Assets Management

Fetching Assets

Assets are items on Horizon Network. They are represented by the Asset type, defined in TypeScript:

/**
 * Simple NFT asset spec
 */
export interface Asset {
  // Information about the collection to which this asset belongs
  collection: collectionSchema,
  // Name of this asset
  name: string,
  // The asset's token ID
  token_id: string,
  // The asset's contract address
  token_address: string,
  // Address of the user who owns this asset
  owner: string,
  // Description of this asset
  description?: string,
  ...
}

The Asset is the minimal type you need for most marketplace actions. The following call will retrieve all Assets from a specific assetContract:

const opts = {
  'assetContract': "0x88Ef499ab1688DE727c21f1b72fAaEe1A3F455AD"
}
const asset: Assets = await client.getAssets(opts)

Fetching Asset Detail

The following call will retrieve an Asset from a specific tokenId and assetContract:

const asset: Assets = await client.getAsset(assetContract, tokenId)
