How to Integrate NEAR Wallet Selector into Your dApp

In the world of decentralized applications (dApps), implementing a seamless wallet interface is crucial. The NEAR Wallet Selector provides an elegant solution, allowing users to interact with various wallets within the NEAR ecosystem effortlessly. This guide walks you through the steps needed to integrate the NEAR Wallet Selector into your dApp, making the user experience as smooth as possible.

Understanding NEAR Wallet Selector

Think of NEAR Wallet Selector as a keyring that holds various keys (wallets). Just as a keyring helps you securely keep all your keys organized and accessible, NEAR Wallet Selector allows users to easily select and interact with their preferred wallets while using your dApp. This abstraction simplifies the wallet connection process, so users don’t have to worry about navigating through individual wallets.

Installation and Usage

To get started, you will need to install the NEAR Wallet Selector’s core package along with any specific wallets you wish to support in your dApp.

Step 1: Install Core Packages

Use either Yarn or NPM to install the necessary packages:

• yarn add near-api-js
• npm install near-api-js
• yarn add @near-wallet-selector/core
• npm install @near-wallet-selector/core

Step 2: Install Desired Wallet Packages

Next, choose the wallets you want to support and install them individually. Here’s how you can do that:

• yarn add @near-wallet-selector/my-near-wallet
• npm install @near-wallet-selector/my-near-wallet
• (Repeat for each wallet needed, such as @near-wallet-selector/ledger, @near-wallet-selector/sender, etc.)

Step 3: Install Modal UI (Optional)

If you prefer a pre-built interface, install the modal-ui package:

• yarn add @near-wallet-selector/modal-ui
• npm install @near-wallet-selector/modal-ui

Example Code Integration

Once everything is installed, it’s time to synthesize the code into your dApp. Below is an example of how to set up the wallet selector and modal:

import setupWalletSelector from '@near-wallet-selector/core';
import setupModal from '@near-wallet-selector/modal-ui';
import setupMyNearWallet from '@near-wallet-selector/my-near-wallet';
import setupLedger from '@near-wallet-selector/ledger';

const selector = await setupWalletSelector({
  network: 'testnet',
  modules: [
    setupMyNearWallet(),
    setupLedger(),
    // Add other wallets as needed...
  ],
});

const modal = setupModal(selector, {
  contractId: 'your-contract-id.testnet',
});

Troubleshooting

If you encounter issues during the integration process, consider the following troubleshooting tips:

• Ensure all packages are correctly installed and there are no typos in import statements.
• Check for network connectivity issues that might prevent wallet functions from executing properly.
• Consult the README document of each wallet package for specific instructions or additional dependencies.
