Smart contracts are a crucial component of how blockchain technology is changing the game for companies in every industry. Smart contracts increase confidence between parties by removing third-party intermediaries, lowering costs while enhancing transparency. If you're building a smart contract, it's essential to audit the code to ensure it will function properly and have no flaws or security issues. Here, we will guide you through the fundamentals of auditing your smart contract and some typical smart contract flaws.
What Is A Smart Contract Audit?
A smart contract audit thoroughly evaluates a smart contract's code before deploying it. Since smart contracts are immutable, they cannot be altered after deployment. Thus, they must be carefully evaluated to rule out any problems or vulnerabilities so the project's functionality won't be compromised when launched. Hence, smart contract audits are carried out to improve the codes' efficiency and integrity.
Developers examine the contract's source code line by line as part of a smart contract audit procedure to look for security flaws or vulnerabilities. The lines of codes with errors are corrected and mended after identification. This can lower the potential hazards associated with the code and raise its quality.
Why Audit Your Smart Contract?
Smart contracts are crucial for a variety of reasons. They can assist you in streamlining and automating business procedures to save time and money. Yet the primary factor in their popularity is that eliminating human mistakes from the picture lowers the chance of fraud. The drawback of these advantages is that it's simple to make mistakes when creating a smart contract. Your system could crash due to a defective codebase, leaving you open to hacker attacks. You may be aware of hacks involving tokens based on Ethereum. These thefts happened as a result of smart contract flaws that let thieves steal cryptocurrency valued at millions of dollars that were kept inside those contracts. A smart contract audit is essential to the life cycle of the project and can assist in reducing security concerns related to the contract's code.
The Smart Contract Auditing Process
The company should adhere to specific standards and methods in an organised manner in order to carry out a proper smart contract audit. Although the auditing process's structure can vary from firm to firm, its broad layout does not change. Let's walk through a sample smart contract auditing process step by step.
Specification Gathering And Client Consultation – A smart contract audit can only take place if the project's details are thoroughly understood. Therefore, the first step in auditing a smart contract is to research the project by meeting with the customer and acquiring specifications. Our expert auditors comprehend the code's framework, design, architecture, build process, and other critical information to comprehend the smart contract's intended behaviour.
Automated Review And Testing – An auditor uses complex, high-end tools and software to review and analyse contract codes. This process examines the source code for potential hazards such as security flaws, bugs, syntax issues, and exploitable and weak code.
Manual Analysis And Testing – The manual analysis and testing phase finds errors and code flaws missed during the automatic review and testing phase. Here, the auditors go line-by-line through the code to check for any unforeseen behaviour or security problems that may be present in the smart contract.
Functional Testing – Functional testing verifies whether each contract function operates according to the specifications by testing each function and method under various settings and parameters for any errors.
Initial Audit Report Submission – The auditors submit the initial audit report after extensively examining the smart contract for any vulnerabilities. This audit outlines all the conclusions and sensible suggestions for resolving the problems.
Rectifying The Codes – Developers address the bugs found after submitting the initial audit report using the recommendations made in it. Depending on the needs of the client, the codes may be corrected.
Inspecting the fixed codes – Once developers have fixed the codes, the audit company looks through the corrected smart contract once again and performs a number of tests to verify that all bugs have been fixed and the code quality has improved.
The Bottom Line
Before smart contracts are implemented on a live network, auditing them is essential to ensuring their security, dependability, and integrity. It entails a thorough examination of the source code by qualified auditors and automated technologies to find and evaluate the vulnerable codes that malicious actors can modify. It avoids hostile attacks, data leakage, and the draining of contract assets by discovering, analysing, and repairing vulnerable codes and increasing people's trust in the contract and its related platform. In addition, performing a smart contract audit emphasises the need to avoid security issues rather than regretting them later.
