## What it is
A boilerplate starter kit for developing, testing, and deploying Chainlink-powered Solidity smart contracts using the Hardhat development environment. It includes example implementations of Chainlink Price Feeds, VRF (Verifiable Random Function), and Automation, along with testing, deployment, and verification tooling.

## Use cases
- set up a Hardhat project with Chainlink price feeds
- deploy and test Chainlink VRF contracts
- get started with Chainlink Automation in Solidity
- boilerplate for Ethereum smart contract development with Hardhat
- verify contracts on Etherscan from a Hardhat project
- run local blockchain networks and fork mainnet for testing
- estimate gas and run code coverage for Solidity contracts

## When to choose
- you are starting a new Solidity project that uses Chainlink services
- you want ready-made examples of Price Feeds, VRF, and Automation
- you prefer Hardhat as your Ethereum development environment
- you need a quick scaffold with testing, deployment, and verification scripts included

## When to avoid
- you need Chainlink Functions instead of the core features (use the functions-hardhat-starter-kit)
- you use Foundry rather than Hardhat
- you want a production application rather than a learning/boilerplate template
- you are building non-Ethereum or non-Solidity blockchain projects
