Introducing OdinScan: AI-Powered Smart Contract Security

Why We Built OdinScan

Smart contract security is hard. Traditional audits are expensive, slow, and often happen too late in the development cycle. We built OdinScan to change that, bringing AI-powered security analysis to every developer, at every stage of development.

The Problem with Traditional Audits

Most security audits today follow a manual review process:

1. Long wait times: weeks or even months to get scheduled
2. High costs: $50k–$250k+ per audit depending on complexity
3. Point-in-time snapshots: code changes after the audit invalidate findings
4. Human error: even experienced auditors miss subtle vulnerabilities

Our Approach: Multi-Model Cross-Validation

OdinScan uses multiple AI models that cross-validate each other's findings. This dramatically reduces false positives while catching vulnerabilities that single-model approaches miss.

// Example: Reentrancy vulnerability detected by OdinScan
contract Vulnerable {
    mapping(address => uint256) public balances;

    function withdraw() external {
        uint256 balance = balances[msg.sender];
        // OdinScan flags this: external call before state update
        (bool success, ) = msg.sender.call{value: balance}("");
        require(success, "Transfer failed");
        balances[msg.sender] = 0; // State update after external call
    }
}

OdinScan would flag this contract with a Critical severity reentrancy finding, complete with a suggested fix:

// Fixed version following checks-effects-interactions pattern
contract Secure {
    mapping(address => uint256) public balances;

    function withdraw() external {
        uint256 balance = balances[msg.sender];
        balances[msg.sender] = 0; // State update BEFORE external call
        (bool success, ) = msg.sender.call{value: balance}("");
        require(success, "Transfer failed");
    }
}
