Soroban Best Practices Rule Pack

The Soroban Best Practices Rule Pack extends GasGuard beyond vulnerability detection by providing actionable recommendations for writing secure, maintainable, and efficient Soroban smart contracts. Instead of identifying only exploitable security issues, this rule pack helps developers adopt coding patterns that align with the Stellar ecosystem's recommended practices.

Overview

Located in:

src/rules/best-practices/stellar/

This rule pack analyzes Soroban contracts for common best-practice violations and generates findings that improve code quality, readability, maintainability, and long-term reliability.

Features

• ✅ Detects deviations from Soroban development best practices
• ✅ Categorizes findings by type and severity
• ✅ Supports configurable rule sets
• ✅ Generates clear, actionable recommendations
• ✅ Complements GasGuard's security vulnerability scans

Rule Categories

The rule pack can include checks such as:

• Code organization and readability
• Storage access best practices
• Authorization and access control recommendations
• Error handling and panic avoidance
• Event emission consistency
• Resource optimization and efficient storage usage
• Maintainability and developer experience improvements
• General Soroban development guidelines

Configuration

Rules can be enabled, disabled, or customized to match a project's coding standards and security requirements.

Example:

best-practices:
  enabled: true
  rules:
    storage-efficiency: warning
    authorization-patterns: error
    event-consistency: warning
    panic-usage: info

Example Finding

Rule: storage-efficiency
Severity: Warning

Repeated storage lookups detected within the same execution path.

Recommendation:
Cache the storage value locally to reduce unnecessary storage access and improve contract performance.

Benefits

• Encourages consistent Soroban development practices
• Improves contract quality before deployment
• Reduces technical debt and maintenance costs
• Helps developers write cleaner, more efficient smart contracts
• Works alongside security rules to provide comprehensive contract analysis

Acceptance Criteria

• ✔ Rule pack implemented
• ✔ Findings generated successfully
• ✔ Configurable rule support
• ✔ Categorized best-practice recommendations
