The ability to connect a wallet, which enables the user to interact with DApp transactions, is one of the most important features of decentralized applications (DApps). It abstracts features that provide users with a form of authentication, such as switching networks and providing signers. By connecting a wallet to the DApp, customers can make and read transactions on the blockchain using their WalletConnect, walletconnect application download, walletconnect download, walletconnect chrome expansion, or walletconnect address as an authorized person.
Our DApps have been able to connect to MetaMask, Trust Wallet, Rainbow, and other wallets thanks to the open-source, free WalletConnect protocol. By establishing a connection between the DApp and the wallet and keeping them in sync throughout the session, this protocol abstracts this process.
Using Vue.js as the front end, we will use WalletConnect to connect our wallet app to our DApp in this article. WalletConnect can be used with any DApp, chain, or wallet—custodial or non-custodial—that is wallet-connect compatible.
How to get started with a Vue.js app First, let's start the project with the Vue CLI. If your framework includes the Vue CLI, you can immediately begin creating Vue projects.
Global installation is made possible by this command:
Navigate to the new project folder after the project has been created:
cd vue-wallet-connect In our Vue app, we will connect our wallet to the blockchain and use Ethers.js to do so:
Run npm install ethers here to install the WalletConnect library in your project:
You need to install the node-polyfill-webpack-plugin in Vue 3 in order to use the WalletConnect library directly: npm install --save web3 @walletconnect/web3-provider Building the UI Let's create a brand-new file in the components folder for WalletConnect, the app download, the extension download, and the extension build with the name StatusContainer.vue. Our main page is contained in this component.
There is a button to associate with the wallet, a button to disconnect, a button to interact with the wallet, and a welcome message. When we successfully connect to a wallet, the Connected button finally appears:
Now, in the src folder, create a new walletConnect folder: src/walletConnect. Let's create a provider.js file in this folder. Our Infura ID is included in our WalletConnect library, which is imported, launched, and sold for use in various documents.
Utilizing composables to implement our functionalities is the next step after our interface and library have been successfully implemented. We will use Vue composables, like Pinia and Vuex, to complete this task because they allow us to use our state and actions in any app component.
When creating a composable, add src/composables/connect to the src folder. In the connect folder, let's create a file called index.js.
Because they were imported here, watch and reactive will be used in this file. For our defaultState state, an object needs to be created:
Import reactive using the "vue" wallet connect chrome extension, and then watch from WalletConnect.
address: status: defaultState const = "; "; status of chainId: false,
};
In order to maintain consistency, we synchronize the state with a nearby stockpiling device. Give this thing the name "userState" in the STATE_NAME variable. When reusing "userState" in WalletConnect, the application download for WalletConnect, the download for WalletConnect, and the WalletConnect chrome extension at various locations, this is done to prevent errors: defaultState is the const state.
