Creating a dataNFT

This tutorial will guide you for creating your own data NFT using Ocean libraries. To know more about data NFT please refer this page.

Configuration

See this guide on defining a .env file and a configuration file.

Create a script to deploy dataNFT

Create a new file in the same working directory where configuration file (config.py/config.js) and .env files are present, and copy the code as listed below.

{% tabs %} {% tab title="ocean.js" %} {% code title="create_dataNFT.js" %}

// Import dependencies
const { NftFactory } = require('@oceanprotocol/lib');
const Web3 = require('web3');

// Note: Make sure .env file and config.js are created and setup correctly
const { web3Provider, oceanConfig } = require('./config');

const web3 = new Web3(web3Provider);

// Deinfe a function which will create a dataNFT using Ocean.js library
const createDataNFT = async () => {

  // Create a NFTFactory
  const Factory = new NftFactory(oceanConfig.erc721FactoryAddress, web3);

  const accounts = await web3.eth.getAccounts();
  const publisherAccount = accounts[0];

  // Define dataNFT parameters
  const nftParams = {
    name: '72120Bundle',
    symbol: '72Bundle',
    // Optional parameters
    templateIndex: 1,
    tokenURI: 'https://example.com',
    transferable: true,
    owner: publisherAccount
  };

  // Call a Factory.createNFT(...) which will create a new dataNFT
  const erc721Address = await Factory.createNFT(
    publisherAccount,
    nftParams
  );

  return {
    erc721Address
  };
};

// Call the create createDataNFT() function
createDataNFT()
  .then(({ erc721Address }) => {
    console.log(`DataNft address ${erc721Address}`);
    process.exit();
  })
  .catch((err) => {
    console.error(err);
    process.exit(1);
  });
