Hands-on DApp Design and Development Using Web3 Tools

Go from DApp architecture to a deployed application: set up Truffle and Hardhat, connect a React frontend to smart contracts with Web3.js and Ethers.js, test on testnets, then add Redux state, IPFS off-chain data and the security that keeps your DApp safe.

Hands-on DApp Design and Development Using Web3 Tools teaches the complete process of designing, developing and deploying decentralized applications on blockchain networks - from their unique architecture to integrating smart contracts.

You start with what makes DApps different and the essential tools - Truffle, Hardhat, Web3.js and Ethers.js - then design user interfaces, connect your frontend to the blockchain, and build applications that interact with smart contracts. Advanced modules cover Redux state management, IPFS off-chain data and robust DApp security.

It's course 2 of Board Infinity's Blockchain Technology Applied specialization on Coursera, built for aspiring developers ready to work in decentralized technology.

03 What you'll build

Four things you'll build. Real contracts, real testnets.

This is a hands-on course - every module ends with something running, not just concepts you watched.

Module 1

Module 2

A React DApp interface

A user-friendly frontend designed with DApp UI/UX principles and wired to Web3.

A DApp deployed to a testnet

Smart contracts connected, transactions managed, data read and written - then deployed with CI/CD.

Module 3

A hardened, scalable DApp

Redux state management, IPFS off-chain data, and security audits and monitoring in place.

05 Tools & skills

Master the stack that powers decentralized apps.

The tools you work in, and the skills you leave with.

Dev frameworks

Truffle & Hardhat

The environments where you compile, test and deploy the contracts behind your DApp.

Blockchain libraries

Web3.js & Ethers.js

The libraries that let your frontend read the chain, send transactions and call contracts.

Frontend

React & Redux

The interface your users see, and the state management that keeps it in sync with the chain.

Off-chain storage

IPFS

Decentralized storage for the data that's too large or too costly to keep on-chain.

Skills you leave with

Interfaces people can use without knowing it's a blockchain.

  • Application design
  • User interface (UI) design
  • User experience design
  • UI/UX design

Development

Wiring a frontend to contracts on a live network.

  • Blockchain
  • Front-end web development
  • React Redux
