Our latest breakthrough in the domain of dynamic smart contracts - is the ERC-7160. Building on the foundation laid by its predecessor, Doppelgänger, ERC-7160 redefines the NFT experience by introducing multi-metadata functionality at the token level. Authored by 0xG and Marco Peyfuss, co-founder of Transient Labs, the ERC-7160 standard is detailed in the Ethereum Improvement Proposal, which can be found here. This development marks a significant leap forward, offering unparalleled flexibility and interaction for creators and collectors.


What Sets ERC-7160 Apart

Central to ERC-7160 is a groundbreaking feature that fundamentally changes how NFTs operate. Imagine each token within an ERC-7160 contract as a unique digital gallery, where instead of just one piece of artwork, it can showcase a whole collection of different artworks or digital files. This is what ERC-7160 achieves - it allows each token to connect to multiple pieces of digital content or metadata.

In contrast to the Doppelganger standard, where all tokens under a single contract point to a common set of artworks or files, ERC-7160 empowers each token with its unique set of connections. Think of it as having a collection of personalized digital art exhibits, where each token is a distinct exhibit with an array of artworks. This means that every token can tell its own story, display a series of artworks, or even evolve over time with new additions, offering a richer and more personalized experience for the collector.

This unique capability of ERC-7160 not only diversifies what digital artwork can represent but also deepens the connection between digital collectors and the art they own, making each token a dynamic and evolving piece of digital property.

Innovative Use Cases and Future Prospects of ERC-7160

  1. Dynamic Metadata Revision History: One of the most revolutionary aspects of ERC-7160 is how it transforms the process of metadata updates in NFTs. When an artwork associated with an NFT needs to be updated, the original metadata is permanently replaced. However, ERC-7160 introduces a more dynamic approach. With this standard, creators can append new versions of the artwork to the token's metadata array, creating a 'revision history'. This means that the original metadata is preserved within the array. Collectors can then navigate through and display any version of the artwork from this history, allowing them to experience and maintain the full evolution of the piece over time.

  2. Enhanced Collector Rewards: ERC-7160 also opens up innovative avenues for rewarding collectors. Instead of the traditional method of airdropping new tokens, creators can add new metadata to existing collector's tokens. This provides collectors with fresh content and maintains the original NFT's exclusivity and value. It's a more integrated and sustainable way of enriching a collector's digital portfolio without inflating the artist's overall supply of minted tokens.

  3. Building Long-Term Collector Relationships: By adding new metadata to existing tokens, ERC-7160 fosters a long-term relationship between artists and collectors. This ongoing engagement keeps collectors invested in the artist's evolving narrative and portfolio, creating a deeper and more meaningful connection.

  4. Versatile Applications for Creators: This feature is particularly beneficial for creators who work in mediums that evolve over time, such as digital artists, musicians, and writers. For instance, a writer can release chapters of a story over time, or a musician can update a song with new versions or remixes, all under the same token.

  5. New Use Cases Yet to be Discovered: The introduction of ERC-7160 paves the way for innovations yet to be imagined in digital art. Its flexible and dynamic nature invites creators, developers, and collectors to explore new possibilities and applications. Some potential future use cases could include:

    • Interactive Storytelling: Writers and artists could collaborate to create tokens that evolve with the audience's input, leading to interactive and branching narratives.

    • Dynamic Gaming Assets: In the gaming world, ERC-7160 could allow for in-game assets that evolve based on player achievements or changes within the game universe.

    • Educational and Instructional Content: ERC-7160 tokens could be used for educational purposes, where the content evolves or expands over time, providing updated or additional learning materials.

    • Layered Artistic Experiences: Artists could create multi-layered artworks where each layer is revealed over time or under specific conditions, offering a unique unfolding experience to the collector.

    • Cultural and Historical Documentation: ERC-7160 tokens could serve as living documents that record cultural or historical events, adding new information and perspectives over time.

    • Personalized and Evolving Merchandise: Brands could use ERC-7160 to offer merchandise that evolves with the owner, such as digital apparel that changes style or color based on trends or seasons.



For creators, it's a canvas of endless possibilities. It enables the evolution of artwork over time and fosters a deeper connection with collectors. Its ability to accommodate collaborative artwork allows for diverse artistic expressions within a single token. As we enable ERC-7160, we anticipate its impact in shaping the NFT ecosystem, transforming digital ownership into a living, evolving journey.
