C4Udit

C4Udit is a Go command-line static analyzer that scans Solidity source files with regular-expression patterns tailored to Code4rena contests, reporting selected low-risk issues and gas optimizations from c4-common-issues.

Understand the project

Practical overview

When it fits

Use it as a focused pattern scan before or during manual Solidity code review, or to produce a Markdown record of findings.

Who it is for

  • Solidity developers reviewing contract source code.
  • Code4rena contest participants who want to surface the issue patterns covered by the analyzer.

Documented uses

  • Scan Solidity files for documented low-risk issue and gas-optimization patterns.
  • Review findings in the terminal with source locations and issue identifiers.
  • Save scan results as a Markdown report.
Before you choose

Requirements & limits

The public GitHub repository lists the project under the GPL-3.0 license. The README requires the Go toolchain for installation or building.

  • The checks are regular-expression-based and limited to documented patterns; they do not constitute a comprehensive contract security assessment.
  • The -s flag saves findings as a Markdown report; otherwise, the README shows terminal output.
  • The tool is a Go CLI that accepts file paths or directories.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Scan Solidity files and save a Markdown report

Run C4Udit against Solidity files and request a report file.

Before you start

  • C4Udit installed or built
  • Solidity source files or a directory containing them

Steps

  1. Run c4udit [files...] with the file paths or directory to analyze.

  2. Add the -s flag to save the report as a Markdown file.

Expected outcome

C4Udit prints findings and, with `-s`, creates a Markdown report.

Guide limitations

  • The analyzer checks documented regular-expression patterns; its output is limited to the issue and optimization patterns it covers.
