Cargo Metadata

Cargo extends the ERC-721 metadata shape to be able to support audio, video, and 3D files. If you would like to display Cargo's metadata on your platform, or if you'd like to create a collectible on another platform and would like Cargo to support audio, video, or 3D please use the following metadata structure:

Supported file types

Audio - MP3

Video - MP4, WEBM

3D - GLB, GLTF files + Associated files

Cargo Metadata Structure

// TypeScript type
type Metadata = {
    // Standard ERC-721 fields
    name: string;
    image: string;
    description: string;
    
    // Cargo specific fields
    cargoDisplayContent: {
        type: "3D" | "audio" | "video";
        // Array of files
        // 3D files can have multiple files. There will be one .gltf file which
        // may have associated files.
        files: string[];
    }
}
