Smart Contracts Programming Tutorials, Guides & Best Practices

• Follow the prompts to create a basic Hardhat sample project.

• Install the OpenZeppelin Contracts library:

Decentralized applications (DApps) represent the future of software, leveraging blockchain technology to create applications that are transparent, secure, and free from centralized control. By combining smart contracts with a user interface, DApps offer a new way to interact with blockchain technology. In this tutorial, we will guide you through the process of building a DApp on the Ethereum blockchain. You’ll learn how to create a simple DApp, connect it to a smart contract, and deploy it on a test network.

A decentralized application (DApp) is an application that runs on a peer-to-peer network, like a blockchain, rather than relying on a single centralized server. DApps are open-source, operate autonomously, and the data is stored on the blockchain, making them transparent and resistant to censorship.

• Switch to the "Deploy & Run Transactions" tab.
• Select "Injected Web3" as the environment to connect to MetaMask.
• Choose a test network like Ropsten or Kovan in MetaMask.
• Click "Deploy" and confirm the transaction in MetaMask.

• Once deployed, the contract will appear in the "Deployed Contracts" section.
• You can now call the set and get functions to interact with your contract.
