# Hardhat

## Using Hardhat for StratoVM Development

Hardhat is recognised for being flexible, extensible and fast in the Ethereum smart contract development.

### Configuring Hardhat for StratoVM <a href="#configuring-hardhat-for-superseed" id="configuring-hardhat-for-superseed"></a>

To prepare Hardhat for deployment on the StratoVM networks, make the necessary adjustments to your `hardhat.config.ts`:

<pre class="language-javascript" data-overflow="wrap"><code class="lang-javascript">import { HardhatUserConfig } from "hardhat/config";
import "@nomiclabs/hardhat-ethers"; 
const config: HardhatUserConfig = {  networks: {       
/* For StratoVM Sepolia Testnet "stratovm-sepolia": 
{ url: "https://rpc.stratovm.io",  
<strong>    accounts: [process.env.PRIVATE_KEY as string],
</strong>    gasPrice: 1000000000,},    

// For local development environment    "stratovm-local": 
    {  url: "http://localhost:8545",      
    accounts: [process.env.PRIVATE_KEY as string],      
    gasPrice: 1000000000,    },  },  
    defaultNetwork: "stratovm-local",}; 
    
    export default config; */
</code></pre>

### Your Smart Contracts on Superseed Testnet <a href="#your-smart-contracts-on-superseed-testnet" id="your-smart-contracts-on-superseed-testnet"></a>

#### Deployment <a href="#deployment" id="deployment"></a>

Use Hardhat's deployment scripts, specifying the network:

```javascript
npx hardhat run scripts/deploy.ts --network stratovm-sepolia
```

#### Verification <a href="#verification" id="verification"></a>

After deploying, verify your smart contract using Hardhat's built-in verification tool:

{% code overflow="wrap" %}

```javascript
npx hardhat verify --network stratovm-sepolia DEPLOYED_CONTRACT_ADDRESS "Constructor argument 1"
```

{% endcode %}

💬

Remember to replace `DEPLOYED_CONTRACT_ADDRESS` and `"Constructor argument 1"` with the actual address of your deployed contract and any necessary constructor parameters.

{% hint style="info" %}
The provided configurations and commands are aimed at offering a simple start-up process for developers working with Hardhat on the StratoVM blockchain. Adjustments may be needed based on specific contract requirements or network preferences.
