Virtual TestNets Quickstart

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.
