I’m a newbie here, sorry if my question is too dumb.
I was following this tutorial to bulk upload NFT art in Opensea.
I was able to upload a collection of Images on testnet, but when I copy the contract on mainnnet, it is asking me to pay gas fee.
Polygon doesn’t have any gas fee when I manually upload NFTs in Opensea.
What’s the difference here or what am I missing?
