What it does

Damn Vulnerable DeFi provides security challenges covering contracts and decentralized-finance mechanisms.

Choose a challenge and follow its repository instructions for setup and rules. The topic range includes oracles, governance, lending and upgradeability. This suits studying contract behavior with an explicit exercise objective, rather than treating a deployed financial system as a practice environment.
