With the recent news of Defender's end-of-life announcement, we're excited to share Guardrail's capabilities for teams looking to avoid downtime and ensure a smooth transition.
Why DeFi teams migrate from Defender
OpenZeppelin Defender handles essential monitoring: watching for specific events, sending alerts, and running simple automated responses. As protocols mature, teams often need enhanced capabilities and hit walls due to that.
Defender's autotasks require custom TypeScript for anything beyond basic alerts. Adding new monitoring logic means developer time. Multi-chain support is limited. Usage limits can become restrictive as your protocol grows. Focused primarily on automation, Defender relies on external security intelligence and hands-on configurations for advanced security checks.
Guardrail's ‘Guard’ system handles everything Defender does, plus invariant checks, anomaly detection, and custom security logic.
What Guardrail's real-time security platform provides instead
- Enhanced smart contract monitoring with built-in intelligence. Guardrail's Guard system offers a comprehensive solution that surpasses OpenZeppelin Defender's capabilities. It covers all Defender's functionalities and also incorporates invariant checks, anomaly detection, and highly customizable security logic.
- Configuration is handled seamlessly through our intuitive interface, eliminating the need for manual coding. Our extensive pre-built catalogue provides templates for prevalent DeFi risks, leverages ML-powered exploit detection, and offers protocol-specific checks for robust security.
- Better DeFi automation options. Choose between hosting your own webhook service or using our smart contract automation. Both approaches give you more control than Defender's autotasks.
- Comprehensive multi-chain security. We run on 25+ chains and add new ones overnight when needed.
Guardrail addresses the real-time security gap by consolidating and simplifying hyper-specific monitoring efforts and adhoc incident response. It offers a simple, intelligent, and multi-chain continuous security platform.
FAQs - common smart contract migration questions
Will my existing monitoring work?
- Yes. We recreate your Defender monitoring rules as Guardrail guards, often with improvements you couldn't implement in Defender.
How long does migration take?
- In most cases, migration takes one week.
- Our team works closely with you to mirror and enhance your live monitoring setup.
What code changes are needed?
- Minimal. Mostly updating webhook URLs if you use Defender's notifications.
- For autotasks, we help recreate the logic using our automation system.
Can I test before switching?
- Absolutely. We set up live monitoring for your contracts so you can compare both platforms before deciding.
Which chains do you support?
- All major EVM chains, including Ethereum, Base, Arbitrum, Optimism, and Polygon. We add new chains as needed.
- OpenZeppelin Defender provides a foundation for smart contract monitoring, where Guardrail extends its security application to be end-to-end, intelligent, and automated to outgrow its limitations. Guardrail offers the same core functionality with real-time security monitoring enhancements and greater flexibility around the same price points.
Stop preventable exploits before they happen.
DeFi loses funds to hacks every 1.3 days on average. While Defender provides basic monitoring, Guardrail delivers real-time adaptive security that catches threats others miss.
Join protocols like Euler, Eigenlayer, and Avantis, who trust Guardrail to secure their smart contracts.
Ready to upgrade your protocol security?
Guardrail is a continuous monitoring, detection & response web3 security platform. We give protocols real-time visibility to catch issues continuously, prevent costly exploits, and protect what matters onchain.
To get started with Guardrail, schedule a security monitoring consultation.
Our security research team will analyze your current Defender setup and demonstrate how Guardrail's advanced monitoring capabilities proactively prevent exploits in real-time, catching threats that other tools typically miss.
