Book synopsis

What If Your Protocol's Security Isn't Broken by Code - But by the EVM Itself?

Every month, millions vanish from smart contract protocols. Not because developers are careless, but because the technical attack surface is vast, evolving, and poorly understood. Storage slot collisions silently corrupt state during upgrades. Precision loss in arithmetic compounds undetected across thousands of transactions. Transient storage lifecycle boundaries create reentrancy vectors that traditional guards cannot catch. Flash loans manipulate oracles within single transactions. Governance mechanisms fail to account for multi-chain signature replay.

These aren't theoretical vulnerabilities, they're billion-dollar lessons the Web3 ecosystem has learned the hard way.

This Book Teaches You to See What Others Miss

Practical Blockchain Security for Developers is written by a senior smart contract auditor for practitioners who ship real protocols. It's a code-first guide that doesn't assume cryptography expertise or years studying EVM bytecode. Instead, it teaches you to reason about security from first principles, understanding exact EVM state mutations that enable attacks, tracing architectural flaws that create entire vulnerability classes, implementing hardened patterns that prevent compromise.

Every vulnerability covered includes: the exploit mechanics, vulnerable contract code, the attack vector, and production-ready remediation.

What You'll Master

Part I: Low-Level EVM Execution Security & State Mutability Mechanics Understand how DELEGATECALL creates context bifurcation attacks, how proxy upgrades cause storage collision exploits, why transient storage requires lifecycle management, how memory expansion enables denial-of-service, and how calldata corruption bypasses validation.

Part II: Advanced DeFi Invariants, Mathematics, and Token Standards Analyze non-standard ERC-20 behaviors that break accounting engines, master ERC-4626 vault mathematics where first-depositor inflation and precision loss compound into insolvency, trace flash loan plus oracle manipulation that bankrupts protocols, secure cross-chain communication channels against validator compromise and proof verification bugs.

Part III: The Foundry Automated Testing & Verification Harness Build property-based fuzzing discovering edge cases humans miss, differential testing proving optimized assembly matches pure Solidity, symbolic execution validating invariants across arbitrary state configurations.

Part IV: Enterprise Protocol Defense, Monitoring, and Threat Modeling Design layered governance immune to single key compromise, implement real-time mempool monitoring detecting attacks before execution, engineer post-exploit recovery frameworks for graceful state unwinding, architect incident response systems with automated circuit breakers.

Who This Book Is For

Protocol developers, security engineers, blockchain architects, security researchers - anyone shipping code that protects serious value.

Assumes: Solidity knowledge and blockchain basics.

Delivers: Original code examples, production-ready patterns, modern threat coverage (transient storage attacks, via-IR compiler vulnerabilities, cross-chain oracle lag exploitation, EIP-712 domain separator weaknesses).

All examples are original, compilable, and tested. Companion open-source repository includes live smart contracts, Foundry fuzzing harnesses, mempool monitoring automation, and complete testing suites.

The reality: Attacks don't just come in Web3, they're sophisticated, coordinated, and relentless. This book teaches you to build protocols that don't just survive them, but detect them in real-time and recover gracefully.
