An Optimism smart contract audit involves a thorough review of the code and design of a smart contract deployed on the Optimism network—a layer 2 scaling solution for Ethereum. The audit aims to identify and address security vulnerabilities, ensure compliance with industry standards, optimize gas usage, and assess overall functionality. By undergoing this process, developers and users gain confidence in the contract's security, reliability, and efficiency, contributing to the success of Optimism in improving scalability and reducing transaction costs on the Ethereum blockchain.
