To run the Hardhat network locally:

- Start the Hardhat network
- Hardhat comes with a built-in Ethereum network for development. Run the following command in your project's root directory to start it.
```shell
npx hardhat node
```
This command will start a local blockchain network and display a list of available accounts and private keys:

### Configure MetaMask

:::note[Install Metamask]
If you haven't already, you can use the [metamask-landing.rifos.org](https://metamask-landing.rifos.org/) tool to download/install Metamask, and add Rootstock custom network or follow the steps in [Configure Network and Token](/developers/blockchain-essentials/browser).

## Step 4: Connect Remix to Rootstock Testnet (Optional)
## Step 4: Interact with your deployed contract
1. Open Remix IDE
To interact with your deployed contract, you can create an interaction script using JavaScript/TypeScript and the [Ethers.js](https://docs.ethers.org/v5/) library.
- Go to [Remix IDE](https://remix.ethereum.org/) in your browser.
- Create a `interact.js` file in the `scripts` directory:
2. Connect MetaMask to Remix:
- In Remix, go to the **Deploy & run transactions** plugin.
- In the **Environment** dropdown, select **Injected Provider**.
- This will connect to MetaMask. Make sure MetaMask is on the `RSK Testnet` network that you configured earlier.
### Interact with the Deployed Contract on Remix
To interact with your deployed contract on Rootstock network:
- Load Your Deployed Contract
- Import the `myToken.sol` file into remix and compile.
```
touch scripts/interact.js
```
![Import Solidity File and Compile](/img/guides/quickstart/hardhat/compile-contract-remix.png)
- Paste the following code in the `interact.js` file:
- Once compiled, you should see the checkmark and solidiity file loaded into Remix.
```js
const hre = require("hardhat");
async function main() {
try {
// Get the ContractFactory of your MyToken contract
const MyToken = await hre.ethers.getContractFactory("MyToken");
// Connect to the deployed contract
const contractAddress = "0x543ba9FC0ade6f222BD8C7Bf50a0CD9923Faf569"; // Replace with your deployed contract address
const contract = await MyToken.attach(contractAddress);
// Retrieve the balance of an account
const account = "0x28eb8D29e4713E211D1dDab19dF3de16086BB8fa";
const balance = await contract.balanceOf(account);
// Retrieve the symbol of the token
const symbol = await contract.symbol();
console.log(
`Balance of ${account} account: ${balance.toString()} ${symbol}`
);
} catch (error) {
console.error(error);
process.exit(1);
}
}
main();
```
![Successful Compile](/img/guides/quickstart/hardhat/successful-compile-remix.png)
- And run the interaction script. This is how you can do it on testnet:
- Choose `Deploy and Run Transactions` and in `Environment`, Choose "Injected Provider - Metamask".
```
npx hardhat run scripts/interact.js --network rskTestnet
```
This loads the Metamask wallet.
- And this is how you can do it on mainnet:
![Deploy and Run Transactions](/img/guides/quickstart/hardhat/deploy-and-run-tx-remix.png)
```
npx hardhat run scripts/interact.js --network rskMainnet
```
Now click on `Transactions recorded` interact with the Smart Contract! Call its functions, send transactions, and observe the results. Ensure you have enough tRBTC in your MetaMask wallet for transaction fees.
- The expected output by running the interaction script is:
- Monitor Transactions
- Use Remix and MetaMask to monitor transaction confirmations and results.
- You can also use a [Rootstock Testnet Explorer](https://explorer.testnet.rootstock.io/) to view transactions and contract interactions.
