Definition ∞ A bridge vulnerability represents a security flaw within a cross-chain bridge protocol. Such weaknesses can permit unauthorized access, manipulation of assets, or complete compromise of funds transferred between distinct blockchain networks. These flaws often arise from errors in smart contract code, protocol design, or operational security procedures. Exploitation of these vulnerabilities typically results in substantial financial losses for users and the protocol.
Context ∞ Bridge vulnerabilities are a persistent concern in the digital asset space, regularly reported in news when significant exploits result in asset theft. The security of cross-chain transfers remains a primary discussion point for blockchain interoperability solutions. Mitigating these risks involves rigorous auditing, formal verification, and continuous security enhancements to protect user funds and maintain network integrity.
