Running this project

Gitpod

To deploy this project to Gitpod, follow these steps:

  1. Click this link to deploy

Open in Gitpod

  1. 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.

MetaMask RPC Import

Local setup

To run this project locally, follow these steps.

  1. 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
  1. Start the local Hardhat node
npx hardhat node
  1. With the network running, deploy the contracts to the local network in a separate terminal window
npx hardhat run scripts/deploy.js --network localhost
  1. 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.
