# Integrate Embedded Wallets with the Sui Blockchain

While using the Embedded Wallets Web SDK (formerly Web3Auth) for a non-EVM chain like [Sui](https://sui.io/), you can get the user's private key from the provider. Using this private key, you can use the corresponding libraries of the blockchain to make blockchain calls like getting the user's public `signing key`, fetching `balance`, and `sign & send transaction`. We have highlighted a few methods here to get you started quickly.

note

The SDKs are now branded as MetaMask Embedded Wallet SDKs (formerly Web3Auth Plug and Play SDKs). Package names and APIs remain Web3Auth (for example, Web3Auth React SDK), and code snippets may reference `web3auth` identifiers.

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

For Sui, we will use the [@mysten/sui.js](https://www.npmjs.com/package/@mysten/sui.js) library to create the Sui address, query the chain and submit transactions.

- npm
- Yarn
- pnpm
- Bun

```
npm install --save @mysten/sui.js

```

```
yarn add @mysten/sui.js

```

```
pnpm add @mysten/sui.js

```

```
bun add @mysten/sui.js

```

## Get account and keypair[​](#get-account-and-keypair "Direct link to Get account and keypair")

Once a user logs in, the Embedded Wallets SDK returns a provider. Since there isn't a native provider for Sui, we directly use the private key to create the account.

Using the function, `web3auth.provider.request({method: "private_key"})` from Web3Auth provider, the application can have access to the user's private key. However, Web3Auth does not provide direct access to Sui specific signing functions, hence, we create a new `Ed25519Keypair` to give SDK the ability to sign transactions with this key pair.

```
import { Ed25519Keypair } from '@mysten/sui.js/keypairs/ed25519'

// web3authProvider is web3auth.provider from above
const privateKey = await web3authProvider.request({ method: 'private_key' })

// Create a Uint8Arrray from private key which is in hex format
const privateKeyUint8Array = new Uint8Array(
  privateKey.match(/.{1,2}/g)!.map((byte: any) => parseInt(byte, 16))
)

// Create an instance of the Sui local key pair manager
const keyPair = Ed25519Keypair.fromSecretKey(privateKeyUint8Array)

const address = keyPair.toSuiAddress()
console.log(`Sui account: ${address}`)

```

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

```
import { CoinBalance, getFullnodeUrl, SuiClient } from '@mysten/sui.js/client';
import { MIST_PER_SUI } from '@mysten/sui.js/utils';

// Use the getFullnodeUrl from SDK to get the RPC detils for the Sui network.
const rpcUrl = getFullnodeUrl('devnet');
const suiClient = new SuiClient({ url: this.rpcUrl });

// Use code from the above to retrive address here.
const balanceResponse = await this.suiClient.getBalance({owner: address});
const suiBalance = balance(balanceResponse);
console.log(`Sui Balance: ${suiBalance}`);


// Convert MIST to Sui
private balance = (balance: CoinBalance) => {
    return Number.parseInt(balance.totalBalance) / Number(MIST_PER_SUI);
}

```

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

```
import { TransactionBlock } from '@mysten/sui.js/transactions'
import { MIST_PER_SUI } from '@mysten/sui.js/utils'

// Use code from the above Initializing SuiClient and Ed25519Keypair here

const tx = new TransactionBlock()

// Convert value to be transferred to smallest value.
const [coin] = tx.splitCoins(tx.gas, [tx.pure(0.2 * Number(MIST_PER_SUI))])
tx.transferObjects(
  [coin],
  tx.pure('0x7d42ef777fa6e46a7b19d54dc9353c898e7f1c65a3abab8b73f92fe5efe6d96d')
)

const result = await this.suiClient.signAndExecuteTransactionBlock({
  signer: keyPair,
  transactionBlock: tx,
})
const transactionHash = result.digest
console.log(`Transaction hash: ${transactionHash}`)

```
