The landscape of NFTs (Non-Fungible Tokens) on Ethereum is evolving rapidly. The current standard, ERC-721, has served well in enabling unique digital assets but falls short when it comes to representing complex ownership structures. Enter ERC-998 – an extension of the ERC-721 standard that introduces composable NFTs. This new standard is set to transform the way digital assets are managed and utilized on blockchain technology.
Decentralized autonomous organizations (DAOs) are also composable elements in blockchain technology, enabling developers to reuse code and create new dApps without starting from scratch.
Blockchain protocols play a crucial role in enabling composable NFTs by allowing different smart contracts and decentralized applications to interconnect and create new, innovative systems.
Understanding ERC-998 and Smart Contracts
ERC-998 is a standardized contract interface that extends the functionality of ERC-721 tokens. It introduces a groundbreaking feature called “composability,” which enables an NFT to own other NFTs (ERC-721) or fungible tokens (ERC-20). Composability refers to the ability to combine existing blockchain components in multiple ways to create something new, whether in software development, DeFi protocols, or by connecting different DeFi applications and protocols seamlessly at a code or interface level. This concept is closely related to DeFi composability, which emphasizes the potential to use codes, smart contracts, APIs, and SDKs of existing decentralized applications in endless combinations to create new applications or build new services. This means that NFTs can now be composed of multiple components, creating a hierarchy or relationship between them.
In simpler terms, ERC-998 allows for the creation of complex digital assets by combining smaller, simpler NFTs and/or ERC-20 tokens. This enhanced functionality opens up a myriad of possibilities for how digital assets are structured, managed, and utilized on the blockchain.
Types of ERC-998 Tokens
There are two types of composability when it comes to ERC-998 tokens: top-down and bottom-up. Atomic composability in this context allows combining multiple actions into a single transaction, ensuring that all parts succeed, which promotes code reusability and modularity within the blockchain community. Syntactic composability refers to the ability of different components, protocols, or smart contracts to seamlessly integrate and work together without conflicts, achieved through the standardization of interfaces and communication methods.
Top-Down Composability
Top-down composable tokens own and manage a collection of child tokens, which can be either NFTs or fungible tokens. A good example of this is an in-game character owning various items like weapons and armor as individual NFTs or ERC-20 tokens. This hierarchical approach allows for complex assets to be managed under a single parent token, facilitating easier transactions and ownership management.
Bottom-Up Composability
On the other hand, bottom-up composable tokens can be attached or linked to a parent NFT. These tokens are often non-transferable and serve as badges of achievement or certifications linked to an NFT representing a profile. This approach allows for the addition of supplementary information or attributes to an existing NFT, enhancing its value and utility.
Key Features and Capabilities of ERC-998
One of the significant advantages of ERC-998 is its hierarchical ownership feature. This allows for the creation of complex ownership trees or nested structures of NFTs, providing a more comprehensive representation of digital assets.
Hierarchical Ownership
ERC-998 enables the establishment of a parent-child relationship between tokens, allowing a single token to own multiple child tokens. This hierarchical structure is particularly useful in scenarios where a main asset consists of several sub-assets, such as a virtual character owning various items or a digital portfolio containing multiple artworks. This feature is critical for maintaining the coherence and integrity of composite assets during transactions.
Ease of Transferability
Another key feature is the ease of transferability for composite tokens. With ERC-998, an entire asset composed of multiple NFTs and ERC-20 tokens can be transferred in a single transaction, simplifying ownership and potential marketplaces. Syntactic blockchain composability plays a crucial role here, ensuring seamless interaction and integration of different components within the blockchain ecosystem. This streamlined process enhances the user experience and operational efficiency in managing digital assets.
Atomic Transactions
The atomic transaction feature ensures the integrity and consistency of composite token transfers. This means that either all child tokens will be transferred together with the parent token or none at all, avoiding any discrepancies or issues. This feature is crucial for maintaining the consistency and reliability of composite assets, ensuring that all components of an asset are transferred simultaneously and intact.

ERC-998 tokens have the potential to transform real-world asset representation on the blockchain. Different protocols play a crucial role in enabling seamless integrations and security considerations when representing real-world assets on the blockchain. For example, real estate ownership could potentially be fractionalized and represented by ERC-998 tokens, allowing for easier ownership transfers and investment opportunities. This application could revolutionize how real estate and other tangible assets are managed, traded, and utilized in the digital economy.
Identity & Credentials
Badges, certifications, and other non-transferable achievements can be linked to an identity NFT using bottom-up composable tokens. Morphological composability allows these basic elements or functionalities to combine and create more complex systems, enhancing the overall structure. This provides a secure and verifiable way to showcase one’s achievements or credentials. This application is particularly relevant in educational and professional contexts, where verifying and managing credentials and achievements are essential.
Detailed Examination of ERC-998’s Capabilities
Hierarchical Ownership: A Game-Changer for Complex Digital Assets
The hierarchical ownership feature of ERC-998 enables the creation of intricate asset structures. This is especially valuable in scenarios requiring detailed representation of ownership. For instance, in a gaming context, a character (parent NFT) might own various items such as weapons, armor, and potions (child NFTs). Each of these items can further possess attributes like durability, enchantments, or modifications, all of which can be represented as additional NFTs or ERC-20 tokens.
This hierarchical model provides a comprehensive framework for representing complex digital assets, enhancing both the flexibility and depth of asset management. It also facilitates easier transfer and sale of entire asset bundles, as opposed to dealing with numerous individual transactions.
Transferability and Atomic Transactions: Simplifying Asset Management
ERC-998 significantly simplifies the transfer of composite assets. Traditional ERC-721 tokens require multiple transactions to transfer a collection of assets. With ERC-998, a single transaction can transfer the entire composite asset, including all its constituent NFTs and ERC-20 tokens. This efficiency is achieved through atomic transactions, which ensure that all parts of the composite asset are transferred simultaneously or not at all. This all-or-nothing approach guarantees the integrity of the transfer process, preventing partial transfers that could lead to discrepancies or loss of asset components.
Enhancing Digital Collectibles: From Simplicity to Complexity
Digital collectibles benefit immensely from the composability features of ERC-998. Collectors can bundle multiple related NFTs into a single composite NFT. For example, an art collector could create a composite NFT that includes multiple artworks from the same series, along with associated certificates of authenticity and provenance records.
This bundled approach not only simplifies ownership and transfer processes but also enhances the overall value and appeal of the collectibles. Collectors and investors can manage and trade composite assets more effectively, leveraging the combined value of the entire bundle.
Real-World Asset Representation: A New Frontier
The potential of ERC-998 to represent real-world assets on the blockchain is transformative. Real estate is a prime example where this standard can bring significant innovation.
