NFT mint functionality, where _mint operation uses Verifiable Random Function (VRF) from Chainlink. Note that this application use Vertion2.

How does Chainlink VRF Version2 work?

• Deploy your smart contract
• Create subscription
• Fund your subscription. In the example, I funded with 2 LINK.
• Add a consumer of your subscription, which is the address of the contract you deployed.
• Request randomness, wait for the fallback call.
• fallback call triggers _mint operation.

How to run?

This version is configured to run on Rinkeby test net. Assuming you have .env file with the private key of your account:
