Virtual TestNets Quickstart

Follow this guide to learn how to spin up a Virtual TestNet and start interacting with it.

Configure your Virtual TestNet

From the Dashboard, go to Virtual TestNets and click Create Virtual TestNet. Fill in the settings below:

Parent network and name: Choose which network you want to fork from the 42+ supported networks and give it a unique name (e.g., Virtual Mainnet).

Chain ID: Specify a custom value such as 73571 or use the parent network’s original chain ID. It’s recommended to set a unique chain ID to prevent transaction replay attacks, and avoid issues when adding the Virtual TestNet to wallets.

Public Explorer: Leave disabled or enable to allow public transaction viewing. If enabled, set the contract verification visibility option to control whether or not smart contracts’ code is visible publicly.

State sync: Activate to keep your Virtual TestNet updated in real-time with the parent network. Learn more about how state sync works.

Click Create.

Add TestNet to Metamask

Access your TestNet and click Add to Wallet to add the TestNet as a chain in Metamask. Follow Metamask’s instructions to change the network. Once confirmed, you can send and receive transactions on your TestNet through Metamask.

Fund accounts

Every TestNet has an unlimited faucet that allows you to top up or set a new balance for any account on the TestNet instantly.

From the Dashboard

  • Navigate to Faucet
  • Input your address (0xBd8DaA414Fda8a8A129F7035e7496759C5aF8570) and the amount you wish to add (e.g., 1000) in ETH (not wei).
  • Click Fund

Using RPC

Copy the Testnet RPC link and call the tenderly_setBalance method to set a new balance specified in wei in hexadecimal form.

-H "Content-Type: application/json" \
-d '{
    "jsonrpc": "2.0",
    "method": "tenderly_setBalance",
    "params": [["0xE58b9ee93700A616b50509C8292977FA7a0f8ce1"], "0xDE0B6B3A7640000"],
