Liquid Keys from ApeLiquid.io evolve over time. Liquid keys unlock the Liquid Forge and Forge (or stake) your NFTs and earn METL each month or unlock a Mythic Gateway which will evolve your NFT over time. A Mythic Creature is created by sacrificing a Liquid Legend, Liquid Invader, Azuki Ape Social Club, or Typical Tiger and a Cub, then burning a Liquid Artifact to open the Gateway and begin the Journey.
