Can I perform mainnet forking with this skill?

Absolutely. It includes specific patterns for forking mainnet state to test interactions with existing protocols like Uniswap or MakerDAO in a local environment.

Does this skill support both Hardhat and Foundry?

Yes, it provides comprehensive setup guides, configuration files, and testing patterns for both the Hardhat (JavaScript/TypeScript) and Foundry (Solidity) frameworks.

Can I use it to verify contracts on Etherscan?

Yes, it provides the necessary scripts and CLI commands to automate the verification of your deployed contracts on Etherscan and other block explorers.

How does it help with gas optimization?

The skill includes configurations for hardhat-gas-reporter and patterns to compare gas usage between different implementation versions to ensure maximum efficiency.
