Integer overflow remains a critical vulnerability in Ethereum smart contracts, often leading to significant financial losses in DeFi protocols. This article offers a practical guide for writing audit specifications that specifically target overflow risks. It outlines common overflow patterns, such as unchecked arithmetic operations, and provides clear mitigation strategies including the use of SafeMath libraries and Solidity's built-in overflow checks. The guide emphasizes the importance of comprehensive test coverage and formal verification in audit processes. For developers and security engineers, this resource serves as a concise checklist to integrate overflow prevention into their smart contract development lifecycle. Given the ongoing evolution of DeFi and the high value locked in smart contracts, such preventive measures are essential for maintaining trust and security in blockchain applications.
