Lending Protocol Security Audit

Challenge Overview

Lending Protocol Security Audit is a Capture The Flag (CTF) challenge focused on finding security vulnerabilities in Ethereum's Smart Contract and DeFi implementation.

Background

This lending protocol allows users to deposit assets as collateral and borrow other assets against that collateral. The protocol includes features like variable interest rates, liquidations, and flash loans.

Objectives

• Identify vulnerabilities in the lending smart contracts
• Find potential exploits in the collateral and liquidation mechanism
• Discover any issues with the interest rate model
• Identify flash loan attack vectors

Resources

• GitHub Repository - Source code for the protocol
• Documentation - Technical documentation and architecture
• Testnet Deployment - Deployed contracts on Goerli testnet
