Cygnus DeFi Engine

This project showcases the Cygnus DeFi Engine built for the Cygnus Mainnet. It uses Hardhat 3 Beta with mocha and ethers.js for testing and Ethereum interactions.

Project Overview

This example project includes:

• Advanced CNS20 token implementation.
• CNSFactory, CNSPair, CNSRouter, and CNSLibrary contracts.
• Interfaces for ICNS20, ICNSCallee, ICNSFactory, ICNSPair, and IERC20.
• TypeScript integration tests using mocha and ethers.js.
• Ignition modules for deployments.

Usage

Running Tests

To run all the tests in the project, execute the following command:

npx hardhat test

You can also selectively run Solidity or mocha tests:

npx hardhat test solidity
npx hardhat test mocha

Deployment

This project includes example Ignition modules to deploy contracts to the Cygnus Mainnet.

To deploy a module:

npx hardhat ignition deploy ignition/modules/<ModuleName>.ts --network cygnusMainnet

Ensure that your mainnet private key is set in the Hardhat config using the MAINNET_PRIVATE_KEY configuration variable.

Notes

• Users are responsible for compiling the contracts.
• All mainnet interactions should be performed using the cygnusMainnet network configuration in hardhat.config.ts.
• CNS20 and related contracts are fully advanced, supporting factory, pair, router, and library interactions for DeFi applications.
