SIMPLE MULTI SIG WITH ROLES

This branch is based on https://github.com/scaffold-eth/scaffold-eth/tree/meta-multi-sig.
You should check it out first. When you do, you'll see that there's a proposed challenge: Add roles to the multi-sig-wallet. This is a possible solution.

GOALS

This is a very simple example. There are only two roles: OG and DEFAULT. The code is commented wherever relevant changes were written, but the intended mode of functioning was this:

• On contract initialization, grant every initial owner the OG_ROLE. Also, give the contract the DEFAULT_ADMIN_ROLE so it can grant/revoke roles.
  
• Every single transaction, in addition to having the required number of signatures, must have at least one OG as a signer.
  

How to run:

• After you download, you might need to run yarn install in the project folder;
• After that open 4 consoles in the project folder and run:
  1. yarn start
  2. yarn chain
  3. yarn backend
  4. yarn deploy

DISCLAIMER: Do your own research. I'm in no way a solidity expert and this code may be faulty!
