Subscription

Subscription is a unique feature. This feature allows NFT owners to store multiple URIs(in other words: "assets") and update their NFT metadata over time, making NFTs more dynamic and adaptable to market changes.

If you would like to learn more about Subscription feature please check our Glossary here.

Here are the functions that you can use to subscribe to an entity in mQuarkSubscriber contract;

 * @param _tokenId The ID of the token being subscribed to
 * @param _tokenContract The address of the token contract
 * @param _subscriptionId The ID of the subscription being purchased
 * @param _directUpdateEnabled Boolean indicating if direct update is enabled
 */
function subscribeToEntity(
    uint256 _tokenId,
    address _tokenContract,
    uint256 _subscriptionId,
    bool _directUpdateEnabled
  ) external payable;

• Subscribe to multiple Entities

/** 
 * See subscribeToEntity

function subscribeToEntities(
    uint256 _tokenId,
    address _tokenContract,
