Smart contract security is holding back developers
Security barriers block innovation
Most developers lack access to security tools, leading to vulnerable contracts reaching mainnet.
Expensive audits exclude small teams
Quality security feedback requires costly audits that newcomers and hackathon participants can't afford.
Learning curve prevents adoption
Existing tools are command-line focused and lack educational context for new Solidity developers.
"Security tools are gatekeeping. We need accessible solutions that teach while protecting." - Ethereum Developer
Kytona makes security accessible and educational
GitHub-integrated security scanning
Automatic vulnerability detection on every pull request with zero setup required.
Educational feedback system
Each vulnerability includes explanations, fix suggestions, and links to learning resources.
Community-driven rules
Open source detection patterns that anyone can contribute to and improve.

How Kytona works
Automated security scanning that integrates into your development workflow.
Install the GitHub App
# Add Kytona to your repository
# github.com/apps/kytona
✅ Zero configuration required
✅ Works with any Solidity project
✅ Respects your existing workflowCreate a pull request with contract changes
// contracts/Token.sol
function withdraw(uint amount) public {
require(balances[msg.sender] >= amount);
- msg.sender.call{value: amount}("");
+ balances[msg.sender] -= amount;
+ msg.sender.call{value: amount}("");
}

⚠️ High Severity: Reentrancy Vulnerability
Your code changes state after an external call.
📚 Learn: Understanding Reentrancy Attacks
🔧 Fix: Move balance update before external call
🎯 Try: Interactive vulnerability demoBuilt for secure smart contracts
Intelligent vulnerability detection
Advanced static analysis detects reentrancy, overflow, access control, and other critical vulnerabilities
