The Preparation Process

Step 1: Set Review Goals

Helps define what you want from the review:

Key Questions:

• What's the overall security level you're aiming for?
• What areas concern you most?
  • Previous audit issues?
  • Complex components?
  • Fragile parts?
• What's the worst-case scenario for your project?

Documents goals to share with the assessment team.

Step 2: Resolve Easy Issues

Runs static analysis and helps fix low-hanging fruit:

Run Static Analysis:

For Solidity:

slither . --exclude-dependencies

For Rust:

dylint --all

For Go:

golangci-lint run

For Go/Rust/C++:

# CodeQL and Semgrep checks

Then I'll:

• Triage all findings
• Help fix easy issues
• Document accepted risks

Increase Test Coverage:

• Analyze current coverage
• Identify untested code
• Suggest new tests
• Run full test suite

Remove Dead Code:

• Find unused functions/variables
• Identify unused libraries
• Locate stale features
• Suggest cleanup

Goal: Clean static analysis report, high test coverage, minimal dead code

Step 3: Ensure Code Accessibility

Helps make code clear and accessible:

Provide Detailed File List:

• List all files in scope
• Mark out-of-scope files
• Explain folder structure
• Document dependencies

Create Build Instructions:

• Write step-by-step setup guide
• Test on fresh environment
• Document dependencies and versions
• Verify build succeeds

Freeze Stable Version:

• Identify commit hash for review
• Create dedicated branch
• Tag release version
• Lock dependencies

Identify Boilerplate:

• Mark copied/forked code
• Highlight your modifications
• Document third-party code
• Focus review on your code
