Static Analysis Scanners

Slither

Best for: Comprehensive vulnerability detection

Aspect Detail
Speed Fast (seconds)
Coverage Broad (80+ detectors)
False Positives Low-Medium
Strengths Reentrancy, access control, data flow

When to use: Every scan. Foundation of analysis.

Solhint

Best for: Code quality and style

Aspect Detail
Speed Very fast
Coverage Style, best practices
False Positives Low
Strengths Naming, formatting, gas

When to use: Code review, PR checks.

Aderyn

Best for: Modern Solidity patterns

Aspect Detail
Speed Fast
Coverage Security + quality
False Positives Low
Strengths Modern patterns, Rust-based speed

When to use: Modern codebases, Foundry projects.

Semgrep

Best for: Custom rule matching

Aspect Detail
Speed Fast
Coverage Pattern-based
False Positives Low (depends on rules)
Strengths Custom rules, specific patterns

When to use: Known vulnerability patterns, compliance.

Wake

Best for: Framework-aware analysis

Aspect Detail
Speed Medium
Coverage Deep analysis
False Positives Low
Strengths Import resolution, complex projects

When to use: Large projects with many dependencies.

Formal Verification

Mythril

Best for: Deep symbolic execution

Aspect Detail
Speed Slow (minutes-hours)
Coverage Path exploration
False Positives Low
Strengths Integer issues, state manipulation

When to use: Deep audits, critical contracts.

Halmos

Best for: Symbolic testing

Aspect Detail
Speed Medium-Slow
Coverage Property-based
False Positives Very low
Strengths Bounded model checking

When to use: When you have properties to verify.

Certora

Best for: Formal specifications

Aspect Detail
Speed Slow
Coverage Specification-based
False Positives Very low
Strengths Proving correctness

When to use: Critical DeFi, custom specifications.

Fuzz Testing

Echidna

Best for: Property-based fuzzing

Aspect Detail
Speed Slow (many iterations)
Coverage Invariant testing
False Positives Very low
Strengths Finding edge cases

When to use: Testing invariants, complex logic.

Requires: Invariant functions in code

function echidna_balance_positive() public view returns (bool) {
    return balance >= 0;
}

Medusa

Best for: Parallel fuzzing

Aspect Detail
Speed Faster than Echidna
Coverage Similar to Echidna
False Positives Very low
Strengths Parallelization, speed

When to use: Large fuzzing campaigns, time-constrained.

AI-Powered

SolidityDefend

Best for: Novel vulnerability patterns

Aspect Detail
Speed Fast
Coverage ML-based patterns

  • Solhint
  • Aderyn

Duration: ~30 seconds
Coverage: Basic security + quality

Standard Preset

For thorough review:

  • Slither, Solhint, Aderyn
  • Semgrep
  • Wake

Duration: 2-5 minutes
Coverage: Comprehensive static analysis

Deep Preset

For full audit:

  • All static analyzers
  • Mythril
  • Echidna/Medusa

Duration: 10-30 minutes
Coverage: Maximum

Custom Scanner Selection

For DeFi Audits

Prioritize:

  1. Slither (reentrancy, access)
  2. Mythril (symbolic execution)
  3. Echidna (invariants)

For Token Audits

Prioritize:

  1. Slither (ERC compliance)
  2. Aderyn (modern patterns)
  3. Solhint (standards)

For NFT Audits

Prioritize:

  1. Slither (access control)
  2. Semgrep (metadata patterns)
  3. Aderyn (royalty patterns)

Scanner Limitations

Scanner Misses
Slither Complex business logic
Mythril State space explosion
Echidna Without properties
All Economic attacks

Always combine automated scanning with manual review.
