NFT 10K LIST

Posted by Mike Gover

Required skills

List a 10k NFTs collection on opensea without paying gas fee using a smart contract.
My intentions are:
• deploy a new smart contract on Ethereum ( not paying gas fee, just like uploading one by one from opensea (lazy mint)).
• then, see all my 10k nfts on opensea without minting.
• after that edit my contract and see the changes in opensea.
Why?
Because I need the possibility to change some description, price and image after seeing all images on opensea.
Is that possible?
