# IP Asset Modifications

IP Assets can be modified/customized a few ways. For example, by [setting the License Config](/concepts/licensing-module/license-config) which allows you to change a few things as you'll see below, changing its metadata, and more. These things can **always be changed unless there is a certain condition**.

| Action                      | Conditions                                                                                                                                                                                                                            | Via The...                                                                                                                              |
| --------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------- |
| Modify License Minting Fee  | You can **increase** the minting fee. You **cannot** decrease it.                                                                                                                                                                     | [License Config](/concepts/licensing-module/license-config)                                                                             |
| Modify Licensing Hook       | The hook must be whitelisted in the [Module Registry](/concepts/registry/module-registry).                                                                                                                                            | [License Config](/concepts/licensing-module/license-config)                                                                             |
| Modify `commercialRevShare` | You can **increase** the rev share percentage. You **cannot** decrease it. <br /><br />However, you **can** set it to 0 to disable the overwrite.                                                                                     | [License Config](/concepts/licensing-module/license-config)                                                                             |
| Disable/Enable the License  | License can be disabled or re-enabled at any time.<br /><br />*Note that disabling a license disallows future licenses from being minted, but does not affect existing ones.*                                                         | [License Config](/concepts/licensing-module/license-config)                                                                             |
| Modify Metadata             | Cannot modify if the metadata is **frozen**. This is done by calling `freezeMetadata` in the [CoreMetadataModule.sol](https://github.com/storyprotocol/protocol-core-v1/blob/main/contracts/modules/metadata/CoreMetadataModule.sol). | [CoreMetadataModule.sol](https://github.com/storyprotocol/protocol-core-v1/blob/main/contracts/modules/metadata/CoreMetadataModule.sol) |

## License Hook Modifications

The IP can be further customized or modified using the [License Hook](/concepts/hooks#licensing-hooks). This is a function that gets set within the License Config that gets called before a [License Token](/concepts/licensing-module/license-token) (or more simply, a "license") is minted. There are various features you can implement with the License Hook, and are **always modifiable**:

| Feature             | Description                                                                                                         |
| ------------------- | ------------------------------------------------------------------------------------------------------------------- |
| Dynamic License Fee | You can dynamically set the price of a license. For example, it can be updated dynamically via bonding curve logic. |
| Total # of Licenses | You can abort the function based on a maximum number of license tokens that can be minted.                          |
| Specific Receivers  | You can restrict minting of license to a specific receiver.                                                         |
| More...             | Additional licensing hook features can be implemented as required.                                                  |
