DeFi exploit losses in H1 2026 range from $840 million to $1.3 billion, with a shift from smart-contract bugs to access-control and permission failures in cross-chain infrastructure becoming the leading attack vector. The role of state-backed actors is significant, and the evolving attack surface raises fresh security challenges for protocols relying on shared cross-chain standards.
This Wire brief sits within Fusion42's coverage of Crypto & Web3.
