Happy Animals turns collecting NFTs into real-world impact for endangered species. Each animal-themed NFT on various blockchains sell allocates a fixed portion of primary sales and royalties to a transparent conservation treasury. Every two weeks all current holders are automatically entered into an on-chain lottery whose prizes grow with marketplace volume. Winners earn ETH while partner NGOs receive matched donations, both verifiable on-chain. A rarity system, seasonal drops, and quests keep the community engaged, while our open data dashboard shows exactly how much has been routed to wildlife projects. Collect, earn, and protect—one Happy Animal at a time.
