The problem

$3.8 billion lost to smart contract exploits in 2024

Manual audits cost $5K–$50K and take weeks. Most contracts ship without any security review. The gap between “deployed” and “audited” is where attackers live.

Vault.sol — reentrancy vulnerability
function withdraw(uint amount) public {
    require(balances[msg.sender] >= amount);
    (bool ok,) = msg.sender.call{value: amount}("");    require(ok);
    balances[msg.sender] -= amount;  // ← state after external call
}
Classic ReentrancyCritical

External call on line 3 sends ETH before updating state on line 5. An attacker can re-enter withdraw() and drain the vault.

Fix: checks-effects-interactions pattern

Our scanner catches this in 0.3s. The AI layer explains the risk and suggests the exact fix.

How it works

Three layers of security analysis

01

Parse & Analyze

Upload Solidity source or paste a contract address. Our engine parses the AST and builds a complete control-flow graph.

Slither-powered parsing
02

Detect & Scan

10+ specialized detectors run in parallel — reentrancy, access control, integer overflow, unchecked calls, and more.

Static analysis + pattern matching
03

AI Deep Review

AI performs multi-pass analysis, understanding business logic and finding subtle vulnerabilities that static tools miss.
