Those pieces I want to be able to be digitally authenticated and for the holder to be able to link that nft to their own personal information (shipping address, name) on a secure page. If an NFT owner decides to sell their NFT after linking it with their personal information, I want there to be a way for the system to notice that the NFT has sold and that users' personal information is erased. This page will be able to create a nice and simple spreadsheet of all nft holders and their info (if they have decided to NOT link it to their personal information then on the spreadsheet it will just be blank), this spreadsheet is just for me to see, and be ...

    We are working with an artist that created an animation set to display in six different TV's all around Mexico. We want to make that animation an NFT so the collector that buys the TV also owns the digital art (ex 1/6). Additionally we want that in the smart contract (if the owner of the TV ever chooses to sell his digital art) a small percentage of the sale goes to the artist. Since most of our clients are not familiar with the NFT workspace we were thinking of saving the NFT in a hard wallet so when they buy the TV they also get a the wallet that has the NFT on it.

    Hi there! I'm looking to create a new map based NFT website that allows people to mint / resell new NFTs directly on the site. Probably looking to do it on the polygon network as the NFT's will be low cost so need low gas fees, and to build he site I think React (or similar). I'm looking to start a simple website out to get proof of concept up and running, and then after launching that will be keen to continue to work on the website ongoing with you. Feel free to put a place holder bid if you are interested and I can send you more information about it and we can discuss. Thanks! Mike
