Web3 development differs significantly from traditional web development. Learn the fundamentals, tools, and best practices for building decentralized applications.
Core Concepts
- Wallets and key management
- Smart contract programming (Solidity, Rust)
- Gas costs and optimization
- Security and auditing
- Decentralized storage (IPFS, Arweave)
- Indexing and querying (The Graph)
Development Stack
Smart Contracts: Solidity on Ethereum, Rust on Solana
Frontend: React/Vue with Web3.js or Ethers.js
Backend: Traditional servers or fully decentralized
Deployment: Mainnet, testnets, Layer 2
Learning Path
- Learn Solidity basics
- Deploy to testnet
- Build simple dApp
- Get smart contract audited
- Deploy to mainnet
