How to Create a Wallet Login with ReOwn
Secure and User-Friendly Wallet Logins with ReOwn’s AppKit(Formerly Wallet Connect)
In the evolving Web3 ecosystem, building a seamless and secure wallet login is essential for enhancing user experience. ReOwn provides a robust framework with its AppKit and integration with wagmi, making wallet authentication easier for developers while ensuring secure handling of digital assets.
This article guides you through creating a wallet login using ReOwn, covering essential code snippets, best practices, and explanations for each step.
Introduction
With the rapid growth of decentralized applications (dApps), the need for secure and user-friendly wallet login systems is greater than ever. ReOwn’s AppKit offers a powerful suite of tools to simplify onboarding and wallet management through social login integrations and smart accounts. This guide aims to help developers implement a secure and scalable wallet login system, combining ReOwn’s smart account features with popular authentication libraries like wagmi. By the end of this article, you’ll understand how to implement wallet login functionality using best practices, ensuring an optimal user experience.
Step 1: Setting Up Your Environment
Before diving into the wallet login implementation, ensure you have the right environment set up for using ReOwn’s AppKit. Here’s a basic setup using Next.js as the framework, though you can adapt it to any frontend technology.
Installation of Dependencies
Start by installing the necessary dependencies. You’ll need wagmi, ethers, and ReOwn’s AppKit to enable wallet connectivity and manage accounts.
npm install wagmi ethers @reown/appkitThis installs the required packages, including wagmi (a Web3 hooks library) and ethers (a widely-used Ethereum library).
Step 2: Initialize the ReOwn SDK
Now, you’ll need to initialize ReOwn’s SDK within your project. This SDK provides the methods necessary for managing user accounts and integrating wallet functionality. In pages/_app.js, add the following code:
import { ReOwnProvider } from '@reown/appkit';
import { WagmiConfig, createClient } from 'wagmi';
const client = createClient({
autoConnect: true,
provider: new ethers.providers.JsonRpcProvider(process.env.NEXT_PUBLIC_RPC_URL),
});
function MyApp({ Component, pageProps }) {
return (
<WagmiConfig client={client}>
<ReOwnProvider>
<Component {...pageProps} />
</ReOwnProvider>
</WagmiConfig>
);
}
export default MyApp;This sets up wagmi and the ReOwn Provider in your app. The createClient function auto-connects the wallet and manages interactions using the configured JSON-RPC provider.
Why this setup is important:
- Auto-connect: This provides a seamless login experience by automatically reconnecting the user’s wallet, improving user retention.
- ReOwnProvider: Provides access to ReOwn features such as social logins and smart accounts.
Step 3: Implementing Wallet Login UI
Creating the UI for wallet login is crucial for providing users with an intuitive experience. Using ReOwn’s AppKit, you can add wallet login buttons that support multiple options, such as MetaMask or WalletConnect.
import { useAccount, useConnect, useDisconnect } from 'wagmi';
import { InjectedConnector } from 'wagmi/connectors/injected';
function WalletLogin() {
const { connect } = useConnect({
connector: new InjectedConnector(),
});
const { disconnect } = useDisconnect();
const { isConnected } = useAccount();
return (
<div>
{isConnected ? (
<button onClick={() => disconnect()}>Disconnect Wallet</button>
) : (
<button onClick={() => connect()}>Connect Wallet</button>
)}
</div>
);
}
export default WalletLogin;This simple UI allows users to connect or disconnect their wallet. Here’s what happens under the hood:
- useConnect: This hook connects the user’s wallet (e.g., MetaMask).
- useDisconnect: This hook disconnects the user’s wallet, providing a clean and easy logout experience.
- useAccount: This hook checks if the user is currently connected to a wallet.
Best Practice:
Ensure you provide feedback for both successful and unsuccessful login attempts. It improves user trust and provides clear guidance in case something goes wrong.
Step 4: Smart Account Integration
ReOwn’s strength lies in its smart accounts, which allow users to manage multiple wallets and social logins efficiently. To integrate smart accounts, use ReOwn’s AppKit, as demonstrated below:
import { useSmartAccount } from '@reown/appkit';
function SmartAccountLogin() {
const { createSmartAccount, account } = useSmartAccount();
const handleLogin = async () => {
const account = await createSmartAccount();
console.log("Smart Account Created:", account);
};
return (
<div>
<button onClick={handleLogin}>Login with Smart Account</button>
</div>
);
}
export default SmartAccountLogin;This snippet demonstrates how to create a smart account for a user. The createSmartAccount method generates a wallet that the user can manage directly through the dApp.
Why smart accounts matter:
- Enhanced Security: Smart accounts enable multi-signature wallets, improving security.
- Multiple Wallets: Users can manage multiple wallets under a single account, simplifying account recovery and switching between wallets.
Step 5: Social Login Integration
ReOwn’s AppKit supports social logins like Google and Twitter, allowing users to log in without needing a traditional Web3 wallet. Here’s how to add a social login button:
import { useSocialLogin } from '@reown/appkit';
function SocialLogin() {
const { loginWithGoogle } = useSocialLogin();
return (
<div>
<button onClick={() => loginWithGoogle()}>Login with Google</button>
</div>
);
}
export default SocialLogin;In this example, users can log in using their Google account. ReOwn handles the underlying OAuth flow, making it easy for developers to implement.
Best Practice:
Provide fallback options in case the social login service is down or unavailable. Always give users the ability to log in via their Web3 wallet to avoid reliance on third-party services.
Step 6: Error Handling and Notifications
Proper error handling is essential in wallet interactions. Web3 wallets and smart contracts are prone to failures due to network issues, wallet disconnections, or failed transactions. Here’s how you can add basic error handling:
import { useConnect } from 'wagmi';
function WalletLogin() {
const { connect, error } = useConnect();
const handleConnect = async () => {
try {
await connect();
} catch (err) {
console.error("Connection Error:", err.message);
}
};
return (
<div>
<button onClick={handleConnect}>Connect Wallet</button>
{error && <p>Error: {error.message}</p>}
</div>
);
}
export default WalletLogin;This ensures that any errors during the login process are caught and displayed to the user, enhancing transparency and debugging.
Conclusion
Integrating wallet login functionality using ReOwn’s AppKit and wagmi provides a robust, secure, and user-friendly system for Web3 applications. Whether using smart accounts, social logins, or traditional wallets, ReOwn offers flexibility and scalability. Following best practices such as error handling, providing multiple login options, and ensuring secure connections will improve the reliability and user experience of your dApp.
By using ReOwn, developers can take advantage of modern wallet management features while building for the future of decentralized applications.
