One of the most important features of decentralized applications (DApps) is the capability to connect a wallet, which enables the user to interact with DApp transactions. It abstracts features like switching networks and providing signers that provide users with a form of authentication. Clients can use their WalletConnect walletconnect application download, walletconnect download, walletconnect chrome expansion, or walletconnect address as an authorized personality to make and read transactions on the blockchain by connecting a wallet to the DApp.

The free, open-source WalletConnect protocol has enabled our DApps to connect to MetaMask, Trust Wallet, Rainbow, and other wallets. This protocol abstracts this process by establishing a connection between the DApp and the wallet and keeping them in sync throughout the session.

In this article, we will connect our wallet app to our DApp by utilizing WalletConnect with Vue.js as the front end. Any DApp, chain, or wallet—custodial or non-custodial—that is wallet-connect compatible can be used with WalletConnect.

How to start using a Vue.js app First, let's use the Vue CLI to start the project. You can start creating Vue projects right away if your framework has Vue CLI installed.

This command makes it possible to install globally:

After the project has been created, go to the new project folder:

cd vue-wallet-connect In our Vue app, we will use Ethers.js to connect our wallet and interact directly with the blockchain:

To install the WalletConnect library in your project, run npm install ethers here:

In order to use the WalletConnect library directly in Vue 3, you need to install the node-polyfill-webpack-plugin: npm install --save web3 @walletconnect/web3-provider Building the UI Let's create a brand-new file with the name StatusContainer.vue in the components folder for WalletConnect, the app download, the extension download, and the extension build. This component contains our main page.

There is a welcome message, a button to interact with the wallet, a button to disconnect, and a button to associate with the wallet. The Connected button finally appears when we successfully connect to a wallet:

Now, create a new walletConnect folder in the src folder: src/walletConnect. In this folder, let's make a provider.js file. Our WalletConnect library, which includes our Infura ID, is imported, launched, and sold for use in various documents.

Following the successful implementation of our interface and library, the next step is to use composables to implement our functionalities. Because Vue composables, like Pinia and Vuex, permit us to use our state and actions in any app component, we will use them to complete this task.

Add src/composables/connect to the src folder when creating a composable. Let's make a file called index.js in the connect folder.

Watch and reactive will be utilized in this file because they have been imported here. An object should be created for our defaultState state:

Utilize the "vue" wallet connect chrome extension to import reactive, then watch from WalletConnect.

address: status: const defaultState = "; "; status of chainId: false,

};

We synchronize the state with a nearby stockpiling thing to keep up with consistency. In the STATE_NAME variable, give this thing the name "userState." This is done to avoid errors when reusing "userState" in WalletConnect, the application download for WalletConnect, the download for WalletConnect, and the WalletConnect chrome extension at various locations: const state = defaultState
