Full stack NFT marketplace built with Polygon, Solidity, IPFS, & Next.js

This is the codebase to go along with tbe blog post Building a Full Stack NFT Marketplace on Ethereum with Polygon

Running this project

Gitpod

To deploy this project to Gitpod, follow these steps:

Click this link to deploy

Import the RPC address given to you by GitPod into your MetaMask wallet

This endpoint will look something like this:

https://8545-copper-swordtail-j1mvhxv3.ws-eu18.gitpod.io/

The chain ID should be 1337. If you have a localhost rpc set up, you may need to overwrite it.

Local setup

To run this project locally, follow these steps.

Clone the project locally, change into the directory, and install the dependencies:

git clone https://github.com/dabit3/polygon-ethereum-nextjs-marketplace.git

cd polygon-ethereum-nextjs-marketplace

# install using NPM or Yarn
npm install

# or

yarn

Start the local Hardhat node

npx hardhat node

With the network running, deploy the contracts to the local network in a separate terminal window

npx hardhat run scripts/deploy.js --network localhost

Start the app

npm run dev

Configuration

To deploy to Polygon test or main networks, update the configurations located in hardhat.config.js to use a private key and, optionally, deploy to a private RPC like Infura.

require("@nomiclabs/hardhat-waffle");
const fs = require('fs');
const privateKey = fs.readFileSync(".secret").toString().trim() || "01234567890123456789";

// infuraId is optional if you are using Infura RPC
const infuraId = fs.readFileSync(".infuraid").toString().trim() || "";

module.exports = {
  defaultNetwork: "hardhat",
  networks: {
    hardhat: {
      chainId: 1337
    },
    mumbai: {
      // Infura
      // url: `https://polygon-mumbai.infura.io/v3/${infuraId}`
      url: "https://rpc-mumbai.matic.today",
      accounts: [privateKey]
    },
    matic: {
      // Infura
      // url: `https://polygon-mainnet.infura.io/v3/${infuraId}`,
      url: "https://rpc-mainnet.maticvigil.com",
      accounts: [privateKey]
    }
  },
  solidity: {
    version: "0.8.4",
    settings: {
      optimizer: {
        enabled: true,
        runs: 200
      }
    }
  }
};

If using Infura, update .infuraid with your Infura project ID.
