# NFTs

AL Parts (loot-style NFTs for monster assembling) support user-generated NFT operations.

AL Parts in the ArchLoot game are generic units for monster assembling. They come in 5 types, head, torso, upper limb, lower limb, and accessory, to enable lego-like composable gameplay.

AL Parts, by its technical nature, are loot-style NFTs that support can support user-generated NFT operations. Powered by self-developed protocols [**EIP-4985**](https://github.com/ethereum/EIPs/pull/4985) and [**BEP-129**](https://github.com/Connector-Gamefi/BEPs/blob/BEP-129/BEP129.md#523-treasure-contract-implementation)**,** these NFTs align gamers' choices of creation with corresponding underlying metadata change in a trustless manner.

[**EIP-4985**](https://github.com/ethereum/EIPs/pull/4985) **and** [**BEP-129**](https://github.com/Connector-Gamefi/BEPs/blob/BEP-129/BEP129.md#523-treasure-contract-implementation) **are protocols born for GameFi:**

* The technology enhances the features of Loot.
* The technology allows the creation of any digital properties in the form of numbers, with every piece of metadata stored on the chain.
* Compared to the text form, the form of numbers significantly lowers the barrier to cross-ecosystem collaboration. NFTs are now the magical Bifrost to various games.
* The best part is that it supports real-time modifications with validation, allowing owners to modify the metadata of the NFT subject to certain rules.

**Gamers can:**

> Freely assemble and recombine avatars from a directory of NFTs
>
> Change/ upgrade/ enhance the attributes and design of NFT assets during playing
>
> Unlock unexpected performance by recombination
>
> Sell them on secondary marketplaces
>
> Safe transactions and real-time metadata protection

As a highly expansive technology derived from LOOT, it also provides a wide range of possibilities for the AL community to interact with other ecosystems.
