A semi-fungible token (SFT) is a type of digital asset that combines the properties of fungible and non-fungible tokens (NFTs). SFTs display partial interchangeability within a token class, as opposed to fungible tokens, which are identical and interchangeable, and NFTs, which represent unique goods. Each SFT has its own distinct set of characteristics or qualities, allowing for differentiation and customization. SFTs are widely utilized in applications that need token variations or editions, such as limited editions of digital collectibles or tokenized assets with different properties.

Fungible Tokens

Fungible tokens and assets are replaceable and not one-of-a-kind. We can use the US dollar as an example. $1 is worth the same in every American city. One Ethereum is equal to one Ethereum when using a fungible token. Therefore, the requirement of no value loss is a point. A token’s (or currency’s) ability to be swapped for or replaced with another of its kind of tokens with no loss in value is known as fungibility.

Fungible tokens have the following features:

  • Divisible: The same tokens can be divided.
  • Non-unique: There is nothing special about the $1 bill; there are billions of the same bills all across the world.
  • Interchangeable: It is instantly replaced by a token or coin of the same value.

Examples: the US dollar, Euro, Bitcoin, Ethereum, and others.

Non-Fungible Tokens (NFTs)

Non-fungible tokens (NFTs) are distinctive digital assets that serve as proof of ownership or validity for a particular good or piece of content. Each NFT has unique features and cannot be swapped one-for-one for another token, in contrast to fungible tokens. Digital valuables, works of art, virtual properties, and other distinctive goods are frequently represented by NFTs. They provide scarcity, provenance, and verifiable ownership using blockchain technology, adding a new dimension of value and ownership to the digital world.

Because NFTs are kept on a blockchain, each token has certain characteristics:

  • Indivisible: You can’t buy parts of NFTs
  • Indestructible: You can’t delete or remove it
  • Immutable: Once data is stored, it cannot be changed.
  • Verifiable: Because NFTs are recorded on public blockchains, their origin, and ownership can be easily traced by anybody at any moment.

Examples: In-game objects such as a shield or sward, digital and non-digital collectibles such as a sports card, domain names, event tickets, a plot of land in a sandbox game, etc.

Semi-Fungible Tokens (SFTs)

Semi-fungible tokens (SFTs) include elements of fungibility and non-fungibility. SFTs are somewhat interchangeable among members of the same token class, but they also have special qualities that set them apart from one another. Variations in scarcity, color, or other distinctive characteristics might be included in these characteristics. SFTs are frequently utilized in applications where customization and differences within a certain token class are sought, such as tokenized assets with varied properties or limited editions of digital collectibles.

Examples: gift cards, tickets, vouchers, in-game currency, etc.

So, what does an SFT mean?

Semi-Fungible Tokens (SFTs)

SFTs are relatively new to the world of crypto tokens, which is why they modeled themselves after their elders — fungible and non-fungible tokens — in order to adapt to changing conditions. SFTs were first seen as fungible tokens that could be swapped for other SFTs of the same value. A token representing a valid ticket to a rock event, for example, would have the same value as an identical ticket with the same expiration date and hence be interchangeable.

The main feature that distinguishes these tokens as “semi-fungible” is that fungible tokens lose their face value when redeemed. They become non-fungible once they lose their exchangeable value. SFTs are popular in the gaming industry and the metaverse. They also give transitional fungibility. In this regard, SFT offers the same advantages as NFT. SFTs, like NFTs, provide rapid transactions.

After selling or exchanging the item, SFT owners are not permitted to do so again. SFTs are useful when other fungible tokens become worthless. Who is able to utilize the SFTs? Organizations, businesses, and institutions. SFTs may more easily add new features and components since they are constructed on the Ethereum blockchain.

Semi-fungible tokens get around the limits of both fungible (ERC-20) and non-fungible (ERC-721) tokens, as well as the “disagreement” between various standard tokens.

The key feature of fungible tokens is their irreversible transactions. It basically implies that if you transmit coins to the wrong address, you will lose them.

Semi-fungible tokens, on the other hand, are constructed on smart contracts that allow for the tracking of errors. As a result, incorrect token transfers are reversible.

Semi-fungible tokens support batch transfers, but NFTs do not. Many SFTs can be transferred in a single transaction, resulting in cheaper gas prices and expenditures.

How to create semi-fungible tokens?

The SFTs are created using Ethereum’s ERC-1155 standard. ERC1155 is mostly used for the creation of non-fungible tokens (NFTs).

The ERC-1155 standard was developed in 2017 by blockchain game companies EnjinHorizon Games, and The Sandbox as a hybrid of the ERC-20 (fungible token) and ERC-721 (non-fungible token) standards.

SFTs are notably useful in the gaming industry, where fungible components such as in-game cash coexist with non-fungible objects such as trinkets and weaponry.
