Registry
Overview
The Registry is an immutable contract that stores the addresses of important protocol entities. These addresses can only set and modified by protocol governance.
The Registry stores addresses to core protocol modules such as the Risk Engine, Pool, Position Manager, etc. These are stored using their respective registry key hashes which can be used to query them.
The Registry also stores addresses to interest rate models that can be used by Base Pools. When a new Base Pool is initialized, the creator must pass a registry key hash which corresponds to the interest rate model to be used by the new pool.
State Variables
