## Bridge Security Risks

Bridge security risks involve the vulnerabilities inherent in the smart contracts and relayers that facilitate the transfer of assets between different blockchains. Because these bridges often hold large amounts of locked collateral, they are prime targets for hackers.

Exploits can lead to the total loss of user funds, creating systemic risk for the connected protocols. Understanding these risks is essential for evaluating the safety of cross-chain financial instruments.

Analysts look for rigorous audits, multi-signature requirements, and decentralized relayers to assess the security posture of a bridge. As the ecosystem becomes more interconnected, mitigating these risks is a top priority for developers and investors alike.
