Smart Contract Analyzer

Analyze Solidity smart contracts for security vulnerabilities, gas optimizations, and best practices

Supports Solidity 0.4.x to 0.8.x. Analysis is performed client-side - your code never leaves your browser.

About Smart Contract Analysis

Our Smart Contract Analyzer performs automated security audits on Solidity smart contracts, checking for:

Security Vulnerabilities

  • • Reentrancy attacks
  • • Access control issues
  • • Integer overflow/underflow
  • • Unchecked external calls
  • • Dangerous delegatecall usage
  • • Weak randomness
  • • Front-running vulnerabilities
  • • Denial of Service risks

Best Practices

  • • Function visibility
  • • Event emission
  • • NatSpec documentation
  • • Deprecated functions
  • • Gas optimizations
  • • Storage packing
  • • Code quality metrics
  • • Solidity version checks

⚠️ Important: This tool provides automated analysis and should not replace professional security audits. Always have your production smart contracts audited by experienced security professionals before deploying to mainnet.
