# Autopool ETH Contracts Overview At its simplest, this contract system is a set of a sub-systems that all revolve around, and reference each other through, a system registry. There are only a handful of user interactions that are mostly surfaced through a multicall router. Additionally, we have a few permissioned keeper-like processes that handle other parts of the system. Here we’ll run through general functionality and then dive deeper into each contract/system --- # 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.
