Everything You Need to Know About Soulbound Tokens

In the world of blockchain and NFTs, innovation never sleeps. Among the latest entrants to this dynamic space are Soulbound Tokens (SBTs), a term that’s quickly gaining recognition and sparking curiosity among enthusiasts. But what exactly are Soulbound Tokens, and why are they becoming a hot topic in the realm of digital assets? In this thought leadership piece, we aim to unravel the mysteries surrounding Soulbound Tokens, exploring their origins, significance, and the exciting developments they promise for the future of blockchain technology.

What Are Soulbound Tokens?

Soulbound Tokens, often referred to as SBTs, are a novel type of blockchain-based digital asset. At their core, they are non-fungible tokens (NFTs) with a unique twist. Unlike traditional NFTs that represent ownership of a digital item, artwork, or collectible, Soulbound Tokens take this concept a step further. When you own an SBT, you’re not just acquiring a digital asset; you’re forming a unique, irrevocable connection with it. In essence, SBTs are imbued with a piece of your identity, creating a symbiotic relationship between owner and token.

Some of our finest minds have been addressing the topic of digital and decentralized IDs (DID) for some time, including well-known individuals like Jack Dorsey and Vitalik Buterin, the co-founder of Ethereum. The concept of soulbound tokens (SBT), which serve as non-transferable non-fungible tokens (NFT) and can assist in symbolizing a person’s identity and accomplishments on Web3, has been put out by Buterin.

By the end of this year, Buterin wants to have the Soulbound tokens (SBTs) ready for early use on the Ethereum blockchain. The goal of his bigger strategy is to establish a “decentralized society” by 2024.

The Significance of Soulbound NFTs

The Significance of Soulbound NFTs

Soulbound NFTs, also known as “Soulbound Non-Fungible Tokens,” represent a unique and significant development in the world of blockchain technology and digital assets. These NFTs are typically associated with virtual worlds, video games, and other digital ecosystems where they offer various advantages and unique features. Here are some facts and figures that highlight the significance of Soulbound NFTs:

  • Ownership and Scarcity: Soulbound NFTs are designed to be owned by a specific character or entity within a virtual world or game. This ownership is recorded on the blockchain, ensuring the scarcity and uniqueness of the item. In some games, only a limited number of such NFTs are created, adding to their exclusivity.

  • Interoperability: Soulbound NFTs can often be used across multiple games or virtual worlds within the same ecosystem. This interoperability allows players to take their digital assets with them as they explore different environments, enhancing the user experience and investment value.
  • In-Game Assets: These NFTs often represent in-game assets such as characters, weapons, skins, or virtual real estate. They can have real utility within the game, impacting gameplay, aesthetics, and overall experience.
  • Economic Value: The economic value of Soulbound NFTs can be substantial. Some of the most sought-after items have sold for thousands or even millions of dollars. For example, in Decentraland, a virtual world, a virtual estate sold for over $900,000 in 2021.


  • Ownership Control: Players have complete ownership control over their Soulbound NFTs. This means they can trade, sell, or use them as they see fit, as long as the game’s rules allow it.
  • Collectibility: Just like physical collectibles, Soulbound NFTs can be collected by enthusiasts and investors. Rarity, aesthetics, and historical significance play a significant role in their collectible value.

  • Development Opportunities: The existence of Soulbound NFTs has created new opportunities for game developers and content creators. They can design and mint NFTs to enhance the gaming experience and monetize their creations.
  • Challenges and Concerns: While Soulbound NFTs offer exciting possibilities, they also raise concerns about environmental impact due to blockchain energy consumption, regulatory issues, and the potential for scams or fraud in the NFT market.
  • Market Growth: The market for Soulbound NFTs has seen significant growth. The market size for Non-Fungible Tokens (NFTs) was estimated at USD 16 billion in 2021 and is anticipated to increase from USD 21.39 billion in 2022 to USD 212 billion by 2030, expanding at a CAGR of 33.7% over the forecast period (2023-2030). 

Soulbound NFTs represent a convergence of blockchain technology, gaming, and digital asset ownership. Their significance lies in the unique ownership model, interoperability, economic value, and community engagement they bring to virtual worlds and digital ecosystems. However, it’s important to note that the NFT space is rapidly evolving, and market dynamics can change quickly, so staying informed about the latest developments is essential for anyone interested in this space.

Soulbound Token Development

Soulbound Token Development

Creating Soulbound Tokens involves a sophisticated process that combines blockchain technology with elements of identity verification. Here’s a simplified overview of the development process:

  • Creation: An artist or creator mints an SBT by embedding a piece of their own identity into the token. This is often done through cryptographic techniques, ensuring the bond is secure and tamper-proof.

  • Ownership Confirmation: The potential owner undergoes an identity verification process to confirm their eligibility to own the Soulbound Token. This step helps maintain the integrity of the bond between the owner and the token.
  • Token Transfer: Once the Soulbound Token is in the owner’s possession, it cannot be transferred or duplicated. The bond is permanent and unique to the individual.

Limitations of Soulbound Tokens

The lack of 100% tested methods to restore lost Souls is one of several issues with the potential adoption of soulbond tokens in the future. Numerous ways to recover Souls are suggested in the whitepaper by Vitalik Buterin, Glen Weyl, and Puja Ohlhaver, but they still need to be tried out and accepted. 

In order to recover a Soul’s private keys, for instance, a community recovery model might need the approval of a person from a qualified majority of a (random subset of) Soul’s communities.

Another issue is that a community based on reputation might develop into a social credit system where those with higher ratings receive greater benefits and others could be blacklisted. This presents ethical issues and prevents individuals from growing.

Real-life Applications of Soulbound NFT Tokens

Real-life Applications of Soulbound NFT Tokens

Soulbound NFT tokens are a relatively new concept, and their specific applications are not widely documented. However, the concept of Soulbound NFTs implies a connection between a digital asset and a real-world item or experience. Since NFTs are highly versatile, it’s possible to imagine various real-life applications for Soulbound NFT tokens. Here are some potential examples:

  • Professional Documentation 

These are more like how we exchange information about ourselves on our CVs, to put it simply. However, in this instance, more than one Soul may issue or vouch for it. A corporation might offer a letter of reference for a worker as SBT, for instance.

As a result, when colleges begin offering degrees as SBTs and employers start awarding SBTs to employees, these credentials will make it more difficult for scammers to pass themselves off as someone else. The purpose is to strengthen individuals’ social identities by personalizing them with one-of-a-kind, non-exchangeable badges.

  • Digital ID and Memberships 

We can also use soulbound tokens to represent our identification documents and membership cards. Any type of public place and facilities including gyms, libraries, sports clubs, and others, can give members SBTs so they can keep tokens in their wallets. Users will have lifetime access to their data and visits as well as be able to maintain these tokens.

Additionally, users will find it easier to avoid always carrying a physical wallet stuffed with cards by storing all of their IDs inside a single digital wallet.

  • Attendance Recording

In today’s world, a Proof of Attendance Protocol (POAP) offers a use case that is very similar to this one. A POAP is an NFT that businesses employ as part of their loyalty programs and marketing campaigns, whereas the primary function of SBTs is to confirm that the user actually attended an event.

  • Credit Reports

Users can provide lenders access to their credit profile, which will be represented by SBTs if they need to obtain a loan. Lenders will then be able to rapidly assess the user’s credit history and either approve or deny the loan based on how prompt the user has been with prior payments.

  • Management of Medical Records

When someone needs medical attention, they don’t necessarily need the added stress of finding a doctor, outlining their medical history, and dealing with an insurance company. Most of these issues can be avoided if medical records are kept in SBTs by physicians and patients.

Patients will be in complete control of and have access to their medical records, and they will be able to rapidly confirm their identification and give doctors their medical background. This is crucial when a patient changes hospitals and doctors and applies for insurance. They won’t have to print out tangible copies of their documents thanks to SBTs. Instead, with a few clicks, customers can provide (and remove) access to their data.
