• Connect to popular N20 compatible (Unisat, ChainBow and NOTEMarketWallet)
• Manage Bitcoin addresses and check balances
• Send and receive Bitcoin transactions
• Sign messages and PSBTs
• Push transactions and PSBTs to the network
• Switch between different connectors and networks
• Customizable UI theme (light and dark)
• Typescript support
• Support for React components
• Support for pure JavaScript usage (compatible with Vue, vanilla JS, etc.)

Installation

You can install the package via npm, yarn, pnpm or bun:

npm

npm install n20-connect

Yarn

yarn add n20-connect

pnpm

pnpm add n20-connect

bun

bun add n20-connect

Requirements

For React:

• react (>=16.8.0)
• react-dom (>=16.8.0)

The library also uses the zustand state management library for React hooks.

Usage

React

Import the WalletConnectReact component and wrap your application with it:

import React from 'react';
import { WalletConnectReact } from 'n20-connect/dist/react';
import "n20-connect/dist/style/index.css";

const App = () => {
  const config = {
    network: 'BTClivenet', // or 'testnet'
    defaultConnectorId: 'chainbow', // or 'chainbow'
  };

  return (
    <WalletConnectReact
      config={config}
      onConnectSuccess={(btcWallet) => {
        // Handle successful connection
      }}
      theme="dark"
      onConnectError={(error) => {
        // Handle connection error
      }}
      onDisconnectSuccess={() => {
        // Handle successful disconnection
      }}
      onDisconnectError={(error) => {
        // Handle disconnection error
      }}
    >
      {/* Your app components */}
    </WalletConnectReact>
  );
};

export default App;

You can also use the useReactWalletStore hook to access the wallet store and perform various actions:

import React from 'react';
import { useReactWalletStore } from 'n20-connect/dist/react';

const MyComponent = () => {
  const walletStore = useReactWalletStore();

  const connect = () => {
    walletStore.connect();
  };

  const disconnect = () => {
    walletStore.disconnect();
  };

  const sendBitcoin = async () => {
    const toAddress = '...';
    const amount = 1000;
    const txid = await walletStore.btcWallet?.sendToAddress(toAddress, amount);
    console.log('Transaction ID:', txid);
  };

  return (
    <div>
      <button onClick={connect}>Connect</button>
      <button onClick={disconnect}>Disconnect</button>
      <button onClick={sendBitcoin}>Send Bitcoin</button>
    </div>
  );
};

export default MyComponent;

Pure JavaScript

You can use the BtcWalletConnect class directly in your JavaScript code:

import BtcWalletConnect from 'n20-connect';

const config = {
  network: 'BTClivenet', // or 'testnet'
  defaultConnectorId: 'chainbow', // or 'chainbow'
};

const btcWallet = new BtcWalletConnect(config);

// Connect to the wallet
btcWallet.connect()
  .then(() => {
    // Handle successful connection
  })
  .catch((error) => {
    // Handle connection error
  });

// Send Bitcoin
const toAddress = '...';
const amount = 1000;
btcWallet.sendToAddress(toAddress, amount)
  .then((txid) => {
    console.log('Transaction ID:', txid);
  })
  .catch((error) => {
    // Handle error
  });

// Disconnect from the wallet
btcWallet.disconnect()
  .then(() => {
    // Handle successful disconnection
  })
  .catch((error) => {
    // Handle disconnection error
  });

This pure JavaScript usage makes it compatible with Vue, vanilla JavaScript, and other frameworks or libraries.
