Abax Governance Smart Contracts

This repository contains the source code of Abax Governance smart contracts as well as a set of comprehensive test suites.

Project structure

• src - contains the source code of Abax Governance's contracts
• tests - contains e2e tests as well as utilities used for writing/running tests
• scripts - contains helpful scripts

Contracts

Overview

The repository's src/contracts folder contains the following contracts:

• abax_token - ABAX Token implementation compliant with PSP22 standard
• abax_treasury - Treasury contract that manages the treasury of the DAO
• abax_tge - Token Generation Event contract that manages the token generation event
• governor - Governor contract that manages the governance of the DAO, implements the voting mechanisms & manages ABAX token staking. It implements PSP22 standard & PSP22Vault trait for staking

The pendzl library was used to develop smart contracts - a library that provides implementations for PSP22, AccessControl, SetCodeHash and more used commonly in Abax projects. It is available at https://github.com/pendzl/Pendzl.

File structure

Each contract follows a pattern with lib.rs file containing the smart contract definition/its entry point and modules folder containing the implementation of the contract's functionality as well as traits & storage definitions. In all contracts AccessControl was used to manage the roles and permissions of the contracts. Each contains a detailed inline documentation with a detailed description of the contract and its functionality.

The folder test_purpose contains contracts that were used for testing purposes only and are not part of the final implementation.

Contracts build and deployment

Prerequisites

• To build Abax Governance smart contracts without docker you need to have a prepared rust environment, with cargo-contract compatible with ink! 5.x . Follow official guides on how to set up/migrate to an environment that supports ink! 5.x:

• https://use.ink/faq/migrating-from-ink-3-to-4/#compatibility

• https://use.ink/faq/migrating-from-ink-4-to-5#how-to-upgrade

• https://use.ink/getting-started/setup

• To run tests and use convenience scripts you have to run the pnpm/pnpm install (or an adequate command for your npm package manager) command to install the required npm packages.

Build

Run pnpm build:debug (for debug build) or pnpm build:release (for release build) to build the contracts. Note: If you do not have docker installed change verifiable to false in typechain.config.json. Otherwise the build will fail.

Tests

To run tests, execute the following command:

pnpm test

This will spin up a local node in background and run the tests. The test log will be be stored to substrate-contracts-node.testrun.log file.

Audits

The code was audited by Kudelski Security in June 2024. The audit is publicly available here
