📣 General Info

Tenderly is an all-in-one Web3 development platform that accelerates smart contract development and provides a fully integrated developer experience. It combines in-depth debugging tools with observability and blockchain infrastructure.

Web3 developers can use the Tenderly platform to build, test, monitor, and operate smart contracts in one place. The platform covers every aspect of smart contract development, from inception and prototyping to production monitoring and on-chain usage.

All Tenderly tools are fully integrated, eliminate development fragmentation, and ensure a unified experience for Web3 developers. They fall into three main categories:

  • Development
  • Observability
  • Infrastructure 3.0

Learn more about each category and how you can benefit from Tenderly tools.

🚀 Infrastructure 3.0

Tenderly Infrastructure 3.0 brings together integral building blocks for smart contract integration and blockchain interaction. This category gives you fast and easy blockchain access with Tenderly Node. It also includes Tenderly Web3 Actions that give you more control over your contracts’ on-chain usage. Finally, Tenderly APIs are also part of the core infrastructure, enabling workflow automation and easy integration.

Tenderly Node

Tenderly Node is a production node that offers reliable, fast, and consistent access to the blockchain. It supports the standard JSON-RPC interface and custom-built endpoints thanks to its unique architecture.

Use the Tenderly node to:

  • Perform read-heavy workloads up to eight times faster.

  • Read, stream, and analyze blockchain data with 100% consistency.

  • Run tx simulations before sending them on-chain using a single RPC URL.

  • Build your own custom node abstraction by writing your own RPC methods using Node Extensions.

  • Eliminate the node infrastructure overhead and focus on building your dapps.

Simulation API

Tenderly Simulation API enables you to run transaction simulations programmatically. Integrate Transaction Simulator into your workflow and fork any Tenderly-supported network. This way, you can automate your development process and boost team efficiency. For instance, you can use Simulation API to integrate a testing environment and run batched simulations for a more efficient testing process.

Then, you can stage a QA environment for your dapp so you can complete end-to-end testing before deploying it on-chain. To enable your users to try out your dapp for free, just use Simulation API to run your dapp in demo mode.

Once your dapp is live on-chain, you can use Simulation API to improve its UX. Simply allow your users to dry-run transactions and execute them with confidence.

Integrate with Simulation API to:

  • Expose Transaction Simulator to your dapp users and enable them to validate transactions directly from your dapp.

  • Deliver more value faster and eliminate guesswork and anxiety for your users.

  • Simulate DAO governance proposals to generate reports and preview their effects.

  • Automate your development, testing, and troubleshooting processes to eliminate manual work for your team.

Tenderly Web3 Actions

Tenderly Web3 Actions are a low-setup, low-maintenance, and low-cost automated serverless backend for your dapps. They can serve as programmable hooks for relevant on-chain or off-chain events.

A customizable Tenderly Web3 Action enables you to:

  • Build active monitoring and automate custom code responses to on-chain or off-chain events.

  • Combine Web3 Actions with Alerting to create new alert-response patterns and stay on top of relevant on-chain changes.

  • Connect your smart contracts with on-chain events, dapp frontends, APIs, and other services.

  • Improve dapp UX and interactivity by gathering and sharing in-depth information through notifications.

Tenderly’s development tools enable you to speed up and simplify smart contract development. They provide the necessary support for debugging, testing, and optimizing your smart contracts. You can use them to build smart contracts on more than 20 Tenderly-supported networks.

Sandbox

Tenderly Sandbox is a sharable zero-setup prototyping environment for Solidity developers. As an in-browser editor, it helps you eliminate the lengthy setup part of Web3 development. Sandbox also combines Solidity and JavaScript, so it’s an easy entry point for Web3 newcomers.

Set up your own Tenderly Sandbox to:

  • Deploy and run your smart contracts on a Tenderly Fork almost instantly without using a testnet.

  • Get extensive data on smart contract execution with a detailed output, list of executed transactions, and other information available in the Tenderly Dashboard.

  • Debug executed transactions quickly and easily by opening Tenderly Debugger directly from your Sandbox environment.

  • Share your work with other engineers, demonstrate protocol integration, and clone others’ work to test your own solutions.

Tenderly Debugger

Tenderly Debugger is a user-friendly tool for streamlining your debugging process during development and when troubleshooting transactions in production. This tool allows you to identify the exact lines of code causing a bug. It also eliminates the need for manual decoding, speeding up the entire process.

With Tenderly Debugger, you can:

  • Inspect, troubleshoot, and fix exact lines of code to speed up and simplify debugging.

  • Filter internal and external calls to identify suspicious activity in the event of hacks and exploits.

  • Trace transaction execution and use filters such as opcode, state variables, and functions for in-depth information.

  • Use Evaluate Expression as a part of Advanced Debugger to evaluate both simple and complex transaction expressions.

  • Use State Inspector to analyze decoded state changes and state variables of your smart contract in a granular view to understand how it behaves in production.

  • Use Debugger Chrome Extension to open transactions in Tenderly Debugger directly from your browser.

Gas Profiler

Gas Profiler gives you an in-depth insight into how your smart contract uses gas per function call. It enables you to analyze executed transactions or optimize your code while still in development.

To reduce smart contract gas consumption, use Gas Profiler to:

  • Get a granular gas usage breakdown and analyze how each function call spends gas.

  • Identify gas-intensive lines of code that you can further optimize using other Tenderly tools.

  • Apply some of the best coding practices to reduce the gas cost of your transactions before sending them on-chain.

Transaction Simulator

Transaction Simulator allows you to preview transactions directly from the Tenderly Dashboard before sending them on-chain. You can use this tool to run simulations using the most recent or historical blockchain data. It enables you to play out transaction outcomes, minimize the risk of errors, and eliminate unnecessary costs.

You can use this feature to simulate transaction execution with updated contract source code or different parameters, including tx indexes, block number, value, gas, and addresses.

By simulating transactions, you can:

  • Try out your smart contracts during development and identify potential issues early on, without deploying to a testnet.

  • Test and validate smart contract bug fixes or upgrades to ensure code correctness both during development and in production.

  • Replay failed transactions to identify the cause of a problem and gain a deeper understanding of their execution.

  • Simulate the expected outcome of pending transactions and optimize gas usage for all your transactions.
