Prior to collection registration, you need to register your project.
A collection refers to a deployed smart contract. All minted assets belong to a collection, and in order to mint assets on L2 you must first register your collection (smart contract) with Immutable X.
Each collection belongs to a project, and all projects are limited to creating five collections within a four-week period. Learn more.
Collection limits can be increased by contacting support about your project. Be sure to include your reason for an increase. Our team will respond to your request within 2 business days."
Create a collection
A collection contains the following fields:
|Field||Required (Default value)||Value Type / Notes|
|yes||Make sure this matches the owner of the smart contract specified in |
|yes||See notes here|
|no||Do not put an empty text or a non-url for this as it will result to a broken icon link in Marketplace.|
|no||Used for display purposes.|
Our repository imx-examples provides easy to use open source examples. Follow the instructions in the README to get started.
Update an existing collection
|Field||Value Type / Notes|
|Do not put an empty text or a non-url for this as it will result to a broken icon link in Marketplace.|
|Used for display purposes.|
contract_address is a field that should not be changed. If
metadata_api_url is modified AFTER minting, the existing assets that used the previous
metadata_api_url will not be modified. The new
metadata_api_url will be used for new mints.
