Cargo Metadata

Cargo has a unique metadata structure to support audio, video, and 3D files.

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
