## What it is
A curated, chronological list of reentrancy attacks on Ethereum smart contracts, maintained as a GitHub repository. It documents each attack with dates, victim and exploit contract addresses, transaction links, and post-mortem write-ups.

## Use cases
- research historical reentrancy attacks on ethereum
- find post-mortem writeups of smart contract exploits
- study reentrancy attack patterns like read-only and cross-contract reentrancy
- audit smart contracts for known reentrancy vulnerabilities
- build a security training curriculum on solidity exploits
- look up victim and exploit contract addresses for a specific hack

## When to choose
- you need a comprehensive historical reference of reentrancy incidents
- you are a smart contract auditor or security researcher studying attack patterns
- you want verified on-chain links (contracts, transactions) for each exploit

## When to avoid
- you need an automated reentrancy detection or analysis tool
- you want coverage of non-reentrancy exploit classes like flash loan or oracle attacks
- you need a runnable library rather than documentation

## Facets
- artifact type: learning-resource
- maturity: active
- function: security, documentation
- domain: blockchain, security
- platform: -
- tags: reentrancy, smart-contracts, ethereum, solidity, exploit-database, awesome-list, cryptocurrency, web-server
