Ubiquity Dollar

Introducing the flagship product of Ubiquity DAO. The Ubiquity Dollar (uAD) is a collateralized stablecoin.

• The deployed smart contracts can be found in the docs.
• The source code for those are archived here.

Contributing

• We welcome everybody to participate in improving the codebase.
• We offer financial incentives for solved issues.
• Please learn how to contribute via the DevPool here.

Installation

• We use Foundry.
• Here are their docs.
• Please follow their installation guide for your OS before proceeding.

Development Setup

#!/bin/bash

git clone https://github.com/ubiquity/ubiquity-dollar.git
cd ubiquity-dollar/
yarn
yarn build:all # builds the smart contracts and user interface
yarn start & # starts the user interface and daemonize'd to continue to run tests in the background
yarn test:all

Running workspace specific commands

Utilizing yarn workspaces, you can invoke scripts for each workspace individually.

# SCRIPT_NAME=XXX

yarn workspace @ubiquity/contracts $SCRIPT_NAME
yarn workspace @ubiquity/dapp $SCRIPT_NAME

# For example...

yarn workspace @ubiquity/contracts build # Build smart contracts
yarn workspace @ubiquity/contracts test # Run the smart contract unit tests

yarn workspace @ubiquity/dapp build # Build the user interface
yarn workspace @ubiquity/dapp start # Run the application at http://localhost:3000

Committing Code

1. We automatically enforce the conventional commits format for commit messages.

The Conventional Commits specification is a lightweight convention on top of commit messages. It provides an easy set of rules for creating an explicit commit history; which makes it easier to write automated tools on top of.

2. We use prettier, eslint and cspell on staged files in order to enforce a uniform code style. Please do not circumvent these rules.

Network Settings

Network	Chain ID	RPC Endpoint	Comment

anvil	31337	http://127.0.0.1:8545	Used for local development

Deploying Contracts (Ubiquity Dollar Core)

In two separate terminals run the following commands:

yarn workspace @ubiquity/contracts start:anvil # starts the anvil testnet

yarn workspace @ubiquity/contracts deploy:development # deploys the contracts to the anvil testnet

You need to create .env file inside the contracts folder with PRIVATE_KEY, PUBLIC_KEY, MNEMONIC, and CURVE_WHALE all filled. PRIVATE_KEY will be used to deploy locally and the matching PUBLIC_KEY will be the admin on all the smart contracts. MNEMONIC is used when launching Anvil and will ensure your PUBLIC_KEY account is funded.

The .env.example is pre-populated with the recommend test MNEMONIC, test PRIVATE_KEY, and test PUBLIC_KEY.

If successful it will show a readout of accounts generated from MNEMONIC and the port it's listening on.

This will first impersonate the CURVE_WHALE and transfer some tokens so we can create a UbiquityDollar/3CRV pool, and then it will deploy the Ubiquity Dollar core protocol via a series of Solidity scripts via Forge.
