Frequently Asked Questions

How long does an audit take?
Once you submit an audit request, our team of security experts will go through it to determine the quality, size, and complexity of the codebase. Based on these factors we will provide you with an expected timeline.
How much does an audit cost?
The cost of the audit is based on the scope generated by our team when you request the audit.
Do you accept crypto payments?
Yes, we accept payment in major cryptocurrencies.
When am I ready for an audit?
We typically recommend that the audit be performed when the code is production ready, with a full-suite of unit tests and completed documentation. This helps our analysts establish a comprehensive understanding of the intended functionality of the system.
Do I need a smart contract Audit?
Fast development cycles are typically counterproductive to developing high quality, secure code. Releasing untested, unaudited code onto mainnet is irresponsible and puts yourself and your users at risk. A smart contract audit ensures that an independent team, specialized in identifying functional and security issues, assesses the code to identify issues and improve the security posture.
Why are smart contract audits necessary?
The security implications of open, programmable money are immense. In-depth security is imperative to protect platforms and their users.

Whether it's a financial tool, governance system, or game, smart contracts are inherently high risk.
