What It Detects

CRITICAL (Funds at risk)

· Reentrancy (cross-function, complex patterns) · Unchecked external calls (call/delegatecall/transfer/send) · Access control violations (critical functions without checks) · Tainted data flows (user input → dangerous operations) · Delegatecall risks (user-controlled delegatecall)

MEDIUM (Logic flaws)

· Timestamp dependence (block.timestamp for randomness) · Front-running vulnerabilities (missing slippage/deadline) · Gas limit issues (unbounded loops, storage thrashing) · Arithmetic overflows (without unchecked blocks) · Tx.origin misuse

CODE QUALITY

· Selfdestruct usage · Assembly risks · Deprecated patterns (now, suicide, etc.)

Quick Start

1. Try Online (No Installation)

Live Demo: https://smartshield-demo-m0tw.onrender.com/#scanner

2. Use as Library

npm install solidity-industrial-scanner

const { IndustrialSecurityScanner } = require('solidity-industrial-scanner');

const scanner = new IndustrialSecurityScanner(sourceCode);
const results = scanner.scan();

console.log(results.vulnerabilities); // Array of found issues

3. Command Line

npx solidity-industrial-scanner -f contract.sol

Real Examples Found

Example 1: Cross-function Reentrancy (Most tools miss this)

// VULNERABLE CONTRACT
contract Bank {
    mapping(address => uint) balances;
    
    function withdraw() external {
        uint amount = balances[msg.sender];
        (bool success, ) = msg.sender.call{value: amount}(""); // CALL
        require(success);
    }
    
    function updateBalance() external {
        balances[msg.sender] = 0; // STATE CHANGE in DIFFERENT function
    }
}

THIS SCANNER FINDS: "Reentrancy: external call in withdraw() can re-enter through updateBalance()" OTHER SCANNERS MISS: They only check within single function

Example 2: Tainted Data Flow

function adminOperation(address user) external {
    // user comes from msg.sender (tainted source)
    executeCritical(user); // TAINTED DATA → CRITICAL OPERATION
}

function executeCritical(address target) internal {
    target.delegatecall(/* ... */); // Dangerous if user-controlled
}

Loading

Key Components:

· IndustrialParser – Tolerant parsing (works on incomplete code) · CallGraph – Maps function relationships across contracts · SymbolicExecutor – Explores execution paths mathematically · TaintTracker – Follows untrusted data through the program · InterproceduralAnalyzer – Finds vulnerabilities across functions

Advanced Usage

Custom Configuration

const scanner = new IndustrialSecurityScanner(sourceCode, {
    ENABLE_SYMBOLIC_EXECUTION: true,
    ENABLE_TAINT_ANALYSIS: true,
    ENABLE_INTERPROCEDURAL: true,
    TIMEOUT_MS: 10000,
    TOLERANT_MODE: true // Works on partial code
});

Integration Examples

· Remix IDE Plugin – In-browser deep analysis · CI/CD Pipeline – Pre-commit security checks · Hardhat/Froundry Tasks – Local development scanning

Contributing

Found a bug? Have an idea for a new detector?

1. Report an Issue – Include minimal reproducible code
2. Add a Detector – See src/checks/ for examples
3. Improve Analysis – Symbolic execution, taint tracking

Priority Detectors Needed:

· Flash loan attack patterns · Oracle manipulation · Governance attacks
