• Node.js
• yarn pkg manager
• Alchemy account (to connect to the blockchain.)

• yarn install
• copy and save .env file

To run hardhard

• locally: hh:local
• ropsten: hh:ropsten

Please replace hh commands below with the right command depending on the network you wish to work with.

IMPORTANT Please check hardhat.config.js when you deploy somewhere else than local.

You don't have to this as the contract is already deployed to ropsten. https://ropsten.etherscan.io/address/0xA9317568b8917076575B55A16B7669b94b8F29ff

You can deploy this to your local node

• Make sure your local node is running with yarn node
• Compile the .sol files with yarn compile. This will create an "artifacts" folder which is needed to deploy and later run functions
• Call the scripts/deploy.js script with hardhat. yarn hh scripts/deploy.js

• yarn hh scripts/min-nft.js

• yarn hh scripts/get-owner.js

• the blockchain only stores the owner of the NFT and the location of the meta data URI.
• the token metadata called as tokenURI is a json file which is stored off chain.
• IPFS filesystem is the upcoming choice for the storage of the meta data json.
