How to build a Dapp - Interacting with a smart contract using React and Ethers / useDApp
Overview
In the first tutorial, we created a simple smart contract for our tower and deployed it to the Rinkeby testnet blockchain. Now, in this second part, we’ll take the next step: building a frontend with React and learning how to interact with the deployed smart contract using the Ethers library and the useDApp framework.
By the end of this tutorial, you’ll have a functional React app that can connect to MetaMask, send transactions to the blockchain, and retrieve event logs from your contract.
Why Learn Smart Contract Interaction?
Building a smart contract is just the first step in Web3 development. To create a fully functional decentralized application, you need a frontend that allows users to interact with the blockchain. This tutorial will help you understand:
-
How to check if a wallet is installed and connect it to your website.
-
How to verify if the wallet is on the correct blockchain network.
-
How to create transactions and interact with the smart contract.
-
How to retrieve event logs from your contract.
Insights and Skills
Throughout this tutorial, you’ll gain hands-on experience with:
-
Connecting a React application to MetaMask.
-
Using Ethers.js to interact with the Ethereum blockchain.
-
Using useDApp to simplify blockchain interactions in React.
-
Sending transactions to create new floors in the tower.
-
Retrieving and displaying event logs from the smart contract.
