  • Copy CID and change mintNFT("ipfs://your CID")" in mint-nft.js

Deployment

• Create .env like this :

  API_URL = "alchemy api https url"
  PRIVATE_KEY = "metamask private key"
  PUBLIC_KEY = "metamask public key"

• Deploy the smart contract npx hardhat --network goerli run scripts/deploy.js

  • Go to the Goerli etherscan for check.
