Faq

A blockchain 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.
Blockchain audits are 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.
The duration 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.
Some common vulnerabilities include reentrancy attacks, overflow and underflow errors, unchecked external calls, and issues in access control, among others.
Initial audits are essential before launch. However, subsequent audits should be considered after significant updates, or annually to ensure evolving security standards are met.
