Deploy Contracts on TestNets
Learn how to deploy smart contracts on your TestNet using Hardhat and Foundry.
Contracts deployed on a TestNet are called virtual contracts. You can find them in the Contracts section under the Virtual Contracts tab.
It’s recommended to verify your contracts as you deploy them, so you can use the Debugger, Gas Profiler, Simulator, and other tools.
Prerequisites
You have created a VirtualTestNet.
Deploy contracts using Foundry
You can deploy contracts to Virtual TestNets using Foundry’s forge create:
Run forge create
Pass the RPC URL to TENDERLY_VIRTUAL_TESTNET_RPC as the --rpc-url parameter. Then, run the forge create command.
PRIVATE_KEY=... # private key - if needed
TENDERLY_VIRTUAL_TESTNET_RPC=... # paste the RPC URL here
forge create Counter \
--rpc-url $TENDERLY_VIRTUAL_TESTNET_RPC \
--private-key $PRIVATE_KEYCheck the dashboard
In the Dashboard, go to Contracts and open Virtual Contracts tab, where you’ll find your contract.
Verify contracts

Deploy contracts using Hardhat
At the moment, the @tenderly/hardhat-tenderly plugin for Hardhat is compatible with Hardhat up to version 2.22.0.
Learn more about compatibility here.
To deploy a contract to your TestNet using Hardhat, you need to use the Tenderly-Hardhat plugin. Install the Tenderly-Hardhat plugin here and follow the steps below:
Add the RPC
Open the hardhat.config.ts and add virtualMainnet as a new network.
You also need to provide the RPC URL of your TestNet (networks.virtualMainnet.url) and the chain ID you’ve set during the creation of the TestNet.
Naming recommendation: prefix the name with virtual for easier distinction from other networks.
import { HardhatUserConfig } from "hardhat/config";
import "@nomicfoundation/hardhat-toolbox";
const config: HardhatUserConfig = {
solidity: "0.8.19",
networks:{
virtualMainnet: {
url: "RPC URL here",
chainId: 73571 // the Chain ID you selected during creation
}
}
};
export default config;Deploy
Run the deploy script with --network virtualMainnet.
npx hardhat run scripts/deploy.ts --network virtualMainnetCheck the dashboard
In the Dashboard, go to Contracts and open Virtual Contracts tab, where you’ll find your contract.
