integer-overflow

What problem does it solve?

This skill provides integer safety patterns for Solidity 0.8+ to prevent overflow and underflow by default, including guidance on unchecked blocks, safe casting, and handling phantom overflow.

Core Features & Use Cases

• Automatic checks in Solidity 0.8+ prevent common overflow errors.
• Unchecked blocks for performance where overflow is mathematically impossible.
• Phantom overflow patterns and safe casting using libraries like SafeCast or FixedPointMathLib.
• Practical examples and best practices for avoiding truncation and integer edge cases.

Quick Start

Review a Solidity snippet and implement safe arithmetic patterns to eliminate overflow risks.
