Just provide contract addresses. * **Deploy guards** — Choose from our blueprint library or work with our team on custom monitoring. * **Get alerts** — Slack, Discord, PagerDuty, Telegram, or webhooks. Sub-second delivery. * **Respond** — Manually investigate or trigger automated responses. ## Why Audits Aren't Enough The biggest DeFi hacks of 2024-2025—Cetus ($224M), Radiant ($50M), WazirX ($230M)—all happened on audited code. Audits verify code at a point in time. They can't catch: * **Runtime attacks** — Flash loans, price manipulation, reentrancy during execution * **Governance exploits** — Compromised multisigs, malicious proposals * **Economic attacks** — Oracle manipulation, MEV exploits * **Upgrade vulnerabilities** — Uninitialized proxies, storage collisions Guardrail monitors what actually happens on-chain, in real-time. ## Next Steps * [Explore Use Cases →](https://github.com/CryptoGuardrail/docs-v3-external/blob/main/use-cases/README.md) * [View Guard Catalog →](https://github.com/CryptoGuardrail/docs-v3-external/blob/main/guards/README.md) * [See Case Studies →](https://github.com/CryptoGuardrail/docs-v3-external/blob/main/case-studies/README.md) For setup guides and configuration details, log in to access [App Documentation →](https://docs.guardrail.ai/app/) *** # How It Works Guardrail's platform connects to EVM RPC nodes with archive and tracing support. We index every transaction in real-time and run your configured guards against relevant state changes.
## Architecture Overview {% @mermaid/diagram content="flowchart LR A\[Blockchain
RPC Node] --> B\[Guardrail
Indexer] B --> C\[Your Alert
Channels] B --> D\[Guard
Processors]" %} **Indexer** — Subscribes to new blocks and indexes transactions with full trace data. Supports archive queries for historical state. **Guard Processors** — Stateless checks that evaluate transactions against your configured rules. Each guard has trigger conditions (when to run) and alert conditions (when to notify). **Response System** — Delivers alerts to your channels and can trigger automated responses like contract pauses or webhook calls. ## Detection Speed Guards trigger on transaction confirmation. Alert delivery is typically under 1 second from block finality. For chains with fast block times, this means near-instant detection. ## What Makes Us Different **Custom over generic** — Other tools send generic alerts. We build monitoring that understands your protocol's unique risks, economic model, and business logic. **Full trace access** — We analyze the complete execution path of transactions, including internal calls, not just top-level events. **Simulation support** — Test guards against historical transactions before deploying. Replay any transaction to see what would have triggered. *** # Overview Guardrail protects protocols across DeFi. Here's how different protocol types use our monitoring. ## By Protocol Type * [Lending & Borrowing](https://github.com/CryptoGuardrail/docs-v3-external/blob/main/use-cases/lending/README.md) * [DEXs & AMMs](https://github.com/CryptoGuardrail/docs-v3-external/blob/main/use-cases/dex/README.md) * [Bridges & Cross-Chain](https://github.com/CryptoGuardrail/docs-v3-external/blob/main/use-cases/bridges/README.md) * [Governance & DAOs](https://github.com/CryptoGuardrail/docs-v3-external/blob/main/use-cases/governance/README.md) ## Common Attack Vectors We Detect | Attack Type | Description | Example Incident | | ------------------------- | ------------------------------------------------------------------- | ---------------------- | | Flash Loan Attacks | Borrowed funds used to manipulate state within a single transaction | Euler 2023 ($197M) | | Price Oracle Manipulation | Exploiting price feeds to borrow/mint more than collateral allows | Polter Finance ($8.7M) | | Reentrancy | Functions called recursively before state updates complete | Penpie ($27M) | | Governance Exploits | Compromised signers or malicious proposals | Radiant Capital ($50M) | | Uninitialized Proxies | Upgrade contracts deployed without proper initialization | Ronin Bridge ($12M) | | Private Key Compromise | Stolen keys used to drain funds or change ownership | WazirX ($230M) | *** # Lending & Borrowing Lending protocols face unique risks around liquidations, oracle dependencies, and interest rate mechanics. ## Key Risks * **Liquidation cascades** during market volatility * **Bad debt accumulation** from underwater positions * **Oracle manipulation** to borrow against inflated collateral * **Interest rate attacks** exploiting utilization curves ## Guards We Deploy **Liquidation Monitoring** — Track liquidation events, detect cascades, alert on unusual liquidation patterns. **Oracle Health** — Monitor price feed deviations, detect stale prices, flag manipulation attempts. **Bad Debt Detection** — Identify positions with negative equity before they become protocol losses. **Utilization Alerts** — Track pool utilization and interest rate spikes. ## Case Study: Euler Labs > "Guardrail excels in price monitoring and price deviation by far compared to any of the tools in the market." — Erik Arfvidson, Head of Cybersecurity Euler consolidated from 3 monitoring tools to 1, with automated guard updates for new vault deployments. [Read full case study →](https://www.guardrail.ai/case-studies/euler-labs) *** # DEXs & AMMs Decentralized exchanges are targets for price manipulation, sandwich attacks, and liquidity exploits. ## Key Risks * **Price manipulation** via flash loans or large trades * **Sandwich attacks** extracting value from user swaps * **Liquidity removal** draining pools unexpectedly * **Pool parameter changes** modifying fees or weights maliciously ## Guards We Deploy **Pool Manipulation Detection** — Alert on abnormal price movements within single transactions. **Flash Loan Monitoring** — Flag transactions combining flash loans with large outflows. **Liquidity Drop Alerts** — Detect sudden liquidity removals that could impact trading. **MEV Protection Monitoring** — Track sandwich attack patterns affecting your users. ## Protocols Using Guardrail Avantis, Solo Labs, and other perpetual and spot exchanges trust Guardrail for real-time monitoring. *** # Bridges & Cross-Chain Bridges are high-value targets—over 50% of DeFi losses come from bridge exploits. Cross-chain verification requires specialized monitoring. ## Key Risks * **Message validation failures** between source and destination chains * **Mint/burn mismatches** creating unbacked tokens * **Relay manipulation** submitting fraudulent cross-chain messages * **Upgrade vulnerabilities** in bridge contracts ## Guards We Deploy **Cross-Chain Message Matching** — Verify bridged amounts match between source and destination. **Mint/Burn Limits** — Alert when token minting exceeds expected thresholds. **Bridge Relay Monitoring** — Track relay operations and flag anomalies. **Upgrade Event Guards** — Monitor proxy upgrades and initialization calls. ## Case Study: Concero > "No one can tell me anything that will convince me not to use Guardrail." — Andy Bohutsky, Founder 1-day implementation with real-time cross-chain message validation. [Read full case study →](https://www.guardrail.ai/case-studies/concero) *** # Governance & DAOs Governance attacks don't exploit code—they exploit trust and process. Monitoring operational security is as important as smart contract security. ## Key Risks * **Multisig compromise** from phished or malware-infected signers * **Malicious proposals** passing through governance * **Admin key rotation** to attacker-controlled addresses * **Treasury drains** via governance mechanisms ## Guards We Deploy **Multisig Threshold Monitoring** — Alert if signing requirements drop below safe levels. **Admin Change Detection** — Track ownership transfers and role changes. **Proposal Monitoring** — Flag unusual governance activity. **Treasury Movement Alerts** — Detect large or unusual treasury transactions. ## Case Study: BadgerDAO > "Guardrail provides peace of mind, tying directly into our PagerDuty system and actively monitoring critical positions. We've avoided costly liquidation events thanks to timely alerts." — Saj Raj, Core Contributor [Read full case study →](https://www.guardrail.ai/case-studies/badger) *** # Threat Intelligence Guardrail's security research team tracks DeFi exploits and attack patterns. Here are highlights from recent years showing how real-time monitoring could have prevented major losses. ## 2025 Highlights **Cetus Protocol ($224M) — June 2025** A concentrated liquidity DEX on Sui exploited through price calculation manipulation. Attackers drained multiple pools by exploiting arithmetic in the swap logic. Guardrail's pool manipulation and balance anomaly guards detect this pattern by monitoring for abnormal price movements and liquidity changes within single transactions. **Silo Finance ($500K+) — June 2025** An unreleased leverage feature was exploited during testing. Even test deployments need monitoring—Guardrail's event and function guards would have detected unexpected interactions with the vulnerable contracts. ## 2024 Highlights **Radiant Capital ($50M) — October 2024** Not a code bug—compromised developer machines displayed fake transaction data to multisig signers. Guardrail's multisig threshold guard would have flagged the signing requirements, and admin event monitoring would have detected the ownership change before fund drainage. **Penpie ($27M) — September 2024** Reentrancy attack on the reward calculation logic. The attacker used fake Pendle market contracts to manipulate deposits mid-transaction. Guardrail's reentrancy guard and function sequence validation detect this pattern. **Ronin Bridge ($12M) — August 2024** A proxy upgrade without initialization allowed anyone to withdraw tokens. Guardrail's proxy uninitialized upgrade guard specifically detects when upgrades occur without accompanying initialization calls. ## Attack Pattern Coverage | Pattern | Guardrail Detection | | ----------------------- | ------------------------------------------ | | Reentrancy | Reentrancy Guard, Function Sequence Guard | | Flash Loan Manipulation | Flash Loan Guard, Pool Manipulation Guard | | Oracle Attacks | Price Deviation Guard, Oracle Health Guard | | Governance Exploits | Multisig Threshold, Admin Event Guards | | Uninitialized Proxies | Proxy Upgrade Guard | | Private Key Compromise | Balance Drop Guard, Admin Change Detection | *** # Guard Catalog Guards are configurable security checks that run on blockchain transactions.

[Get in touch →](https://www.guardrail.ai/get-started) {% endhint %} ## Custom Guards Can't find what you need? Our security team builds custom guards for your specific architecture. We also support DIY guards where you write Python code to implement custom detection logic. [Contact us for custom monitoring →](https://www.guardrail.ai/get-started) For guard configuration and setup, see [App Documentation →](https://docs.guardrail.ai/app/guards) *** # Runtime Security Detect attacks that happen during transaction execution. ## Reentrancy Detection Monitors when contracts or functions are called recursively before initial execution completes. Available at both contract-level and function-level granularity for precise coverage of withdraw, transfer, and critical state-changing functions. **Related Incidents:** Penpie ($27M), Sumer Money, Minterest Finance ## Flash Loan Monitoring Detects transactions that combine flash loan operations with calls to critical contracts or significant fund outflows. Catches manipulation attempts, price oracle attacks, and complex DeFi exploits using uncollateralized instant loans. **Related Incidents:** Multiple oracle manipulation attacks ## Function Sequence Validation Alerts if functions occur in unexpected sequences. Use whitelist mode to enforce atomic execution or blacklist mode to block dangerous patterns. **Related Incidents:** Sonne Finance, DeltaPrime, UwU Lend ## External Call Protection Enforces strict rules on which functions can be called immediately after specific contract interactions. Whitelist or blacklist specific call patterns to detect unauthorized interactions. **Related Incidents:** Spectra, Dough Finance, LI.FI ## Illogical Function Loops Detects suspicious function call patterns that shouldn't occur in the same transaction, like adding and removing liquidity atomically, or opening and liquidating a position in a single tx. **Related Incidents:** Vyper exploit, Zunami ## Sandwich Attack Detection Monitors for coordinated sandwich attacks, front-running, and back-running patterns. Identifies MEV bots, transaction reordering attacks, and mempool exploitation that steal value through slippage manipulation. ## Delegatecall Monitoring Monitors delegatecalls to unauthorized functions that could compromise contract security. Detects malicious delegatecall attacks, unauthorized proxy calls, implementation manipulation, and access control bypasses. ## High Gas Detection Identifies transactions with unusually high gas consumption that may indicate attack attempts, DoS attempts, infinite loops, reentrancy exploits, or computational abuse. ## Trace Call Frequency Detects potential exploits by identifying excessive function call frequencies within single transactions. {% hint style="info" %} **Need a custom guard?** Our security team can build guards tailored to your protocol's specific architecture. [Get in touch →](https://www.guardrail.ai/get-started) {% endhint %} *** # Governance & Access Monitor administrative actions, access control changes, and multisig operations. ## Multisig & Safe Monitoring Comprehensive Gnosis Safe monitoring covering signature thresholds, ownership changes, module additions, guard configuration changes, transaction executions, and signature approvals. Alerts when required signer thresholds drop below safe levels or unauthorized changes are made. **Related Incidents:** Radiant Capital ($50M) ## Admin Event Monitoring Tracks critical contract events: ownership transfers, role grants, parameter changes, pauses, and upgrades. Configure which events to monitor and set alert thresholds for immediate visibility into administrative actions. ## Function Call Restrictions Validates that restricted addresses can only call pre-approved functions. Detects privilege escalation and unauthorized access to admin operations through function allowlisting. ## Proxy Upgrade Monitoring Validates contract upgrades are properly initialized after deployment. Detects uninitialized proxy vulnerabilities, storage slot corruption, and unauthorized implementation changes. **Related Incidents:** Nomad ($190M), Ronin Bridge ($12M), LI.FI ($10M) ## Storage Slot Integrity Monitors critical storage slots — especially proxy implementation addresses — for unauthorized changes. Detects storage manipulation attacks, proxy hijacking, and storage collision exploits. {% hint style="info" %} **Need a custom guard?** Our security team can build guards tailored to your protocol's specific architecture.

A Slack notification showing a guard alert with a successful response action that paused a contract

A guard alert triggers an automatic on-chain response - here, calling pause() on a contract - with the result delivered to your alert channels.

## Capabilities * **Automated On-Chain Response** - Configure smart contract function calls that fire automatically when a guard alerts. Pause contracts, revoke permissions, or trigger any on-chain action your protocol needs. * **Dedicated Wallets** - Each response action gets a dedicated, securely encrypted wallet used only for that specific action. Wallets are single-purpose by design. * **Gas Management** - Gas for reasonably-sized response action transactions is funded and managed by Guardrail. No need to maintain ETH balances in action wallet. * **Simulation** - Test response actions before going live with dry-run simulation to verify permissions and function calls are configured correctly. * **Cooldown Controls** - Configurable cooldown periods prevent redundant on-chain calls when a guard alerts repeatedly. * **Integrated Notifications** - Response action results are included in your existing alert channel notifications (Slack, Discord, Telegram, etc.) with transaction hash, status, and gas usage. * **Transaction History** - Full audit log of every response action execution with status, timestamps, and on-chain transaction details.
