NFTs stormed the scene in 2020 and clinched the title of “word of the year” in 2021. But their immutable nature, which means they can’t be changed after being created, posed certain limitations. Addressing these shortcomings, Dynamic NFTs (dNFTs) are positioned as a potential solution to the constraints of traditional NFTs. In this guide, we’ll delve into this new trend and its distinguishing features.

Dynamic NFTs: The ever-evolving canvas of the digital age
NFTs, or Non-Fungible Tokens, have piqued the curiosity of many. For one not acquainted with the term, picture NFTs as distinctive digital trading cards, with each being as unique as a one-of-a-kind baseball card. Yet, as captivating as they are, traditional NFTs come with a limitation — their immutable nature means once they’re minted, they remain unchanged forever. This static characteristic can be a hindrance, especially in scenarios where the adaptability or evolution of the asset is desired.
Dynamic NFTs are a special breed of NFTs, armed with encoded smart contract logic. This allows them to tweak their metadata — the core information that defines them — based on a myriad of external conditions. What does this mean in simple terms? Imagine having an NFT that changes its appearance or features based on real-world factors, be it the weather, a sports score, or even its holder’s actions.
Examining dNFTs, these are their defining characteristics:
Evolving Metadata: Unlike traditional NFTs that are static, this class of NFTs can change and evolve. Today’s sunny weather might make your dNFT artwork sport sunglasses, and a rainy day might have it holding an umbrella.
Characteristics Alteration: The attributes of such NFTs aren’t set in stone. Their names, descriptions, and other intrinsic features can alter as conditions change.
Smart Contract Logic: At the heart of this adaptability is a digital contract system that defines how and when these changes occur.
To put it into perspective with traditional NFTs: if you wanted an NFT to “evolve”, you’d have to burn (or destroy) the original and mint (or create) a new one — a cumbersome process, especially in scenarios like video games where characters might need to evolve frequently. With dNFTs, that evolution is seamless and intrinsic.
How do dNFTs get the information to change their data?
Let’s take a moment to think about a practical example: you own a digital artwork that depicts a serene outdoor scene. Wouldn’t it be fascinating if this artwork displayed sunny weather when it’s bright outside and shifted to a rainy mood when it pours?
But how does the artwork “know” about the weather? The process needs to be automatic, seamless, and immediate. And that’s where the operational mechanics of dNFTs come into play.
Imagine the artwork as a sophisticated toy that adjusts its appearance in real-time. The smart contracts embedded within dNFTs serve as the inner workings of this toy, dictating how it should react to external conditions. However, these smart contracts can’t “peek out of the window” on their own. They need an informant—a reliable source that tells them precisely what’s happening outside.
Enter oracles. They function as the eyes and ears for the dNFT, constantly pulling in real-world data, be it weather conditions, stock market prices, or any other measurable metric. Once the oracle captures this data, the smart contract processes it and triggers the appropriate change in the dNFT, ensuring the asset remains dynamic and responsive.
In essence, dNFTs depend heavily on oracles to stay updated. Without them, the dynamic essence of these tokens would be lost, making the seamless automatic changes we admire a mere impossibility.
Adaptive applications: the expansive reach of dNFTs
Dynamic NFTs offer a breadth of applications thanks to their responsive nature, influenced by both digital and real-world events:
Gaming and the Metaverse: Within a game, dNFTs can represent items, characters, or assets that transform based on in-game events. Imagine an avatar that evolves not only from in-game actions like completing missions or leveling up but can also change based on real-world events or date/time conditions.
Digital Art: Art can be more than just static; it can be reactive. A digital piece might alter its appearance based on the number of views it gets or change hues according to real-world seasons.
Collectibles: Collectible dNFTs can be more than just static memorabilia. A sports card, for instance, could update in real-time with player stats from recent games and can also evolve based on digital interactions like trades or achievements in fantasy leagues.
Real Estate: Tokens representing real estate can automatically update to reflect current property values, renovations, or transaction histories, offering a transparent and dynamic record for all stakeholders.
Digital Identity: A person’s digital identity in dNFT form can adjust based on both on-chain events like contractual agreements or off-chain changes in personal circumstances, ensuring a relevant and up-to-date digital representation.
Sports: This field can revolutionize ticketing for events, offering unique digital experiences based on real-time game outcomes, or they could change in value based on digital predictions and betting outcomes.
Rewards and Royalties: In creative fields, dNFTs can represent a new method for distributing rewards. As sales or streams reach specific milestones, dNFTs could trigger automatic royalty payments, creating a dynamic and transparent system for artists and creators.
dNFTs’ capability to respond to a diverse array of triggers, be they in the digital domain or the tangible world, cements their position as versatile assets for numerous industries.
