How to interact with your smart contract using React, useDApp and Ethers ?

In the first tutorial we made a simple smart contract for our tower and deployed it to rinkeby testnet blockchain.

In this second video we create a frontend with React and interact with the deployed smart contract using Ethers library and useDApp framework.

What you'll learn :

• How to check if a wallet is installed, connect it to your website and check if it is connected to the correct chain

• How to create transactions and create new floors on the tower

• How to get the event logs from your contract
