# DEEP 42 NFT

**Overview**

Non-fungible tokens (NFTs) are distinct digital assets that reside on a blockchain, each possessing a unique tokenID and contract address. This makes it possible to differentiate one NFT from another and attach metadata, such as images or video files, to create a one-of-a-kind digital asset. The primary use case for NFTs at present is digital art, allowing artists to mint tokens representing their creations and collectors to purchase these tokens as proof of ownership. It is worth noting that while adding metadata to an NFT is optional, it serves to enhance the asset's value and significance.

**Static NFT vs. Dynamic NFT**

Static NFTs, which are predominantly used by NFT art and "play to earn" game projects as digital collectibles, currently dominate the market. However, the static nature of these NFTs limits their potential, as their metadata remains fixed once minted on a blockchain. Dynamic NFTs (dNFTs) address this limitation by allowing updates to certain aspects of their metadata while retaining their unique identifiers. This makes them ideal for applications such as progression-based video games, blockchain-based fantasy sports leagues, and tokenizing real-world assets.

Dynamic NFTs are essentially NFTs that can adapt based on external conditions. These changes typically involve alterations to the NFT's metadata, triggered by a smart contract. By embedding automatic modifications within the NFT's smart contract, the asset receives instructions on when and how its metadata should change, providing greater flexibility and utility.

**DEEP 42 NFTs**

DEEP 42's NFTs are encoded with smart contracts that dictate when and how their metadata should change, allowing the characters to evolve based on user interactions within the games provided on the platform. As a result, the characters' attributes and evolution statuses can change over time, reflecting the level of care and attention players invest in their NFTs.

To engage in any of the games developed by DEEP, users must possess one of these evolving NFT characters, minted on the Ethereum blockchain network. Once minted, these NFTs can be gifted, sold, auctioned, or rented to other members across the blockchain network.

DEEP 42's system architecture and comprehensive platform enable the use of NFTs across multiple games created by DEEP 42. Utilizing an advanced approach, DEEP 42 extracts metadata from the NFTs from the blockchain and integrates it into the Unity engine, allowing for seamless gameplay across different gaming experiences.

The standard employed for DEEP 42's NFTs is ERC-721, which facilitates the tokenization of data ownership and the assignment of unique identifiers. With these unique IDs, ERC-721 tokens can represent collectible, non-fungible items, which owners can trade and transfer on various third-party marketplaces such as OpenSea, Blur, and others.
