Non-fungible tokens (NFTs) are unique digital tokens on the blockchain that can represent distinct items such as digital art, game assets, or rare collectibles. Unlike fungible tokens, each NFT is one-of-a-kind, and ownership concerns the specific item rather than quantity. This tutorial guides users through creating NFT artwork and deploying it on the OpenSea marketplace, utilizing Chainlink's Verifiable Random Function (VRF) to generate unique emoji and background color combinations for each NFT. The process involves cloning a Chainlink smart contract repository, setting up necessary environment variables, and using Solidity to develop an NFT smart contract that incorporates random emoji and color generation into the NFT's on-chain metadata stored in Scalable Vector Graphics (SVG) format. After deploying the contract on the Ethereum Rinkeby test network, developers can mint NFTs and view them on OpenSea. The tutorial also highlights using the latest Chainlink VRF v2 for improved random value requests and subscription management.
