🐱🌙 The Sailor Guardians saw what happened to $LUNA in May and decided to team up and save the world by sending Luna, the cat, to the moon!
Luna Cat is developed in the direction focusing on NFTs, staking rewards and comical anime stories to give Saylor Moon fans an experience of the journey to the moon with the moon cat Luna.
Mint your NFT and deposit it into the staking pool whilst your staking APY will depend on the rarity of the NFT you hold. There will only be 1,000 NFTs available to be minted!
