Introduction

The Planq Network is a blockchain platform designed to support the creation and deployment of decentralized applications (dApps) and smart contracts. In this tutorial, we will guide you through the process of deploying a smart contract on the Planq Network. Whether you are a seasoned blockchain developer or a beginner, this step-by-step guide will help you get started.

Prerequisites:

Before you begin, ensure you have the following:

1. **Planq Wallet**: A wallet that supports the Planq Network.

2. **Planq Tokens**: Some Planq tokens for transaction fees.

3. **Development Environment**: Node.js and npm installed on your system.

4. **Smart Contract Code**: A smart contract written in Solidity.

### Step 1: Set Up Your Development Environment

First, set up your development environment by installing the necessary tools. Ensure you have Node.js and npm installed. You can download them from [Node.js](https://nodejs.org/).

Next, install Truffle, a development framework for Ethereum which is compatible with the Planq Network:

```bash

npm install -g truffle

```

### Step 2: Write Your Smart Contract

Create a new directory for your project and navigate to it:

```bash

mkdir planq-smart-contract

cd planq-smart-contract

```

Initialize a new Truffle project:

```bash

truffle init

```

In the `contracts` directory, create a new Solidity file, e.g., `MyContract.sol`, and write your smart contract code:

```solidity

pragma solidity ^0.8.0;

contract MyContract {

string public message;

constructor(string memory _message) {

message = _message;

}

function setMessage(string memory _message) public {

message = _message;

}

}

```

### Step 3: Configure the Planq Network

In the `truffle-config.js` file, configure the Planq Network settings:

```javascript

module.exports = {

networks: {

planq: {

provider: () => new HDWalletProvider(

'YOUR_MNEMONIC', // Replace with your wallet mnemonic

'https://rpc.planq.network' // Planq Network RPC URL

),

network_id: '*', // Any network ID

gas: 4500000,

gasPrice: 10000000000,

},

},

compilers: {

solc: {

version: "0.8.0",

},

},

};

```

### Step 4: Compile Your Smart Contract

Compile your smart contract using Truffle:

```bash

truffle compile

```

### Step 5: Deploy Your Smart Contract

Create a new migration file in the `migrations` directory, e.g., `2_deploy_contracts.js`, and add the deployment script:

```javascript

const MyContract = artifacts.require("MyContract");

module.exports = function (deployer) {

deployer.deploy(MyContract, "Hello, Planq!");

};

```

Deploy your smart contract to the Planq Network:

```bash

truffle migrate --network planq

```

### Step 6: Interact with Your Smart Contract

Once deployed, you can interact with your smart contract using Truffle console or by creating a front-end application. To use the Truffle console:

```bash

truffle console --network planq

```

Within the console, you can interact with your contract:

```javascript

const instance = await MyContract.deployed();

const message = await instance.message();

console.log(message);

```

### Conclusion

Deploying a smart contract on the Planq Network is a straightforward process if you are familiar with Ethereum development tools like Truffle. By following these steps, you can easily deploy and interact with your smart contracts on the Planq Network. Happy coding!
