$ show PaulRBerg/hardhat-template
This repository is a Hardhat-based template for developing Solidity smart contracts. It provides a pre-configured development environment with sensible defaults for compilation, testing, linting, and deployment. The core functionality is demonstrated through a simple `Lock` contract that implements a time-locked withdrawal mechanism, complete with custom errors, events, and comprehensive tests. The template integrates TypeChain for TypeScript bindings, Ethers.js for Ethereum interactions, and various tooling like Solhint, Prettier, and Solcover. It is not a production application but a starting point for new Solidity projects, emphasizing best practices and developer experience.
The LLM identified 3 files worth highlighting for reuse:
A well-structured Solidity contract demonstrating time-locked withdrawals. It uses custom errors for gas-efficient revert reasons, emits events for state changes, and follows the checks-effects-interactions pattern. This contract serves as a clean example of Solidity best practices and can be reused as a reference for similar locking mechanisms.
A reusable test fixture that deploys the Lock contract with deterministic parameters. It leverages Hardhat's network helpers to set up the blockchain state and returns all relevant objects (contract instance, addresses, signers). This pattern can be extracted and applied to any Hardhat project to create clean, isolated test setups.
Hardhat tasks that demonstrate how to create custom CLI commands for contract interaction. The `task:deployLock` and `task:withdraw` tasks show parameter handling, signer management, and contract calls. This pattern is reusable for any project needing custom Hardhat tasks beyond the default ones.
