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.
