What Is Tenderly AI and Why Does It Matter?
Tenderly AI solves a critical problem for blockchain teams: visibility into production smart contracts. Unlike local testing environments, Tenderly connects to live chains and provides real-time transaction tracing, error decoding, and alerting. For teams already using Hardhat or Foundry for local development, Tenderly fills the gap between pre-deployment testing and post-deployment monitoring. The platform also integrates with Web3.js and ethers.js, making it a natural addition to existing workflows. For Web3 infrastructure teams, the strategic value lies in reducing mean time to resolution (MTTR) for on-chain incidents.
Who Should Use Tenderly AI?
- Blockchain engineering leads: Debug production contract failures with full transaction context instead of raw RPC logs.
- DevOps for Web3: Set up automated alerts for failed transactions, gas spikes, and contract interactions without building custom monitoring.
- Smart contract auditors: Simulate transactions and replay mainnet states to verify vulnerabilities in a sandboxed environment.
- DeFi protocol operators: Monitor critical contract functions and receive real-time notifications when user transactions revert.
Professional reality: Tenderly is not a replacement for local testing frameworks — it is a production monitoring and debugging layer that adds cost for teams with simple, low-volume contracts.
Tenderly AI Features That Drive Results
Production transaction tracing with full call stack
When a user transaction fails, Tenderly decodes the entire call stack — including internal calls, state changes, and gas usage — into a readable format. Engineers can inspect exactly which line of Solidity caused the revert without parsing raw RPC responses.
Business outcome: Reduce debugging time from hours to minutes for production contract failures.
Real-time contract alerts and dashboards
Teams configure alerts for specific contract events — failed transactions, gas price thresholds, or interaction volume spikes. Dashboards aggregate on-chain activity across all deployed contracts in one view.
Business outcome: Proactive incident detection without building custom monitoring infrastructure.
Fork and simulate mainnet state locally
Tenderly allows teams to fork any block on supported chains and simulate transactions against that exact state. This is useful for testing contract upgrades, simulating user flows, or reproducing reported bugs in a production-like environment.
Business outcome: Safer contract upgrades and faster bug reproduction by testing against real on-chain data.
Multi-channel alerting with custom logic
Alerts can trigger via Slack, Discord, Telegram, email, or webhook. Teams define conditions using a simple expression language — for example, alert when a specific function reverts more than 5 times in 10 minutes.
Business outcome: Immediate notification of critical contract issues without manual log checking.
Programmatic access to transaction data
Tenderly exposes a REST API for querying transaction simulations, alert history, and contract metadata. Teams can integrate Tenderly data into internal dashboards, CI/CD pipelines, or custom tooling.
Business outcome: Embed Tenderly data into existing operational workflows and automate incident response.
Audit logs and team access controls
Enterprise plans include audit logs of all actions taken within the Tenderly dashboard, plus role-based access controls for team members. This supports compliance requirements for regulated DeFi protocols.
Business outcome: Meet audit and compliance requirements for team actions on production monitoring systems.
Tenderly AI Pricing in 2026
Tenderly offers a free tier with limited transaction simulations and basic monitoring — suitable for individual developers testing contracts. The Team plan at $99/month unlocks advanced debugging, custom alerts, and multi-chain support. Enterprise pricing is custom and includes dedicated support, audit logs, and higher throughput limits. Annual billing reduces the monthly cost by approximately 20%. For teams deploying to multiple chains with high transaction volumes, the Team or Enterprise tier is necessary.
| Plan | Price | What You Get |
|---|---|---|
| Free | $0/month | Limited simulations, basic monitoring, single user. |
| Team Best Value | $99/month | Advanced debugging, custom alerts, multi-chain, 5 users. |
| Enterprise | Custom | Unlimited simulations, audit logs, dedicated support, custom throughput. |

Where Tenderly AI Is Strong / Where It Needs Care
- Production debugging depthFull call stack decoding with state diff makes Tenderly the best tool for diagnosing real contract failures.
- Multi-chain coverageSupports Ethereum, Polygon, Arbitrum, Optimism, and other major EVM chains from a single dashboard.
- Alert customizationExpression-based alert logic allows teams to define precise conditions without writing custom bots.
- Simulation accuracyForking mainnet state produces simulation results that closely match real transaction outcomes.
- Cost at scaleHigh transaction volumes or frequent simulations can push costs significantly beyond the base plan.
- Not a development frameworkTenderly does not replace local testing with Hardhat or Foundry — it is a monitoring layer, not a development environment.
- Learning curve for alertsThe alert expression language requires some initial learning for teams unfamiliar with event-driven monitoring.
- Professional RealityTenderly delivers the most value for teams with multiple production contracts on several chains — a single contract on one chain may not justify the cost.
Real-World Use Cases
DeFi protocol incident response
When a lending protocol experiences a failed liquidation transaction, the engineering team uses Tenderly to trace the exact call path and identify the root cause within minutes instead of hours.
NFT marketplace monitoring
An NFT marketplace team configures alerts for failed mint transactions and unusual gas price spikes, enabling proactive responses to network congestion or contract issues.
Smart contract upgrade testing
Before deploying a proxy upgrade, a team simulates the upgrade transaction against the current mainnet state using Tenderly to verify storage slot compatibility and function behavior.
Cross-chain bridge debugging
A cross-chain bridge team uses Tenderly to monitor transactions on both source and destination chains, correlating events to identify failed relay attempts or mismatched state.
How to Get Started With Tenderly AI
Create a free Tenderly account and connect your wallet or API key.
Deploy or import your existing smart contract by providing its address and ABI.
Set up your first alert — for example, notify your team Slack when any transaction to your contract reverts.
Use the simulation tool to replay a recent failed transaction and inspect the full call stack and state changes.
Is Tenderly AI Worth It in 2026?
For blockchain teams managing multiple production contracts across several chains, Tenderly is a worthwhile investment that directly reduces debugging time and incident response effort. The platform's simulation accuracy and alert customization are its strongest assets. The main limitation is cost — teams with simple, single-chain deployments may find the free tier sufficient but the paid plans expensive relative to their needs. In 2026, Tenderly is best suited for DeFi protocols, NFT marketplaces, and cross-chain infrastructure teams that cannot afford hours of downtime debugging production failures. For those teams, the platform pays for itself after the first incident it helps resolve quickly.

Tenderly AI vs Hardhat
Hardhat is the dominant local development framework for Solidity, providing testing, compilation, and debugging in a local environment. Tenderly focuses on production monitoring and simulation against live chain state, while Hardhat excels at pre-deployment testing. Teams often use both: Hardhat for local development and Tenderly for production visibility.
Choose Tenderly AI if: You need real-time production monitoring and full transaction tracing on live chains. Choose Hardhat if: Your primary need is local contract testing and deployment scripting without production monitoring.
Tenderly AI vs OpenZeppelin Defender
OpenZeppelin Defender offers admin panels, automated actions, and monitoring for smart contracts, with a stronger focus on access control and governance. Tenderly provides deeper debugging capabilities and more flexible alerting, while Defender excels at contract administration and automated responses.
Choose Tenderly AI if: Your priority is deep transaction debugging and simulation across multiple chains. Choose OpenZeppelin Defender if: You need automated contract administration, relayers, and governance-focused tooling.
