Which blockchain networks does this skill support?

While primarily focused on EVM-compatible chains like Ethereum, the security principles and tools (Hardhat, Foundry, Slither) apply to most Solidity-based blockchain ecosystems.

Which security tools does it integrate with?

The skill provides patterns and guidance for Slither, Mythril, Manticore, Echidna, and popular testing frameworks like Hardhat and Foundry.

Can I use this for DeFi-specific testing?

Yes, it includes specialized modules for testing flash loan logic, price oracle manipulation, MEV resistance, and liquidity pool vulnerabilities.

Does this skill replace professional smart contract audits?

No, it is intended to be a powerful automated assistant for developers and researchers to identify common flaws early in the development lifecycle and during internal testing.

Is it helpful for NFT projects?

Absolutely. It covers NFT-specific vulnerabilities such as royalty bypasses, minting reentrancy, and metadata manipulation risks.
