How to build a DAO Plugin

Plugin Development Quickstart Guide

Plugins are how we extend the functionality for DAOs. In Aragon OSx, everything a DAO can do is based on Plugin functionality enabled through permissions.

In this Quickstart guide, we will use the Aragon Hardhat template to set up a plugin.

Setting up your environment

We recommend using our hardhat template to get started. If you don't have it installed, you can do so by running:

git clone

Once you have cloned the repository the first step is to add a .env file with your ALCHEMY_API_KEY, there is a .env.example file you can use as a template.

This file contains more env variables that you may need throughout the development process, but to get started you only need to add the ALCHEMY_API_KEY.


## The network used for testing purposes
NETWORK_NAME="sepolia" # ["mainnet", "sepolia", "polygon", "baseMainnet", "arbitrum"]


## One or multiple hex encoded private keys separated by commas `,` replacing the hardhat default accounts.
PRIVATE_KEY="0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80" # Default hardhat account 0 private key. DON'T USE FOR DEPLOYMENTS

## Alchemy RPC endpoint credentials

Once the .env file is created, you can run the following command to install the dependencies:

yarn install && cd packages/contracts && yarn install && yarn build && yarn typechain

Now you are ready to start developing your plugin. You should have two files called MyPlugin.sol and MyPluginSetup.sol inside the contracts folder.

The template is already set up with a basic plugin and plugin setup contract. You can start by modifying these files to create your own plugin. The tests and deployment scripts are also set up for you to use.

Next Steps

This plugin template uses version 1.4.0-alpha.5 of the Aragon OSx protocol. This version is still in development and is not audited yet.
