CommunityContract

This repository contains the Community Contract, a smart contract that manages roles and permissions within a community.

The list of basic features:

• The owner can create roles and manage roles and permissions for other roles.
• When a role is granted to a user, the user obtains an NFT for each role.
• Supports the protocol of Native Meta Transactions (ERC-2771).
• Supports the ownable interface from the OpenZeppelin library, accessible to any user in the "owners" role.
• Uses the standard for representing ownership of non-fungible tokens (ERC-721) with small changes:
• • Every person who has a role also has an NFT that represents belonging to this role. Such an NFT cannot be transferred or burnt. However, when an admin revokes a role from the user, the NFT also disappears.

Overview

There are 6 predefined roles:

role name| role index --|-- owners|1 admins|2 members|3 alumni|4 visitors|5

The owners role is a single role that can manage itself, meaning one owner can add or remove other owners.

The contract can be used as external storage for getting a list of members.

Any user obtains an NFT with tokenID = (roleid << 160) + walletaddress.
Anyone who can manage a certain role can set up the tokenURI for this role by calling setRoleURI.

Full methods for each contract can be found here: Community. The most usable methods will be described below:
