SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Blockchain security is critical for smart contracts, DeFi protocols, and on-chain systems; this Skill helps identify, assess, and remediate vulnerabilities across the entire stack.

Core Features & Use Cases

  • Smart contract auditing: detect common patterns that enable reentrancy, overflow, and access-control flaws.
  • DeFi exploit detection: evaluate oracles, flash loans, governance risks, and token mechanics.
  • On-chain risk assessment: review cross-chain bridges, NFT marketplaces, and token contracts for resilience.
  • Use Case: apply to a target with Solidity sources and contract addresses to generate a prioritized vulnerability list with reproducible steps.

Quick Start

Provide a comprehensive security assessment of a smart contract target by applying a structured audit checklist and delivering actionable remediation steps.

FAQPage Schema
How do I audit smart contracts for reentrancy and access control vulnerabilities?

To perform a smart contract security audit, provide Solidity or Vyper source code and contract addresses for structured threat modeling. The assessment identifies vulnerabilities like reentrancy and access control flaws, then generates actionable remediation guidance with reproducible evidence for each detected issue.

What is DeFi exploit detection and how does it evaluate oracle manipulation risks?

DeFi exploit detection evaluates protocols for oracle manipulation, flash loan attacks, governance risks, and token mechanics by analyzing on-chain patterns. It identifies complex exploit vectors and generates prioritized vulnerability lists with reproducible remediation steps to secure DeFi systems.

Can I assess cross-chain bridge security and NFT marketplace resilience?

Yes, you can assess cross-chain bridge and NFT marketplace resilience by analyzing contract addresses and cryptographic interactions. The Skill reviews token contracts and on-chain components to identify access control flaws and proxy pattern vulnerabilities, delivering a structured on-chain risk assessment.

Does this security audit approach work with Vyper and Solidity protocols?

Yes, this security audit approach supports both Vyper and Solidity source code for analyzing DeFi protocols, governance contracts, and cross-chain bridges. It applies structured threat modeling to identify vulnerabilities like integer overflow and proxy pattern flaws, producing remediation guidance with reproducible evidence.

What's the best way to generate reproducible evidence for a smart contract vulnerability?

Generate reproducible evidence by applying structured threat modeling to the target's Solidity sources and contract addresses. This process identifies specific flaws like reentrancy or access control issues and outputs actionable remediation guidance with step-by-step reproduction evidence.

When do I need a proactive security audit for blockchain code?

You need a proactive security audit when deploying smart contracts, DeFi protocols, or cross-chain bridges to identify reentrancy, integer overflow, and access control vulnerabilities. It is essential before handling on-chain assets to ensure governance, oracle, and token mechanics are resilient.
