Wallet Client Integration

Module 3B: Connecting to User Wallets (Frontend Paradigm)

This module teaches you how to integrate MetaNet Desktop Wallet into your dApp using the BSV SDK's WalletClient component. This is the standard approach for building non-custodial BSV applications where users control their own keys.

Note: This module is for Frontend Integration Development. If you're building backend services where you control keys, see Managing Wallets Server-Side instead.

What is WalletClient?

WalletClient is a pre-built SDK component that:

✅ Connects your dApp to BSV Desktop (MetaNet Desktop Wallet)
✅ Requests user signatures for transactions
✅ Handles all wallet communication via BRC protocol
✅ Manages UTXO selection (wallet handles)
✅ Calculates fees automatically (wallet handles)
✅ Broadcasts transactions (wallet handles)

What is BSV Desktop?

BSV Desktop is the modern, standard wallet for BSV blockchain development. It provides:

🔐 Secure key management with phone-based recovery
🔄 Multi-network support (mainnet/testnet switching)
🎁 Welcome gift: 99,991 Satoshis to start exploring
🔗 Seamless app integration for blockchain applications
📱 Identity Key management for dApp authentication
💧 Built-in testnet faucet for developers

Download BSV Desktop: https://desktop.bsvb.tech/

You don't need to:

❌ Manage private keys
❌ Track UTXOs
❌ Calculate fees
❌ Handle change outputs
❌ Configure ARC broadcasting

The wallet does all of this for you!

Prerequisites

Before starting:

✅ Completed Development Environment Setup

Part 1: WalletClient Basics

Installation

WalletClient is included in @bsv/sdk:

npm install @bsv/sdk

Import

import { WalletClient } from '@bsv/sdk'

Core Methods

import { WalletClient, P2PKH } from '@bsv/sdk'

const wallet = new WalletClient('auto')

// Connect to user's wallet substrate
await wallet.connectToSubstrate()

// Get user's identity public key
const { publicKey } = await wallet.getPublicKey({ identityKey: true })

// Create and send a transaction (auto-signed and broadcast)
const result = await wallet.createAction({
  description: 'Send payment',
  outputs: [{
    lockingScript: new P2PKH().lock('recipient-address').toHex(),
    satoshis: 1000,
    outputDescription: 'Payment output'
  }]
})

const txid = result.txid

These are the main methods you'll use! WalletClient handles the complexity of key management, UTXO selection, and broadcasting.

Part 2: Connecting to MetaNet Desktop Wallet

Basic Connection

import { WalletClient } from '@bsv/sdk'

async function connectWallet() {
  try {
    // 1. Create WalletClient instance
    const wallet = new WalletClient('auto')

    // 2. Connect to the wallet substrate
    await wallet.connectToSubstrate()

    // 3. Get user's identity public key
    const { publicKey } = await wallet.getPublicKey({ identityKey: true })

    console.log('Connected to wallet, public key:', publicKey)
    return { wallet, publicKey }

  } catch (error: any) {
    if (error.code === 'USER_REJECTED') {
      console.log('User rejected connection')
    } else if (error.code === 'WALLET_NOT_FOUND') {
      console.log('MetaNet Desktop Wallet not installed')
    } else {
      console.error('Connection failed:', error.message)
    }
    throw error
  }
}

React Hook for Wallet Connection

// hooks/useWallet.ts
import { useState, useEffect } from 'react'
import { WalletClient } from '@bsv/sdk'

export interface WalletState {
  wallet: WalletClient | null
  publicKey: string | null
  connected: boolean
  connecting: boolean
  error: string | null
}

export function useWallet() {
  const [state, setState] = useState<WalletState>({
    wallet: null,
    publicKey: null,
    connected: false,
    connecting: false,
    error: null
  })

  const connect = async () => {
    setState(prev => ({ ...prev, connecting: true, error: null }))

    try {
      const wallet = new WalletClient('auto')
      await wallet.connectToSubstrate()

      const { publicKey } = await wallet.getPublicKey({ identityKey: true })

      setState({
        wallet,
        publicKey,
        connected: true,
        connecting: false,
        error: null
      })

      console.log('✅ Wallet connected, public key:', publicKey)
    } catch (error: any) {
      setState({
        wallet: null,
        publicKey: null,
        connected: false,
        connecting: false,
        error: error.message
      })

      console.error('❌ Connection failed:', error)
    }
  }

  const disconnect = async () => {
    // Note: WalletClient doesn't have a disconnect method
    // Simply clear local state
    setState({
      wallet: null,
      publicKey: null,
      connected: false,
      connecting: false,
      error: null
    })
  }

  // Auto-reconnect if wallet was previously connected
  useEffect(() => {
    const autoConnect = async () => {
      const wasConnected = localStorage.getItem('wallet_connected')
      if (wasConnected === 'true') {
        await connect()
      }
    }

    autoConnect()
  }, [])

  // Save connection state
  useEffect(() => {
    if (state.connected) {
      localStorage.setItem('wallet_connected', 'true')
    } else {
      localStorage.removeItem('wallet_connected')
    }
  }, [state.connected])

  return {
    ...state,
    connect,
    disconnect
  }
}

Wallet Connection Component

// components/WalletConnect.tsx
import React from 'react'
import { useWallet } from '../hooks/useWallet'

export const WalletConnect: React.FC = () => {
  const { publicKey, connected, connecting, error, connect, disconnect } = useWallet()

  if (connected && publicKey) {
    return (
      <div className="wallet-connected">
        <p>Connected: {publicKey.substring(0, 12)}...{publicKey.substring(publicKey.length - 12)}</p>
        <button onClick={disconnect}>Disconnect</button>
      </div>
    )
  }

  return (
    <div className="wallet-not-connected">
      {error && <p className="error">{error}</p>}

      <button
        onClick={connect}
        disabled={connecting}
      >
        {connecting ? 'Connecting...' : 'Connect Wallet'}
      </button>

      {!connecting && (
        <div className="wallet-instructions">
          <p>To connect:</p>
          <ul>
            <li>Install MetaNet Desktop Wallet</li>
            <li>Create or import a wallet</li>
            <li>Click "Connect Wallet"</li>
          </ul>
        </div>
      )}
    </div>
  )
}

Part 3: Sending Transactions

Simple Payment

import { WalletClient, P2PKH } from '@bsv/sdk'

async function sendPayment(
  wallet: WalletClient,
  recipientAddress: string,
  amountSatoshis: number
) {
  try {
    // Create action to send payment (auto-signed and broadcast)
    const result = await wallet.createAction({
      description: 'Send payment',
      outputs: [{
        lockingScript: new P2PKH().lock(recipientAddress).toHex(),
        satoshis: amountSatoshis,
        outputDescription: 'Payment to recipient'
      }]
    })

    console.log('Payment sent!')
    console.log('TXID:', result.txid)
    console.log('Amount:', amountSatoshis, 'satoshis')

    return result.txid

  } catch (error: any) {
    if (error.code === 'USER_REJECTED') {
      console.log('User cancelled payment')
    } else if (error.code === 'INSUFFICIENT_FUNDS') {
      console.log('User has insufficient balance')
    } else {
      console.error('Payment failed:', error.message)
    }
    throw error
  }
}

// Usage
const txid = await sendPayment(wallet, '1A1zP1...', 1000)

What Happens Under the Hood

When you call wallet.createAction():

WalletClient sends transaction request to MetaNet Desktop Wallet
Wallet popup appears showing transaction details
User reviews:
- Recipient address
- Amount to send
- Fee (calculated by wallet)
- Total deduction from balance
User approves or rejects
Wallet:
- Selects UTXOs
- Calculates optimal fee
- Creates change output
- Signs transaction
- Broadcasts to BSV network
WalletClient returns TXID

Your dApp never sees the private key!

Payment Component

// components/SendPayment.tsx
import React, { useState } from 'react'
import { WalletClient, P2PKH } from '@bsv/sdk'

interface SendPaymentProps {
  wallet: WalletClient
}

export const SendPayment: React.FC<SendPaymentProps> = ({ wallet }) => {
  const [recipient, setRecipient] = useState('')
  const [amount, setAmount] = useState('')
  const [sending, setSending] = useState(false)
  const [txid, setTxid] = useState<string | null>(null)
  const [error, setError] = useState<string | null>(null)

  const handleSend = async () => {
    setSending(true)
    setError(null)
    setTxid(null)

    try {
      // Validate inputs
      if (!recipient) throw new Error('Recipient address required')
      if (!amount || isNaN(Number(amount))) throw new Error('Valid amount required')

      const amountSats = Math.floor(Number(amount) * 100_000_000) // BSV to satoshis

      // Create action to send payment
      const result = await wallet.createAction({
        description: 'Send payment',
        outputs: [{
          lockingScript: new P2PKH().lock(recipient).toHex(),
          satoshis: amountSats,
          outputDescription: 'Payment to recipient'
        }]
      })

      setTxid(result.txid!)
      setRecipient('')
      setAmount('')

      console.log('✅ Payment successful:', result.txid)

    } catch (err: any) {
      if (err.code === 'USER_REJECTED') {
        setError('Payment cancelled by user')
      } else if (err.code === 'INSUFFICIENT_FUNDS') {
        setError('Insufficient balance in wallet')
      } else {
        setError(err.message || 'Payment failed')
      }
      console.error('❌ Payment failed:', err)
    } finally {
      setSending(false)
    }
  }

  return (
    <div className="send-payment">
      <h3>Send Payment</h3>

      {txid && (
        <div className="success-message">
          <p>✅ Payment sent successfully!</p>
          <p>TXID: <a href={`https://test.whatsonchain.com/tx/${txid}`} target="_blank" rel="noreferrer">{txid.substring(0, 16)}...</a></p>
        </div>
      )}

      {error && <p className="error-message">❌ {error}</p>}

      <div className="form">
        <input
          type="text"
          placeholder="Recipient Address"
          value={recipient}
          onChange={(e) => setRecipient(e.target.value)}
          disabled={sending}
        />

        <input
          type="number"
          placeholder="Amount (BSV)"
          value={amount}
          onChange={(e) => setAmount(e.target.value)}
          disabled={sending}
          step="0.00000001"
          min="0"
        />

        <button
          onClick={handleSend}
          disabled={sending || !recipient || !amount}
        >
          {sending ? 'Sending...' : 'Send Payment'}
        </button>
      </div>

      <div className="info">
        <p>The wallet will calculate the fee and request your approval.</p>
      </div>
    </div>
  )
}

Part 4: Multiple Outputs

Batch Payments

import { WalletClient, P2PKH } from '@bsv/sdk'

async function sendBatchPayment(wallet: WalletClient) {
  const result = await wallet.createAction({
    description: 'Batch payment',
    outputs: [
      {
        lockingScript: new P2PKH().lock('1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa').toHex(),
        satoshis: 1000,
        outputDescription: 'Payment 1'
      },
      {
        lockingScript: new P2PKH().lock('1BvBMSEYstWetqTFn5Au4m4GFg7xJaNVN2').toHex(),
        satoshis: 2000,

        satoshis: 3000,
        outputDescription: 'Payment 3'
      }
    ]
  })

  console.log('Batch payment sent:', result.txid)
  console.log('Total sent: 6000 satoshis to 3 recipients')

  return result.txid
}

Payment with Metadata (OP_RETURN)

import { WalletClient, P2PKH, Script } from '@bsv/sdk'

async function sendPaymentWithMetadata(
  wallet: WalletClient,
  recipientAddress: string,
  amountSatoshis: number,
  metadata: any
) {
  // Create OP_RETURN script with metadata
  const metadataHex = Buffer.from(JSON.stringify(metadata)).toString('hex')
  const opReturnScript = new Script()
  opReturnScript.writeOpCode(Script.OP_FALSE)
  opReturnScript.writeOpCode(Script.OP_RETURN)
  opReturnScript.writeBin(Buffer.from(metadataHex, 'hex'))

  const result = await wallet.createAction({
    description: 'Payment with metadata',
    outputs: [
      {
        lockingScript: new P2PKH().lock(recipientAddress).toHex(),
        satoshis: amountSatoshis,
        outputDescription: 'Payment'
      },
      {
        lockingScript: opReturnScript.toHex(),
        satoshis: 0,
        outputDescription: 'Metadata'
      }
    ]
  })

  console.log('Payment with metadata sent:', result.txid)
  return result.txid
}

// Usage

  wallet,
  '1A1zP1...',
  1000,
  {
    type: 'INVOICE_PAYMENT',
    invoiceId: 'INV-12345',
    description: 'Payment for services',
    timestamp: Date.now()
  }
)

Part 5: Message Signing

Sign and Verify Messages

import { WalletClient } from '@bsv/sdk'

async function signMessage(wallet: WalletClient, message: string) {
  try {
    // Hash the message
    const messageBytes = Buffer.from(message, 'utf8')

    // Request wallet to sign the message data
    const { signature } = await wallet.createSignature({
      data: Array.from(messageBytes),
      protocolID: [0, 'message signing'],
      keyID: '1',
      description: 'Sign message'
    })

    console.log('Message signed!')
    console.log('Message:', message)
    console.log('Signature:', Buffer.from(signature).toString('hex'))

    return signature

  } catch (error: any) {
    if (error.code === 'USER_REJECTED') {
      console.log('User rejected signing')
    } else {
      console.error('Signing failed:', error.message)
    }
    throw error
  }
}

// Usage
const signature = await signMessage(wallet, 'I agree to terms of service')

Authentication with Signatures

// components/AuthWithWallet.tsx
import React, { useState } from 'react'
import { WalletClient } from '@bsv/sdk'

interface AuthProps {
  wallet: WalletClient
  onAuthenticated: (publicKey: string, signature: Uint8Array) => void
}

export const AuthWithWallet: React.FC<AuthProps> = ({ wallet, onAuthenticated }) => {
  const [authenticating, setAuthenticating] = useState(false)

  const handleAuth = async () => {
    setAuthenticating(true)

    try {
      // Get user's identity public key
      const { publicKey } = await wallet.getPublicKey({ identityKey: true })

      // Create challenge message
      const timestamp = Date.now()
      const challenge = `Login to MyApp at ${timestamp}`
      const messageBytes = Buffer.from(challenge, 'utf8')

      // Request signature
      const { signature } = await wallet.createSignature({
        data: Array.from(messageBytes),
        protocolID: [0, 'authentication'],
        keyID: '1',
        description: 'Authenticate to MyApp'
      })

      // Send to backend for verification
      const response = await fetch('/api/auth/wallet', {
        method: 'POST',
        headers: { 'Content-Type': 'application/json' },
        body: JSON.stringify({
          publicKey,
          message: challenge,
          signature: Buffer.from(signature).toString('hex')
        })
      })

      if (response.ok) {
        const { token } = await response.json()
        localStorage.setItem('auth_token', token)
        onAuthenticated(publicKey, signature)
        console.log('✅ Authenticated with wallet')
      } else {
        throw new Error('Authentication failed')
      }

    } catch (error: any) {
      console.error('❌ Authentication failed:', error)
      alert(error.message)
    } finally {
      setAuthenticating(false)
    }
  }

  return (
    <button
      onClick={handleAuth}
      disabled={authenticating}
    >
      {authenticating ? 'Authenticating...' : 'Login with Wallet'}
    </button>
  )
}

Part 6: Error Handling

Common Error Codes

try {
  await wallet.createAction({ description: '...', outputs: [...] })
} catch (error: any) {
  switch (error.code) {
    case 'USER_REJECTED':
      // User cancelled the transaction
      console.log('User rejected transaction')
      break

    case 'INSUFFICIENT_FUNDS':
      // User doesn't have enough balance
      console.log('Insufficient funds')
      alert('You don\'t have enough BSV for this transaction')
      break

    case 'WALLET_NOT_FOUND':
      // MetaNet Desktop Wallet not installed
      console.log('Wallet not installed')
      alert('Please install MetaNet Desktop Wallet')
      break

    case 'WALLET_LOCKED':
      // Wallet is locked
      console.log('Wallet is locked')
      alert('Please unlock your wallet')
      break

    case 'NETWORK_ERROR':
      // Broadcasting failed
      console.log('Network error')
      alert('Transaction failed to broadcast. Please try again.')
      break

    case 'INVALID_OUTPUT':
      // Output format is wrong
      console.log('Invalid output')
      alert('Invalid transaction output')
      break

    default:
      console.error('Unknown error:', error)
      alert(`Transaction failed: ${error.message}`)
  }
}

Comprehensive Error Handler

function handleWalletError(error: any, context: string) {
  const errorMessages: Record<string, string> = {
    'USER_REJECTED': 'You cancelled the request',
    'INSUFFICIENT_FUNDS': 'Insufficient balance in your wallet',
    'WALLET_NOT_FOUND': 'MetaNet Desktop Wallet not installed. Please install it from desktop.bsvb.tech',
    'WALLET_LOCKED': 'Please unlock your wallet and try again',
    'NETWORK_ERROR': 'Network error. Please check your connection and try again',
    'INVALID_OUTPUT': 'Invalid transaction format',
    'TIMEOUT': 'Request timed out. Please try again'
  }

  const userMessage = errorMessages[error.code] || `${context} failed: ${error.message}`

  console.error(`❌ ${context} error:`, {
    code: error.code,
    message: error.message,
    details: error
  })

  return userMessage
}

// Usage
try {
  await wallet.sendTransaction({ outputs: [...] })
} catch (error) {
  const message = handleWalletError(error, 'Payment')
  alert(message)
}

Part 7: Best Practices

1. Always Check Connection State

function ensureWalletConnected(wallet: WalletClient | null) {
  if (!wallet) {
    throw new Error('Wallet not connected. Please connect your wallet first.')
  }
}

// Usage
async function sendPayment(wallet: WalletClient | null, recipient: string, amount: number) {
  ensureWalletConnected(wallet)
  return await wallet!.sendTransaction({ outputs: [{ address: recipient, satoshis: amount }] })
}

2. Provide Clear Transaction Previews

// Show user what they're approving BEFORE calling wallet
function TransactionPreview({ recipient, amount }: { recipient: string, amount: number }) {
  const fee = 500 // Estimated (wallet calculates actual)
  const total = amount + fee

  return (
    <div className="tx-preview">
      <h4>Transaction Preview</h4>
      <p>Recipient: {recipient}</p>
      <p>Amount: {amount} satoshis</p>
      <p>Est. Fee: ~{fee} satoshis</p>
      <p><strong>Total: ~{total} satoshis</strong></p>
      <p className="note">Final fee determined by wallet</p>
    </div>
  )
}

3. Handle User Cancellation Gracefully

async function requestPayment(wallet: WalletClient, recipient: string, amount: number) {
  try {
    const result = await wallet.sendTransaction({
      outputs: [{ address: recipient, satoshis: amount }]
    })
    return { success: true, txid: result.txid }
  } catch (error: any) {
    if (error.code === 'USER_REJECTED') {
      // Don't show error for user cancellation - it's intentional
      return { success: false, cancelled: true }
    }
    // Show error for other failures
    return { success: false, error: error.message }
  }
}

4. Provide Fallback Instructions

function WalletNotFound() {
  return (
    <div className="wallet-not-found">
      <h3>BSV Desktop Required</h3>
      <p>This dApp requires BSV Desktop (MetaNet Desktop Wallet) to function.</p>

5. Persist Connection State

// Save connection preference
useEffect(() => {
  if (walletConnected) {
    localStorage.setItem('wallet_auto_connect', 'true')
  } else {
    localStorage.removeItem('wallet_auto_connect')
  }
}, [walletConnected])

// Auto-reconnect on page load
useEffect(() => {
  const shouldAutoConnect = localStorage.getItem('wallet_auto_connect') === 'true'
  if (shouldAutoConnect) {
    connectWallet()
  }
}, [])

Part 8: Complete dApp Example

Here's a complete React dApp integrating all concepts:

// App.tsx
import React from 'react'
import { useWallet } from './hooks/useWallet'
import { WalletConnect } from './components/WalletConnect'
import { SendPayment } from './components/SendPayment'
import { TransactionHistory } from './components/TransactionHistory'
import './App.css'

function App() {
  const { wallet, publicKey, connected, error } = useWallet()

  return (
    <div className="App">
      <header>
        <h1>My BSV dApp</h1>
        <WalletConnect />
      </header>

      <main>
        {connected && wallet ? (
          <>
            <div className="user-info">
              <h2>Your Wallet</h2>
              <p>Public Key: {publicKey?.substring(0, 20)}...</p>
            </div>

            <SendPayment wallet={wallet} />

            <TransactionHistory publicKey={publicKey!} />
          </>
        ) : (
          <div className="connect-prompt">
            <h2>Welcome to My BSV dApp</h2>
            <p>Connect your MetaNet Desktop Wallet to get started</p>
            {error && <p className="error">{error}</p>}
          </div>
        )}
      </main>

      <footer>
        <p>Built with BSV SDK and WalletClient</p>

  )
}

export default App

Summary

What You Learned:

✅ WalletClient connects your dApp to MetaNet Desktop Wallet
✅ Wallet handles all key management, UTXO selection, fees, and broadcasting
✅ Your dApp requests user approval for transactions
✅ Error handling for user rejections and failures
✅ Message signing for authentication
✅ Best practices for UX and state management

What You DON'T Need to Do:

❌ Manage private keys
❌ Track UTXOs
❌ Calculate fees
❌ Create change outputs
❌ Configure ARC
❌ Handle low-level transaction details

The wallet does all of this automatically!
