Quick Start Guide

yarn: 3.2.4
node: v18.12.1

*yarn package manager is required.

The scripts in this reposoritory relies on the following API keys

• ALCHEMY_API_KEY
• ETHERSCAN_API_KEY
• INFURA_API_KEY.

1. Create your own .env and populate them with corresponding keys.

// sample .env file at root
MNEMONIC=""
NETWORK=""
INFURA_API_KEY=""
ALCHEMY_API_KEY=""
ETHERSCAN_API_KEY=""

2. yarn install to restore all package dependency.

3. yarn hardhat compile to compile solidity contract, create artifacts and typings.

Extensions

Following extensions are reccomended for working with this project.

1. hardhat
2. mocha test explorer
3. Prettier

High-level Project Structure

contract

Contains solidity .sol contract, compiled into bytecode and deployed to goerli test net using Deployment.ts script.

script

Contains scripts to automate contract deployment to blockchain, interact with the deployed contract. Written in TypeScript.

test

Contains unit test suite. Used to test the logic of smart contract. Use mocha and chai js.

Running Scripts

Scripts are used to automate the contract deployment as well as interacting with the deployed blockchain (e.g. calling functions on the contract).

Without parameters

yarn hardhat run .\scripts\common\GetLastestBlock.ts

With parameters

This deploy a ballot with 3 proposals "Chocolate" "Vanilla" "Mint"
