FlipThisMetadata FlipThisMetadata is a lightweight, browser-based tool designed to generate compliant JSON metadata for Chia Network NFTs.
It streamlines the creation of metadata files by providing a user-friendly interface for inputting data, automatically formatting it to CHIP-0007 standards, and optionally extending it with CHIP-0015 off-chain data fields.
🚀 Features Standard Compliance: formatting for CHIP-0007 (NFT Metadata) and CHIP-0015 (Off-chain Data).
Zero Dependencies: Built with vanilla JavaScript and Tailwind CSS (via CDN). No npm install or build steps required.
Local SHA256 Hashing: Includes a Drag-and-Drop tool to calculate file hashes directly in the browser. Your files never leave your computer.
Collection Management: Built-in UUID v4 generator for Collection IDs.
Dynamic Attributes: Easily add, remove, and manage trait attributes and collection attributes.
Live Preview: Real-time JSON syntax highlighting as you type.
Smart Auto-fill: Automatically detects encoding formats based on selected file types (e.g., selecting DigitalDocument sets format to application/pdf).
🛠 Standards Supported CHIP-0007: The core standard for defining NFT names, descriptions, attributes (traits), and collection information.
CHIP-0015: An extension for linking rich off-chain data (PDFs, Videos, 3D Models) with hash verification (sha256), encoding formats, and creator attribution.
📦 Installation & Usage Since this is a client-side tool, there is no backend to configure.
Option 1: Run Locally (Recommended) Clone the repository:
Bash
git clone https://github.com/your-username/flip-this-metadata.git Navigate to the folder:
Bash
cd flip-this-metadata Open index.html in any modern web browser.
Option 2: Hosted Because this is a static file, you can host it immediately using GitHub Pages, Vercel, or Netlify by simply pointing them to this repository.
📖 How to Use
-
Core Info Fill in the basic details of your NFT (Name, Description, Minting Tool).
-
Attributes Click "Add Top-Level Attribute" to define traits (e.g., Background: Blue, Rarity: Legendary).
-
Collection Data Enter your Collection Name.
Click Generate UUID to create a unique Collection ID (v4 Standard).
Add specific collection attributes if necessary.
- CHIP-0015 Data (Optional) Toggle "Enable CHIP-0015 Data Fields" to access advanced options:
SHA256 Tool: Drag your asset (image, PDF, video) onto the drop zone. The tool will calculate the hash and automatically fill the sha256 field for you.
Creator Info: Add attribution for the organization or person behind the NFT.
Thumbnails: Define separate thumbnail assets with their own hashes and URLs.
- Export Once finished, click Copy to Clipboard to grab the raw JSON, or hit Reset to start over.
🔒 Privacy & Security Client-Side Only: All logic runs inside your browser.
No Data Collection: No data is sent to any external server.
Local Hashing: The SHA256 calculator uses the browser's SubtleCrypto API. Your files are processed in memory and are not uploaded anywhere.
