A Catalyst is a special NFT burned when you mint an asset as an NFT. It defines the asset's rarity. Select a Catalyst when you Upload Assets to Workspaces. Edit anytime before minting.

One Catalyst is burned to create one Asset
Rarity & Attributes
A Catalyst with greater rarity has more Attribute Points to apply to an equipment asset for Power, Defense, or Speed. These Attributes make gameplay more exciting for players.
Assigning Attribute Points when creating a new equipment asset based on the rarity of the Catalyst
The team is working on a system in which Catalysts can add value to non-equipment assets, which still require a Catalyst to mint, but do not have Attribute Points.
Purchasing Catalysts
Catalysts are newly released and in limited supply, which will gradually increase.
An NFT drop is group of NFTs to be listed on the Marketplace at the same time and in a specific ratio depending on your strategy. This could be aligned with the launch of an Experience or assets sold independently by an artist.
Passes are a different class of NFT that can be required for players to access an Experience (see Access Restrictions). Generally, equipment is best if you plan to use valuable CATALYST NFTs to mint these, but most can be common so you can mint more copies at a lower cost.
You can also limit access to certain gameplay in an Experience using the NFT Sensor. One or more assets from your NFT Drop could be required to access exclusive areas, unlock special player perks, etc.
The following tabs share some recommended NFT Drop ratios that may work for you and suggestions to create your marketing materials.
Larger NFT drops are not recommended to ensure they are more likely to sell out.

Export Assets & Begin Renders
Why Export?
The camera button in the bottom left of VoxEdit's modules creates a nice image with a transparent background if you're a beginner.
However, whether you plan to sell an asset as an NFT or just promote your Experience, you likely want more options such as a higher resolution image, flexible lighting, a custom background, still asset rotation (GIF), asset animations demonstrated (GIF), etc.
Experts also import assets into third-party motion design software to make Experience trailers.
How to Export?
Open an asset, choose Export from VoxEdit's File menu, and choose the format needed.
RECOMMENDED THIRD-PARTY SOFTWARE
Note: Assets with long animations or higher quality settings take longer to render.
Make sure the background colours and composition of rendered images are cohesive.
Non-Minted Assets
Uploaded assets have migrated to new equivalent Catalysts. You can edit them before minting.
Equipment
Only equipment assets will have their Gems converted to Attribute Points:
Magic -> Defense
Luck -> Speed
Non-Equipment
The team is working on a system in which Catalysts can add value to non-equipment assets, which still require a Catalyst to mint, but do not have Attribute Points.
Royalties
NEW ROYALTIES SYSTEM
The price of an NFT is set by the seller.
If the seller minted (created) the NFT, they receive the full sale price.
If the seller did not mint the asset (reselling):
The seller receives 95% of the sale price
The minter (creator) receives 2.5% of the sale price
The Sandbox receives 2.5% of the sale price. This supplies The Sandbox Foundation with SAND to distribute among the Game Maker Fund, staking, and rewards.
The Sandbox Marketplace will ensure fair secondary market royalty rewards for all creators building in The Sandbox.
This in house mechanism will be compatible with marketplaces that implement the ERC-2981 standard. Royalties distributed by external marketplaces will be accessible later in 2024.
Minting Process
Get Assets Ready
On this step, you will convert your previously uploaded asset into a brand new NFT. Ensure your wallet has one Catalyst for each number of NFTs you wish to mint.
Assets now mint on the Polygon network (L2). The new ERC-1155 Catalysts are required.
1. Log In and Open Workspaces
Log in to your account at The Sandbox website and open Workspaces to browse your uploaded assets. If the asset you're looking for isn't there, upload it from VoxEdit.
Open your Workspaces
2. Find Assets to Mint
Use the ... button in the bottom right of an asset's card to open the edit asset page.
2. Check Asset Details
Review all asset details carefully and make any needed changes, including the Catalyst to use. If the asset is not marked as Ready, press the ... button under the image to change its status.
After an asset is minted, you won’t be able to change any of its information.
An asset in Draft status cannot be minted. Update the status to mint.
Mint One Asset or Bulk Mint
You can mint copies of one asset or mint copies of multiple assets in one transaction.
After an asset is minted, you won’t be able to change any of its information.
You will need one Catalyst per NFT you wish to mint to set the rarity. Gems are not needed.
Minting Assets
Shown below is an example of minting one asset, but you can also bulk mint multiple assets using the instructions in this section.
Select asset(s) to mint, make changes in the minting panel, and complete the transaction

1. Log in and Open Workspaces
Log into your account on The Sandbox website and navigate to your Workspace.
It is recommended to do a final review before minting. See Get Assets Ready above.
Final Checks:
Assets you wish to mint must have the correct Catalyst selected
Assets you wish to mint must have the status set to "Ready"
You must have one Catalyst per NFT you wish to mint in the correct rarity to match the asset's saved details.
Example:
To mint 3 Legendary NFT copies of an asset, the Legendary Catalyst must be shown on the asset's edit page and you must have 3 Legendary Catalysts available to mint the copies.
