Coined by Vitalik Buterin, Soulbound Tokens (SBTs) are permanent and non-transferable NFTs. Unlike typical NFTs, SBTs remain bound to their original account, making them useful for representing identity, credentials, and other achievements.
Technical Implementation of SBTs on Sui
To create non-transferable NFTs on Sui, developers can use Sui's object-centric data model. The primary step is to remove the store ability from the NFT structure, preventing free transfer of the token. Custom transfer rules provide fine-grained control over how and when the token can be transferred, maintaining the flexibility needed for specific use cases.
SBT Evolution on Sui
One key feature of SBTs on Sui is the ability to incorporate dynamic properties through Sui's dynamic fields, allowing NFT attributes to change post-creation. This makes SBTs evolve based on user actions or status changes, greatly enhancing their utility and relevance over time.
