Multi-Chain Exploit

Definition ∞ A multi-chain exploit is a security breach that affects digital assets or protocols operating across several different blockchain networks simultaneously. This type of attack often leverages vulnerabilities in cross-chain bridges or shared infrastructure, allowing attackers to compromise assets on multiple ledgers through a single coordinated action. Such incidents can have cascading effects.
Context ∞ The increasing prevalence of cross-chain interoperability solutions has unfortunately also expanded the surface area for multi-chain exploits. Security incidents targeting these bridges have resulted in substantial financial losses, prompting renewed focus on the security architectures of inter-blockchain communication protocols. The complexity of securing multi-chain environments remains a significant challenge for the industry.
