Wrapped NFTs

WrappedNftStakingPool

WrappedNftStakingPool is used for wrapped staking when user's stake is wrapped into NFT token. When user stakes tokens, contract mints NFT and wraps stake into it, i.e. NFT token's ownership yeilds into stake owneships. Stake is locked for the fixed period and can be withdrawn together with APR reward. User's can stake until total staking limit is reached.
