Differential Review

Analyze differences between two versions of a MultiversX codebase, focusing on security implications of changes, storage layout compatibility, and upgrade safety.

When to Use

• Reviewing pull requests with contract changes
• Auditing upgrade proposals before deployment
• Analyzing differences between deployed code and proposed updates
• Verifying fix implementations don't introduce regressions
