What is DAO Treasury used for?

Could you please elaborate on the purpose of a DAO Treasury? I'm curious to understand how it functions within the broader cryptocurrency and finance ecosystem. What are the key roles and responsibilities of a DAO Treasury? How does it manage and allocate funds to support the development and growth of decentralized autonomous organizations? Also, how does it ensure transparency and accountability in its operations? I'm particularly interested in the mechanisms it employs to protect the interests of its stakeholders and maintain the integrity of the DAO. Thank you for your insights.
