Web3 security flaws and AI agents reshape DeFi landscape

Analysts note that most DeFi losses in 2024 stem from off‑chain human vulnerabilities rather than smart‑contract bugs. Halborn data show 56.5% of attacks and 80.5% of stolen funds originated from issues such as private‑key compromises, bridge‑validator failures and social‑engineering tricks. Experts argue that labeling all incidents as “DeFi hacks” obscures the true cause and hampers effective remediation.

Optimism co‑founder Karl Floersch proposes autonomous AI agents to simplify Web3 interaction, handling tasks like trading, contract deployment and on‑chain coordination. He suggests that AI agents could become primary participants in blockchain economies, increasing demand for Layer‑2 throughput and raising new governance, security and regulatory challenges.
