## Avatars

{% tabs %}
{% tab title="About Avatars" %}
Avatars are a set of voxel assets that are playable in game which:

* Respect a template for compatibility with equipment that players can apply to their avatrs in order to change appearance and stats
* Respect hundreds of gaming animations and have 3D attributes to interact in Experiences (run, crawl, swim, etc.)
* Can trigger emotes and dances for socializing and for collaborative objectives

There are two types of Avatars you can own, which are seamlessly available for purchase on [**The Marketplace**](https://www.sandbox.game/en/shop/) and via your [**Avatar page**](https://www.sandbox.game/en/me/avatar/):

## Assets

### Entities & Equipment

{% tabs %}
{% tab title="About" %}
Assets include entities that populate Experiences with 3D interactive content and equipment that players can apply to their avatars with potential to modify their player stats and appearance. Entities and Equipment are [**created in VoxEdit**](https://app.gitbook.com/s/83PS3g9zpWmq73xzlwFn/voxedit/create-assets), along with the terrain blocks that shape an Experience.

Assets can be minted as ERC-1155 tokens so they can be bought, sold, traded, and used in the metaverse by their owners.

Some assets are not NFTs. There is no need to mint an asset if you create it and use it in an Experience of your own.

Owning an asset can empower you in a number of ways depending on what it is and how it was designed and minted:

{% tab title="Your Workspace" %}

### Your Workspace

Log in to your account and view your [**Workspace**](https://docs.sandbox.game/en/accounts/manage/info-and-tools#workspace) to see the assets uploaded to your Workspace.

To view NFT assets you own, visit your [**Wallet**](https://www.sandbox.game/en/me/wallet/).

{% tab title="About ERC-1155 Tokens" %}
{% hint style="info" %}
Key Attributes of ERC-1155 token standard includes:

* multi-token management with a single contract to simplify contract interactions, reduce deployment costs, and reduce blockchain bloat and associated costs
* supporting both fungible and non-fungible tokens for versatility with applications
* batch transfers of multiple tokens in a single transaction to streamline operations and reduce gas costs
* atomic swaps to enhance security and reduce risks associated with multi-step transactions
  {% endhint %}

## Catalysts

{% hint style="info" %}
Gems are no longer needed to mint Assets, only Catalysts!
{% endhint %}

{% tabs %}
{% tab title="About" %}
Catalysts are NFTs that are burned during the process of [**minting an asset**](https://app.gitbook.com/s/83PS3g9zpWmq73xzlwFn/voxedit/mint-assets-sell-nfts). They set the asset's rarity, making it more valuable as an NFT.

The more rare the Catalyst, the more Attribute Points there are available to apply toward Power, Defense, or Speed on equipment assets.

{% hint style="warning" %}
Non-equipment assets require Catalysts to mint, however, they don’t have Attribute Points as they can’t be equipped by the Avatar. The team is working on designing systems in which the Catalysts can add more value to these assets.
{% endhint %}

### Catalyst Tiers

There are five Catalyst tiers:

* Legendary (the most scarce)
* Epic
* Rare
* Uncommon
* Common (the least scarce)

### Do I Need to Mint My Assets to Launch My Own Experience?

{% hint style="info" %}
No. You do not need to mint assets you have created as NFTs in order to use them in your own Experiences. Simply upload an asset to your Workspace, set the rarity by choosing a Catalyst, and create the Attributes needed for your gameplay. Upload a few versions of your asset with different Attributes and test in Game Maker if needed.

## Experiences, or Games

While an Experience is not technically an NFT, it is owned by its creator and can be transferred to others, including its assets, from your account inventory.

Though there is currently no built in method to monetise transferring an Experience to another user for payment in SAND, you can make a private arrangement with another party.

It is highly recommended to review our security documentation about private exchanges:
