The Governor Contract, or DssGov for short, is a Dai Stablecoin System Contract that authorises Maker governance to make changes to the Maker protocol by supporting on-chain proposals.

This repository contains three main contracts:

• DssGov: actual governance contract

• GovExec: contract which acts as a delayer between proposals being approved and getting them executed.

• GovMom: contract that has authority to drop proposals in DssGov. It will be used together with a GovExec with 0 time delay.
