## What it is
A curated collection of 859+ DeFi hack incidents reproduced as Foundry proof-of-concept tests in Solidity, for studying how real exploits worked. It also includes a Web3 cybersecurity academy with on-chain transaction debugging lessons and root cause analyses.

## Use cases
- learn how past DeFi hacks happened
- reproduce blockchain exploit incidents in Foundry tests
- study smart contract vulnerability root causes
- practice on-chain transaction debugging
- train for smart contract security auditing
- find proof-of-concept code for historical DeFi attacks

## When to choose
- you want hands-on, executable reproductions of real DeFi exploits
- you are learning Solidity security auditing or on-chain debugging
- you need a large, actively updated corpus of hack case studies

## When to avoid
- you need a production security scanning or auditing tool rather than educational PoCs
- you want a general-purpose Solidity testing framework (use Foundry directly)
- you are looking for defensive tooling like automated vulnerability detection

## Facets
- artifact type: learning-resource
