# Testing with Hardhat

**Before you begin, please make sure to** [**create your StealthTest environment**](https://app.nameless.io/login) **and have access to the RPC URL and chain ID.** 

This document is intended to act as a quick start integration guide for new Hardhat projects. If you already have an established Hardhat project, skip to step 3.

For more information on Hardhat please access the documentation here: [Hardhat documentation](https://hardhat.org/hardhat-runner/docs/getting-started)

{% hint style="danger" %}
**We will never ask you for your private key, nor will it ever be required at *****any***** step in the process of creating a StealthTest environment.**
{% endhint %}

1. **Create a new Hardhat project.**

   1. `npm init -y`
   2. `npm install --save-dev hardhat`
   3. `npx hardhat`
   4. You will be provided with a default project containing: a smart contract, tests, and a deploy script.

2. **Compile your contracts**
   1. Contracts are located at `./contracts`
   2. `npx hardhat compile`
3. **Configure your Hardhat project for StealthTest**
   1. Within your `hardhat.config.js`
   2. Add an object called `networks`
   3. Inside that object, create an entry for `stealthtest`
   4. Add the `url`, `chainId`, and a list of `accounts` private keys you would like to use.
      1. **Note:** Each StealthTest environment comes with 5 pre-funded wallets, but please **never use these on mainnet**. You may also quickly fund your own wallet with our [Faucet](/features-and-fundamentals/faucet.md) but please **never share your private key with us or anyone you don't know.**&#x20;
   5. As an option, you can add `stealthtest` as your `defaultNetwork` so it will always be used.

:brain: **Example** `hardhat.config.js`&#x20;

```javascript
require("@nomicfoundation/hardhat-toolbox");

/** @type import('hardhat/config').HardhatUserConfig */
module.exports = {
  solidity: "0.8.18",
  defaultNetwork: "stealthtest",
  networks: {
    stealthtest: {
      url: "https://5937ec2d-1c79-41b8-a5d1-c288e0e2efc7.ethereum.staging-42.nameless.io",
      chainId: 148073,
      accounts: ["0xf5d82a795ec5c5751161334378841e7a765182a047ee071bdfb1184f67b78d76"],
    },
  },
};

```

4. **Deploy your contracts**
   1. `npx hardhat run scripts/deploy.js`
   2. `stealthtest` is your `defaultNetwork`, so your deployment(s) will be sent there

### And that's it! You're now testing in private using StealthTest! :muscle:
