Security and audits

Last reviewed · about a 7-minute read

Security in DeFi has two halves. One is the code: has it been reviewed by people who know how to break it? The other is you: can you avoid the scams that target users directly? Frax has a long audit history on the first; this page covers it, and then gives you the habits that handle the second.

The audit history

Frax has been reviewed repeatedly since launch, by several of the better-known firms in the space, and more recently by its own dedicated security group. The table below summarizes the public record. For the audit reports themselves and any work newer than this page, see the official documentation.

What an audit does and does not mean

An audit is a skilled review at a point in time. A clean report is meaningful evidence of diligence, but it is not a guarantee that code is bug-free, and it does not cover changes made afterward. Read audits as one input into your own risk judgment, alongside the risks page — not as a green light.

Protecting yourself from phishing

Here is an uncomfortable truth: most people who lose crypto are not victims of a contract exploit. They are tricked into handing over access. The attacker does not need to break the code if they can fool the person. These habits prevent the large majority of those losses.
