The NFT owner is the owner of the base-IP and is therefore at the highest level. The NFT owner can perform any action or assign any role but crucially, the NFT owner is the only one who can assign the manager role. Upon deployment or transfer of the data NFT, the NFT owner is automatically added as a manager. The NFT owner is also the only role that can’t be assigned to multiple users — the only way to share this role is via multi-sig or a DAO.

Alternatively, for a more straightforward solution that doesn't require coding, you can utilize the network explorer of your asset's network. By accessing the network explorer, you can directly interact with the contracts associated with your asset. Below, we provide a few examples to help guide you through the process.

#### Manager

### Manager
|
||||
|
||||
The ability to add or remove Managers is exclusive to the **NFT Owner**. If you are the NFT Owner and wish to add/remove a new manager, simply call the [addManager](https://github.com/oceanprotocol/contracts/blob/9e29194d910f28a4f0ef17ce6dc8a70741f63309/contracts/templates/ERC721Template.sol#L426)/[removeManager](https://github.com/oceanprotocol/contracts/blob/9e29194d910f28a4f0ef17ce6dc8a70741f63309/contracts/templates/ERC721Template.sol#L438) function within the ERC721Template contract. This function enables you to grant managerial permissions to the designated individual.

||||
#### ERC20 Deployer
|
||||
|
||||
The Deployer has a bunch of privileges at the ERC20 datatoken level. They can deploy new datatokens with fixed price exchange, or free pricing. They can also update the ERC725Y key-value store and **assign** **roles** at the ERC20 level(datatoken level).
|
||||
|
||||
To add/remove an ERC20 deployer, the manager can use the [addToCreateERC20List](https://github.com/oceanprotocol/contracts/blob/9e29194d910f28a4f0ef17ce6dc8a70741f63309/contracts/utils/ERC721RolesAddress.sol#L111)/[removeFromCreateERC20List](https://github.com/oceanprotocol/contracts/blob/9e29194d910f28a4f0ef17ce6dc8a70741f63309/contracts/utils/ERC721RolesAddress.sol#L129) functions from the ERC721RolesAddress.

||||
### Metadata Updater
|
||||

There is also a specific role for updating the metadata. The [Metadata](../metadata.md) updater has the ability to update the information about the data asset (title, description, sample data etc) that is displayed to the user on the asset detail page within the market.

### Store Updater

The store updater can store, remove or update any arbitrary key value using the ERC725Y implementation (at the ERC721 level). The use case for this role depends a lot on what data is being stored in the ERC725Y key-value pair — as mentioned above, this is highly flexible.
