💰 TrueFi Smart Contracts

Coverage Status

🗂 Table of Contents

💡 Intro

TrueFi is a decentralized protocol for uncollateralized lending. This repository contains all smart contracts used across TrueFi ecosystem. Contracts are written in Solidity. All key functionalities are tested with attached TypeScript test suite. Apart from contracts and tests repository contains scripts used for deployment and maintenance of existing infrastructure.

📎 Projects

Repository consists of following sub-projects.

TrueFi

Core TrueFi smart contracts. These contracts are responsible for establishing main protocol functionalities like creating loans, rating loans, rewarding raters etc. This repository also contains contracts used for TRU liquidity mining program.

True Currencies

Contracts used for True Currencies - a set of fully-backed stablecoins. True Currencies feature tokens pegged to USD, AUD, HKD, GBP and CAD.

Governance

Contracts implementing TrueFi governance. Sub-project features both governor contract and all contracts implementing voting mechanisms.

Proxy

Contracts and utilities allowing to use unified proxy structure across whole TrueFi ecosystem.

Trust Token

Contracts implementing TRU - TrueFi ecosystem governance token.

True Gold

Smart contracts implementing True Gold - a synthetic gold on Ethereum blockchain.

🧰 Installation

In order to compile the contracts first clone the repository. In order to do that run

git clone git@github.com:trusttoken/smart-contracts.git

Then enter smart-contracts directory and install all necessary dependencies by running

yarn

Important note: You need to have node and yarn already installed on your machine.

In order to compile the smart contracts run

yarn build

Testing

In order to run test suite, run

yarn test

Make sure to install all dependencies and compile contracts first.

In order to run linter, run

yarn lint

In order to run typescript type checks, run

yarn typecheck

All three check suites can be run at once by running

yarn checks

🛡 Coverage

Before proceeding make sure you have the smart contracts compiled. If needed compile by running

yarn build

In order to run coverage, run

yarn coverage

You may also want to run coverage for specific tests. You can do so by providing named argument --testfiles

yarn coverage --testfiles "path/to/tests"

Important note: Keep in mind that when running coverage smart contracts are additionally compiled with optimizer disabled and it may take longer for tests to complete.
