HIPPO (also known as Sudeng) is a meme coin built on the Sui blockchain, inspired by Moo Deng, a baby hippo born in Thailand's Khao Yai Open Zoo. The project combines the viral appeal of meme culture with community-driven initiatives to promote wildlife conservation.

Since Moo Deng’s birth on July 10, 2024, her adorable presence has gained global attention. The HIPPO project partnered with the zoo where she resides, donating 5 million Thai Baht (approximately $150,000 USD) to support wildlife conservation efforts.

As of November 2024, HIPPO's market capitalization has exceeded $290 million, marking a historic milestone. The project's success not only highlights the potential of meme coins but also demonstrates the positive role cryptocurrency can play in philanthropy and community-building.
