Definition ∞ A Cross-Chain Attack Vector is a pathway through which malicious actors can exploit vulnerabilities that span multiple distinct blockchain networks or the bridges connecting them. This method targets the interoperability mechanisms designed to facilitate asset transfers and communication between chains. Successful exploitation can result in significant asset theft or system compromise.
Context ∞ The expansion of multi-chain ecosystems has brought increased attention to cross-chain attack vectors, as these present significant security challenges for the entire digital asset space. The security of cross-chain bridges, in particular, remains a prominent concern due to numerous high-profile exploits. Developers are actively working on more secure interoperability solutions.
