RMRK is an advanced NFT protocol enabling dynamic, multi-functional, and interoperable digital assets across multiple blockchain platforms.

What is the RMRK NFT standard?

RMRK is a cutting-edge NFT protocol designed to operate across multiple blockchain platforms. Unlike traditional NFTs, which are often static and limited in capabilities, RMRK provides a robust framework for creating dynamic and interactive digital assets. This protocol supports the creation of complex, multi-functional NFTs that can evolve and interact with their environment.

As the NFT ecosystem evolves, RMRK distinguishes itself with groundbreaking features that offer unprecedented functionality and flexibility.

This article explores RMRK, its unique features—such as nested NFTs, conditional rendering, multi-asset NFTs, composable and equippable NFTs, Soulbound 2.0, Emotable NFTs, ERC-20 Token Holder, and on-chain attributes—and how it differentiates itself from other NFT protocols.

Unique Features of RMRK

Nested NFTs

Definition: Nested NFTs allow one NFT to own other NFTs. This hierarchical structure enables the creation of complex assets where a parent NFT can hold multiple child NFTs. Example: In a game, a character (parent NFT) can own various items like weapons, armor, and pets (child NFTs). Each item can be traded or upgraded independently.

Multi-Asset NFTs

Definition: Multi-asset NFTs can include multiple types of media or data assets within a single NFT. This allows an NFT to be represented in various formats and contexts. Example: A single NFT that can display a 2D image, a 3D model, an audio track, and a text description. Depending on the platform or application, different assets can be accessed and utilized.

Composable and Equippable NFTs

Definition: Composable NFTs can be equipped with other NFTs, enhancing their functionality or appearance. Equippable NFTs allow specific parts of an NFT to be replaced or upgraded. Example: In a game, a character NFT can equip various items like swords, shields, and armor. These items can be swapped out or upgraded as the player progresses.

Soulbound 2.0

Definition: Soulbound NFTs are non-transferable and are permanently bound to a specific wallet or NFT. Soulbound 2.0 introduces enhanced functionalities and conditions for these NFTs. Example: Achievements or certifications that are permanently associated with a user’s profile and cannot be transferred or sold.

Emotable NFTs

Definition: Emotable NFTs allow users to attach reactions or emotions to NFTs, creating a more interactive and social experience. Example: Users can react to a digital artwork with emojis or comments, enhancing community engagement around the NFT.

On-Chain Attributes

Definition: On-chain attributes allow dynamic data and properties of NFTs to be stored directly on the blockchain, ensuring immutability and transparency. Example: A game character’s attributes such as strength, agility, and intelligence are stored on-chain and can be updated based on the character’s progress.

ERC-20 Token Holder

Definition: This feature extends NFTs to hold ERC-20 tokens, integrating fungible tokens within non-fungible tokens. Example: An NFT representing a virtual real estate property that also holds a certain amount of in-game currency (ERC-20 tokens).

How RMRK Stands Out

Interoperability: RMRK is designed to work seamlessly across different blockchain platforms, ensuring broad compatibility and reach. This cross-chain functionality makes RMRK a versatile choice for developers and creators looking to expand their audience and market.

Flexibility and Customization: The advanced features of RMRK, such as nested NFTs, multi-asset capabilities, and more, offer creators unparalleled flexibility. Artists, developers, and collectors can customize and interact with their NFTs in ways that were previously impossible.

User Experience: RMRK focuses on enhancing the user experience by providing tools and functionalities that make NFTs more engaging and interactive. Whether through dynamic art pieces or complex in-game assets, RMRK aims to push the boundaries of what NFTs can offer.

RMRK has developed dApps for an enhanced user experience:

  • NFT marketplace
  • Supercharge ERC721 NFTs into Modular NFTs
  • Create NFTs without upfront costs
  • React with on-chain emotes in any NFT
  • Metaverse gaming to showcase everything RMRK tech can do
