# Integrate Embedded Wallets with the Solana Blockchain in React Native

While using the Web3Auth React Native SDK, you get a native Solana provider that can be used with [@solana/web3.js](https://solana.com/docs/clients/official/javascript#solana-web3js). Use it to get accounts, balances, sign and send transactions, and sign messages.

## Installation[​](#installation "Direct link to Installation")

To interact with the Solana blockchain in React Native, you can use [@solana/web3.js](https://solana.com/docs/clients/official/javascript#solana-web3js) library with Web3Auth along with `@web3auth/solana-provider` package.

- npm
- Yarn
- pnpm
- Bun

```
npm install --save @solana/web3.js @web3auth/solana-provider

```

```
yarn add @solana/web3.js @web3auth/solana-provider

```

```
pnpm add @solana/web3.js @web3auth/solana-provider

```

```
bun add @solana/web3.js @web3auth/solana-provider

```

## Initializing provider[​](#initializing-provider "Direct link to Initializing provider")

Using `solana` as `chainNamespace` while initializing `web3auth` will provide a Solana provider as **`web3auth.provider`** after successful authentication.

### Getting the chainConfig[​](#getting-the-chainconfig "Direct link to Getting the chainConfig")

```
import { getSolanaChainConfig } from '@web3auth/base'

const chainConfig = getSolanaChainConfig(1, 'your_web3auth_client_id') // For Mainnet
// const chainConfig = getSolanaChainConfig(2, 'your_web3auth_client_id') // For Testnet
// const chainConfig = getSolanaChainConfig(3, 'your_web3auth_client_id') // For Devnet

```

## Initialize[​](#initialize "Direct link to Initialize")

```
import { Web3Auth, WEB3AUTH_NETWORK, CHAIN_NAMESPACES } from '@web3auth/react-native-sdk'
import { SolanaWallet } from '@web3auth/solana-provider'

const web3auth = new Web3Auth(WebBrowser, EncryptedStorage, {
  clientId: 'YOUR_WEB3AUTH_CLIENT_ID',
  network: WEB3AUTH_NETWORK.SAPPHIRE_MAINNET,
  chainConfig: {
    chainNamespace: CHAIN_NAMESPACES.SOLANA,
    chainId: '0x1', // Use 0x1 for Mainnet, 0x2 for Testnet, 0x3 for Devnet
    rpcTarget: 'https://api.mainnet-beta.solana.com',
  },
})

await web3auth.init()
await web3auth.login()

// Initialize Solana Wallet
const solanaWallet = new SolanaWallet(web3auth.provider)

```

## Get accounts[​](#get-accounts "Direct link to Get accounts")

```
import { SolanaWallet } from '@web3auth/solana-provider'

const solanaWallet = new SolanaWallet(web3auth.provider)

// Get user's Solana public address
const accounts = await solanaWallet.requestAccounts()
console.log('Solana accounts', accounts)

```

## Get balance[​](#get-balance "Direct link to Get balance")

```
import { Connection, PublicKey, LAMPORTS_PER_SOL } from '@solana/web3.js'

const solanaWallet = new SolanaWallet(web3auth.provider)

// Get connection config
const connectionConfig = await solanaWallet.request({
  method: 'solana_provider_config',
  params: [],
})

const connection = new Connection(connectionConfig.rpcTarget)

// Get accounts
const accounts = await solanaWallet.requestAccounts()

// Fetch the balance for the specified public key
const balance = await connection.getBalance(new PublicKey(accounts[0]))
const balanceInSOL = balance / LAMPORTS_PER_SOL
console.log(`Balance: ${balanceInSOL} SOL`)

```

## Sign a transaction[​](#sign-a-transaction "Direct link to Sign a transaction")

```
import {
  Connection,
  PublicKey,
  Transaction,
  SystemProgram,
  LAMPORTS_PER_SOL,
} from '@solana/web3.js'

const solanaWallet = new SolanaWallet(web3auth.provider)

// Get connection config
const connectionConfig = await solanaWallet.request({
  method: 'solana_provider_config',
  params: [],
})

const connection = new Connection(connectionConfig.rpcTarget)
const accounts = await solanaWallet.requestAccounts()
const { blockhash } = await connection.getRecentBlockhash('finalized')

// Create a transfer transaction
const transaction = new Transaction({
  recentBlockhash: blockhash,
  feePayer: new PublicKey(accounts[0]),
}).add(
  SystemProgram.transfer({
    fromPubkey: new PublicKey(accounts[0]),
    toPubkey: new PublicKey(accounts[0]), // Self transfer for demo
    lamports: 0.01 * LAMPORTS_PER_SOL,
  })
)

// Sign the transaction
const signedTransaction = await solanaWallet.signTransaction(transaction)
console.log('Signed transaction', signedTransaction)

```

## Send transaction[​](#send-transaction "Direct link to Send transaction")

```
import {
  Connection,
  PublicKey,
  Transaction,
  SystemProgram,
  LAMPORTS_PER_SOL,
} from '@solana/web3.js'

const solanaWallet = new SolanaWallet(web3auth.provider)

// Get connection config
const connectionConfig = await solanaWallet.request({
  method: 'solana_provider_config',
  params: [],
})

const connection = new Connection(connectionConfig.rpcTarget)
const accounts = await solanaWallet.requestAccounts()
const block = await connection.getLatestBlockhash('finalized')

// Create a transfer transaction
const transaction = new Transaction({
  blockhash: block.blockhash,
  lastValidBlockHeight: block.lastValidBlockHeight,
  feePayer: new PublicKey(accounts[0]),
}).add(
  SystemProgram.transfer({
    fromPubkey: new PublicKey(accounts[0]),
    toPubkey: new PublicKey(accounts[0]), // Self transfer for demo
    lamports: 0.01 * LAMPORTS_PER_SOL,
  })
)

// Sign and send the transaction
const { signature } = await solanaWallet.signAndSendTransaction(transaction)
console.log('Transaction signature', signature)

```

## Sign a message[​](#sign-a-message "Direct link to Sign a message")

```
const solanaWallet = new SolanaWallet(web3auth.provider)

// Create message to sign
const message = new TextEncoder().encode('Hello Solana from React Native!')

// Sign the message
const signedMessage = await solanaWallet.signMessage(message)
console.log('Signed message', signedMessage)

```
