Free, code-first Solidity guide - 13 chapters from fundamentals to DeFi, security, gas optimization, and production testing with Foundry.
A Comprehensive Engineering Guide to Smart Contract Auditing, EVM Internals, DeFi Exploitation, Protocol Economics, and Blockchain SecuritySmart contracts operate in environments where code, financial assets, cryptographic authorization, and economic incentives interact directly. A subtle implementation error can compromise access controls, corrupt accounting, undermine protocol solvency, or expose digital assets to irreversible loss. Understanding these risks requires more than familiarity with Solidity syntax. It demands a rigorous examination of execution semantics, storage architecture, transaction ordering, protocol mathematics, and the assumptions that connect individual contracts to larger decentralized systems.Smart Contract Security: Finding DeFi Vulnerabilities is a comprehensive, implementation-focused engineering reference to identifying, analyzing, testing, and mitigating vulnerabilities in Ethereum smart contracts and decentralized finance protocols. Across 40 chapters, it progresses from EVM architecture and Solidity execution to advanced DeFi attack surfaces, automated security analysis, formal verification, real-world exploit investigations, and professional auditing practices.
The Solana MEV Playbook: Building High-Frequency Arbitrage and MEV Bots in Rust Solana moves in milliseconds. MEV moves in microseconds. If your bot is slow, someone else eats your trade. This is the technical playbook for engineers who want to build production-grade MEV and arbitrage infrastructure on Solana — in Rust, from the ground up, with real code and real architecture.
Build real smart contracts with confidence from your very first line of Solidity. This hands-on guide walks you from blockchain fundamentals to advanced security, DeFi, NFTs, DAOs and production-ready development. Packed with practical examples and proven patterns, it gives you the skills to create secure Ethereum applications that are ready for the real world.
