Learn how to build a complete NFT event ticketing platform using the Conflux blockchain!

#1

NFTs are revolutionizing industries beyond digital art and collectibles, and event ticketing is no exception. By leveraging blockchain technology, we can create secure, transparent, and efficient platforms for managing event tickets as NFTs. In this blog, we’ll walk you through building a complete NFT event ticketing platform using the Conflux blockchain. Conflux offers high scalability, low fees, and energy efficiency, making it an excellent choice for this use case.

By the end of this guide, you’ll have a fully functional platform where users can mint, list, and manage event tickets as NFTs. Let’s get started!

What You’ll Learn

  1. How to develop a smart contract tailored for NFT-based event ticketing.

  2. Deploying and verifying the smart contract on the Conflux eSpace Testnet using Hardhat.

  3. Building an interactive React.js frontend for minting and managing NFTs.

  4. Using IPFS for metadata storage to ensure decentralization.

Step 1: Develop the Smart Contract

The first step is to create a smart contract that adheres to the ERC-721 standard, customized for event ticketing. Each NFT will represent a unique ticket with metadata containing event details such as event name, seat number, and price.

Here’s a high-level breakdown of the smart contract:

  1. ERC-721 Standard: Ensures each ticket is unique and transferable.

  2. Metadata Storage: Uses the ERC721URIStorage extension to associate NFTs with metadata stored on IPFS.

  3. Marketplace Features: Allows users to mint, list, and sell tickets on the blockchain.

Key Features of the Smart Contract

  1. createToken: Mints a new NFT and assigns metadata to it.

  2. createMarketItem: Lists the NFT for sale by transferring ownership to the contract.

  3. createMarketSale: Facilitates the sale of the NFT, transferring ownership to the buyer.

Step 2: Deploy the Smart Contract

To deploy the contract on the Conflux eSpace Testnet, we’ll use Hardhat. Follow these steps:

  1. Hardhat Setup: Install and configure Hardhat in your project.

  2. Deployment Script: Write a script to deploy the contract and log its address.

  3. Hardhat Config File: Configure the network settings for Conflux eSpace Testnet.

Deployment Script

const { ethers } = require("hardhat");

async function main() {
  const NFTMarketplace = await ethers.getContractFactory("NFTMarketplace");
  const nftMarketplace = await NFTMarketplace.deploy();
  await nftMarketplace.deployed();

  console.log("NFT Marketplace deployed to:", nftMarketplace.address);
}

main().catch((error) => {
  console.error(error);
  process.exitCode = 1;
});

Step 3: Build the Frontend

Next, we’ll create a user-friendly interface using React.js. The frontend will allow users to mint NFTs, view their tickets, and list them for sale

Minting Form Component

This component collects event details and uploads the metadata to IPFS using Lighthouse:

async function createMarket() {
  const metadata = {
    name: eventName,
    description: eventDescription,
    image: imageUrl,
    price: ethers.utils.parseUnits(price, "ether")
  };

  const ipfsUrl = await uploadToIPFS(metadata); // Upload metadata
  await contract.createToken(ipfsUrl, price);  // Mint NFT
}

Creator Dashboard

The dashboard fetches listed NFTs and displays them in a grid:

async function loadNFTs() {
  const data = await contract.fetchItemsListed();
  const items = await Promise.all(data.map(async (i) => {
    const metadata = await axios.get(i.tokenURI);
    return {
      ...metadata.data,
      price: ethers.utils.formatUnits(i.price, "ether"),
    };
  }));

  setNfts(items);
}

Step 4: Store Metadata with IPFS

IPFS is a decentralized storage solution perfect for hosting metadata and images for NFTs. Tools like Lighthouse or Pinata simplify the process.

  1. Upload Metadata: Package event details into a JSON file and upload it to IPFS.

  2. Generate URI: Use the returned IPFS hash as the metadata URI in the smart contract.

Conclusion

Congratulations! You’ve successfully built an NFT event ticketing platform on the Conflux blockchain. This platform ensures security, transparency, and ease of use for managing event tickets. By leveraging Conflux’s efficiency and NFT capabilities, you’ve created a scalable solution for the future of event management.
