How to use

Before starting, please create an account on NFT Storage in order to store all the required metadata files. Here is the solution diagram:

1. Run ganache-cli -i 2022 to execute a local blockchain. Don't forget to import some private keys to MetaMask;

2. In solidity/ directory, run truffle migrate in order to deploy the NFT smart contract in the blockchain;

3. Move build/contracts/NFT.json into web/src/contracts/ directory;

4. In web/ directory, run npm install then npm start to execute the web server;

You are now able to use the web site and upload image. Resulting metadatas will be stored in nft.storage and its URI in the local blockchain.

In order to display all NFTs, web site calls all token ids stored in the blockchain in order to load all metadata and, hence, all image URL.
