实操讲解：如何创建自己的ERC721非同质化资产生物商店？

2.6 资产形象优化

这个店铺资产的图形是采用默认的海洋生物图标，并不是辉哥期望的野狼队标识。 这个需要配置每个资产的MetaData元素。 例如在浏览器输入1# ERC721资产的URI： https://rinkeby-api.opensea.io/api/v1/asset/0x5c1188ac19ce51cd5d2dcd10ff5c749417da42d1/1/ 可以返回由OpenSea配置的ERC721资产特性信息。 辉哥会在下一篇文章详细介绍如何修改ERC721的MetaDATA，让它们跟野狼队的标识LOGO更加匹配。
