This protocol is also known as ERC721X, which extends the ERC721 standard to allow users to remix multiple existing NFTs and create a new NFT derivative work, while their relationships can be traced on the blockchain. It contains three core modules, remix module, network module, and license module.

Remix Module

This module extends ERC-721 standard and enables users to create a new NFT by remixing multiple existing NFTs, whether they’re ERC-721 or ERC-1155.

// SPDX-License-Identifier: CC0-1.0
pragma solidity ^0.8.10;

    // Events

    /// @dev Emits when a combo is minted.
    /// @param owner The owner address of the newly minted combo
    /// @param comboId The newly minted combo identifier
    event ComboMinted(address indexed owner, uint256 indexed comboId);

    // Structs

    /// @param tokenAddress The NFT's collection address
    /// @param tokenId The NFT identifier
    struct Token {
        address tokenAddress;
        uint256 tokenId;
    }

    struct Component {
        Token token;
        uint256 amount;
        uint256 licenseId;
    }

    // Functions

    /// @dev Mints a NFT by remixing multiple existing NFTs.
    /// @param components The NFTs remixed to mint a combo
    /// @param hash The hash representing the algorithm about how to generate the combo's metadata when remixing multiple existing NFTs.
    function mint(
        Component[] calldata components,
        string calldata hash
    ) external;

    /// @dev Retrieve a combo's components.
    function getComponents(
        uint256 comboId
    ) external view returns (Component[] memory);
}

Depending on the different NFT derivative works, the parameters required in the mint function of the respective remix module vary.

In the NFT Derivatives section, we will provide examples of how to create NFT derivative works through 1Combo.

Network Module

This module follows the singleton pattern and is used to track all relationships between the original NFTs and their NFT derivative works.

// SPDX-License-Identifier: CC0-1.0
pragma solidity ^0.8.10;

import "./IERC721X.sol";

interface INFTNetIndexer {
    /// @dev Verify if the `child` was created by remixing the `parent` with other NFTs.
    /// @param parent Any NFT
    /// @param child Any NFT
    function isParent(
        IERC721X.Token calldata parent,
        IERC721X.Token calldata child
    ) external view returns (bool);

    /// @dev Verify if `a` and `b` have common `parent`s
    /// @param a Any NFT
    /// @param b Any NFT
    function isSibling(
        IERC721X.Token calldata a,
        IERC721X.Token calldata b
    ) external view returns (bool, IERC721X.Token[] memory commonParents);

    /// @dev Return all parents of a `token`
    /// @param token Any NFT
    /// @return parents All NFTs used to mint the `token`
    function getParents(
        IERC721X.Token calldata token
    ) external view returns (IERC721X.Token[] memory parents);
}

Whenever a Combo is created, the network module will be notified to record the newly generated network relationship, making it public and immutable for other applications.

In the NFT Network section, we will explain the different types of network relationships.

License Module

By default, users can only remix multiple NFTs they own to create new NFT derivative works. This module enables NFT holders to grant others permission to use their NFTs in the remixing process.

// SPDX-License-Identifier: CC0-1.0
pragma solidity ^0.8.10;

import "./IERC721X.sol";

interface ILicense {
    /// @dev Verify the permission when minting a combo
    /// @param user The minter
    /// @param combo The new NFT to be minted by remixing multiple existing NFTs
    /// @return components The multiple existing NFTs used to mint the new combo
    function verify(
        address user,
        IERC721X.Token calldata combo,
        IERC721X.Component[] calldata components
    ) external returns (bool);
}

Depending on the specific NFT licensing method, the verify function of the respective license module is triggered to ensure the minter owns the necessary permissions to create the new NFT derivative work.

In the NFT License section, we will introduce several common licensing methods.

Combo

A Combo refers to a unique, newly minted NFT derivative work that is created by remixing multiple existing NFTs. In 1Combo, selecting the Combo button will lead you to create a new NFT derivative work.

Combo Magic & Combo Collection

Combo Magic, also called 'Magic', is a template for creating NFT derivative works. "Magic" contains one or more Stickers or Potions. When 'Magic' is applied to a target NFT collection, it generates a new NFT derivative collection known as 'Combo Collection'.

Sticker & Potion

In 1Combo, text, images, audio, videos, and even Mid-Journey's prompt can be remixed with the original NFT to generate NFT derivative works. These text, images, audio, videos, and Mid-Journey's prompt are referred to as Sticker or Potion.

NFT Derivatives

Multiple existing NFTs can be remixed to create a new NFT derivative work, also known as NFT derivatives or "Combo". All NFTs in a Combo Collection are NFT derivatives.

NFT Network

Using the NFT network, the relationship between the original NFT and its derivative works can be identified and tracked on the blockchain.

NFT License

In 1Combo, individuals can not only remix multiple NFTs they own to create derivative works, but also have the ability to license NFTs in diverse ways. NFT holders are encouraged to grant others permission to use their NFTs in the remixing of NFTs.

Share to Earn

"Share to Earn" is one type of NFT license that allows other users to trade shares of your NFT license and enables you to profit from it. These traded shares can be used as the original NFT to be remixed with other NFTs and create new NFT derivative works.

In 1Combo, elements like text, image, audio, video, and even Mid-Journey's Prompt can be remixed with the original NFT to generate unique NFT derivative works. These elements are termed as Sticker or Potion.

The difference between Sticker and Potion lies in the visual appearance of the NFT derivative work generated after remixing with the original NFT. With a Sticker, the visual appearance of the original NFT remains unchanged, while with a Potion, it changes. For instance, adding decorations to your PFP-type NFT uses a Sticker. However, transforming your PFP NFT from an adult appearance to that of a child requires a Potion.

Here are two examples：

Example 1 - Sticker

Cosplay Ape is a derivative NFT collection of BAYC, also known as a Combo Collection. Every BAYC can be dressed up in this series.

Users can choose one Sticker-type NFT each from the Hat, Earring, and Clothing collections, and then remix them with their own BAYC NFT to create a new NFT derivative work in the Cosplay Ape collection. During the remixing process, users can adjust the size, position, and angle of these four NFTs, but the visual appearance remains unchanged. Once remixed, the Sticker-type NFTs are consumed.

Example 2 - Potion

Mutant House is a derivative NFT collection of MAYC, where any MAYC can transformed into a unique house.

Users can remix their own MAYC NFT with a Potion-type NFT named House Potion to create a new NFT derivative work in the Mutant House collection. During the remixing process, the Mid-journey's prompt recorded in the House Potion will be utilized by AI to create a House based on the original MAYC image, retaining the original MAYC's traits but with a dramatically altered visual appearance. Once remixed, the Potion-type NFTs are consumed.

Conclusion

Regardless of whether the appearance of the original NFT changes during the remixing process, the relationships between the original NFT and all its NFT derivative works are traceable on the blockchain. This introduces a new narrative within the NFT ecosystem: NFT Network.

IP & Open IP

The internet is flooded with fresh content every day. But with the traditional IP infrastructure, IP registration and licensing is challenging for digital creators. The rapid creation of digital content has eclipsed the slower pace of IP registration, leaving much of this content unprotected. This means digital creators can't fairly earn from their work's spread.

With this backdrop, we're passionate about building an Open IP ecosystem tailored for today's digital creators. Here, with just a few clicks, creators can register, license, and monetize their content globally, without geographical or linguistic barriers.

Our Solution - 1Combo

1Combo is an open IP protocol that enables decentralized AI-powered IP remixing, peer-to-pool IP trading, and on-chain IP tracking.

IP Remixing - NFT Derivatives

With 1Combo's creative tools, text, images, audio, video, and even Mid-Journey's Prompt can be remixed with the original NFT to generate unique NFT derivative works.

IP Trading - NFT License

With 1Combo's innovative IP market, NFT holders can use a special math trick (called the bonding curve algorithm) to sell their NFT licenses in shares. People can trade these shares or use them to make new NFT derivative works.

IP Tracking - NFT Network

With 1Combo's remixing magic, original NFTs and their NFT derivative works are automatically linked within the on-chain NFT network.

Absolutely, users can remix their own NFTs to create new NFT derivative works. Also, with the Delegate protocol, users can grant a "hot wallet" to access an NFT from their secure "cold wallet". Then, this "hot wallet" can remix the NFT with others to create new NFT derivative works.

About Us

1Combo started with a group of passionate BAYC fans. A big shoutout to Yuga Labs - their decision to open BAYC's IP led to its impressive growth, which inspired us. Over the past year, more and more NFT OGs have joined us in building an open IP ecosystem for the global youth. Thanks for the support, and we're pushing forward with determination!

By default, users are typically limited to remixing NFTs they own to create new NFT derivative works. However, to enhance IP liquidity, 1Combo offers diverse NFT licensing methods enabling NFT holders to grant others permission to use their NFTs and create new NFT derivative works. Here, we highlight two such methods.

NFT Share

The optimal solution for maximizing IP liquidity is to tokenize NFT license and then build a decentralized NFT license liquidity market. Among various tokenization methods, 1Combo prioritizes the one based on the Bonding Curve to issue shares of NFT license.

In this approach, the holder or a delegated individual of a specific NFT can activate its NFT Share, allowing anyone to buy and sell shares of the NFT license. If a user purchases a share of a specific NFT, even if they don't own that NFT, they can use up one share to obtain permission to remix that NFT with others to create a new derivative work.

As mentioned above, the sold shares of an NFT can be in two states: unused and used. If we denote the unused sold shares of an NFT as S and the used ones as D, then the price for the next NFT share adheres to the following Bonding Curve formula. Users can freely buy or sell unused shares at the price calculated by this formula.

The first share of each NFT is free and gifted to the NFT holder when its NFT Share is activated. Additionally, each share trade has a 10% tax, of which:

• 5% can be withdrawn by the current NFT holder. If the NFT holder does not claim the earnings before transferring the NFT, then the new NFT holder can withdraw all accumulated earnings.

• 2.5% is equally distributed to the current holders of all NFT derivative works created using the share. These earnings also need to be claimed by the holders of the NFT derivative works. If the ownership of the derivative NFT is transferred before the claim, then the new derivative NFT holder can withdraw all accumulated earnings.

• 2.5% goes to 1Combo as protocol revenue.

NFT Delegation

Without transferring the NFT, any NFT can be delegated to another wallet by its holder using the Delegate protocol for verification in token-gated applications, such as Token Proof and Collab.Land.

Similarly, 1Combo also supports the Delegate protocol when verifying whether a user owns a specific NFT. This means users can remix NFTs delegated to them to generate new NFT derivative works.

In 1Combo, the relationships between the original NFT and all its NFT derivative works are traceable on the blockchain. Here, we categorize these relationship as:

• Parent Relationship: Connects the original NFTs to their derivatives.

• Sibling Relationship: Binds NFT derivatives that have a common original NFT.

• Partner Relationship: Ties together the original NFTs that were remixed to create a new one.

Using the "On-chain Map" feature in 1Combo, users can view the parent and all the children of any NFT within the NFT Network.

The NFT network woven from these relationships will become the new NFT infrastructure, bringing new possibilities for NFT applications.

A new era of NFT

1Combo is creating a fully open and decentralized network for NFTs. Accessing these relationships doesn't require permission from any third party. Any contract can access these relationships, paving the way for designing more open, engaging, and innovative NFT applications.

1Combo aims at an open IP ecosystem. Within the 1Combo ecosystem, there are 5 types of participants: NFT holders, NFT Share traders, NFT derivative works investors, Combo Magic creators and Combo Collection creators. Every participant can benefit fairly from the growth of IP.

Next, we will introduce the economic models of these participants.

NFT Holders

NFT holders possess both IP ownership and IP license rights. With these rights, they can create and trade derivative works. Additionally, they can activate the "NFT Share" features for their NFTs, allowing others to trade shares of the NFT's License. Once activated, NFT holders can obtain one free share and also benefit from 5% tax on each share trade.

NFT Share Traders

According to the Bonding Curve of , the more shares sold, the higher the price of each share. NFT Share traders profit by buying shares of a particular NFT and selling them when the share price rises, with a tax rate of 10%.

NFT Derivative Works Investors

Investors in NFT derivative works profit by purchasing shares of a specific NFT and using that share to create licensed NFT derivative works. All derivative works licensed by a particular NFT can equally divide the 2.5% tax from each of its share trade. The remaining 2.5% tax from each NFT Share trade goes to 1Combo as protocol revenue.

Combo Magic Creators

Combo Magic creators are whitelisted derivative artists. When these artists reimagine a particular IP, they might need additional IPs like fonts, images, videos, audios, or even Mid-journey Prompts. These additional IPs can be converted into NFTs for rights registration and pricing, and then be bundled into a Combo Magic. When other users utilize this Combo Magic to generate derivative works, the creators of these additional IPs can earn profits.

Combo Collection Creators

The core tasks of Combo Collection creators include idea discovery and community operations. They have a keen sense of active market participants. Additionally, they understand which target Collection should receive a specific Combo Magic to boost the sales of derivative works. They can set a mint fee for each derivative works to earn profits. 1Combo takes an additional one dollar from each mint as protocol revenue.

A peer-to-pool market for trading NFT Shares with prices determined by a bonding curve. Each trade incurs a 10% tax fee:

• 5% goes to NFT holders,

• 2.5% to Combo NFT holders,

• 2.5% to the platform.
