Tenderly Dev Toolkit

About

Overview

Tenderly Dev Toolkit allows you to explore, analyze, and debug transactions directly from any block explorer.  

Add the extension to your browser and access Tenderly’s powerful development infrastructure and tools in just one click. Instantly open any transaction hash in Tenderly for granular insights in a human-readable format. Replay transaction execution, debug errors trace by trace, or run transactions in a new development environment for further testing and experimentation.

How to use Tenderly Dev Toolkit?

With Tenderly Dev Toolkit available in your browser, you can jump straight to on-chain exploration and debugging from any block explorer. You no longer need to switch context or manually copy-paste transaction hashes. In a single click, you can explore, analyze, and debug on-chain data using Tenderly’s Web3-native tools for complete observability, flexibility, and efficiency. 

Once you install the extension, the toolbar gives you instant access to Tenderly’s industry-recognized dev tools and functionalities directly from any block explorer: 

- Simulate: Replay transactions with updated parameters, inputs, and even contract code. Preview transaction execution and see the expected outcomes without sending transactions on-chain.

- Debug: Troubleshoot failed transactions with a trace-by-trace Debugger. Analyze human-readable error messages and identify the exact cause and line of an error. Then, quickly edit contract code to try out a fix directly in your browser.

- View trace: Examine the entire execution of a transaction with a full stack trace and enriched transaction data. Dive into transaction opcodes, analyze gas usage, or highlight addresses with custom names and colors.  

- View state changes: Go through the state changes that happened during transaction execution, including old and new values. Understand what happened at a glance by analyzing events or variables in both decoded and raw format.

- View gas usage: Analyze how transactions use gas per individual function call. Get a granular breakdown of gas consumption during execution. Identify computationally intensive lines of code and optimize them to reduce gas usage.

- Run on VNet: Replay transaction execution on a new Virtual TestNet, a zero-setup development environment synced with the latest mainnet state. Run further tests and experiments with an unlimited faucet, unlocked public accounts, and custom RPC methods.

Speed up your on-chain exploration and debugging across EVM chains, L2s, and rollups with powerful Tenderly tools at your fingertips.
