Soulbound tokens (SBT) are non-transferable, publicly verifiable digital tokens that can serve as a type of CV for web3 users, displaying a person's memberships, credentials, and affiliations.

The concept was inspired by the popular video game World of Warcraft, which rewarded users with'soulbound' items that could not be traded or sold to other characters.


In their whitepaper, Glen Weyl, Puja Ohlhaver, and Vitalik Buterin described SBTs as a way to "eschew today's hyper-financialization" of the web3 ecosystem in order to transition to a Decentralized Society "encoding social relationships of trust."

Soulbound Tokens (SBTs) are a type of non-transferable digital asset designed to represent a person's identity, achievements, or affiliations on the blockchain. Unlike traditional tokens that can be traded or sold, SBTs are permanently tied to the owner's wallet, making them unique identifiers.

SBTs can be used for various purposes, such as verifying educational credentials, professional certifications, or membership in organizations. They enhance trust and transparency by providing a verifiable record of someone's accomplishments without the risk of forgery or fraud.

In the context of decentralized finance (DeFi) and Web3, SBTs could play a crucial role in reputation systems, social profiles, and even governance, ensuring that digital identities are authentic and cannot be easily manipulated or duplicated.
