Security Checklist Compliance Validator

WHAT IT DOES

Security Checklist Compliance Validator is a security-focused tool that validates Solidity contracts against customizable security checklists. It takes contract source code and a security checklist (user-provided or default) from the user, then analyzes the source code for compliance with each checklist item. The tool checks for patterns including SafeMath usage, onlyOwner modifiers, events, require statements, reentrancy protection, block.timestamp usage, zero address checks, pause functionality, OpenZeppelin imports, and many other security best practices. Each checklist item is evaluated and assigned a status: pass, fail, warning, or info. Results are displayed with a summary showing the number of items passed, failed, and warnings, along with a compliance rate percentage. Detailed findings include the item description, status, specific details about the detection, and recommendations for failed or warning items. This enables developers to quickly assess the security posture of their contracts against industry best practices.

HOW TO USE

Paste your Solidity contract source code into the input area. Optionally, enter a custom security checklist as a JSON array of strings. Leave the checklist empty to use the default checklist of 25 common security best practices. Click "Validate compliance" to analyze the code. The tool will display a summary showing the total number of items, passed, failed, warnings, and the compliance rate. Each checklist item is displayed with its status, a detailed description of what was found, and recommendations for failed or warning items. The report can be copied or downloaded as JSON.

TECHNICAL NOTE: PATTERN-BASED SECURITY CHECKLIST VALIDATION

The tool uses regex-based pattern matching to detect security patterns in Solidity source code. It checks for specific keywords, function signatures, library imports, and structural patterns that indicate compliance with each checklist item. For example, it looks for SafeMath or Solidity 0.8+ overflow protection, onlyOwner modifiers, event definitions, require statements, nonReentrant modifiers, block.timestamp usage, address(0) checks, and pause functionality. Each checklist item is mapped to one or more patterns, and the tool evaluates the source code against these patterns. If a pattern is found, the item passes; if not, it fails or generates a warning. The tool also provides recommendations for failed items based on the specific security best practice.

WHAT IT CANNOT SEE

The tool cannot detect all security issues without context; some patterns may be safe or unsafe depending on the specific application logic. It is limited to the accuracy of the source code analysis; syntax variations may cause false positives or negatives. It cannot detect issues in external contracts or libraries that are imported into the contract. It cannot verify if a checklist item is actually exploitable in the specific deployment environment. The tool is limited by the parser's ability to handle Solidity syntax variations, including newer language features. It cannot validate security for non-EVM chains.

PLEASE NOTE

This tool is designed exclusively for Solidity contracts on EVM-compatible chains. It does not support other smart contract languages. The validation is based on static analysis and may produce false positives or miss some issues. The checklist is a general set of best practices and may not be applicable to all contracts. Always verify the findings with manual review and comprehensive security testing. The tool is read-only and does not modify any state. The tool provides no warranty that the validation results are complete or accurate; users are responsible for validating all findings and implementing appropriate fixes.
