# Cardano #### ALL STARTED WITH BATTLECATS NFTs > Our debut NFT project, BattleCats, marked the start of our journey on the Cardano blockchain in 2021, making us one of the pioneers in leveraging this technology. We are delighted to have introduced feline characters to the Cardano ecosystem through BattleCats. BattleDogs and BattleApes were released in 2022, as well as the Last Guardian project that we have acquired. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
