Zodiac

A library for composable DAO tooling built on top of programmable accounts, like the Gnosis Safe.

Zodiac enables:

• Flexible module based control of programmable accounts.
• Un-opinionated standards for controlling programmable accounts.
• Reusable implementations of core and factory logic.

Zodiac defines four key components:

1. Avatars: 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: Contracts that are enabled by an Avatar and implement some decision making logic. They should import Module.sol.

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

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

Overview

Installation

yarn add https://github.com/gnosis/zodiac

Usage

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

pragma solidity ^0.8.6;

import "https://github.com/gnosis/contracts/core/Module.sol";

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

Zodiac compliant tools

Avatars

• Gnosis Safe: The most trusted multisig solution for the Ethereum ecosystem, but also a powerful and extensible programmable avatar standard. The Gnosis Safe is the reference implementation of the IAvatar.sol interface specified in this library. (Built by Gnosis)

Modules

• Reality: allows on-chain execution based on the outcome of events reported by Reality.eth. Used to build the SafeSnap module for Snapshot. (Built by Gnosis Guild)
• Bridge: allows an address on one chain to control an avatar on another chain, via an arbitrary message bridge. (Built by Gnosis Guild)
• Exit: allows users to redeem a designated token for a relative share of an avatars assets, similar to Moloch's infamous rageQuit() function. (Built by Gnosis Guild)
• Safe Minion: 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. (Built by DAOHaus)
• Seele: allows avatars to operate with trustless DeGov, similar to Compound or Gitcoin, with a time-boxed proposal core that can register swappable voting contracts, allowing DAOs to choose from various on-chain voting methods that best suit their needs. (Built by TokenWalk)

Modifiers

• Delay: allows avatars to enforce a time delay between when a module initiates a transaction and when it will be executed by the avatar. (Built by Gnosis Guild)

Guards.

• Scope: a transaction guard for the Gnosis Safe that restricts the multisig owners to only calling specific addresses and function signatures. (Built by Gnosis Guild)
