# Developer - Create a Capsule Collection

Capsule Collections are NFT collections which support the minting of Capsule NFTs. You can mint any number of Simple Capsule NFTs, ERC-20 Capsule NFTs, ERC-721 Capsule NFTs, or ERC-1155 Capsule NFTs from a Capsule Collection you create.

Below is an example of creating your own Capsule Collection.

### Methodology

In order to create a Capsule Collection, only one method needs to be called - `createCapsuleCollection`. 

The docs for the method (also found under [CapsuleFactory.sol](/capsulenft/developer-walkthroughs/contracts/capsulefactory.sol.md#createcapsulecollection)) are posted here for reference:

```solidity
function createCapsuleCollection(string _name, string _symbol, address _tokenURIOwner, bool _isCollectionPrivate) external payable returns (address)
```

**Usage**: The main method which creates a Capsule NFT Collection for a user. Creation of a Capsule Collection MUST go through the CapsuleFactory in order to ensure ecosystem safety - this ensures that no Capsule contract is able to exploit the CapsuleMinter's token storing/redeeming methods.

**Parameters**:

* `_name`: (string) - the name of the Capsule Collection
* `_symbol`: (string) - the symbol of the Capsule Collection
* `_tokenURIOwner`: (address) - the address of the Capsule Collection tokenURIOwner (also known as the Metamaster)
* `_isCollectionPrivate`: (boolean) - whether the Capsule Collection is designated as private

**Returns**: (address) - The address of the newly deployed Capsule Collection.

### Example Capsule Collection Creation Call

An example call is shown here:

```
createCapsuleCollection(
    "Capsule",
    "CNFT",
    ZERO_ADDRESS,
    false,
    { value: 0.025 }
);
```

This call will create a Capsule Collection:

* Named `Capsule`
* With Symbol `CNFT`
* Whose Metamaster is the `Zero Address` (0x0000000000000000000000000000000000000000). The metamaster has control over ALL metadata in the collection. In most cases, you'd either set the Metamaster to **your address** (so that you'd have ownership over all metadata to change at any time), or the **zero address** (so that your Capsule NFTs metadata link can never be changed after mint).
* With Capsule Collection privacy boolean `false`, meaning this is a **public** Capsule Collection. A public Capsule Collection allows anyone from any address to mint Capsule NFTs within the Capsule Collection. A private Capsule Collection (`true`) only allows the `owner` to mint Capsule NFTs within the Capsule Collection.

*Note: The owner of the Capsule Collection is set to the address which calls the \`createCapsuleCollection\` method. The owner may change ownership of a Capsule Collection at any time.*

* With ETH fee amount specified. This is the [required amount to create](/economics/fee-structure.md) a Capsule Collection.
