nft-standards
Implement NFT standards (ERC-721, ERC-1155) with proper metadata handling, minting strategies, and marketplace integration. Use when creating NFT contracts, building NFT marketplaces, or implementing digital asset systems.
价格
免费
- 安装：免费
在组织开通时一次性收取；再次读取清单或下载不重复收费。
以上为公开标价。你的组织可能有协议价，以控制台显示的价格为准。
如何使用
为组织安装
开通即安装：组织固定使用开通时的版本（当前为 1.0.0）。升级到新版本需要取消后重新开通。
创建凭证
客户端使用组织凭证读取；绑定到数字人后，数字人使用绑定凭证按需加载。请求中携带：
Authorization: Bearer $ZGI_MARKET_KEY读取清单与安装包
清单列出版本、文件和校验值；安装包是一个 zip 文件。
读取清单 curl "https://market-api.zgi.im/v1/market/skills/nft-standards/manifest" \ -H "Authorization: Bearer $ZGI_MARKET_KEY"下载安装包 curl "https://market-api.zgi.im/v1/market/skills/nft-standards/package" \ -H "Authorization: Bearer $ZGI_MARKET_KEY" \ -o nft-standards.zip读取清单和下载安装包不计入用量。下载后请用响应头中的 SHA-256 校验文件。

# NFT Standards
Master ERC-721 and ERC-1155 NFT standards, metadata best practices, and advanced NFT features.
## When to Use This Skill
- Creating NFT collections (art, gaming, collectibles)
- Implementing marketplace functionality
- Building on-chain or off-chain metadata
- Creating soulbound tokens (non-transferable)
- Implementing royalties and revenue sharing
- Developing dynamic/evolving NFTs
