Mainnet data replica
Network customization

Reusable network templates
10 pre-loaded test accounts
Millisecond TX execution

Supported across
30+ networks

Build and test your dapps using production data. Execute transactions and deploy your code on an exact replica of the latest state of your selected network.

Explore supported networks

DevNets toolset

Harness the power of Tenderly's advanced development, testing, and debugging tools right in your local environment.

Visual Debugger

Catch and fix bugs in your contracts and understand failing transactions at a glance.

Annotations

Leave comments on any line of code and get your entire team involved in debugging.

Transaction Simulator

Dry-run transactions and edit the contract source to ensure your fixes work as intended.

Easy integration with the frameworks you already use & love

Use these resources to learn how to integrate DevNets into your existing Hardhat, Truffle, and Foundry projects.

Hardhat

Unlock access to our Debugger, Simulator, TX Trace, and many other features when developing locally with Hardhat.

GET STARTED

Truffle

Deploy contracts and run transactions from your Truffle projects on a private network fork that comes with its own execution engine.

GET STARTED

Foundry

Remove local node management from your dev and testing workflows in Foundry. Run tests and iterate faster with DevNets.

Copy the RPC URL

DevNets + Hardhat quickstart

Integrating DevNets into your Hardhat project is straightforward. Simply make a few edits to your Hardhat config file: add a new Tenderly networks object and insert the auto-generated RPC URL.

Create DevNet templates faster using YAML

If you need more customization options when creating DevNet templates, use the YAML template editor. With YAML templates, you can override balances on any of the accounts on your fork, modify storage, change the balances of addresses for specific ERC-20 contracts, and more.

Learn how to create YAML templates

Spawn a DevNet using Tenderly CLI

Automate DevNet spawning using the spawn-rpc CLI command, which will instantly spin up a DevNet environment and inject its RPC URL directly into your Hardhat config file.

Install Tenderly CLI

Spawn DevNets using Bash and JS

Unlimited faucet

All accounts on your network fork are unlocked, enabling you to easily adjust the balance of any contract or wallet. The unlimited faucet is accessible from the Dashboard, or you can use the Tenderly Faucet app. Alternatively, you can use custom Tenderly RPC methods to set a specific balance on an account or add more test ETH.

Contract verification on DevNets

Tenderly uses the contract source code to enable the full potential of our Debugger and other tools. To take advantage of these and other features, we recommend that you verify your smart contracts.
