Teahouse Marge is a hackathon project under Teahouse Finance. It is a revolutionary decentralized margin trading protocol, tailored to operate within THENA's Automated Market Maker (AMM) in the BNB Chain ecosystem. The protocol harnesses unique features of THENA Plugins to introduce novel strategies and mechanisms in the DeFi sector, aiming to significantly enhance liquidity and trading volume. In this article, I will demonstrate how I design the pitchdeck to secure the title for this award-winning project.
