array of Scope/Identity IDs that are exempted from the Restriction

**`note`** if the Asset requires investor uniqueness, Scope IDs are used. Otherwise, we use Identity IDs.

## Methods

### addRestriction

▸ **addRestriction**(`args`: [AddRestrictionParams](/polymesh-sdk-api-reference/docs-beta/globals.md#addrestrictionparams)‹T›, `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)*‹BigNumber››*

*Defined in* [*src/api/entities/Asset/TransferRestrictions/TransferRestrictionBase.ts:126*](https://github.com/PolymathNetwork/polymesh-sdk/blob/31a16a34/src/api/entities/Asset/TransferRestrictions/TransferRestrictionBase.ts#L126)

Add a Transfer Restriction of the corresponding type to this Asset

**`note`** the result is the total amount of restrictions after the procedure has run

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

**Parameters:**

| Name    | Type                                                                                                             |
| ------- | ---------------------------------------------------------------------------------------------------------------- |
| `args`  | [AddRestrictionParams](/polymesh-sdk-api-reference/docs-beta/globals.md#addrestrictionparams)‹T›                 |
| `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)*‹BigNumber››*

***

### get

▸ **get**(): *Promise‹*[*GetReturnType*](/polymesh-sdk-api-reference/docs-beta/globals.md#getreturntype)*‹T››*

*Defined in* [*src/api/entities/Asset/TransferRestrictions/TransferRestrictionBase.ts:161*](https://github.com/PolymathNetwork/polymesh-sdk/blob/31a16a34/src/api/entities/Asset/TransferRestrictions/TransferRestrictionBase.ts#L161)

Retrieve all active Transfer Restrictions of the corresponding type

**`note`** there is a maximum number of restrictions allowed across all types. The `availableSlots` property of the result represents how many more restrictions can be added before reaching that limit

**Returns:** *Promise‹*[*GetReturnType*](/polymesh-sdk-api-reference/docs-beta/globals.md#getreturntype)*‹T››*

***

### removeRestrictions

▸ **removeRestrictions**(`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)*‹BigNumber››*

*Defined in* [*src/api/entities/Asset/TransferRestrictions/TransferRestrictionBase.ts:150*](https://github.com/PolymathNetwork/polymesh-sdk/blob/31a16a34/src/api/entities/Asset/TransferRestrictions/TransferRestrictionBase.ts#L150)

Removes all Transfer Restrictions of the corresponding type from this Asset

**`note`** the result is the total amount of restrictions after the procedure has run

**`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 [removeRestrictions.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)*‹BigNumber››*

***

### setRestrictions

▸ **setRestrictions**(`args`: [SetRestrictionsParams](/polymesh-sdk-api-reference/docs-beta/globals.md#setrestrictionsparams)‹T›, `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)*‹BigNumber››*

*Defined in* [*src/api/entities/Asset/TransferRestrictions/TransferRestrictionBase.ts:138*](https://github.com/PolymathNetwork/polymesh-sdk/blob/31a16a34/src/api/entities/Asset/TransferRestrictions/TransferRestrictionBase.ts#L138)

Sets all Transfer Restrictions of the corresponding type on this Asset

**`note`** the result is the total amount of restrictions after the procedure has run

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

**Parameters:**

| Name    | Type                                                                                                             |
