Can I test my contracts against real mainnet data?

Absolutely. The skill includes advanced patterns for mainnet forking, allowing you to interact with existing production protocols like Uniswap or DAI in a simulated local environment.

Is CI/CD integration supported?

Yes, the skill provides ready-to-use GitHub Actions configurations for automated testing, coverage reporting, and Etherscan verification on every commit.

Does this skill support both Hardhat and Foundry?

Yes, it provides configuration patterns and testing examples for both the Hardhat JavaScript/TypeScript environment and the Foundry Solidity-native framework.

How does this help with gas optimization?

It includes configurations for gas reporters that track the cost of every transaction in your test suite, helping you identify and refactor gas-heavy functions to save user costs.

Security & Testing

Standardizes the creation and execution of comprehensive test suites for Solidity smart contracts using Hardhat and Foundry.

About

This skill provides a robust framework for validating blockchain protocols through unit testing, integration testing, and advanced simulation techniques. It enables developers to implement mainnet forking for realistic DeFi protocol validation, perform property-based fuzzing with Foundry to catch edge cases, and optimize gas consumption through detailed reporting. By integrating best practices for contract verification and automated CI/CD workflows, it ensures that smart contracts are secure, efficient, and production-ready before deployment to any EVM-compatible network.

Key Features

Property-based fuzzing to identify edge-case vulnerabilities
Dual-framework support for Hardhat (JS/TS) and Foundry (Solidity)
Automated gas optimization reports and usage tracking
0 GitHub stars
Mainnet forking for realistic protocol interaction testing
Pre-configured CI/CD workflows for GitHub Actions

Use Cases

Developing unit tests for ERC-20 and ERC-721 token contracts
Auditing smart contract security through automated fuzzing and reentrancy checks
Validating complex DeFi protocol logic using mainnet state forks
