# getwalletinformation - TON

This method returns wallet-specific information for a TON address. It identifies the wallet type, returns the current seqno (used as a nonce), wallet ID, and the last transaction. Use this method to prepare outgoing transactions from a wallet contract.

## Parameters

| Parameter | Type    | Required | Description                                                            |

| address   | string  | Yes      | Wallet address in any form                                             |
| seqno     | integer | No       | Masterchain seqno at which to read state. Defaults to the latest block |

| result.wallet                | boolean | Whether the contract is a recognised wallet                            |
| result.wallet\_type          | string  | Identifier of the wallet version (e.g. `wallet v4 r2`, `wallet v3 r2`) |
| result.seqno                 | integer | Current wallet seqno — use as the nonce for the next outgoing message  |
| result.wallet\_id            | integer | Subwallet identifier for the wallet contract                           |
| result.balance               | string  | Wallet balance in nanotons                                             |

## Use Cases

* Preparing a transfer by reading the current wallet seqno
* Detecting wallet version to build a compatible message body
* Wallet application UX that displays type and version
* Validating that a destination is an initialised wallet before depositing

## Error Handling

| Status Code | Error Message       | Cause                                       |

## SDK Integration

{% tabs %}
{% tab title="@ton/ton (JavaScript)" %}

```javascript
import { TonClient } from '@ton/ton';

const client = new TonClient({
    endpoint: 'https://go.getblock.io/<ACCESS-TOKEN>/'
});

// The @ton/ton client wraps the same JSON-RPC methods.
// For low-level access, use client.callGetMethod or client.provider.
```

{% endtab %}

{% tab title="pytoniq (Python)" %}

```python
from pytoniq import LiteClient
# For HTTP API access, use ton-http-client or call the JSON-RPC
# endpoint directly with requests as shown in the Request Example.
```

{% endtab %}
{% endtabs %}
