A dynamic NFT (dNFT) is an advanced form of a non-fungible token (NFT) that incorporates smart contract logic, allowing it to autonomously update its metadata in response to external factors. 

NFTs have gained significant traction in the Web3 community and beyond, positioning NFTs as a critical blockchain application in the public eye. The evolution of NFTs is entering a new phase with the introduction of dynamic NFTs (dNFTs). These dNFTs enhance the capabilities of traditional NFTs by dynamically adapting to external inputs and data. 

What Is An NFT?

NFTs are unique digital assets on a blockchain, each identified by a token ID and contact address. They can carry various forms of metadata, like images or videos, allowing for the ownership of unique digital objects. 

Mainly used in digital art, NFTs enable artists to mint tokens representing the artist’s artwork, which collectors can purchase to establish ownership. This model has revolutionized the digital art world by providing a way to authenticate and own original digital painting, addressing the long-standing unauthorized distribution and replication issue. 

In essence, NFTs represent a significant shift in digital ownership, offering verifiable authenticity and ownership of digital creations.

Most Expensive NFT Sold To Date

One notable example of an NFT selling for a significant amount is the artwork “Everydays: The First 5000 Days ” by the digital artist Beeple (Mike Winkelmann). This NFT sold for $69.3 million at a Christie’s auction in March 2021. The artwork is a collage of 5,000 individual images, which Beeple created one per day over 13 years. 

The NFT sale marked one of the highest prices ever paid for digital artwork and significantly elevated the profile of NFTs in the art world and beyond.

Static Vs. Dynamic NFTs (dNFTs)

Static NFTs, prevalent in digital art, play-to-earn games, and collectibles, can digitize unique real-world items like property deeds or patents. 

Static NFTs hold limitations, mainly in the unchangeable nature of their metadata once minted on the blockchain. This static feature restricts NFT use in dynamic scenarios like real-world asset tokenization or evolving gaming experiences.

Dynamic NFTs, on the other hand, are designed to adapt and change. Where dynamic NFTs’ metadata is governed by smart contract logic, the dNFT can automatically update in response to external factors. 

This adaptability extends beyond metadata, allowing for innovative uses like minting NFTs under specific conditions in augmented reality apps or revealing hidden features through user interaction. 

While dynamic NFTs can be programmed in numerous ways, visible metadata changes are often essential for making these adaptations perceptible to users.

How Does A Dynamic NFT Work?

To create a dynamic NFT, three key components are necessary:

Smart Contract Foundation For NFTs

The first step involves creating a robust NFT smart contract, typically based on established standards such as ERC-721 or ERC-1155, or using similar standards from other blockchains to ensure compatibility and functionality within a blockchain ecosystem.

External Data Integration

Essential for dynamic NFTs, this next step involves connecting the dNFT to external data sources to bring real-world information into the blockchain. This is usually achieved through blockchain oracle services, with Chainlink being a prominent example to bridge the gap between off-chain data and on-chain NFTs.

Automated Metadata Updates

Finally, to make NFTs dynamic, there’s a need for a mechanism that triggers automatic updates in the NFT’s metadata based on specific conditions. 

This is often accomplished using automation services like Chainlink Automation, which enable NFTs to change and evolve in response to external events or data.

Integrating these three essential elements above will allow developers to craft dynamic NFTs that can autonomously update based on specific data parameters. This integration brings a new dimension of interactivity and functionality to NFTs that were once static.

Applications Of Dynamic NFTs

Dynamic NFTs bring versatility to the traditional NFT format, where metadata is crucial in defining the token’s characteristics, such as its name, attributes, and linked digital files. Here are some critical applications of dNFTs:

Evolving Art And Gaming NFTs

When integrating art and collectibles with NFTs, various unique traits, including some of a rare nature, are encoded in the metadata, accompanied by links to related images or videos. Dynamic NFTs take this further by enabling the mentioned traits to evolve in response to external influences.

This adaptability is particularly impactful in blockchain gaming, where character development is fundamental. For instance, a blockchain game character, initially with essential attributes in its metadata, can evolve as the player progresses, with the dNFT metadata updating to reflect this growth.

Tokenization Of Physical Assets

Dynamic NFTs are also pivotal in tokenizing real-world assets that require dynamic metadata. Take, for example, a property NFT, which could update its metadata to include maintenance records, age, or fluctuating market values. 

This dynamic nature is essential for accurately representing assets whose characteristics change over time.

The Expansive Potential of dNFTs

The possibilities for dNFTs are vast; with metadata incorporated within an NFT, it may trigger various on-chain or off-chain events. 

Metadata changes may offer flexibility within the dNFT, opening up many applications beyond the current scope of static NFTs.

While the Web3 space is still predominantly occupied by static NFTs, some pioneering projects are already exploring the innovative frontiers of dNFT technology.

Some projects include exploring the creative possibilities of dynamic NFTs in the Web3 space. Some notable examples include:

Async Art

A platform where artists can create, sell, and collect programmable art. With dNFTs, that can change appearance based on external inputs or decisions made by the token holders.
