Overview
Tenderly is a purpose‑built, full‑stack infrastructure platform for Web3 developers and teams. It combines a customizable Node RPC, Virtual TestNets, and a Developer Explorer into a single environment that spans the entire dapp lifecycle—from local development and CI/CD to staging and on‑chain production. The platform prioritizes observability, collaboration, and simulation, allowing engineers to reproduce mainnet state, simulate transactions safely, and debug complex smart contract behavior with human‑readable detail.
Core Capabilities
-
Virtual TestNets: Replace public testnets or local nodes with zero‑setup environments that can fork mainnet state, sync ongoing state, and provide unlimited faucets and fully configurable testnet parameters. These environments include private and public explorers and enable teams to iterate faster without changing application code—just swap the RPC endpoint.
-
Developer Explorer: A Web3‑native explorer that surfaces decoded transaction data, detailed error & stack traces, step‑by‑step TX details, and a powerful debugger. The explorer makes on‑chain behavior accessible by showing emitted events, balance and state changes, and human‑readable messages that speed up root‑cause analysis.
-
Simulator: Accurately preview transaction outcomes without broadcasting them on‑chain. The Simulator lets developers manipulate inputs, contract code, and parameters to see the exact effects of a transaction in a risk‑free context, reducing costly mistakes and enabling safer UX for end users.
-
Customizable Node RPC: A production‑grade RPC layer that supports advanced APIs, global traffic handling, and the ability to extend node behavior by deploying custom logic inside the RPC. Teams can expose custom endpoints, react to on‑chain events, and integrate serverless or webhook‑driven backends.
-
Monitoring & Team Collaboration: Built‑in tooling for real‑time alerts, collaborative debugging, team workspaces, and CI/CD integration. Tenderly encourages shared workflows across frontend, backend, and smart contract engineers and supports staging and public testing to collect real usage feedback.
Additional Features and Workflow
Tenderly integrates with common tooling such as Hardhat and Foundry to enable local development with mainnet data. It supports multichain deployments across major EVM chains, L2s, and rollups, allowing teams to test and scale across environments without rearchitecting their stack. The platform also includes a gas profiler to analyze per‑function gas consumption and optimize expensive execution paths, and provides built‑in verification infrastructure for source code and ABI management.
Deployment and Production
Moving from dev to prod is simplified: teams can prototype and test on Virtual TestNets, run CI/CD pipelines against managed environments, and then switch the RPC to Tenderly’s production endpoints when ready. The Node RPC is designed for high availability, top performance, and global coverage to handle throughput spikes and production traffic patterns.
Why Choose Tenderly
Tenderly is recommended for teams building complex dapps that require deep visibility into EVM execution and repeatable, collaborative workflows. Its emphasis on simulation, decoded observability, and extensible RPC makes it especially valuable for security‑conscious projects and DeFi applications where precise behavior and gas efficiency matter. Case studies from organizations such as Uniswap, MakerDAO, and Yearn demonstrate real‑world value in debugging, simulation, and reliable node performance.
Getting Started
To begin, create an account, connect your tooling (Hardhat/Foundry), and spin up a Virtual TestNet or attach to the Node RPC. Use the Developer Explorer to debug transactions and the Simulator to validate changes before deployment. From there, scale into CI/CD and production with minimal changes—Tenderly is designed to integrate with existing development workflows and accelerate delivery while reducing on‑chain risk.
