How does mainnet forking help in testing?

Mainnet forking allows you to test your contracts against real-world state and existing protocols like Uniswap or Aave without spending actual ETH on a live network.

Does this skill support both Hardhat and Foundry?

Yes, it provides comprehensive setup guides and code patterns for both Hardhat (JavaScript/TypeScript) and Foundry (Solidity) testing environments.

Can I use this for gas optimization?

Absolutely. The skill includes specific patterns for comparing gas usage between different implementations and using tools like the Hardhat gas reporter.

Does it include CI/CD support?

Yes, it provides pre-configured GitHub Actions workflows for automated testing, compilation, and coverage reporting on every commit or pull request.

Can this help with contract verification?

Yes, the skill includes scripts and CLI commands for programmatically verifying your smart contracts on block explorers like Etherscan.
