🧾 Kii Solidity Contracts

This repository contains smart contracts for the KiiChain ecosystem, written in Solidity.

📘 Introduction

This is a simple swap contract that uses the Cosmos bank module on the Kii EVM testnet. This contract is designed to swap EVM Kii tokens for internal Cosmos Kii tokens and vice versa.

🚀 Getting Started

Follow these steps to set up the development environment and test the contracts locally.

1. Clone the Repository

git clone https://github.com/KiiChain/kii-solidity-contracts
cd kii-solidity-contracts

2. Install Dependencies

npm install

⚠️ Make sure you are using Node.js v18 or higher Check your version with:

node -v

3. Compile the Contracts

npx hardhat compile

4. Run the Tests

npx hardhat test

✅ Notes

1. Added basic test: test/basic-test.ts for AirdropNFT
2. Removed default Hardhat boilerplate: test/Lock.ts

📂 Project Structure

/contracts             → Solidity smart contracts
/test                  → Test files using Hardhat framework
/hardhat.config.ts     → Hardhat configuration (TypeScript)
/scripts               → Deployment and utility scripts (optional)
/README.md             → Project documentation

🧪 Sample Test

1. You can find a basic test file in test/basic-test.ts.
2. This test verifies successful deployment of the AirdropNFT contract.

⚙️ Continuous Integration

This project uses GitHub Actions to run a series of checks on every push and pull request to the main branch. This ensures that the codebase remains consistent and that all tests pass.

The CI workflow runs the following checks:

• Linting: npx solhint 'contracts/**/*.sol'
• Formatting: npx prettier --check 'contracts/**/*.sol'
• Tests: npx hardhat test

You can run these checks locally to ensure your contributions will pass the CI.
