# Executive Summary: The Prime Brokerage Protocol of DeFi IPOR Fusion is **institutional grade vault infrastructure**, a modular, onchain prime brokerage protocol designed for regulated asset managers and institutional allocators. It provides an entire suite of vault technology and tools for managing digital asset strategies with institutional discipline, enabling segregated mandates, programmable risk controls, and transparent exposure verification. Unlike monolithic vault systems, Fusion utilizes a **mandate-adaptive architecture** that separates the **immutable non-custodial layer** from the configurable strategy layer. This allows institutions to extend their investment capabilities by adding markets or adjusting risk parameters without the operational risk of vault redeployment or opaque core contract upgrades. --- # 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.
