Web3 & Blockchain: How They Impact Front-End Development

Web3 and blockchain technologies are reshaping how we build and interact with web applications. While much of the attention goes to backend protocols and decentralized finance (DeFi), front-end developers are increasingly being brought into the spotlight to bridge traditional UX expectations with decentralized logic. What is Web3? Web3 refers to the next evolution of the internet—decentralized, user-controlled, and built on blockchain. Unlike Web2, where centralized servers own your data, Web3 allows users to own, control, and monetize their data using decentralized applications (dApps). Blockchain: The Foundation Blockchains are distributed ledgers that power cryptocurrencies like Ethereum and Bitcoin. However, for front-end developers, their primary relevance lies in interacting with: Smart Contracts (on Ethereum, Polygon, etc.) Wallets (like MetaMask, WalletConnect) dApps (decentralized applications) How Blockchain Impacts Front-End Development New UI/UX Challenges Smart Contrac...
