Web3 is not another overhyped buzzword—it is the future of the internet. While Web2 is dominated by large centralized services, Web3 specifies the advent of decentralized applications, blockchains, and giving users ownership of their data.
This beginner’s guide will guide developers who would like to get involved with Web3 capabilities in 2025.
🌐 What Is Web3?
- Web3 (or Web 3.0) refers to the third-generation of the internet based on decentralization and decentralized technologies including:
- Blockchain
- Cryptocurrencies
- Smart Contracts
- NFTs (Non-Fungible Tokens)
- Decentralized Finance (DeFi)
- DAOs (Decentralized Autonomous Organizations)
- Web3 removes the need for a middleman and enables users to have complete ownership of their digital identity and digital assets.
🧰 Skills You Need to Get Started with Web3 Development
You do not need to be an expert on blockchains to get started, as the skills mentioned below are recommended:
- Basic Web Development (HTML, CSS, JavaScript)
- JavaScript Frameworks (React or Vue.js)
- Blockchain Essentials (Understanding Ethereum, Bitcoin)
- Solidity (programming language for writing Ethereum smart contracts)
- Version Control (Git + GitHub)
🛠 Tools and Technologies You Will Use
Here is a stack of tools in use by Web3 developers in 2025:
- Tool / Platform Purpose
- Solidity Writing smart contracts for Ethereum
- Hardhat / Truffle Developing and deploying smart contracts
MetaMask – A browser wallet to interact with the blockchain. Ethers.js / Web3.js – JavaScript libraries for interacting with smart contracts. IPFS – Decentrualized file storage. Alchemy / Infura – Blockchain APIs & infrastructure.

👨💻 First Steps: Your Web3 developer roadmap.
- Understand the basics of blockchain technology – Understand how decentralized networks and smart contracts work.
- MetaMask – Setup – Install MetaMask and connect it to the Ethereum testers.
- Writing your First Smart Contract – Solidity – Look at a simple “Hello World” contract built using Hardhat.
- Deploy it on a test net – Deploy your smart contract on either the Goerli test net or Sepolia test net.
- Build a dApp (Decentralized App) – Use React and the Ethers.js library to create a frontend that interacts with your contract.
