# 3.4. sNFT Overview

WinFi has both gambling and metaverse entertainment elements, and sNFT is a specific representative of WinFi's metaverse entertainment. sNFTs can be traded on OpenSea and have both collectible and store-of-value characteristics.

  All sNFTs are obtained from sNFT treasure boxes. The chance of obtaining a rare sNFT from an sNFT treasure box is 4.7%, while the chance of obtaining a common sNFT is 95.3%.

  The following table lists the NFT attributes of WinFi, for which WinFi has designed a contract invocation framework to facilitate third-party developers in calling and extending these attributes:

The main attribute contract among these attributes was completed by WinFi at the start-up, while the other four secondary attributes and five reserved attributes are activated through contracts deployed by users and authorized to third-party developers. These attributes can be viewed and integrated into WinFi through the sNFT Token ID in the attribute contract.
