## Smart Contract Vulnerabilities

Smart contract vulnerabilities are flaws or weaknesses in the computer code that governs decentralized applications and financial protocols. These vulnerabilities can be exploited by malicious actors to drain funds, manipulate transaction outcomes, or freeze assets indefinitely.

Common issues include reentrancy attacks, integer overflows, and improper access controls that allow unauthorized users to trigger sensitive functions. Because smart contracts are immutable once deployed, fixing these flaws often requires complex migration processes or emergency governance intervention.

In the context of derivatives, a vulnerability in the margin engine can lead to incorrect liquidation triggers or mispriced collateral. These risks are exacerbated by the composability of DeFi, where a single exploited contract can trigger a cascade of failures across multiple integrated platforms.

Security audits are a standard, though imperfect, defense against these technical risks. Constant monitoring and formal verification are essential to minimize the surface area for potential exploits.
