// StakedNFTMetadata Interface:
// This interface defines a blueprint for the NFT Stake contract. Its purpose is to enable the creation of
// the minting contract independently from the stake contract, allowing developers to work on the stake
// contract's logic without deploying it simultaneously.
//
// The stake contract must implement this interface for proper integration with the minting contract,
// which works with newly staked NFTs. The getMetadata method is called by the minting contract's tokenURI
// method after stakeSupplyStart varible is reached (10k) tokens have been minted.
//
// By following this interface, the stake contract is responsible for managing the metadata for staked NFTs,
// ensuring that the stake contract is in control of the metadata and its associated logic.

 * @title  OperatorFilterer
 * @notice Abstract contract whose constructor automatically registers and optionally subscribes to or copies another
 *         registrant's entries in the OperatorFilterRegistry.
 * @dev    This smart contract is meant to be inherited by token contracts so they can use the following:
 *         - `onlyAllowedOperator` modifier for `transferFrom` and `safeTransferFrom` methods.
 *         - `onlyAllowedOperatorApproval` modifier for `approve` and `setApprovalForAll` methods.
 *         Please note that if your token contract does not provide an owner with EIP-173, it must provide
 *         administration methods on the contract itself to interact with the registry otherwise the subscription
 *         will be locked to the options set during construction.
