const cluster = await clusters.getRegistrationTransactionSolana(names, sender);
```

**Response**

{% hint style="warning" %}
Notice when using solana, `transactionData` is an array of transactions instead of a single object on other networks. This is because only one name is supported per transaction at the moment when using solana.

### getTransactionStatus(tx)

Get the status of a specific transaction hash.

{% hint style="info" %}
For now, if you registered more than one name in a transaction, it'll only give you the status of the first name.
{% endhint %}

**Example**

```javascript
const cluster = await clusters.getTransactionStatus("0xffea3b29c64016772b7d3194b3c3899a62191e654990b6e3393b410667102284");
```

**Response**

```typescript
type status = 'not_found' | 'pending' | 'invalid' | 'finalized'
```

{% tabs %}
{% tab title="200" %}

```json
{
  "tx": "0xffea3b29c64016772b7d3194b3c3899a62191e654990b6e3393b410667102284",
