# Checking TON Wallet Account Type

# Checking TON Wallet Account Type

When working with multiple blockchain types, you may need to check if a wallet account is specifically a TON wallet account. The `isTonWalletAccount` type guard function helps you narrow down the type safely.

## Usage

```javascript theme={"system"}
import { isTonWalletAccount } from '@dynamic-labs-sdk/ton';
import { getPrimaryWalletAccount } from '@dynamic-labs-sdk/client';

const walletAccount = getPrimaryWalletAccount();

if (walletAccount && isTonWalletAccount(walletAccount)) {
  // walletAccount is now typed as TonWalletAccount
  console.log('TON address:', walletAccount.address);
}
```

## Parameters

| Parameter       | Type            | Description                 |
| --------------- | --------------- | --------------------------- |
| `walletAccount` | `WalletAccount` | The wallet account to check |

## Returns

`boolean` - Returns `true` if the wallet account is a TON wallet account, `false` otherwise. Also acts as a TypeScript type guard, narrowing the type to `TonWalletAccount`.
