# Customizing Avatar
JEFFWorld avatars are customizable Avatar NFTs that can be personalized according to the user's preferences. Users can swap out each part of the avatar and freely dress and undress fashion items. The updated avatar information is reflected in the holder's NFT metadata, creating an NFT that fully represents the user's identity.
### Parts NFT
Parts NFTs are issued in the form of NFTs for all traits of the avatar. When users access JEFFWorld, they can view all the Parts NFTs equipped by their avatar in their wallet and JEFFWorld inventory. Since each part is an NFT itself, they have unique designs and rarities, holding corresponding value, and can be freely traded among users.
### Minting & Marketplace
Various Parts NFTs that can embody users' preferences will be continuously minted. Look forward to Parts NFTs minted and collaborated with brands, artists, and released seasonally.
* **Genesis Parts NFT:** Parts NFTs integrated into Genesis avatar traits are limited-edition parts with high rarity. There will be no additional issuance, and they possess a high level of rarity.
* **Parts NFT Minting:** Users can mint/purchase new Parts NFTs in the workshop.
* Parts NFTs can be freely traded on the JEFF’s NFT Marketplace.
* In the future, users will be able to create and sell Parts NFTs to generate income. (TO BE ANNOUNCED!)
### Parts Spot
The avatar parts consist of a total of six spots, and users can customize their avatars by swapping parts 1:1 within the same spot (simple detachment is not possible). Among the six spots, the \[Bag] spot is reserved for occupation-specific Soul Parts, which can only be equipped by avatars with that job.

### Freeze / Unfreeze
If you want to reflect the modified parts information of your avatar in the Avatar NFT and trade it on the marketplace, you need to “freeze” your avatar. Avatars in the "Freeze" state cannot use JEFFWorld contents, and if you want to use the content in JEFFWorld again, you can proceed with "Unfreeze."
* **Freeze**: The metadata of the Avatar NFT is updated to a state that can be sold on the marketplace and stored in the user's inventory. The parts NFTs that were equipped on the avatar will be bound to the traits of the Avatar NFT and disappear.
* **Unfreeze**: The state required to use the avatar (play in JEFFWorld). Selling the Avatar NFT or modifying its metadata does not occur. The traits of the Avatar NFT are transferred to the user's wallet in the form of parts NFTs.
