3. Register a collection

A collection refers to a deployed token smart contract, the tokens of which can be freely transacted (ie. minted, traded, bought and sold) on Immutable X's layer 2.

Each collection belongs to a project.

The best way to create a project is to use the imx-examples repository.


  1. Register a collection
  2. Update a collection

Fields that cannot be updated:

  • metadata_api_url - if this field is modified AFTER minting, existing assets using the previous URL will not be modified, however, the new URL will be used for new mints.
