Drawbacks of Certik

It is essential to note that there may be some disadvantages or drawbacks associated with their services. Here are a few to consider:

High costs for audits and other services

CertiK’s audits are priced at a premium and may be beyond the budget of small or new crypto projects. Their website states that the minimum audit fee is $15,000, with an average fee of $25,000. Still, the actual cost may vary depending on project complexity, size, and urgency. This might be a deal breaker for some users.

Limitations in fixing vulnerabilities

CertiK’s audits do not guarantee complete security or fix any identified issues. Their primary role is to identify and report vulnerabilities while offering recommendations for improvement.

Ultimately, project owners are responsible for implementing the report and suggested solutions and ensuring the quality of their code. Additionally, it is essential to note that CertiK’s audits and reviews may not cover every possible scenario, potentially missing some edge cases or unknown attacks.

Reputational concerns due to BSC hacking

CertiK’s reputation may be affected by specific incidents or controversies involving audited projects. For instance, there have been instances where projects, such as Spartan Protocol on Binance Smart Chain, were hacked for significant amounts of funds shortly after being audited by CertiK.

Such incidents have raised questions about the quality and credibility of CertiK’s audits, with some users holding employees of the firm accountable for the exploits.

Another example is SafeMoon, a popular yet controversial token that engaged CertiK to review an audit report. Certain users have criticized CertiK, accusing them of endorsing scams or promoting a potentially fraudulent money back or pyramid scheme due to their association with SafeMoon.
