Zodiac: The expansion pack for DAOs

A composable design philosophy for DAOs, Zodiac is a collection of tools built according to an open standard.

The Zodiac collection of tools can be accessed through the Zodiac App available on Gnosis Safe, as well as through the repositories below. If you have any questions about Zodiac, join the Gnosis Guild Discord.

This repository links to technical tutorials on how to configure each using the CLI.

Zodiac enables:

• Flexible, module-based control of programmable accounts
• Un-opinionated standards for programmable account interaction
• Reusable implementations of core and factory logic

The Zodiac open standard consists of Avatars, Modules, Modifiers, and Guards architecture:

1. Avatars are programmable Ethereum accounts, like the Gnosis Safe. Avatars are the address that holds balances, owns systems, executes transaction, is referenced externally, and ultimately represents your DAO. Avatars must expose an interface like IAvatar.sol.

2. Modules are contracts enabled by an Avatar that implement some decision making logic. They should import Module.sol.

3. Modifiers are contracts that sit between Modules and Avatars to modify the Module's behavior. For example, they might enforce a delay on all functions a Module attempts to execute. Modifiers should import Modifier.sol and must expose an interface like IAvatar.sol

4. Guards are contracts that can be enabled on Modules and implement pre- or post-checks on each transaction that the Module executes. This allows Avatars to do things like limit the scope of addresses and functions that a module can call or ensure a certain state is never changed by a module. Guards should import BaseGuard.sol.

Overview

Installation

yarn add @gnosis.pm/zodiac

Usage

Once installed, you can use the contracts in the library by importing them to your contract:

pragma solidity ^0.8.6;

import "@gnosis.pm/zodiac/contracts/core/Module.sol";

contract MyModule is Module {
  /// insert your code here
}

Zodiac compliant tools

Avatars

• Gnosis Safe: The most trusted platform for managing digital assets on Ethereum. Zodiac embraces Gnosis Safe as a powerful, extensible and programmable account standard. Gnosis Safe is the reference implementation of the IAvatar.sol interface specified in this library. However, all Zodiac tools are framework agnostic, and they can be plugged into any programmable account that implements the IAvatar interface.

Modules

• Bridge (developed by Gnosis Guild): This module allows an address on one chain to control an avatar on another chain using an Arbitrary Message Bridge (AMB). This enables a DAO on one chain to control assets and interact with systems like a Gnosis Safe on a different chain.
• Exit (developed by Gnosis Guild): This module allows users to redeem a designated token for a relative share of an avatar's assets, similar to MolochDAO's infamous rageQuit() function.
• Governor (Developed by Gnosis Guild): An opinionated implementation of OpenZeppelin's Governor contracts designed to be used in a Zodiac-style setup, allowing a Avatar (like a Gnosis Safe) to controlled by on-chain governance similar to Compound's Governor Alpha and Bravo.
• Optimistic Governor (developed by Outcome Finance: This module allows on-chain executions based on Snapshot proposal results. The module utilizes UMA's optimistic oracle to govern a Gnosis Safe based on a set of rules defined off-chain.
• Reality (developed by Gnosis Guild): This module allows on-chain execution based on the outcome of events reported by Reality.eth. While built initially to execute Gnosis Safe transactions according to Snapshot proposals, this module is framework agnostic. It can enable proposal execution from just about anywhere. For example, it can bring Discord polls on-chain.
• Safe Minion (developed by DAOHaus): This module allows Moloch DAOs to manage the assets in a Gnosis Safe based on the outcome of v2 Moloch DAO proposals. Safe Minion enables Moloch DAOs to manage collections of NFTs, manage LP positions with AMMs, and initiate any other arbitrary interactions. It enables DAOs that start as a Gnosis Safe to later delegate governance to a Moloch DAO.
• Tellor (developed by Tellor): This module allows on-chain executions based on Snapshot proposal results, it uses the Tellor oracle to retrieve the data in a secure and decentralized manner.
• Usul (developed by SekerDAO): This module allows avatars to operate with trustless tokenized DeGov, similar to Compound or Gitcoin, with a time-boxed proposal core that can register swappable voting contracts. This enables DAOs to choose from various on-chain voting methods that best suit their needs.

Modifiers

• Delay (developed by Gnosis Guild): This modifier allows avatars to enforce a time delay between when a module initiates a transaction and when it will be executed by an avatar.
• Roles (developed by Gnosis Guild): This modifier allows for fine-grained, role-based, access control for enabled modules. Scopes for a given role include allowed addresses, and optionally include allowed functions on allowed addresses, allowed parameters on allowed functions, whether or not delegate calls are allowed to an allowed address, and whether or not value (ETH) can be sent to an allowed address.

Guards

• Meta (developed by Cardstack): This guard allows an avatar to have multiple checking processes by registering multiple guards to this meta guard.
• Scope (developed by Gnosis Guild): This guard allows an avatar to limit the scope of the addressable functions with which its owners can interact. This enables the avatar to define granular permissions for different control mechanisms.
