Frontend Made Easy: Integrating Bitcoin Wallets with BTC Connect Open-Source Library

·

Integrating Bitcoin wallet functionality into web applications has long been a challenge for developers—especially those working independently. Complex APIs, inconsistent wallet support, and steep learning curves often stand in the way of seamless implementation. That’s why we’re excited to introduce BTC Connect, an open-source library designed to simplify Bitcoin integration for frontend developers.

Whether you're building a decentralized exchange, a blockchain-based game, or a financial tool, BTC Connect streamlines the process of connecting users to their Bitcoin wallets, managing addresses, checking balances, sending transactions, and signing messages—all with minimal code and maximum flexibility.

👉 Discover how easy Bitcoin integration can be with the right tools.

Why BTC Connect Was Built

As blockchain technology evolves, demand for native Bitcoin interactions in web apps is growing. However, existing solutions often require deep expertise in cryptographic protocols or rely on fragmented, wallet-specific implementations. This creates friction for developers and limits user accessibility.

BTC Connect was created to solve these problems by offering a unified, developer-friendly interface that abstracts away complexity without sacrificing control. It supports popular Bitcoin wallets like Unisat and OKX while providing a consistent API across environments—whether you're using React, vanilla JavaScript, or TypeScript.

The goal? Lower the barrier to entry so more projects can participate in the Bitcoin ecosystem—securely, efficiently, and intuitively.

Key Features That Set BTC Connect Apart

✅ Broad Wallet Compatibility

BTC Connect natively supports leading Bitcoin wallets including Unisat and OKX Wallet, ensuring your users can connect regardless of their preferred tool. This interoperability reduces onboarding friction and increases adoption rates.

✅ Full-Featured Bitcoin Interaction

From basic address management to advanced transaction handling, BTC Connect covers all essential use cases:

All operations are exposed through a clean, promise-based API that integrates smoothly into modern web workflows.

✅ Framework Flexibility

Whether you're building a React-powered dApp or a lightweight static site, BTC Connect adapts to your stack:

TypeScript support ensures type safety and better IDE integration—ideal for large-scale applications.

✅ Customizable UI Experience

User experience matters. BTC Connect includes built-in support for both light and dark themes, allowing you to match your app’s visual style. You can also extend or replace default UI elements to maintain brand consistency.


Getting Started in Minutes

Setting up BTC Connect takes just a few steps. Installation is straightforward via npm or yarn:

npm install btc-connect
# or
yarn add btc-connect

For React Projects

Wrap your application with the provided React component:

import { WalletConnectReact } from 'btc-connect/dist/react';
import "btc-connect/dist/style/index.css";

function App() {
  return (
    <WalletConnectReact config={{ network: 'livenet', defaultConnectorId: 'unisat' }}>
      {/* Your app content */}
    </WalletConnectReact>
  );
}

This automatically handles wallet detection, connection states, and event propagation.

For Non-React Applications

Use the core class directly:

import BtcWalletConnect from 'btc-connect';

const btcWallet = new BtcWalletConnect({ 
  network: 'livenet', 
  defaultConnectorId: 'unisat' 
});

// Now interact with the wallet
btcWallet.connect().then(() => {
  console.log('Connected:', btcWallet.getAddress());
});

You can then call methods like sendBitcoin(toAddress, amount) or signMessage("Hello") as needed.

Use Cases and Practical Applications

BTC Connect isn’t just for experimental projects—it’s built for production use. Here are some real-world scenarios where it adds immediate value:

🛍️ E-Commerce Platforms Accepting BTC

Enable merchants to accept Bitcoin payments by embedding a lightweight wallet connector. Users can pay directly from their preferred wallet without leaving the site.

🎮 Web3 Games with Bitcoin Rewards

Integrate Bitcoin rewards or in-game asset transfers using secure message signing and transaction broadcasting—all handled client-side.

📊 On-Chain Analytics Dashboards

Allow users to connect their wallets and view transaction history, balance trends, or UTXO breakdowns without exposing private keys.

🗳️ Decentralized Voting Systems

Leverage message signing to authenticate voters while preserving anonymity—perfect for community governance models powered by Bitcoin.


Frequently Asked Questions (FAQ)

Q: Is BTC Connect non-custodial?
A: Yes. BTC Connect never accesses or stores private keys. All signing operations occur within the user’s wallet (e.g., Unisat or OKX), ensuring full control remains with the owner.

Q: Which networks does it support?
A: Currently, BTC Connect supports both livenet (mainnet) and testnet. Developers can switch between them during initialization for testing purposes.

Q: Can I customize the connection flow?
A: Absolutely. While default modals are provided, you can build custom UIs using the underlying API and respond to connection events like connect, disconnect, and accountsChanged.

Q: Does it work with Ordinals or BRC-20 tokens?
A: While BTC Connect focuses on core Bitcoin functionality, it enables address and transaction management that can be extended to support Ordinals-aware services. Full BRC-20 support may require additional tooling but is compatible at the address level.

Q: Is it open source? Can I contribute?
A: Yes! BTC Connect is fully open source under MIT license. Contributions—from bug fixes to new wallet connectors—are welcome on GitHub.


BTC Connect represents a step forward in making Bitcoin more accessible to developers and end users alike. By reducing technical complexity and supporting widely used tools like OKX Wallet, it empowers teams to focus on innovation rather than infrastructure.

Whether you're launching a new dApp or enhancing an existing platform, BTC Connect offers a reliable, lightweight path to Bitcoin integration.
