Code review is a software quality-assurance activity in which one or several people manually review source code.

In our audits, we carefully study the codebase line by line, often several times, to reach the following goals:

  • complete understanding of the system, protocol, or smart contract
  • finding bugs, defects, and minor issues
  • identifying potential gas optimizations
  • proposing code improvements based on our knowledge of good programming practices
  • finding better solutions
