Create a NFT

The following sample will show you how to create a NFT on Hedera Hashgraph. We will first generate a request for the end user. Once validated, you will get notified for the NFT's creation success.‌

Prerequisites:

Getting started

Step 1: Import the following modules

Let's continue building on the index.js from the previous example (Environment Set-up) and add the following modules:

const { Client, CategoryNFT } = require("@xact-wallet-sdk/client");
require("dotenv").config();

Step 2: Get Xact Fees

In order to get the fees from our service, you need to proceed as below :

const xactFees = await client.getXactFeesCreateNFT();

Step 3: Initializing Create NFT

When initializing a NFT's creation, a request will be sent to the end user

/* Update the fields with your informations */
const name = 'NFT Test';
const description = 'Description of my NFT';
const category = CategoryNFT.ART;
const creator = 'Johny.B';
const cid = ''; /* cid linked to the NFT - IPFS storage */
const supply = 1; /* Nb of NFT available */
const fromAccountId= ''; /* Account ID of the user */
const customRoyaltyFee = {
        numerator: 1,
        denominator: 10,
        fallbackFee: 100, /* in Hbar */
};/* Optional*/

await client.createNFT({fromAccountId, name, description, category, creator, cid, supply, customRoyaltyFee});

Step 4: Listen for the NFT's creation

Finally get notified when your NFT has been successfully created !

/* Subscribe to new Create NFT Validation */
client.createNFTValidation().subscribe(nft => {
    console.log('NFT Created', nft);
});

Code Check ✅

Your index.js file should look like this:

const { Client, CategoryNFT } = require("@xact-wallet-sdk/client");
require("dotenv").config();

async function createNFT() {

    //Grab your api key from your .env file
    const apiKey = process.env.API_KEY;


    // If we weren't able to grab it, we should throw a new error
    if (apiKey == null) {
        throw new Error("Environment variables API_KEY must be present");
    }
    /* Create a new instance of Client */
    const client = new Client({apiKey});
    
    /* Init the connexion */
    await client.initConnexion();
    
    /* Update the fields with your informations */
    const name = 'NFT Test';
    const description = 'Description of my NFT';
    const category = CategoryNFT.ART;
    const creator = 'Johny.B';
    const media = ''; /* base64 format */
    const supply = 1; /* Nb of NFT available */
    const fromAccountId= ''; /* Account ID of the user */
    
    /* Request for NFT's creation */
    await client.createNFT({fromAccountId, name, description, category, creator, media, supply});
    
    /* Listen for Creation's success */
    client.createNFTValidation().subscribe(nft => {
        console.log('NFT Created', nft);
    });
}

createNFT();
