Hired to enhance a project I previously built during a Hackathon and evolve it into Curfluffles needs. The project consisted of creating “booster packs” of randomized, licensed and limited NFTs from influencers. Used Chainlink VRF to randomly select the rarity and ERC721 NFTs contained in any purchased pack.
