# getCreateDataSetResult

> **getCreateDataSetResult**(`client`, `options`): [`Promise`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise)\<[`OutputType`](/reference/filoz/synapse-core/warm-storage/namespaces/getcreatedatasetresult/type-aliases/outputtype/)\>

Defined in: [packages/synapse-core/src/warm-storage/submission-result.ts:127](https://github.com/FilOzone/synapse-sdk/blob/56f1ef3fb5ccfea19fb80cb59e997e381f37d85a/packages/synapse-core/src/warm-storage/submission-result.ts#L127)

Check on chain whether a create data set submission landed, without the SP or any transaction hash.

FWSS records each used client data set ID, so this works whichever transaction carried the call.
If `created` is false, resubmitting the same `extraData` is safe: FWSS rejects a reused client
data set ID, so a second data set can never be created from it.

## Parameters

| Parameter | Type | Description |
| ------ | ------ | ------ |
| `client` | `Client`\<`Transport`, `Chain`\> | The client to use to read the nonce. |
| `options` | [`OptionsType`](/reference/filoz/synapse-core/warm-storage/namespaces/getcreatedatasetresult/type-aliases/optionstype/) | [getCreateDataSetResult.OptionsType](/reference/filoz/synapse-core/warm-storage/namespaces/getcreatedatasetresult/type-aliases/optionstype/) |

## Returns

[`Promise`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise)\<[`OutputType`](/reference/filoz/synapse-core/warm-storage/namespaces/getcreatedatasetresult/type-aliases/outputtype/)\>

The result [getCreateDataSetResult.OutputType](/reference/filoz/synapse-core/warm-storage/namespaces/getcreatedatasetresult/type-aliases/outputtype/)

## Throws

Errors [getCreateDataSetResult.ErrorType](/reference/filoz/synapse-core/warm-storage/namespaces/getcreatedatasetresult/type-aliases/errortype/)

## Example

```ts
import { getCreateDataSetResult } from '@filoz/synapse-core/warm-storage'
import { createPublicClient, http } from 'viem'
import { calibration } from '@filoz/synapse-core/chains'

const client = createPublicClient({
  chain: calibration,
  transport: http(),
})

// `extraData` was persisted from `createDataSet` before a crash
const result = await getCreateDataSetResult(client, { extraData: '0x...' })

if (result.created) {
  console.log(result.dataSetId)
}
```
