## Methods

### create

▸ **create**(`opts?`: [ProcedureOpts](https://github.com/PolymathNetwork/polymesh-sdk/blob/docs/beta/docs/interfaces/procedureopts.md)): *Promise‹*[*TransactionQueue*](/polymesh-sdk-api-reference/docs-beta/classes/transactionqueue.md)*‹*[*Checkpoint*](/polymesh-sdk-api-reference/docs-beta/classes/checkpoint.md)*››*

Create a snapshot of Asset Holders and their respective balances at this moment

**`note`** this method is of type [NoArgsProcedureMethod](https://github.com/PolymathNetwork/polymesh-sdk/blob/docs/beta/docs/interfaces/noargsproceduremethod.md), which means you can call [create.checkAuthorization](https://github.com/PolymathNetwork/polymesh-sdk/blob/docs/beta/docs/interfaces/noargsproceduremethod.md#checkauthorization) on it to see whether the signing Account and Identity have the required roles and permissions to run it

**Parameters:**

| Name    | Type                                                                                                             |
| ------- | ---------------------------------------------------------------------------------------------------------------- |
| `opts?` | [ProcedureOpts](https://github.com/PolymathNetwork/polymesh-sdk/blob/docs/beta/docs/interfaces/procedureopts.md) |

**Returns:** *Promise‹*[*TransactionQueue*](/polymesh-sdk-api-reference/docs-beta/classes/transactionqueue.md)*‹*[*Checkpoint*](/polymesh-sdk-api-reference/docs-beta/classes/checkpoint.md)*››*
