A comprehensive reference documenting known Solidity smart contract attack vectors and common anti-patterns, hosted on GitHub as the basis for a Sigma Prime blog post and the Mastering Ethereum book. Each vulnerability is explained with its mechanics, preventative techniques, and real-world exploit examples like The DAO and the Parity wallet hacks.

Use cases

• learn common solidity smart contract vulnerabilities
• understand how the DAO reentrancy hack happened
• find preventative techniques for solidity security flaws
• study real-world ethereum exploit case studies
• review smart contract anti-patterns before an audit
• learn about delegatecall and parity wallet hacks
• understand arithmetic overflow vulnerabilities in solidity

When to choose

• you are learning solidity or ethereum smart contract security
• you need real-world examples of famous exploits like The DAO or Parity multisig hacks
• you want a curated checklist of attack vectors to review before writing or auditing contracts

When to avoid

• you need an automated vulnerability scanner or static analysis tool rather than educational material
• you need coverage of the latest vulnerabilities, as the content was last substantially updated in 2018
• you need executable code or a library rather than documentation
