NFT tokens- 7 of the biggest projects.

NFT tokens are conquering the collectible items markets. During the last months there has been increased interest in NFTs. Therefore we prepared for you the list of the most interesting examples of their possible uses. 

NFT tokens use a special technology called a blockchain that certifies a digital asset to be unique and therefore not interchangeable. Tokens have been recently increasingly used in such key areas as IoT or supply chains. The NFT market value tripled in 2020, reaching more than $315 million.

NFT tokens are non-fungible, which means that each token in a given system is unique. Tokens like that do not have a standard value and often do not allow for the equivalent exchange of one for another. Each token has distinct, unique ownership or identity information. 

NFT tokens basic assets are: 

  • they are impossible to counterfeit
  • they can be moved
  • they retain ownership rights

NFT tokens - the biggest projects

NBA Top shot

The outcome of the cooperation between NBA and Dapper Labs company, in the simplest terms, is an internet platform for exchanging virtual trading cards. At NBA Top shot, basketball fans can buy and sell "moments" video clips from the last seasons of the competition that exist as NFT tokens on the Blockchain.

This is not the first time when NFT tokens have been used by a professional sports League, however, it is without a doubt the biggest one. CryptoSlam estimates that up until to now, the total value of all transactions between users has already reached $ 370 million. 

Axie Infinity

Axie Infinity is a gaming platform that, similarly to Decentraland, allows you to purchase a virtual ground in the form of an NFT token. In February this year an anonymous user with a nickname Flying Falcon bought 8 land grounds in the world of Axie for 1,5 million dollars.

"This largest digital ground sale in history represents a significant development in the short historyof NFT," said the seller in an interview for CoinDesk. "It is virtual economies that will be the new frontier for an increasingly digital world."

The demand for virtual grounds is steadily growing. This year, the average price paid for a plot in Decentraland was $ 2,703 - over three times more than in 2020. However, on another platform of this type - Cryptovoxels, the average value of the land has quadrupled during this time. 

Companies that operate on a traditional real estate market are slowly becoming interested in NFT virtual tokens. A good example is the enterprise called Republic Real Estate which operates in the housing market and opened for investors who are willing to buy a virtual ground. The enterprise is planning to buy a ground in several internet platforms and then reshape them for virtual hotels and shops in order to increase their value among enthusiasts.

“Real estates in the current world are very uncertain’’- said Janine Yorio, head of Republic Real Estate. “Residential prices are extremely high. However, offices and hotels are empty. It seems that virtual grounds are isolated from many real-life dangers’’.

King of Leons - music album released as NFT

Their eighth studio album, When You See Yourself, was released in March this year in the form of a NFT token. This is the first time that NFT tokens have been used by artists with such high visibility. The sale of tokens, in which the company  Yellow Heart was represented, ended on March the 19th, generating over $ 2 million in revenue. 

The NFT tokens released by the band in many ways resemble the typical merche of artists: they guarantee access to future concerts, covers or a limited vinyl edition. The applied technology makes NFT tokens unique. Because of the fact that NFT tokens use smart contracts, a set of rules may be taken into account by their creator to determine what should happen when an NFT is used or changes hands. It is precisely this aspect of NFT tokens that is the most valuable for the music industry.

Owing to NFT tokens , musicians can retain direct ownership of the rights to the song and collect royalties for playback and sales without the intervention of intermediaries.

Nike CryptoKick

NFT tokens are taking the collectibles market by storm. Their using owing to a footwear industry should be no reason to wonder, especially as in the 21st century, shoe collecting permanently entered the mainstream.

The industry giant- Nike joined in the trend registering the patent as a solution named CryptoKick in 2019. It is a system which enable to create and exchange cryptographically secured digital assets in the form of virtual shoes that can be linked to their physical counterpart in the real world.

 In the meantime, the whole project is shrouded in mystery, but it is already known today that is supposed to allow for simultaneous receipt of both versions of shoes; digital and physical at the time of purchasing the actual pair. 

Gucci AR sneakers 

In the fashion industry, where uniqueness and originality have always been of fundamental importance, it seems to be the perfect environment for NFT tokens. Therefore nowadays the biggest brands are investing in the development of the technology. 

Among them was the Gucci fashion house, which launched a series of augmented reality (AR) shoes in the form of NFT. The pair costs less than $ 12, and to make it possible to sell it, the company hired the Belarusian company Wanna, which has also collaborated with brands such as Puma and Reebok. 

"In five, maybe 10 years, a relatively large proportion of fashion brands' revenues will come from digital products," said Wanna CEO Sergey Arkhangelskiy, The Business of Fashion magazine.

,,Our aim as a company is to replace photos of products with something which is much more engaging and much more like shopping offline’’.

Beeple and Christie’s auction

Mike Winkelmann, known professionally as Beeple, is an American digital artist, graphic designer who began to explore and use the benefits of blockchain technology. The artist has been selling his works in the form of NFT tokens for years. However, it was the auction of his work at the Christies auction house that allowed him to become the author of the third most expensive cannon which was sold during the artist's lifetime in history.

The winner of the auction acquired ‘’EVERYDAYS: THE FIRST 5000 DAYS”  as a NFT token for nearly 70 million dollars. Thus, Christies became the first auction house to put a NFT token up for auction. In addition, the payment was made in Ethereum which is totally new for such an institution. 

The first tweet of Twitter's CEO is sold 

Last month, Twitter's CEO and founder sold his first tweet as NFT for 2.9 million dollars. Soon, the entrepreneur was joined by other personalities from the world of business and entertainment, even Elon Musk was close to sell his entry.

"This is not just a tweet!" - the action winner Hakan Estavi, CEO of Bridge Oracle said, "I think that ,after many years, people will realize the true value of this tweet, equal to the portrait of the Mona Lisa."

What is Account Abstraction?


10 Nov 2023
What is Account Abstraction?

Account abstraction is a new way of thinking about how users interact with blockchains. Instead of using traditional externally owned accounts (EOAs), account abstraction allows users to create and manage their accounts using smart contracts. This has a number of potential benefits, including improved security, enhanced privacy, and increased flexibility.

What is account abstraction?

Account abstraction is a concept that, at its core, aims to simplify the user's interaction with blockchain networks. It is a transformative approach that seeks to mask the technicalities of blockchain operations from end-users. It is making transactions as straightforward as sending an email. Account Abstr. allows users to interact with the blockchain without worrying about the underlying technical details.

How does account abstraction differ from the traditional model?

In the traditional account model, each user has an EOA. EOAs are controlled by private keys, which must be kept secret in order to protect the user's funds. Acc. abstraction allows users to create and manage their accounts using smart contracts.

Historical Context

The journey towards acc. abstraction began with the first generation of blockchain technologies, characterized by their "one-size-fits-all" approach to account management. Bitcoin, for instance, introduced the concept of accounts and transactions in a form that was accessible to tech-savvy individuals but remained perplexing to the layperson. Ethereum expanded on this by introducing smart contracts, which opened the door to programmable transactions but did not alter the fundamental account structure. The idea of acc. abstraction has been discussed in the Ethereum community for several years as a part of various Ethereum Improvement Proposals (EIPs), particularly as a feature to be potentially implemented in Ethereum 2.0. It is a direct response to the need for a more versatile and user-centric design that can cater to a broader audience and spur the widespread adoption of blockchain technology.

The Technicalities of Account Abstraction

Account abstraction is not merely a theoretical construct but a technical innovation with specific mechanisms underpinning its operation. In essence, it alters the way transactions are initiated and executed within a blockchain network.

How Account Abstraction Works

Under traditional blockchain models, initiating a transaction involves an externally owned account (EOA) signing a transaction with a private key. This transaction is then broadcast to the network for validation and inclusion in the blockchain. Account abstraction, however, replaces this process with a more flexible one. Here, every account is a smart contract, and transactions are messages sent through these contracts. These smart contracts can encode complex rules for transaction validation, beyond what EOAs can do, such as multi-signature requirements or conditional transactions based on certain triggers.

The technical crux of account abstraction lies in the smart contract’s ability to define its own conditions for transaction execution. This means that user accounts can have unique security protocols or automated operations without the user needing to understand the underlying smart contract code.

The Benefits of Account Abstraction

The implications of account abstraction are profound, offering a range of benefits that can enhance the blockchain experience for users and developers alike.

Improved User Experience

One of the most significant advantages of account abstraction is the improvement it brings to user experience. By abstracting away the complexities of key management and transaction rules, it presents a more intuitive interface for users.

Enhanced Security Features

Account abstraction also allows for the implementation of advanced security measures. Since each account can define its own logic, users can tailor their security settings to their specific needs. For instance, one might set up an account that requires additional verification for transactions exceeding a certain value or restricts withdrawals to certain addresses.

Future Implications

The future implications of account abstraction are vast. As the technology matures, it could become a standard feature of blockchain networks, potentially making the current distinction between user accounts and smart contracts obsolete. This could lead to a new wave of blockchain applications that are both powerful and accessible, bringing us closer to the vision of blockchain technology as a seamless part of everyday life.

Challenges and Considerations

Technical Limitations

One of the primary technical challenges of Acc. abstraction lies in its integration with existing blockchain protocols. Current networks are optimized for the EOA model, and introducing a new account structure necessitates significant changes to the core protocol. This includes modifications to the way transactions are propagated in the network, how gas fees are calculated, and how the state of the blockchain is managed. Ensuring that these changes do not compromise the network's performance or security requires careful planning and extensive testing.

Compatibility with Current Systems

Another consideration is the compatibility of account abstr. with the vast ecosystem of existing blockchain applications and services. Wallets, exchanges, and other services have been built around the traditional account model. Transitioning to an acc. abstraction model will require these services to update their infrastructure, which may be a complex and resource-intensive process. Furthermore, there is a need for standardization across the industry to ensure that different implementations of account abstr. can work seamlessly together.


Acc. abstraction represents a significant leap forward in the quest for a more user-friendly blockchain experience. By streamlining the transaction process and offering enhanced security features, acc abstraction has the potential to make blockchain technology more accessible to a broader audience. However, the path to widespread adoption is not without its obstacles. Technical challenges and compatibility issues must be carefully navigated to integrate it into the existing blockchain landscape.
