SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill systematically analyzes your codebase for token-related security concerns, ensuring your smart contracts correctly implement and integrate with ERC20/ERC721 tokens, and mitigating risks from non-standard token behaviors.

Core Features & Use Cases

  • Token Implementation Analysis: Verifies ERC20/ERC721 conformity and identifies non-standard behaviors.
  • Token Integration Security: Assesses how your protocol handles arbitrary tokens, including "weird" patterns.
  • On-chain Scarcity & Configuration Analysis: Queries deployed contracts for distribution, supply, and owner privileges.
  • Risk Assessment: Identifies vulnerabilities and provides prioritized recommendations.
  • Use Case: A DeFi protocol integrating multiple ERC20 tokens can use this Skill to ensure it safely handles fee-on-transfer tokens, tokens with missing return values, and other edge cases, preventing potential exploits and financial loss.

Quick Start

Use the token-integration-analyzer skill to analyze the security of the ERC20 token implementation in the provided codebase.

FAQPage Schema
How do I check my DeFi protocol for ERC20 token integration vulnerabilities?▼

To check ERC20 token integration vulnerabilities, you need an analysis tool that assesses how your protocol handles arbitrary tokens and identifies over 20 known "weird" token patterns like fee-on-transfer tokens, preventing potential exploits.

What are common non-standard ERC721 behaviors I should audit in my smart contracts?▼

Common non-standard ERC721 behaviors to audit include contract composition anomalies, excessive owner privileges, and on-chain scarcity manipulation, which can be identified by evaluating token implementations against established standards.

How does smart contract analysis handle fee-on-transfer tokens?▼

Smart contract analysis handles fee-on-transfer tokens by evaluating your protocol's contract composition to ensure it safely accounts for token balance discrepancies, mitigating financial loss risks from these non-standard token behaviors.

Can I analyze token security across different EVM chains?▼

Yes, you can analyze token security across different EVM chains by using context-aware analysis tools that query deployed contracts for distribution, supply, and owner privileges regardless of the specific blockchain environment.

When do I need a token security audit for missing return values?▼

You need a token security audit for missing return values when your DeFi protocol integrates external ERC20 tokens, as failing to handle these non-standard behaviors can lead to silent transaction failures and potential exploits.

What is the best way to verify on-chain scarcity and token configuration?▼

The best way to verify on-chain scarcity and token configuration is to query deployed contracts directly, analyzing supply distribution and owner privileges to ensure the token adheres to required security standards.
