Does this skill require Slither to be installed?

While it can perform manual code analysis, having Slither installed allows the skill to run automated conformity checks and property-based testing for more robust results.

How does this help with DeFi protocol development?

It identifies accounting mismatches and integration risks before they reach mainnet, specifically highlighting where safe transfer wrappers or balance checks are missing.

Is it compatible with ERC721 (NFTs)?

Absolutely. It includes specific assessment categories for ERC721 conformity, metadata immutability, and common NFT integration risks like reentrancy.

Can it analyze tokens already deployed on-chain?

Yes, if provided with a contract address and platform, it can query on-chain data for scarcity analysis, holder concentration, and current configuration.

What are 'weird token' patterns?

These are non-standard behaviors in common ERC20 tokens, such as USDT's lack of return values or fee-on-transfer logic, that often lead to critical vulnerabilities in DeFi protocols.

Seguridad y Pruebas

Performs deep security audits of smart contract tokens and protocol integrations using the Trail of Bits checklist and Slither analysis.

The Token Integration Analyzer is a comprehensive security tool designed for smart contract developers and auditors to evaluate ERC20 and ERC721 implementations. It systematically identifies over 20 non-standard 'weird token' patterns—such as missing return values in USDT or fee-on-transfer logic—while assessing owner privileges, contract complexity, and on-chain scarcity. By integrating Slither checks and automated property testing, it ensures that protocols interacting with arbitrary tokens remain secure against common integration vulnerabilities and edge cases.
