Faq

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.
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.
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.
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
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.
