DeFi Security

DeFi security encompasses smart-contract vulnerabilities, private-key management, cross-chain bridge risks and protocol governance. Summer.fi, Polymarket and Drift Protocol have recently suffered attacks in succession, while flash loans and contract vulnerabilities continue to cause asset losses. The infiltration of North Korean IT workers, private-key leaks and security controversies involving LayerZero also highlight personnel and infrastructure risks. As AI lowers barriers to launching attacks and accelerates vulnerability discovery, monitoring attack methods, defensive measures and protocol migrations can help assess asset security and systemic risk in DeFi.
