How To Build an App NFT

Using Pinata, Polygon, and OpenSea

Getting Started

Creating The Contract

mkdir nft-app-contract && cd nft-app-contract
npm init
npm install --save-dev hardhat
npx hardhat
npm install @openzeppelin/contracts
npx hardhat test

The Application

npx create-react-app app-nft-frontend
"homepage": "./"
npm i -g pinata-upload-cli
pinata-cli -a JWT_HERE
"deploy": "npm run build && sh ./"
pinata-cli -u ./build
npm run deploy

Making an App NFT

require("@nomicfoundation/hardhat-toolbox");module.exports = {
solidity: "0.8.9",
module.exports = {
solidity: "0.8.9",
networks: {
mumbai: {
url: ``,
"name": "App NFT",
"description": "A full application, accessible as an NFT, sold as an NFT, and transferred as an NFT",
"animation_url": "ipfs://HASH_FROM_APP_BUILD"
pinata-cli -u ./metadata.json
const hre = require("hardhat");
const URI = "ipfs://METADATA_CID"
async function main() {
const AppNFT = await ethers.getContractFactory("AppNFT");
const appNft = await AppNFT.deploy(URI);
await appNft.deployed(); console.log(`Contract deployed to ${appNft.address}`);
main().catch((error) => {
process.exitCode = 1;
npx hardhat run scripts/deploy.js
Contract deployed to 0x5FbDB2315678afecq367f032d93F642f64170aa3
npx hardhat run scripts/deploy.js --network mumbai
