Master Edition Plugin

The Master Edition Plugin is a Authority Managed plugin that is used with Core Collections to group Editions, provide provenance and store the maximum edition supply. Together with the Edition Plugin those Editions could be compared to the Edition concept in Metaplex Token Metadata.

The Master Edition Plugin will work in areas such as:

  • Grouping Editions
  • Providing Procenance

Intended Useage

We recommend to

  • Group the Editions using the Master Edition Plugin
  • use Candy Machine with the Edition Guard to handled numbering automatically.

Works With

MPL Core Asset
MPL Core Collection
