in advance
