Creating a dataNFT

This tutorial guides you through the process of creating your own data NFT using Ocean libraries. To know more about data NFT please refer this page.

Prerequisites

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);
  });

{% endcode %}

Executing script

node create_dataNFT.js

{% endtab %}

{% tab title="ocean.py" %} {% code title="create_dataNFT.py" %}

# Note: Ensure that .env and config.py are correctly setup
from config import web3_wallet, ocean

data_nft = ocean.create_data_nft(
    name="NFTToken1",
    symbol="NFT1",
    from_wallet=web3_wallet,
    # Optional parameters
    token_uri="https://example.com",
    template_index=1,
    transferable=True,
    owner=web3_wallet.address,
)
print(f"Created dataNFT. Its address is {data_nft.address}")
