This crowdsourced intelligence model provides broad coverage and rapid response to novel threats like flash loan attacks or governance exploits. For example, Forta bots flagged the $190M Nomad bridge exploit within seconds, enabling some users to act before funds were fully drained. Its strength is in continuous, automated monitoring across multiple chains like Ethereum, Polygon, and Arbitrum.
Forta vs Tenderly: Real-time Threat Detection
Introduction: Two Philosophies of On-Chain Security
Forta and Tenderly represent distinct architectural approaches to securing on-chain operations, from real-time threat detection to post-mortem analysis.
Tenderly takes a different approach by providing a centralized, developer-focused platform for simulation and debugging. Its core strength is deep, forensic analysis—allowing teams to replay transactions, set up custom alerts based on precise contract state changes, and simulate attacks before deployment. This results in a trade-off: unparalleled depth and control for your specific protocol versus Forta's broad, network-wide threat intelligence. Tenderly's Web3 Actions and Gas Profiler are pivotal for pre-production security.
The key trade-off: If your priority is network-wide, real-time anomaly detection and you want to leverage collective intelligence against emerging threats, choose Forta. If you prioritize deep, customizable forensic analysis, pre-deployment simulation, and granular alerting on your specific smart contract logic, choose Tenderly. The former acts as a decentralized immune system; the latter is a powerful surgical toolkit for your engineering team.
TL;DR: Core Differentiators

With over 50,000 detection bots deployed, it excels at identifying novel threats like flash loan attacks or governance exploits across 40+ chains. This matters for protocols requiring censorship-resistant, community-driven security and broad coverage.
Forta: Protocol-Level Security Focus
Architected for smart contract risk and financial anomalies. Its core use cases are real-time exploit alerts, transaction simulation for threat detection, and compliance monitoring. This matters for DeFi protocols, DAOs, and auditors who need to protect TVL and respond to incidents in seconds.
Tenderly: Developer-Centric Debugging & Simulation
Provides deep, state-level transaction inspection and forking. Its Web3 Gateway and Simulation API enable teams to debug failed transactions, test complex scenarios, and monitor custom metrics. This matters for engineering teams building and maintaining dApps who prioritize development velocity and pre-deployment security.
Tenderly: Integrated DevEx Platform
Bundles monitoring with a full-stack development environment. Features like Gas Profiler, Alerting on custom formulas, and visual debuggers reduce tool sprawl. This matters for CTOs managing engineering budgets who want a single platform for development, testing, and production observability.

Forta vs Tenderly: Real-time Threat Detection
Key strengths and trade-offs for two leading on-chain monitoring platforms.
Forta: Decentralized Detection Network
Leverages a crowd-sourced network of over 40,000 detection bots run by independent node operators. This provides censorship resistance and diverse threat intelligence, making it ideal for protocols requiring unbiased, community-driven security like DAO treasuries or cross-chain bridges.
Tenderly: Integrated DevEx & Debugging
Unified platform combining monitoring, alerting, debugging, and forking. Provides visual transaction traces and state diffs that drastically reduce MTTR (Mean Time to Resolution). Best for engineering teams wanting an all-in-one observability suite without managing multiple tools.
Forta: Cons - Steeper Operational Overhead
Requires managing detection bot logic and staking FORT tokens to run nodes or subscribe to feeds. Less "out-of-the-box" for simple monitoring, adding complexity for teams that just need uptime/downtime alerts.
Tenderly: Cons - Centralized Service Provider
A managed, proprietary service that introduces vendor lock-in and a central point of failure. Not suitable for protocols with strict decentralization requirements or those needing guarantees against censorship of security alerts.
Tenderly: Pros and Cons
Key strengths and trade-offs for two leading on-chain monitoring platforms at a glance.
Tenderly Pro: Integrated Development & Monitoring
Specific advantage: Combines debugging, simulation, and alerting in one platform. This matters for teams that want to unify their devops lifecycle from testing to production monitoring, reducing context switching between tools like Hardhat and separate alerting dashboards.
Tenderly Pro: Advanced Transaction Simulation
Specific advantage: Offers a state-aware simulation engine that can predict transaction outcomes before submission. This matters for preventing failed transactions and optimizing gas costs in real-time, a critical feature for high-frequency trading bots or complex DeFi interactions.
Tenderly Con: Centralized Alerting Model
Specific trade-off: Alert creation and processing are managed by Tenderly's infrastructure. This matters for teams requiring decentralized or trust-minimized security where the detection logic itself should be transparent and verifiable on-chain, unlike Forta's decentralized bot network.
Tenderly Con: Limited Custom Detection Scope
Specific trade-off: Primarily focused on transaction and event-based alerts for your own contracts. This matters for protocol-wide security monitoring where you need to detect novel threats (e.g., governance attacks, oracle manipulation) across the entire ecosystem, not just your deployment.
Forta Pro: Decentralized Detection Network
Specific advantage: Leverages a permissionless network of node operators running detection bots. This matters for achieving censorship-resistant security and diverse threat intelligence, as seen in its use by major protocols like Lido and Aave for real-time exploit detection.
Forta Pro: Ecosystem-Wide Threat Intelligence
Specific advantage: Bots monitor public mempool and on-chain activity across all contracts, not just yours. This matters for early warning of correlated risks and emerging attack patterns (e.g., identifying a malicious contract that is targeting multiple protocols).
Decision Framework: When to Choose Which
Forta for Protocol Security
Verdict: The specialized, on-chain detection network. Strengths: Forta excels at real-time, autonomous threat detection for live smart contracts. Its decentralized network of detection bots monitors for exploits, governance attacks, and anomalous transaction patterns (e.g., flash loan attacks, oracle manipulation). Key metrics like detection time and false positive rate are critical. It integrates directly with security response systems like OpenZeppelin Defender for automated pausing or upgrading. Use Case: A DeFi protocol like Aave or Compound uses Forta to monitor its lending pools 24/7, with bots scanning for sudden, large withdrawals or abnormal price feed deviations, triggering immediate alerts to the security team.
Tenderly for Protocol Security
Verdict: The forensic analysis and simulation powerhouse. Strengths: Tenderly is unmatched for post-mortem analysis and pre-deployment simulation. Its deep transaction tracing, state diffs, and gas profiling let you dissect an incident after it occurs. The simulation feature allows you to replay attacks or test security patches against forked mainnet state. Use Case: After a suspicious event, a protocol's security team uses Tenderly to trace the attacker's contract calls, identify the exploited vulnerability, and simulate a fix on a forked chain before deploying the patch.
Final Verdict and Strategic Recommendation
Choosing between Forta and Tenderly hinges on whether your primary need is specialized, decentralized security monitoring or integrated, developer-centric observability.
Forta excels at decentralized, real-time threat detection because of its network of node operators running detection bots on-chain. This creates a robust, censorship-resistant security layer. For example, its bots have flagged over $1B in prevented exploits across protocols like Aave and Compound, with a detection latency measured in seconds. Its strength is in providing a specialized, protocol-agnostic security feed that integrates into automated response systems via its API or smart contract agents.
Tenderly takes a different approach by bundling real-time monitoring within a comprehensive Web3 development platform. This results in a powerful, integrated workflow where you can detect anomalies, debug them in a simulated environment, and deploy fixes—all in one interface. The trade-off is a more centralized, developer-focused toolchain optimized for speed and iteration over decentralized security guarantees. Its Alerting feature is powerful for tracking custom on-chain conditions but is part of a broader suite including Debugger and Simulator.
The key trade-off: If your priority is decentralized security operations and composable threat intelligence for a live protocol, choose Forta. Its specialized agent network and security-focused data feeds are built for this. If you prioritize developer velocity and integrated observability during development and maintenance, choose Tenderly. Its seamless workflow from alert to debug to simulation is unparalleled for engineering teams building and iterating quickly.
