Decentralized Finance (DeFi) and the Rise of Financial Exploits

Abstract

This chapter delves into the revolutionary emergence of Decentralized Finance (DeFi), its potential to revolutionize, and its vulnerabilities. Based on blockchain technology, DeFi bypasses conventional financial intermediaries through smart contracts to execute lending, trading, and other economic activities. The permissionless aspect of DeFi increases financial inclusion worldwide, especially for the unbanked and underbanked. Yet, this openness also exposes DeFi platforms to threats such as vulnerabilities in smart contracts, oracle manipulation, flash loan attacks, and governance attacks. Case studies like the Poly Network hack, Mango Markets manipulation, and Squid Game token rug pull illustrate these risks. The research covers technology innovations such as smart contract audits, formal verification, decentralized oracles, and AI-based threat detection to strengthen DeFi's future. It also examines how regulatory sandboxes and decentralized identification solutions can balance innovation and regulation.
