Security Tools Overview

Blockchain Security Toolset​

At node.security, we employ a comprehensive suite of security tools to analyze and test blockchain projects. This overview introduces the categories of tools we use and how they fit into our security assessment process.

Tool Categories​

Static Analysis​

Static analysis tools examine code without executing it, identifying potential vulnerabilities through pattern matching, control flow analysis, and semantic understanding.

Key static analysis tools include:

  • Slither: Framework for Solidity static analysis
  • Mythril: Symbolic execution tool for smart contracts
  • Securify: Pattern-based security scanner

Dynamic Analysis​

Dynamic analysis tools observe contract behavior during execution, identifying vulnerabilities that might not be apparent from static code review.

Key dynamic analysis tools include:

  • Echidna: Fuzzing tool for Ethereum smart contracts
  • Foundry/Forge: Modern smart contract development toolchain
  • Hardhat: Development environment with testing framework

Formal Verification​

Formal verification uses mathematical methods to prove or disprove the correctness of a system with respect to a formal specification.

Key formal verification tools include:

  • Certora Prover: Formal verification for smart contracts
  • Manticore: Symbolic execution tool with formal verification capabilities

Custom Tools​

We also develop and maintain custom tools for specific analysis needs:

  • Token flow analyzers for DeFi protocols
  • Gas optimization analyzers
  • Contract dependency mappers
  • Protocol-specific security checkers

Integration Into Our Workflow​

Our security assessment process integrates these tools at different stages:

  1. Initial Scanning: Automated tools provide a baseline of potential issues
  2. Focused Analysis: Specialized tools drill down into specific areas of concern
  3. Validation: Tools help confirm the presence or absence of suspected vulnerabilities
  4. Verification: Tools verify that fixes correctly address identified issues

Benefits of Our Tooling Approach​

Comprehensive Coverage​

By combining multiple tools with different approaches, we maximize our coverage of potential vulnerability types.

Efficiency and Depth​

Automation handles routine checks, allowing our experts to focus on complex logic and business-specific vulnerabilities.

Consistency​

Standardized tooling ensures consistent analysis across projects and team members.

Continuous Improvement​

We regularly update and expand our toolset to address emerging threat vectors and improve detection capabilities.

Limitations and Complementary Approaches​

While tools are essential to our process, we recognize their limitations:

  • No tool can find all possible vulnerabilities
  • False positives and false negatives are inherent in automated analysis
  • Business logic flaws often require human expertise to identify
  • Novel attack vectors may not be covered by existing tools

For these reasons, we combine tooling with manual review, economic analysis, and experience-based assessment to provide comprehensive security evaluations.
