There are two ways to create a collection:

  1. Using Asset IDs - If you have already created atomic assets or want more control on each atomic asset in the collection, you can use this method.
  2. Using Asset Files - This method is used to create a collection from a set of files. The Assets will share the same traits such as License, Description but will vary in suffixes. eg - Asset #0, Asset #1, Asset #2 etc.

​
Using Asset IDs

​
Basic Syntax

The function is called as follows:

const tx = await toolkit.collection.createCollectionWithAssetIds(opts);

​
Input Parameters

The function takes one input parameter - opts: CreateTradableAssetOpts. It contains the following parameters

  • assetIds: string[]: An array of asset IDs to be grouped in the collection.
  • collection: CollectionSpecificTags: The collection specific tags as per Collection Data Protocol. It contain feilds such as name, collectionType, thumbnail, banner and collectionCode. For details on the options see the Collection Specific Tags section.
  • discoverability: DiscoverabilityTags: The discoverability tags for the Collection as per ANS-110 Specification. Contains feilds like title, description, type and topics. For details on the options see the Discoverability Tags section.

type should be equal to Document as per the Collection Data Protocol

  • stamp (optional): StampableType: The stamping options for the collection. If stamp is specified the your collection can be stamped by others. Defaults to false. For details on the options see the Stamping Options section.
  • additionalTags (optional): Tag[]: Additional tags for the Atomic Asset. Duplicate tags will throw an error. For details on the options see the Tag section.

For details on the options see the Create Collection Options section.

​
Return Value

The function returns a promise that resolves to UploadResponse, Transaction, or TurboUploadDataItemResponse depending on whether Irys or Turbo are used or not.

  • UploadResponse - Returned when Irys is used. It contains fields such as:
    • id: string - The transaction ID of the collection.
    • signature: string - The signature used while creating the collection.
    • timestamp: number - The timestamp of the transaction.
  • Transaction - Returned when Arweave is used. It contains fields such as:
    • id: string - The transaction ID of the collection.
    • owner: string - The owner of the collection.
    • tags: Tag[] - The tags of the collection.
    • data: Uint8Array - The data of the collection.
    • signature: string - The signature used while creating the collection.
  • TurboUploadDataItemResponse - Returned when Turbo is used. It contains fields such as:
    • id: string - The transaction ID of the collection,
    • timestamp: number - The timestamp of the transaction,
    • winc: string - The amount of Turbo Credits, in Winston Credits, spent on the upload,
    • version: string - The version number of the upload receipt returned,
    • deadlineHeight: number - The latest block height in which the uploaded data will be settled on Arweave,
    • dataCaches: array - A list of nodes where the data was cached while upload to Arweave is pending,
    • fastFinalityIndexes: array - A list of nodes where data is made available while waiting for it to settle on Arweave,
    • public: string - The public key of the wallet used for upload,
    • signature: string - The signature used while creating the collection,
    • owner: string - The owner of the collection.

Example Usage

const tx = await toolkit.collection.createCollectionWithAssetIds({
    assetIds: [

        'wP6jOlDS3xxRLaeJSiSsjVVYGFFQBkvwZFNLvicj7YY',
        'H4Jvfg0iPmzCKfoIariAqNScWPRIvDvXJ01zYiwWKBI',

        type: 'Document',
        title: 'Collection Name',
        description: 'Collection description',
        topics: ['topic1', 'topic2'],
    },
    collection: {
        name: 'Collection Name',

    },
    stamp: {
        isStampable: true,
        collectionName: 'Collection Name',
        owner: 'Z7t5Dw42qalSx9-1u4wINXWayX7Ktu_i3sbc31tSDb4',
        ticker: 'ATOMIC',
    },
});

​
Using Asset Files

​
Basic Syntax

The function is called as follows:

const tx = await toolkit.collection.createCollection(callback, opts);

​
Input Parameters

The function takes two input parameters:

  • callback: (progress: CollectionProgress, error?: string) => void: The callback function to be called for progress, CollectionProgress has two parameters:

    • step: string: The current step of the transaction.
    • progress: number: The progress of the transaction out of 100.

  • opts: CreateCollectionOpts: It contains the following parameters:

    • assets: File[] | string: An array of files or the path to the directory containing the files to be grouped in the collection.
    • thumbnail: File | string: The thumbnail file or the path to the thumbnail file for the collection.
    • banner: File | string: The banner file or the path to the banner file for the collection.
    • license (optional): LicenseTags: Universal Data License Tags for the Asset. By default base UDL tags will be used. For details on the options see the License Tags section.

const onCallback = (progress) => {
    console.log(progress);
