Burgeoning into the digital landscape, Non-Fungible Tokens (NFTs) are writing a new narrative for the concept of value and ownership. But to fully comprehend and navigate this dynamic terrain, one needs a strong grasp of the native lingo, much like a map to guide a road trip.

Maincard, a fantasy management platform harnessing the power of blockchain technology, stands out as a beacon for newcomers and seasoned veterans alike in this exciting journey.

But to truly make the most of this or any other platform in the NFT universe, understanding the vocabulary of this innovative field is key. So, let’s embark on a linguistic voyage to decode the key terminologies you’ll encounter in the world of NFTs.


For NFT enthusiasts or anyone who’s dared to venture into the NFT universe, the term “minting” pops up like an unavoidable signpost. While it might evoke images of a grand, old-world mint churning out gleaming coins, in the digital sphere, the concept of minting takes on a new, fascinating persona.

Minting in the NFT world is the transformative process of creating a new, unique NFT. It’s like an artist gently dabbing paint on a canvas or a writer weaving a world with words, except here, you’re giving birth to a digital asset on the blockchain. This creation process imbibes the NFT with specific attributes, properties, and metadata, essentially shaping its digital DNA. As soon as the NFT is minted, it’s a distinctive entity, etched forever on the blockchain, ready to be traded, collected, or simply admired.

Each minting is a digital artistry moment, the first step on the road to creating your own Sistine Chapel in the ether, producing digital masterpieces that traverse and light up the virtual world.

Gas Fees

Now, let’s shift gears and navigate the term “Gas Fees.” Although it may sound like something associated with your vehicle or energy bill, in the context of Ethereum and NFTs, gas fees represent the price of computational transactions.

Each action on the Ethereum network, from minting and trading NFTs to initiating smart contracts, demands computational resources. This processing is done by miners, whose role is to validate and record transactions on the blockchain. Like the toll you pay on a busy highway, these miners need compensation for their work – and that’s what we refer to as ‘gas.’

Similar to how rush hour can cause toll prices to spike, gas fees are also susceptible to the congestion levels of the network. When the network is bustling with activity, gas fees climb. Conversely, during periods of lower demand, they recede. This dynamic pricing model forms a crucial component of the Ethereum ecosystem, impacting everyone dabbling with NFTs.

Understanding these integral terms—minting and gas fees—is akin to learning the rules of the road in your NFT journey. So strap in and prepare for an exciting adventure through the intricate and fascinating highways of the digital asset landscape!

Digital Wallets

In the physical world, you have a wallet to store your cash, cards, and IDs. In the virtual realm of NFTs, digital wallets serve the same purpose – only here, they hold your precious non-fungible tokens and cryptocurrencies. These wallets are essentially encrypted digital lockboxes, storing the unique cryptographic keys needed to access your digital assets. In other words, they are your personal, highly secure vaults in the wide world of the blockchain.

What’s more, these digital wallets aren’t just storage spaces; they’re also your transaction enablers. Whether you want to buy a digital art piece, sell an NFT, or trade digital tokens, you’ll need a digital wallet. They are your pocket-sized, ultra-secure treasury for the digital age, acting as your passport and your bank in the NFT marketplace.

Smart Contracts

Smart Contracts are the backbone of the NFT world, quietly running the show from behind the scenes. These are self-executing contracts with the terms directly written into lines of code. Picture them as diligent, incorruptible digital clerks who always get the job done—be it verifying transactions, executing transfers, or enforcing contract rules. 

The beauty of smart contracts lies in their autonomy and precision. There’s no room for human error or bias. Everything is predetermined and executed according to the coded rules, making the transfer and trading of NFTs a smooth, transparent process. Smart contracts are truly the invisible conductors, orchestrating the harmonious symphony of NFT transactions.


Royalties in the NFT realm are more than just fees; they’re a symbol of long-lasting recognition and reward for artists. Every time an NFT changes hands, a percentage of that transaction—pre-determined as royalty—goes back to the original creator. This ensures that artists continue to benefit from their work long after the initial sale.

In a traditional art marketplace, artists often receive a one-time payment for their work, but in the digital NFT market, royalties ensure sustained earnings. The more their artwork is appreciated and traded, the more they earn, fostering a more equitable and profitable space for artists worldwide.


Metadata in the NFT universe is like the DNA of a living organism. It’s the unique set of data that gives an NFT its identity, describing its properties, origin, and ownership. Just like DNA contains all the information about an organism, from its eye colour to its height, metadata holds the key information about an NFT.

This can include a broad range of details, such as the name of the digital asset, its creator, creation date, and a detailed description. Moreover, it can include unique attributes that differentiate one NFT from another. In essence, metadata is the indelible imprint on an NFT that verifies its uniqueness and authenticity in the digital crowd. It’s the ID badge that an NFT wears with pride in the digital art gallery of the blockchain.


Ethereum Request for Comment 721, better known as ERC-721, is the big daddy of the NFT standards. It is the original protocol used for creating non-fungible, or unique, digital assets on the Ethereum blockchain. Each token minted under ERC-721 carries a distinct value and set of attributes, ensuring its uniqueness in the universe of tokens.

Like unique artworks in a gallery, no two ERC-721 tokens are the same. This standard ushered in the concept of tokenizing unique assets, paving the way for digital art, collectibles, virtual real estate, and more. ERC-721 can be thought of as the birth certificate of the NFT universe, a blueprint that revolutionised the concept of digital asset ownership.


ERC-1155 is the Swiss army knife in the toolkit of Ethereum token standards. Why? Because it allows for the creation of both fungible (identical) and non-fungible (unique) tokens. It’s like having the best of both worlds—ERC-20 and ERC-721—all rolled into one efficient standard.

This semi-fungibility opens up new possibilities, like owning multiple copies of an identical digital poster or single, unique pieces of digital art. It’s an evolution in the Ethereum token standards, providing greater versatility and efficiency in the creation and management of digital assets.


Provenance is the Sherlock Holmes of the NFT universe, tracing the lineage of a token right back to its creation. In the art world, provenance refers to the documented history of an artwork, essential in establishing its authenticity and value. In the realm of NFTs, provenance performs the same role, but with even more precision and transparency, thanks to the power of blockchain technology.

Every creation, transaction, and transfer of an NFT leaves an indelible mark on the blockchain. This transparent and immutable record acts as the ultimate provenance document, revealing the entire ownership history of an NFT. This verifiable authenticity is one of the key attractions of NFTs, boosting buyer confidence and enhancing the value of digital assets.

Cryptographic Signature

In the physical world, a handwritten signature is a personal endorsement or proof of identity. In the digital domain of blockchain and NFTs, cryptographic signatures play the same role, albeit with far more security and complexity. 

A cryptographic signature is a mathematical mechanism that allows someone to prove their identity or validate a piece of information. Just as a wax seal was used to verify the authenticity and integrity of a letter in the past, cryptographic signatures validate blockchain transactions, ensuring they are secure and tamper-proof. 

When a creator mints an NFT, they sign it with their unique cryptographic signature. This signature is then permanently recorded on the blockchain, serving as a robust proof of authenticity and originality for the NFT. It’s the invisible seal of trust that fortifies the world of NFTs, ensuring every digital asset is precisely what it claims to be.

IPFS (InterPlanetary File System)

The InterPlanetary File System, or IPFS, is more than just a fancy acronym—it’s a revolutionary protocol designed to turbocharge the web while also making it safer and more open. Unlike traditional file storage methods that rely on centralised servers, IPFS takes a peer-to-peer approach, where each file and all the blocks within it are given a unique fingerprint, known as a cryptographic hash.

What makes IPFS special in the context of NFTs? The answer lies in decentralisation. Given the immutable and unique nature of NFTs, the data attached to them needs to be stored securely and permanently. Here, IPFS comes to the rescue, providing a decentralised storage solution, thereby ensuring that your digitally owned piece of art or collectible is preserved securely, free from the risks of data loss or corruption. IPFS and NFTs are, therefore, the perfect marriage of decentralised tech, each enhancing the power and potential of the other.


Think of the first NFTs on the Ethereum blockchain, and Cryptopunks come to mind. These are not your everyday digital characters, but 10,000 uniquely generated 24×24 pixel art figures. Each punk has its own type, features, and accessories, making it distinct from the rest.

Created by software developers Matt Hall and John Watkinson, Cryptopunks sparked the beginning of the NFT revolution. These pixelated personas have now become digital collectibles, with some fetching prices in the millions. Cryptopunks have set the stage for the explosion of NFT art and have become iconic figures in the realm of digital assets.


Cryptokitties is a name that brings a smile to every NFT enthusiast. It’s a blockchain-based game that allows players to adopt, raise, and trade virtual cats, which are represented as NFTs. But these aren’t just any cats. Every Cryptokitty is unique, having its own set of attributes, or “cattributes” if you will.

The game uses the ERC-721 standard for its kitties, ensuring that each one is one-of-a-kind, owned by a specific person, and stored on the Ethereum blockchain. The kitties can be bought, sold, or bred to create new kitties, each with their own unique attributes. Cryptokitties took the Ethereum network by storm when it was launched in 2017 and has since become synonymous with the fun and potential of NFT gaming. They showcase how NFTs can create new, engaging experiences and open up a world of digital ownership in gaming.

Decentralised Finance (DeFi)

Emerging from the innovative expanse of blockchain technology, Decentralised Finance, popularly known as DeFi, is radically transforming the conventional financial structures. It is a disruptive model that employs decentralised networks and open-source software to provide various financial services. A far cry from the conventional banking system, DeFi promotes a more egalitarian financial landscape, promoting universal accessibility and eliminating the need for intermediaries.

What is transformative about DeFi is its potential to democratise finance. Traditionally, financial services, from borrowing and lending to insurance and asset trading, are confined by numerous limitations, including geographic restrictions and substantial third-party dependence. DeFi, backed by Ethereum’s blockchain technology, dismantles these boundaries, fostering a more inclusive and transparent financial ecosystem.

From an NFT enthusiast’s perspective, DeFi presents intriguing possibilities. Imagine having the ability to mortgage your NFTs and acquire loans, or the prospect of lending your digital assets and earning interest. These instances signify the tremendous potential that DeFi injects into the realm of NFTs and digital assets.

Decentralised Autonomous Organizations (DAOs)

Decentralised Autonomous Organizations (DAOs) are a unique concept birthed from blockchain technology. DAOs are essentially organisations steered by smart contracts rather than a centralised authority. The rules of operation are coded into a collection of smart contracts, with governance typically conducted through a consensus voting system amongst its token holders.

DAOs are redefining the role of community in the NFT sphere. They allow for the collective ownership and management of NFTs, thereby facilitating shared ownership of high-value assets that individual members might not afford independently. Furthermore, DAOs could govern virtual worlds inhabited with NFTs or establish guidelines for NFT creation and trading within a particular community. Essentially, DAOs are pioneering a shift towards collective decision-making and ownership in the NFT space.


Tokenomics, a fusion of ‘token’ and ‘economics,’ is the study of the economic systems that drive the creation, distribution, and management of digital tokens. It delves into the intrinsic design and functionalities of cryptocurrencies within their broader ecosystem, including the determinants of their value, their supply mechanisms, and the incentives for users.

A solid grasp of tokenomics is integral for NFT enthusiasts and investors. For instance, it can aid in comprehending the pricing mechanisms behind certain NFTs, decipher what influences their value, and anticipate potential shifts in their value over time. As such, tokenomics forms a crucial component of the knowledge portfolio of every NFT investor or enthusiast, enabling them to navigate the dynamic digital asset landscape with an informed perspective.
