## Bridge Exploits

Bridge exploits refer to the successful unauthorized access or manipulation of cross-chain bridge smart contracts, resulting in the loss of locked assets. These exploits often stem from vulnerabilities in the code, such as improper validation logic, weak multisig security, or centralized control points.

Because bridges act as massive repositories of value, they are primary targets for hackers looking to extract large sums of capital. Once a bridge is compromised, the impact can be systemic, as the value of the wrapped tokens on the destination chain may collapse, causing contagion across multiple protocols.

Securing bridges requires rigorous code audits, formal verification, and decentralized governance to mitigate single points of failure. Understanding the nature of bridge exploits is essential for assessing the risks of using cross-chain applications and the importance of infrastructure security.
