{"version":"1.0","type":"rich","title":"Gist 565d71987d2e83d17e094c9611c50bbf","description":"This example shows the BearNBearToken smart contract, an ERC-721 non-fungible token implementation that manages a collection of 17,153 digital artworks. The Solidity code defines core NFT functionality including token ownership tracking, metadata storage for names and descriptions, and a tiered pricing system for minting, burning, and modifying token attributes. It uses OpenZeppelin’s SafeMath, Address, EnumerableSet, and EnumerableMap libraries to handle arithmetic operations and efficient owner-token lookups. The contract also incorporates a reward pool mechanism that distributes burn rewards across token holders, with provenance recorded via an IPFS hash.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-565d71987d2e83d17e094c9611c50bbf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
