Broker

The Broker is responsible for orchestrating swaps in the Mento protocol. It does that by fulfilling three main responsibilities:

• Discoverability: It maintains a list of all exchange providers registered in the system.

• Treasury management: It has spending rights on the Mento Reserve and can mint and burn any stable asset in the system, thus it is responsible for moving around assets during a trade.

• Safety: In service of stability, it enforces trading limits in the protocol, constraining the volume of assets that can be traded over time.

While it is responsible for moving around assets during a swap, it doesn't know how to price swaps. For that, it relies on exchange providers. These abstract components implement a unified interface and can be plugged into the Broker to provide exchanges between two or more assets. The first exchange provider implemented is the BiPoolManager.
