Short Description:
NFTs are speculative and static in nature; once purchased, the value is set by potential buyers. If no one wants to purchase yours, you will lose all of your money. Using your NFT, we want to establish a warranty for your mint, produce value, and let you take out loans. :D
Long Description:
This is a one-of-a-kind NFT collection that uses its NFTs to build an entire DeFi protocol.
After a mint, the entire purchase value goes to the Protocol Treasury and is directly sent to AAVE wMATIC lendingPool. Users can donate their NFTs to the Museum at 90% value at any time (if not used as collateral) this guarantees the value of the NFT to the user.
The Treasury acts as a proxy (no user info is stored in the contract) to interact with AAVE to stake the MATIC and generate value, Wrap/Unwrap MATIC, Check Native Balances, Check aWMATIC Balances and manages all the incoming/outcoming transactions, the functions are:

Mint, stake and earn passive income by using your NFT. On top of that, if you want to hold but use a percentage of your NFT value, take a loan! No more speculative and static NFTs! Our Protocol creates dynamic NFTs used to generate yield and take loans, all while retaining a price warranty at all times!
