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 This documentation is published with GitBook.
