# The Problem

Extracting yield across multiple DeFi protocols carries a number of risks. Notably: 

* Smart-contract
* Dynamic APYs
* Bridging between chains
* Sourcing new investment opportunities
* Modelling impermanent loss
* Optimizing returns and providing derivative overlays to minimize drawdowns

Moreover, searching for yield in the current crypto market can be a tough and daunting task.
