## Properties

### `Protected` context

• **context**: [*Context*](/polymesh-sdk-api-reference/docs-v4/classes/context.md)

*Inherited from void*

*Defined in* [*src/api/entities/Namespace.ts:11*](https://github.com/PolymathNetwork/polymesh-sdk/blob/a0872cf4/src/api/entities/Namespace.ts#L11)

### `Protected` parent

• **parent**: [*SecurityToken*](/polymesh-sdk-api-reference/docs-v4/classes/securitytoken.md)

*Inherited from void*

*Defined in* [*src/api/entities/Namespace.ts:9*](https://github.com/PolymathNetwork/polymesh-sdk/blob/a0872cf4/src/api/entities/Namespace.ts#L9)

### pause

• **pause**: *ProcedureMethod‹void,* [*SecurityToken*](/polymesh-sdk-api-reference/docs-v4/classes/securitytoken.md)*›*

*Defined in* [*src/api/entities/SecurityToken/Compliance/Requirements.ts:160*](https://github.com/PolymathNetwork/polymesh-sdk/blob/a0872cf4/src/api/entities/SecurityToken/Compliance/Requirements.ts#L160)

Pause all the Security Token's requirements. This means that all transfers will be allowed until requirements are unpaused

**`note`** required role:

* Security Token Owner

### reset

• **reset**: *ProcedureMethod‹void,* [*SecurityToken*](/polymesh-sdk-api-reference/docs-v4/classes/securitytoken.md)*›*

*Defined in* [*src/api/entities/SecurityToken/Compliance/Requirements.ts:152*](https://github.com/PolymathNetwork/polymesh-sdk/blob/a0872cf4/src/api/entities/SecurityToken/Compliance/Requirements.ts#L152)

Detele all the current requirements for the Security Token.

**`note`** required role:

* Security Token Owner

### set

• **set**: *ProcedureMethod‹*[*SetAssetRequirementsParams*](/polymesh-sdk-api-reference/docs-v4/interfaces/setassetrequirementsparams.md)*,* [*SecurityToken*](/polymesh-sdk-api-reference/docs-v4/classes/securitytoken.md)*›*

*Defined in* [*src/api/entities/SecurityToken/Compliance/Requirements.ts:68*](https://github.com/PolymathNetwork/polymesh-sdk/blob/a0872cf4/src/api/entities/SecurityToken/Compliance/Requirements.ts#L68)

Configure asset compliance requirements for the Security Token. This operation will replace all existing requirements with a new requirement set

This requires two transactions

**`param`** array of array of conditions. For a transfer to be successful, it must comply with all the conditions of at least one of the arrays. In other words, higher level arrays are *OR* between them, while conditions inside each array are *AND* between them

**`example`** Say A, B, C, D and E are requirements and we arrange them as `[[A, B], [C, D], [E]]`. For a transfer to succeed, it must either comply with A AND B, C AND D, OR E.

**`note`** required role:

* Security Token Owner

### unpause

• **unpause**: *ProcedureMethod‹void,* [*SecurityToken*](/polymesh-sdk-api-reference/docs-v4/classes/securitytoken.md)*›*

*Defined in* [*src/api/entities/SecurityToken/Compliance/Requirements.ts:165*](https://github.com/PolymathNetwork/polymesh-sdk/blob/a0872cf4/src/api/entities/SecurityToken/Compliance/Requirements.ts#L165)

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://developers.polymath.network/polymesh-sdk-api-reference/docs-v4/classes/requirements.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
