Welcome to the VeBetterDAO Smart Contracts repository! This open-source repository houses the smart contracts powering the decentralized VeBetterDAO on the VeChain Thor blockchain. Dive into a world of transparent and auditable governance mechanisms, leveraging Solidity, Hardhat, and more to ensure robust decentralized operations.

The complete documentation for the VeBetterDAO and the contracts can be found here.

Our contracts are upgradeable and versioned. See the contracts changelog for more information on the changes introduced in each of new upgraded version.

Audit

The VeBetterDAO smart contracts have undergone a comprehensive audit by Hacken. The audit report (Hacken_Vechain Foundation_[SCA] VeChain _ VeBetter DAO _ May2024_P-2024-304_1_20240621 16_17) can be found in the root of the repo.

Install via NPM

You can install the package via NPM to get the ABIs, contract addresses and interfaces:

yarn add @vechain/vebetterdao-contracts

Requirements

Before contributing or deploying, ensure your environment meets the following specifications:

• Node.js (v20 or later): Download Node.js 📥
• Docker: Install Docker for running isolated contract environments 🐳
• Hardhat: Essential for smart contract compilation and deployment. Start with Hardhat ⛑️

Repository Structure

Contracts (contracts/) 📜

Core smart contracts written in Solidity. Managed with Hardhat, these contracts are ready for deployment on the VeChain Thor blockchain.

Artifacts (artifacts/) 🏺

Automatically generated contract artifacts post-compilation. Contains ABI and contract bytecode.

TypeChain Types (typechain-types/) 📚

TypeScript typings for smart contracts, generated to enhance developer experience by providing strong typing for contract interactions.

Environment Setup ⚙️

Set up your environment to integrate smoothly with the blockchain:

• MNEMONIC: Store the mnemonic for the deploying wallet in a .env file at the root to maintain security and ease of use.

Getting Started 🏁

Clone the repository and install dependencies with ease:

yarn install # Run this at the root level of the project

Compilation and Testing 🛠️

Compile contracts and generate necessary artifacts and types:

yarn compile

Testing on Hardhat Network

yarn test:hardhat

Testing on Thor Solo Network

yarn test:thor-solo

Code coverage

You can generate code coverage reports using the following command:

yarn test:coverage:solidity

A folder named coverage will be created in the root directory with the coverage report. Open index.html in your browser to view the report.

Additionally a report is generated each time a PR is merged on main and can be found here.

Slither

Note that slither does not seem to be working with the repo as-is, resulting in an enum type not found error:

slither.solc_parsing.exceptions.ParsingError: Type not found struct Checkpoints.Trace208
