Prevent smart contract exploits
block reentrancy, overflow, and access control bypasses before they succeed.
Secure user interactions
detect phishing attempts and malicious wallet connections in real time.
Protect hybrid infrastructure
monitor both Web2 backends and Web3 contracts to stop cross-layer exploits.
Audits Are Just the Beginning
Over 90% of hacks happen in audited protocols after deployment.
Static audits catch code bugs pre-launch, but can't defend against the live threats that emerge in production. Guardrail provides the continuous monitoring that protects your protocol 24/7 where real attacks happen.
Why monitoring?
DApps are the fastest-growing sector of Web3, but in 2023 alone, they suffered over $1.9 billion in losses from exploits. With hybrid infrastructures combining smart contracts, frontend interfaces, and backend APIs, DApps face unique attack surfaces.
Smart contract and logic exploits
that enable reentrancy attacks, integer overflows, and access control bypasses to instantly drain user funds.
.avif)
Client-side wallet and transaction manipulation
where malicious frontend code tricks users into signing unauthorized transactions or connecting to fake contracts.
.avif)
Hybrid Web2/Web3 attack vectors
where backend API vulnerabilities lead to private key theft and smart contract ownership takeover.
.avif)
Third-party integration and dependency risks
where vulnerable external libraries, oracles, and API integrations compromise entire DApp ecosystems.

Real-time threat monitoring is now a baseline requirement for DApps and Web3 applications
Threat
Why it matters
Guardrail real-time monitoring
Smart Contract & Logic Exploits
Vulnerable contract code enables reentrancy attacks, integer overflows, and access control bypasses that can instantly drain user funds or manipulate application state.
Reentrancy detection & abnormal execution monitoring
Client-Side Wallet & Transaction Manipulation
Malicious frontend code and compromised interfaces trick users into signing unauthorized transactions or connecting to fake contracts that steal assets.
Transaction approval tracking & malicious signature detection
Hybrid Web2/Web3 Attack Vectors
Backend API vulnerabilities and server-side compromises can lead to the theft of private keys, takeover of smart contract ownership, and complete control over the application.
Admin action monitoring & ownership transfer alerts
Phishing & Social Engineering Attacks
Fake DApp UIs and spoofed domains steal wallet credentials or assets.
Wallet behavior analysis & rapid approval detection
Cross-Chain & Bridge Integration Risks
Multi-chain DApp functionality introduces bridge vulnerabilities and cross-chain attack vectors that can compromise assets across multiple networks.
Cross-chain reconciliation & bridge exploit detection
Frontend Security & XSS Vulnerabilities
Client-side code injections and browser-based attacks can manipulate user interfaces to steal tokens or redirect transactions to attacker-controlled addresses.
Address verification & transaction redirection prevention
Third-Party Integration & Dependency Risks
Vulnerable external libraries, oracles, and API integrations create attack surfaces that can compromise entire DApp ecosystems and user funds.
Dependency monitoring & oracle cross-verification

Frequently asked questions
Need more information?
What is real-time security monitoring for DApps?
Comprehensive surveillance of smart contracts, frontends, backends, and user interactions to detect threats before they compromise funds or application integrity.
Why are DApps more vulnerable than traditional apps?
They combine Web2 and Web3 components. A weakness in contracts, APIs, or frontend code can be exploited instantly, often before the team notices.
Can Guardrail detect malicious wallet prompts or phishing UIs?
Yes. Guardrail monitors wallet connections and transaction flows, flagging suspicious prompts or unauthorized signing attempts.
How does Guardrail secure backend APIs in hybrid DApps?
It tracks API activity, ownership controls, and unusual requests, identifying backend compromises that could lead to contract takeovers.
Does Guardrail support multi-chain DApps?
Yes. Guardrail monitors cross-chain bridges and token flows to detect anomalies and prevent exploits across different networks.
