The use-wallet library is a powerful, lightweight solution designed to simplify decentralized application (DApp) development. It provides front-end developers with a set of intuitive hooks and functions to interact seamlessly with various blockchain wallets, eliminating the need for complex provider management. Ideal for React and Vue3 projects, this tool streamlines the integration process while maintaining high performance and flexibility.
Core Features and Advantages
Multi-Chain and Multi-Wallet Support
Use-wallet offers broad compatibility across different blockchain networks and digital wallets. It natively supports Conflux and Ethereum chains, along with popular wallet providers like Portal, Fluent, MetaMask, MetaX, and CoinBase. This versatility allows developers to build applications that cater to diverse user preferences and network requirements.
Simplified Development Experience
By abstracting away low-level provider complexities, use-wallet enables developers to focus on core functionality. The library's high-level encapsulation means you can implement wallet connectivity and blockchain interactions without deep knowledge of underlying specifications. This approach significantly reduces development time and learning curves.
Optimized Performance with Fine-Grained Hooks
One of the standout features of use-wallet is its fine-grained hook system. Unlike other libraries that return bundled data causing unnecessary re-renders, use-wallet provides targeted hooks that minimize performance overhead. This results in smoother user experiences and more efficient applications.
Lightweight and Efficient
With a minimal footprint of just 3.7kb (gzip) without decimal.js or 20kb including it, use-wallet is significantly lighter than comprehensive SDK alternatives. This makes it perfect for projects where bundle size matters, without sacrificing essential functionality for most DApp development scenarios.
Installation and Setup
Installing use-wallet is straightforward using package managers like Yarn. For React-based projects, use the following command:
yarn add @cfxjs/use-wallet-reactFor Vue3 applications, install the corresponding package:
yarn add @cfxjs/use-wallet-vueThese packages provide framework-specific implementations while maintaining consistent API patterns across different environments.
Getting Started with Basic Implementation
React Implementation Example
Here's a basic example demonstrating how to integrate use-wallet in a React component:
import React, { memo, useCallback } from 'react';
import { useStatus, useAccount, useChainId, useBalance, connect, Unit } from '@cfxjs/use-wallet-react/conflux';This import pattern provides access to essential hooks for checking connection status, accessing account information, retrieving chain IDs, and managing balances.
Ethereum and MetaMask Integration
For Ethereum-based applications or MetaMask integration, use the alternative import path:
import { useStatus, ... } from '@cfxjs/use-wallet-react/ethereum/MetaMask'The consistent API structure across different chains and wallets makes it easy to switch between environments without rewriting core logic.

These projects provide excellent starting points for understanding how to integrate use-wallet into different types of applications, from simple prototypes to production-ready DApps.
Frequently Asked Questions
What makes use-wallet different from other wallet integration libraries?
Use-wallet focuses specifically on front-end development needs with a lightweight, hook-based approach. Unlike comprehensive SDKs, it avoids unnecessary bloat while providing essential wallet interaction capabilities. The fine-grained hooks prevent unnecessary re-renders, improving application performance compared to bulk data return approaches.
Which frameworks are supported by use-wallet?
The library currently provides dedicated support for React and Vue3 frameworks. The consistent API design across these frameworks allows developers to apply similar patterns regardless of their chosen technology stack. The vanilla JavaScript demo also demonstrates how to use the core functionality without any framework.
Can use-wallet connect to multiple blockchain networks?
Yes, use-wallet supports multiple blockchain networks including Conflux and Ethereum. The library's architecture allows for extending support to additional networks through its flexible provider system. This multi-chain capability enables developers to build applications that can interact with different blockchain ecosystems.
How does the performance optimization work in use-wallet?
The library uses fine-grained hooks that return only specific pieces of data rather than bundling all wallet information together. This approach prevents React components from re-rendering when unrelated wallet data changes, significantly improving performance in complex applications with multiple wallet interactions.
Is use-wallet suitable for production applications?
Absolutely. While lightweight, use-wallet provides robust functionality for production DApp development. The library handles essential wallet interactions, connection management, and state tracking while maintaining a small footprint. However, for advanced blockchain operations beyond basic wallet interactions, you might need additional libraries.
What wallets can users connect with through use-wallet?
The library supports popular wallet options including Portal, Fluent, MetaMask, MetaX, and CoinBase. This coverage ensures that most users can connect with their preferred wallet provider without compatibility issues. The consistent interface across different wallets simplifies the development process significantly.
