🚀 Challenge Overview 🚀 Damn Vulnerable DeFi V3 Challenge 6, "Selfie," is about governance mechanisms, lending pools and flash loans with DVT tokens. A governance mechanism controls everything. Our mission? Exploit vulnerabilities within these contracts and steal the 1.5 million DVT tokens from the pool.

🤖 Meet the Smart Contracts 🤖 SimpleGovernance.sol: At the core of governance, this contract allows users to propose and queue actions. Conditions must be met for execution, including votes from token holders and a 2-day time delay.

SelfiePool.sol: The flash loan provider with a safety net - governance can drain funds in emergencies. Only the governance contract can trigger this emergency exit feature.
