Understanding the Importance of Smart Contract Audits
A smart contract audit is a thorough examination and analysis of the code of a smart contract used for interacting with cryptocurrencies or blockchains. The main goal of this process is to identify any errors, issues, or security vulnerabilities in the code and provide recommendations for improvements and fixes. Smart contract audits are especially crucial because these contracts often involve financial assets and valuable items.
Conducting these audits can be complex due to the interconnected nature of smart contracts and their potential vulnerabilities when integrated with third-party systems. As a result, the audit process often extends to other smart contracts involved in interactions, including those that interact with the initial contract. These audits typically involve running tests and manually analyzing the code.
Since smart contracts often manage significant amounts of funds, even a single bug or vulnerability can result in substantial losses. Users and stakeholders of the decentralized application associated with the contract could potentially lose all their assets within the ecosystem.
The recommendations provided by auditors are shared with the project team in advance, and their actions in response are documented in the final report. This audit report serves as proof of the project’s authenticity and integrity, helping to build user confidence and enhance the project’s credibility. Smart contract audits are usually conducted in multiple stages.
The first step involves the project team and the auditing group agreeing on the scope and specifications of the audit. This includes sharing details about the design, purpose, architecture, and other relevant aspects of the smart contract with the auditors. The testing phase follows, during which the auditors conduct unit tests to assess individual functions and integration tests to evaluate larger sections of the contract.
Automated bug detection and analysis tools are also used to identify commonly known vulnerabilities in the contracts. Finally, auditors manually review the code to understand the developer’s intentions and interpret their findings within that context. The audit concludes with the issuance of a report that outlines the identified issues and the fixes implemented by the project team.
The significance of smart contract audits can be seen in the Ethereum chain split in 2016, which occurred due to a code vulnerability exploited by an attacker. This vulnerability allowed the attacker to drain millions of dollars’ worth of ETH from the “DAO” democratized hedge fund. The subsequent debates within the community regarding whether to forcibly return the funds resulted in disagreements and a hard fork.
In the rapidly growing DeFi industry, smart contract audits have become increasingly important. Many bug-ridden smart contracts are hastily released to meet investor demand, leading to numerous costly hacks in 2020. Notable examples include Harvest, Yam Finance, bZx, Balancer, and Eminence.
