Solidity Smart Contracts: From Zero to Production is a free, code-first guide to building smart contracts with Solidity and Foundry. Written for developers who know programming but are new to Web3, this book covers everything from your first contract to production deployment, real-world security, and gas optimization.



What's inside:


- Solidity fundamentals — types, storage, functions, events, custom errors


- Design patterns — Ownable, Pausable, ReentrancyGuard, Proxy/UUPS


- Token standards — ERC-20, ERC-721, ERC-1155 from the interface up


- DeFi development — AMMs, Chainlink oracles, lending mechanics


- Security with real exploits (DAO, Mango Markets)


- Gas optimization — storage packing, immutable, unchecked blocks


- Foundry toolchain — fuzz testing, invariant testing, fork testing


- Complete MultiSig Wallet project with tests


- Smart contract auditing process


- Advanced topics — ERC-4337, EIP-7702, ERC-8004, x402
