reentrancy

To detect reentrancy vulnerabilities in Solidity smart contracts, you can analyze the code for CEI violations, cross-function and cross-contract reentrancy, read-only reentrancy, and token callback exploits. This process generates a State Timeline map showing state changes during an attack.

A State Timeline map in smart contract security auditing is an artifact that visualizes the sequence of events and state changes occurring during a reentrancy attack. It helps auditors understand how vulnerabilities like CEI violations and token callback exploits are exploited step by step.

Yes, cross-function and cross-contract reentrancy can be detected automatically in Web3 security by scanning the Solidity codebase for common reentrancy patterns. The analysis identifies attack vectors across different functions and contracts to speed up the security audit process.

Read-only reentrancy detection requires providing the Solidity smart contract codebase for analysis. The Skill operates without external dependencies to identify read-only reentrancy and token callback exploits, outputting a State Timeline map for each vulnerability finding.

The best way to identify CEI (Checks-Effects-Interactions) violations during a smart contract audit is by analyzing the Solidity code specifically for reentrancy patterns. This approach pinpoints CEI violations and generates a State Timeline map to track state changes during the vulnerability.

Token callback exploits identifiable in smart contract security include those interacting with external contracts to trigger reentrancy. The analysis detects these token callback exploits alongside CEI violations and read-only reentrancy, providing a State Timeline map for each vulnerability found.
