# How to build a basic dApp with Scaffold-ETH

In this guide, you will learn how to use Scaffold-ETH 2 to quickly build a new dapp project.

## Requirements

Before you begin, you need to install the following tools:

* Node (>= v18.18)
* Yarn (v1 or v2+)
* Git

### Get funds on Monad Testnet

You will need funds on Monad Testnet in order to deploy smart contracts, you can get funds from the [Monad Faucet](https://testnet.monad.xyz).

## Working with Scaffold-ETH

Scaffold-ETH can have two different solidity development frameworks: Foundry and Hardhat.

In this guide you can choose between Foundry and Hardhat.

    ### Clone the scaffold-monad-foundry repo

    ```sh theme={null}
    git clone https://github.com/monad-developers/scaffold-monad-foundry.git
    ```

    ### Open the project directory and install dependencies

    ```sh theme={null}
    cd scaffold-monad-foundry && yarn install
    ```

    ### Start your local blockchain node

    ```sh theme={null}
    yarn chain
    ```

    ### Deploy your smart contract to your local blockchain node

    ```sh theme={null}
    yarn deploy
    ```

    This command deploys `YourContract.sol` to your local blockchain node. The contract is located in `packages/foundry/contracts` and can be modified to suit your needs.

    The `yarn deploy` command uses the deploy script located in `packages/foundry/deploy` to deploy the contract to the network. You can also customize the deploy script.

    ### Start your NextJS app

    ```sh theme={null}
    yarn start
    ```

    Visit your app on: `http://localhost:3000`.

    You can interact with your smart contract using the Debug Contracts page. You can tweak the app config in `packages/nextjs/scaffold.config.ts`.

    ### Deploy your smart contract to Monad Testnet

    ```sh theme={null}
    yarn deploy --network monadTestnet
    ```

    This command deploys `YourContract.sol` to Monad Testnet. The contract is located in `packages/foundry/contracts` and can be modified to suit your needs.

    ### Verify your smart contract on Monad Testnet

    ```sh theme={null}
    yarn verify --network monadTestnet
    ```

    This command verifies `YourContract.sol` on Monad Testnet.

    ```

    ### Open the project directory and install dependencies

    ```sh theme={null}
    cd scaffold-monad-hardhat && yarn install
    ```

    ### Start your local blockchain node

    ```sh theme={null}
    yarn chain
    ```

    ### Deploy your smart contract to your local blockchain node

    ```sh theme={null}
    yarn deploy
    ```

    This command deploys `YourContract.sol` to your local blockchain node. The contract is located in `packages/hardhat/contracts` and can be modified to suit your needs.

    The `yarn deploy` command uses the deploy script located in `packages/hardhat/deploy` to deploy the contract to the network. You can also customize the deploy script.

    ### Start your NextJS app

    ```sh theme={null}
    yarn start
    ```

    Visit your app on: `http://localhost:3000`.

    You can interact with your smart contract using the Debug Contracts page. You can tweak the app config in `packages/nextjs/scaffold.config.ts`.

    ### Generate a deployer account

    ```sh theme={null}
    yarn generate
    ```

    This command will create a new deployer account. **Remember the password you create** as you'll need it for deployments.

    ### Deploy your smart contract to Monad Testnet

    ```sh theme={null}
    yarn deploy --network monadTestnet
    ```

    This command deploys `YourContract.sol` to Monad Testnet. The contract is located in `packages/hardhat/contracts` and can be modified to suit your needs.

    ### Verify your smart contract on Monad Testnet

    ```sh theme={null}
    yarn verify --network monadTestnet
    ```

    This command verifies `YourContract.sol` on Monad Testnet.
