The discovery of high-severity issues in a code is the primary purpose of a crypto audit. Before performing an audit, the crypto audit company's security team must first have a thorough grasp of the project's architecture and use cases, as well as recognize the target system's main components. The last part of an audit allows for the exploitation of discovered vulnerabilities in order to assess the scale of possible risks that a project under test could face, as well as their correction.

Token audits performed by crypto audit firms enable projects to avoid the exploitation of vulnerabilities that might lead to the loss of client funds. Furthermore, the fact that a project has passed a crypto audit will serve as a strong indication to consumers of the project's commitment to security. To perform an audit, the company's team will learn about the project in-depth to produce a document in which they will describe the discovered vulnerabilities and evaluate the level of risk and give ideas for correction.
