Build a Dapp with ViteJS, React and MetaMask SDK

·

Creating a decentralized application (dapp) has never been more accessible, especially with modern development tools like ViteJS, React, and the MetaMask SDK. In this comprehensive guide, you'll learn how to build a full-stack dapp that generates on-chain SVG NFT tickets — a perfect use case for event platforms, digital collectibles, or gamified experiences.

By the end of this tutorial, you’ll understand how to integrate wallet connectivity, interact with smart contracts, and deploy your dapp to Linea, a Layer 2 zkEVM network by Consensys. Whether you're a beginner exploring Web3 development or an experienced developer looking to streamline onboarding, this walkthrough delivers practical insights.

Why Use ViteJS and React for Web3 Development?

ViteJS is a next-generation frontend tooling that offers lightning-fast development server startup and hot module replacement. Paired with React — the most widely used JavaScript library for building user interfaces — it creates a powerful foundation for scalable dapps.

The combination ensures:

This stack is ideal for developers who want fast iteration without sacrificing performance.

Integrating the MetaMask SDK

One of the biggest hurdles in Web3 adoption is user onboarding. The MetaMask SDK simplifies this by enabling seamless connection between your dapp and users’ MetaMask wallets — whether they’re using the browser extension or mobile app.

How It Works

The SDK abstracts away complex blockchain interactions. With just a few lines of code, you can:

import { MetaMaskSDK } from '@metamask/sdk';

const MMSDK = new MetaMaskSDK();
const provider = MMSDK.getProvider();

// Trigger connection
await provider.request({ method: 'eth_requestAccounts' });

This integration removes friction for non-crypto-native users and enhances conversion rates across devices.

What Is Linea? A Brief Overview

Linea is a privacy-preserving, EVM-equivalent Layer 2 rollup built by Consensys. As a zkEVM network, it uses zero-knowledge proofs to validate transactions off-chain while maintaining Ethereum-level security.

Key Benefits of Linea:

Deploying your dapp on Linea allows you to scale efficiently without compromising decentralization or developer experience.

Step-by-Step: Building Your On-Chain SVG NFT Dapp

Let’s walk through the core stages of building and deploying your dapp.

1. Set Up the Project

Start by cloning the official GitHub repository provided in the tutorial starter kit:

git clone https://github.com/MetaMask/example-dapp-template.git
cd example-dapp-template
npm install

Then launch the dev server:

npm run dev

You now have a working React + Vite environment connected to MetaMask.

2. Configure MetaMask SDK

Install the SDK:

npm install @metamask/sdk

Initialize it in your main app component or a dedicated Web3 service file. Make sure to configure it with your preferred Infura or Alchemy RPC endpoints for optimal connectivity.

3. Create the SVG NFT Smart Contract

Your contract will generate unique SVG-based NFTs stored directly on-chain (no IPFS required). This increases permanence and censorship resistance.

Use Solidity with OpenZeppelin’s ERC721 standard:

pragma solidity ^0.8.0;

import "@openzeppelin/contracts/token/ERC721/ERC721.sol";

contract SVGTicket is ERC721 {
    uint256 public tokenId;
    
    constructor() ERC721("SVGTicket", "TIX") {}

    function mintTicket() external {
        _safeMint(msg.sender, tokenId);
        tokenId++;
    }

    function _baseURI() internal pure override returns (string memory) {
        return "data:image/svg+xml;base64,";
    }
}

Compile and deploy this contract using Hardhat or Foundry to Linea’s testnet first.

Deploying to Linea

Once your smart contract is tested locally, deploy it to Linea Goerli testnet:

  1. Obtain test ETH from the Linea faucet
  2. Configure your network settings in hardhat.config.js
  3. Run deployment script targeting Linea’s RPC endpoint

After successful deployment, update your frontend to point to the deployed contract address and ABI.

Frequently Asked Questions (FAQ)

Q: Do I need prior blockchain experience to follow this tutorial?
A: While helpful, it’s not required. Basic knowledge of JavaScript and React is sufficient to get started. The MetaMask SDK handles much of the complexity behind the scenes.

Q: Can I use this dapp structure for other NFT projects?
A: Absolutely. The architecture is modular — swap out the SVG logic for dynamic metadata, animations, or generative art algorithms.

Q: Is Linea suitable for production dapps?
A: Yes. Linea’s mainnet is live and supports real-world applications with low fees and high scalability.

Q: Are SVG NFTs stored entirely on-chain?
A: Yes. Unlike many NFTs that rely on external storage (like IPFS), SVG content can be encoded directly into the token URI using base64, ensuring full on-chain persistence.

Q: How does the MetaMask SDK improve user onboarding?
A: It enables one-click wallet setup for new users, even if they don’t have MetaMask installed — reducing drop-off during onboarding.

Final Thoughts

Building a functional dapp with ViteJS, React, and the MetaMask SDK is now within reach of any modern web developer. By leveraging Linea as your deployment target, you gain scalability and cost-efficiency without sacrificing Ethereum’s security model.

This stack exemplifies the future of Web3: fast, user-friendly, and developer-centric.

Whether you're creating digital tickets, collectibles, or interactive experiences, the tools are here — all that's left is to build.
