# Integrate Embedded Wallets with the Solana Blockchain in Vue

> Integrate Embedded Wallets with the Solana Blockchain in Vue | Embedded Wallets

While using the Web3Auth Vue SDK, you get access to native Solana composables. Pair them with [`@solana/web3.js`](https://solana.com/docs/clients/official/javascript#solana-web3js) for advanced features such as transaction building, program interactions, and account queries.

## Vue Solana integration

You need to install the `@solana/web3.js` package to interact with the Solana blockchain using the Web3Auth Vue composables.

:::info

Web3Auth provides a set of Vue composables for basic Solana wallet operations. These composables are designed to simplify common Solana interactions in your Vue app.

For advanced Solana features, you should use [`@solana/web3.js`](https://solana.com/docs/clients/official/javascript#solana-web3js) on top of the composables provided.

:::

```bash npm2yarn
npm install @solana/web3.js
```

## Solana composables

| Composable Name             | Description                                  |
| --------------------------- | -------------------------------------------- |
| `useSignAndSendTransaction` | Sign and send a Solana transaction.          |
| `useSignMessage`            | Sign a message with the Solana wallet.       |
| `useSignTransaction`        | Sign a Solana transaction (without sending). |
| `useSolanaWallet`           | Access Solana wallet state and utilities.    |

## Composable usage examples

### Get Solana wallet

```vue
<template>
  
    Solana Wallet
    Connected: {{ connected ? 'Yes' : 'No' }}
    Address: {{ address }}
  
</template>

<script setup>

  const { address, connected } = useSolanaWallet()
</script>
```

### Sign a message

```vue
<template>
  
    Sign Message
    <button @click="handleSignMessage" :disabled="isPending">
      {{ isPending ? 'Signing...' : 'Sign Message' }}
    </button>
    Error: {{ error.message }}
  
</template>

<script setup>

  const { signMessage, isPending, error } = useSignMessage()

  const handleSignMessage = async () => {
    try {
      const message = new TextEncoder().encode('Hello Solana!')
      const signature = await signMessage(message)
      console.log('Signature:', signature)
    } catch (err) {
      console.error('Error signing message:', err)
    }
  }
</script>
```

### Sign a transaction

```vue
<template>
  
    Sign Transaction
    <button @click="handleSignTransaction" :disabled="isPending">
      {{ isPending ? 'Signing...' : 'Sign Transaction' }}
    </button>
    Error: {{ error.message }}
  
</template>

<script setup>

  const { signTransaction, isPending, error } = useSignTransaction()

  const handleSignTransaction = async () => {
    try {
      // Create a simple transfer transaction
      const transaction = new Transaction().add(
        SystemProgram.transfer({
          fromPubkey: new PublicKey('YOUR_PUBLIC_KEY'),
          toPubkey: new PublicKey('DESTINATION_PUBLIC_KEY'),
          lamports: 0.01 * LAMPORTS_PER_SOL,
        })
      )

      const signedTransaction = await signTransaction(transaction)
      console.log('Signed Transaction:', signedTransaction)
    } catch (err) {
      console.error('Error signing transaction:', err)
    }
  }
</script>
```

### Sign and Send Transaction

```vue
<template>
  
    Sign and Send Transaction
    <button @click="handleSignAndSend" :disabled="isPending">
      {{ isPending ? 'Processing...' : 'Sign and Send' }}
    </button>
    Error: {{ error.message }}
  
</template>

<script setup>

  const { signAndSendTransaction, isPending, error } = useSignAndSendTransaction()

  const handleSignAndSend = async () => {
    try {
      // Create a simple transfer transaction
      const transaction = new Transaction().add(
        SystemProgram.transfer({
          fromPubkey: new PublicKey('YOUR_PUBLIC_KEY'),
          toPubkey: new PublicKey('DESTINATION_PUBLIC_KEY'),
          lamports: 0.01 * LAMPORTS_PER_SOL,
        })
      )

      const signature = await signAndSendTransaction(transaction)
      console.log('Transaction Signature:', signature)
    } catch (err) {
      console.error('Error signing and sending transaction:', err)
    }
  }
</script>
```

Further code and advanced usage should be implemented using Solana's web3.js library as needed.
