### 📜 **Overview: What's Inside?**

In this section, you'll find everything you need to confidently deploy and interact with smart contracts using Hardhat:

1. **Environment Setup**: Quickly get ready with Hardhat. We'll show you how step by step.
2. **Your Network in `hardhat.config.js`**: Customize for Swisstronik. Learn to use `hardhat.config.js` for network setup.
3. **Smart Contracts**: Create a contract in Solidity to set and retrieve messages.
4. **Deploy Contracts**: Deploy your smart contract into the Swisstronik blockchain
5. **Transactions**: Execute a transaction to set a message in the smart contract using `sendShieldedTransaction`
6. **Calls**: Talk to your deployed smart contract. Retrieve the message using `sendShieldedQuery`
