NFT Project

NFT通过一个TokenId对应一个URI来确保资产的唯一性 TokenId和playerAddress是一对一的关系

ERC721合约交易

初始化合约时，会触发一次Transfer事件，会把最新的tokenId 和 player emit出来，后台及时监控到这个事件把内容存入数据库 contract.on('Transfer', (_, playerAddress, tokenId: BigNumber) => { console.log(playerAddress, tokenId.toNumber(), 'transfer') })

这个URI保存的地址的内容会变怎么办？

用ipfs保证资源不可变

比如URI：

其对应的图片内容如下

由此，我们用HeroFactory可以做个自己的NFT
