Semi-Fungible Tokens (SFTs) are a specialized class of blockchain tokens that exhibit both fungible token (FT) and non-fungible token (NFT) properties at different stages of their lifecycle. Typically, SFTs are interchangeable like FTs during certain periods, but under specific conditions, they become unique assets, much like NFTs.
For example, an event ticket can be freely exchanged before use, but after entry, it transforms into a one-of-a-kind NFT with commemorative value. In gaming, a generic item may be traded in bulk, but once upgraded, it becomes a unique piece of equipment.
Unlike traditional cryptocurrencies such as BTC, ETH, and other FTs or NFTs, SFTs are innovative because their state can change. While fungible, they support batch processing and efficient transfers. Once non-fungible, they gain uniqueness and collectible value.
As a result, SFTs offer significant advantages in on-chain transaction efficiency, lower transfer costs, and greater asset flexibility. For instance, the ERC-1155 standard allows for batch transfers, reducing gas fees and improving transaction speed.
One of the most important technical advancements for SFTs in recent years is the adoption of the ERC-3525 standard within the Ethereum ecosystem. Developed by Solv Protocol, this standard enables more flexible asset representation and quantity control for SFTs across multiple dimensions, including ID, slot, and value. ERC-3525 is positioned to become a foundational standard for financial NFTs and complex asset tokenization.
By 2025, as demand for more efficient asset types grows in the blockchain market, SFT-related standards are attracting increasing attention from developers and project teams. Applications are expanding into DeFi, gaming, ticketing, digital collectibles, and other sectors.
While SFTs have not experienced the explosive price surges seen with NFT art collections, their value is steadily building from an infrastructure perspective. The core investment logic centers on functionality and real-world application. Once a use case scales—such as blockchain gaming, on-chain event ticketing, cross-chain assets, or RWA tokenization—the value of SFTs becomes clear.
When considering investments in the SFT ecosystem, focus on the following areas:
Semi-Fungible Tokens are currently used primarily in the following areas:
SFTs remain an emerging category of blockchain assets. Compared to NFTs and FTs, they are at an earlier stage in market education, standardization, and secondary market liquidity. Before investing, pay close attention to the following risks:
Nonetheless, from a macro perspective, Semi-Fungible Tokens offer long-term value potential as an asset class bridging the gap between FTs and NFTs. They are likely to play a pivotal role as Web3 applications expand across multiple scenarios.
