goodnight.
I created a smart contract on red epolygon through opensea, but I don't know how to play my nfts on this contract.
I researched a little and understood the pinata concept, and I would also like to know how and where I put the generated pinata code in my nfts that I will upload.
I would like to know how to upload an entire collection automatically, pulling the individual data of each item. thanks.
