# Sui Provider (Beta)

The Tomo Telegram SDK provides the SUI provider for getting addresses, signing, and sending transactions. 

```typescript
// get provider 
const sui= window.tomo_sui;
```

## Connect with the Wallet[​](https://docs.uxuy.com/uxuy-connect/guide/#isconnected) <a href="#isconnected" id="isconnected"></a>

Before using the provider, the user needs to log in to the wallet through the modal by following the method:

```typescript
// connect wallet
await sui?.connectWallet();
```

## Query Address

You can get the address of the user by one cal

```typescript
const address = sui.getAddress();
```

## Signing Methods

In Solana providers, we provide three signing methods:

* `signMessage`
* `signTransaction`
* `signAndExecuteTransaction`

### Sign message

`signMessage` method will create a simple signed transaction for one message and return the signed transaction in hex.

```typescript
 const response = await sui.signMessage(signMsg);
```

### Sign transaction

`signTransaction` supports signing arbitrary PTB transactions if they are well formed. Please check [this ](https://docs.sui.io/guides/developer/sui-101/building-ptb)for the general construction of transactions. We provide two examples:

<pre class="language-typescript"><code class="lang-typescript"><strong>// define transaction body
</strong><strong>export const getSendSuiCoinTx = async ({
</strong>  fromAddress,
  toAddress,
  amount,
  coinType,
}: {
  fromAddress: string;
  toAddress: string;
  amount: string;
  coinType?: string;
}): Promise&#x3C;{ transaction: string; bytes: Uint8Array } | null> => {
  const suiClient = getSuiClient();
  const txb = new Transaction();
  
  txb.transferObjects(
    [coinWithBalance({ balance: Number(amount), type: coinType || undefined })],
    toAddress
  );
  
  try {
    txb.setSender(fromAddress);
    const transaction = (await txb.toJSON({ client: suiClient })).toString();
    const bytes = await txb.build({ client: suiClient });
    console.log('bytes', transaction, bytes);
    return { transaction, bytes };
  } catch (e) {
    console.warn(e);
    return null;
  }
};

// create transaction body for concrete transaction
const res = await getSendSuiCoinTx({
  fromAddress: addr,
  toAddress: toAddr2,
  amount: +toValue2 * 10 ** 6 + '',
  coinType: contractAddr,
});

// create transaction
const { transaction, bytes } = res || {};

const input = {
  transactionBlock: transaction,
  chain: 'sui:mainnet',
  txBytes: bytes,
  options: {
    showEffects: true,
  },
};

// sign transaction
const signed transaction= await sui.signTransaction(input);

// or you can use sign and send transaction at the same time

const res = await sui.signAndExecuteTransaction(input);
</code></pre>

After signing the transaction, you can send it to your client or add other signatures. In addition, you can use `signAndExecuteTransaction` the method to send the signed transaction directly.
