Web3 (2 posts)

Web3 focuses on decentralized applications that leverage smart contracts and public blockchains for transparency and composability. Expect practical guides on Solidity patterns, contract testing with Foundry/Hardhat, and frontend integration using Wagmi/Viem or Ethers.js. We explore wallet UX (MetaMask, Rainbow, WalletConnect), account abstraction (ERC-4337), and L2 rollups for cheaper, faster transactions. You’ll also find patterns for NFTs, DeFi, governance, subgraphs/indexing, data oracles, and decentralized storage (IPFS/Arweave), plus security reviews and deployment playbooks for multi-chain environments (Ethereum, Polygon, Base, Arbitrum, Optimism).
