## Bridge Attack Vectors

Bridge attack vectors are the various methods by which hackers can compromise the security of a cross-chain bridge to steal assets or manipulate the state of the system. These vectors include compromising the private keys of the bridge's multisig, exploiting vulnerabilities in the smart contract logic, or attacking the consensus mechanism of the validator set.

Because bridges hold large amounts of capital, they are high-value targets, and attackers often spend significant resources identifying flaws in the implementation. Other vectors include social engineering of the developers or validators, or exploiting the delay between the initiation of a transaction and its finality on the destination chain.

Mitigating these risks requires a defense-in-depth approach, combining secure code, decentralized governance, and constant monitoring for anomalous activity. Understanding these attack vectors is the first step toward building bridges that can withstand the adversarial environment of the DeFi ecosystem.
