About
Tenderly is a full-stack Web3 infrastructure platform purpose-built for professional blockchain developers and dapp teams. It consolidates the entire development lifecycle into a single, cohesive environment—eliminating the need to juggle multiple fragmented tools. At its core, Tenderly's Virtual TestNets replace traditional local nodes and public testnets with customizable, zero-setup development environments that sync with production chain state. Developers can fork any EVM chain within milliseconds and work with real mainnet data without writing a single line of boilerplate configuration. The built-in Explorer provides total observability into contracts, wallets, and transactions, complete with full stack traces and human-readable error messages. The platform's high-performance Node RPC goes beyond standard node infrastructure, offering advanced APIs and global traffic distribution for production-grade applications. A Transaction Simulator lets teams preview transaction outcomes before committing on-chain, reducing costly mistakes. Integrated debugging tools enable granular smart contract analysis and gas optimization. For DevOps workflows, Tenderly integrates natively with Hardhat and Foundry, supports CI/CD pipelines with managed environments, and provides real-time monitoring and automated alerting for on-chain events. Teams benefit from collaborative tooling, shared infrastructure, and built-in contract verification. Tenderly supports all major EVM-compatible chains, making it an ideal choice for Web3 startups, enterprise blockchain teams, and solo developers who need production-grade infrastructure without the overhead.
Key Features
- Virtual TestNets: Customizable, zero-setup development environments that replace local nodes and public testnets, with full mainnet state syncing and multi-chain fork support in milliseconds.
- High-Performance Node RPC: Scalable and extensible node infrastructure with advanced APIs, global RPC traffic distribution, and full customization for production-grade dapp performance.
- Transaction Simulator: Preview transaction outcomes before submitting on-chain, reducing costly errors and enabling safer smart contract interactions across any EVM chain.
- Granular Debugging Tools: Full stack trace analysis, human-readable error messages, gas optimization insights, and built-in contract verification with source code and ABI management.
- Real-Time Monitoring & Alerts: Automated on-chain event monitoring with customizable alerting, giving teams instant visibility into contract activity and production infrastructure health.
Use Cases
- Smart contract developers using Hardhat or Foundry who need mainnet-accurate test environments without managing local nodes or dealing with flaky public testnets.
- Web3 engineering teams running CI/CD pipelines who need managed, ephemeral test environments that spin up quickly and integrate with automated build and release workflows.
- DApp product teams that need real-time monitoring and alerting on deployed smart contracts to detect anomalies, exploits, or unexpected behavior in production.
- Blockchain developers debugging complex multi-contract interactions who need full stack traces, decoded transaction data, and human-readable error messages to identify root causes quickly.
- Web3 startups and enterprises building cross-chain applications who need a single infrastructure platform that works consistently across all major EVM-compatible networks.
Pros
- End-to-End Web3 Toolchain: Covers the entire dapp lifecycle from local development and testing to CI/CD integration, production deployment, and monitoring—eliminating tool sprawl.
- Mainnet Data in Dev Environments: Virtual TestNets sync with live chain state, allowing developers to test against real data without expensive on-chain transactions or brittle mocked environments.
- Broad EVM Chain Support: Natively supports all major EVM-compatible chains, so teams can move their entire stack across networks without rebuilding workflows.
- Team Collaboration Built-In: Shared infrastructure, collaborative debugging tools, and built-in explorers make it easy for entire engineering teams to work together on the same environment.
Cons
- Web3-Specific Scope: Tenderly is exclusively designed for EVM-compatible blockchain development, offering no utility for teams building outside the Web3 ecosystem.
- Learning Curve for New Web3 Devs: The breadth of features—Virtual TestNets, RPC configuration, debugging tools—can be overwhelming for developers new to blockchain development.
- Pricing Scales with Usage: While a free tier is available, enterprise-grade features and higher usage limits require contacting sales, with costs potentially rising significantly for large teams.
Frequently Asked Questions
What are Virtual TestNets and how do they differ from public testnets?
Virtual TestNets are fully customizable, zero-setup development environments that replace both local nodes and public testnets. Unlike public testnets, they sync with live mainnet data, can fork any EVM chain in milliseconds, support unlimited token faucets, and include built-in explorers and debugging tools—all without requiring code changes to your project.
Which blockchain networks does Tenderly support?
Tenderly supports all major EVM-compatible chains. You can fork, test, simulate, and deploy across these networks using a unified infrastructure stack, with native multichain support built into Virtual TestNets and Node RPC.
Can Tenderly integrate with existing development frameworks?
Yes. Tenderly integrates natively with popular Web3 development frameworks like Hardhat and Foundry, as well as CI/CD pipelines. You only need to update the RPC endpoint in your existing workflows—no code changes required.
Is Tenderly free to use?
Tenderly offers a free tier for individual developers to get started. For teams needing collaborative features, higher usage limits, or enterprise-grade infrastructure, paid plans are available—contact the Tenderly team for pricing details.
How does the Transaction Simulator help developers?
The Transaction Simulator lets you preview the exact outcome of a transaction—including state changes, emitted events, and gas costs—before it is submitted on-chain. This helps catch bugs, prevent costly mistakes, and validate contract logic safely.
