Most developers can write Smart Contracts.
Very few can build a real DApp.

In today’s powerful session, we build a complete decentralized application from scratch using Next.js, Hardhat, MetaMask, and Ethers — and prove everything live with real transaction confirmations.

This is not theory. This is the full Web3 development workflow professionals use.

What We Built in This Video
What a DApp really is
Creating a Next.js app
Installing ethers package
Setting up blockchain folder inside Next.js
Initializing Hardhat project
Running local blockchain using npx hardhat node
Creating Hardhat Local network inside MetaMask
Setting Chain ID, RPC URL & Currency Symbol
Importing private key from Hardhat into MetaMask
Getting 10,000 free local ETH
Deploying contract using Hardhat Ignition
Getting deployed contract address
Integrating ABI + contract address into frontend
Connecting wallet from Next.js
Triggering transactions from frontend
MetaMask popup + successful confirmation proof

This is how real DApps are built before going to testnet or mainnet.

This tutorial is part of Phase 3 of our Blockchain → Solidity → Web3 Roadmap only on The Techzeen.

If you want to become a real Web3 developer in 2026, this workflow is mandatory.
