# Why is smart contract audit important?

Smart contracts are self-executing codes that usually deal with financial and other valuable assets and tokens. Since blockchain is an immutable ledger, a smart contract, once deployed, cannot be altered. Hence, it is vital to audit a smart contract for its vulnerabilities and debug complex codes that often interact with each other, integrating a third-party system that makes the project susceptible to hacking and cybercrimes.
