SFT Product – VeChain ToolChain™ Help Center

Semi-fungible token ("SFT") takes the features of Non-fungible Token ("NFT") and Fungible Token ("FT") into it.

SFT is best used for a generic product type, each product with unique features. The unique features of a product are tokenized as NFT while the generic product type (i.e. replica) of the said products is tokenized as FT.

For example, in online games, a hat is a generic product type (i.e. FT component), and the various unique features to a hat is the NFT component.

Key escrow is the turnkey solution provided by VeChain ToolChain^TM. The enterprises can create new users on the webpage or through API to help the user provide private key escrow services.

Minting/issuing SFT requires 2 elements -- your SFT smart contract address and the recipient's wallet address.
