📖Smart Contract Functionality

1. Minting NFTs:

   • Users can mint Vault Key NFTs by sending a minimum amount of Ether to the smart contract.

   • Minting is limited to 2 NFTs per wallet to ensure fair distribution.

2. Diamond Vault Keys:

   • There are 10 legendary Diamond Vault Keys (1-10) with unique designs.

   • Diamond Vault Key holders are airdropped FREE raffle tickets for as long as they own the NFT.

   • The remaining 2490 NFTs are common Vault Keys.

3. Burning Mechanism:

   • Key holders can voluntarily burn their Vault Key NFTs.

   • Burning contributes to scarcity, potentially increasing the value of remaining keys.

4. Reward Distribution:

   • Rewards are distributed at specific milestones: 25%, 50%, 75%, and 100% of NFTs minted.

   • Rewards are randomly given to key holders, encouraging participation.

5. Common and Diamond CID:

   • The smart contract provides links (CID) to the images for common and Diamond Vault Keys.

   • We have the option to change the image in a later event if voted upon. (Custom Keys)

6. Last Sale Timestamp:

   • The smart contract records the timestamp of the last sale, providing transparency.

7. Smart Contract Upgradability:

   • The smart contract is built to be upgradeable for potential future improvements.

8. BaseURI and TokenURI:

   • Supports dynamic generation of token URIs based on the token ID and base URI.

9. Automatic Reward Selection:

   • Randomly selects a key holder to receive rewards at specified milestones.

10. Timestamped Airdrops:

    • Initiates three airdrops to every holder at the end of minting based on timestamps.
