faq
- What is a blockchain security audit?
A blockchain or smart contract security audit is a thorough examination of a blockchain application, often focused on smart contracts, to identify vulnerabilities and ensure that it functions as intended without any security flaws.
- Why is a smart contract audit necessary?
Smart contracts audit is crucial to ensure the safety of funds and user data, to maintain the trustworthiness of a decentralized system, and to prevent potential exploits or attacks that could compromise the network or its participants.
- What's the difference between a manual audit and an automated audit?
A manual audit involves human experts analyzing the code for vulnerabilities, while automated audits use tools to scan for known issues. A combination of both methods often provides the most comprehensive results.
- How do I prepare my project for a security audit?
Ensure your code is well-documented, provide clear specifications of your project’s functionality, and share any previous audit reports or identified concerns with the auditing team.
Check our Pre-Audit Tips - How long does a typical smart contracts security audit take?
The duration of a smart contracts audit varies based on the complexity of the application and depth of the audit. Typically, it can range from a few days for simple contracts to several weeks for intricate systems.
- What are the common vulnerabilities found in blockchain applications?
Some common vulnerabilities include reentrancy attacks, overflow and underflow errors, unchecked external calls, and issues in access control, among others.
- How often should I get my blockchain application audited?
Initial audits are essential before launch. However, subsequent audits should be considered after significant updates, or annually to ensure evolving security standards are met.
- Can an audit guarantee my smart contract is 100% secure?
No audit can provide an absolute guarantee due to the evolving nature of threats. However, a thorough audit significantly reduces the risk of vulnerabilities and exploits.
- What happens if vulnerabilities are found during the audit?
If vulnerabilities are detected, the auditing team will provide detailed feedback on the nature of the issues and recommend fixes. It’s essential to address these vulnerabilities before going live.
- Are all blockchain platforms equally vulnerable?
Different blockchain platforms have distinct architectures and functionalities, which may expose them to different types of vulnerabilities. However, no platform is inherently immune; the security largely depends on its implementation and the robustness of its code.
