A Semi-Fungible Token (SFT) is a type of digital asset that combines characteristics of both fungible and non-fungible tokens. It can represent items that may start as interchangeable but can gain unique properties over time.Initially, SFTs can function like fungible tokens, meaning they can be exchanged on a one-to-one basis. However, they can also evolve into unique entities, similar to non-fungible tokens (NFTs), depending on certain conditions or events.For example, a ticket to an event might be an SFT. Before the event, multiple tickets can be traded and valued as equal. After the event occurs, specific tickets can gain unique attributes (like a VIP experience) that make them distinct and non-fungible.This flexibility allows SFTs to offer a versatile approach to asset representation, making them useful in various applications like gaming, event ticketing, and more. They enable creators and users to capture the benefits of both fungibility and uniqueness in a single asset.
