### Methods

#### add

▸ **add**(`args`, `opts?`): `Promise`<`TransactionQueue`<[`Asset`](https://developers.polymath.network/polymesh-sdk-api-reference/docs-alpha/classes/api_entities_asset.asset), [`Asset`](https://developers.polymath.network/polymesh-sdk-api-reference/docs-alpha/classes/api_entities_asset.asset), `unknown`\[]\[]>>

Add a new compliance requirement to the the Asset. This doesn't modify existing requirements

**`note`** this method is of type [ProcedureMethod](https://developers.polymath.network/polymesh-sdk-api-reference/docs-alpha/interfaces/types.proceduremethod), which means you can call [add.checkAuthorization](https://developers.polymath.network/polymesh-sdk-api-reference/docs-alpha/interfaces/types.proceduremethod#checkauthorization) on it to see whether the signing Account and Identity have the required roles and permissions to run it
