# Integrate Embedded Wallets with the Solana Blockchain in Vue

While using the Web3Auth Vue SDK, you get access to native Solana composables. Pair them with [@solana/kit](https://www.npmjs.com/package/@solana/kit) for transaction building, program interactions, and account queries.

## Vue Solana integration[​](#vue-solana-integration "Direct link to Vue Solana integration")

Install `@solana/kit` and `@solana-program/system` to build and sign Solana transactions with the Embedded Wallets Vue SDK.

info

Web3Auth provides Vue composables for common Solana wallet operations. Import them from `@web3auth/modal/vue/solana`.

- npm
- Yarn
- pnpm
- Bun

```
npm install @solana/kit @solana-program/system

```

```
yarn add @solana/kit @solana-program/system

```

```
pnpm add @solana/kit @solana-program/system

```

```
bun add @solana/kit @solana-program/system

```

## Solana composables[​](#solana-composables "Direct link to 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 accounts, RPC client, and wallet. |
