It will be deployed on Matic Network (but should be similar and work on Eth net too) 3. Now I can mint one NFT, but I want to mint/create "N" # of NFTs. Probably this means we have a JSON config for our project, and then scan a directory and mint an NFT for each file in the directory. 4. Integrate with OpenSea.
