This guide gives the decision path, a settings matrix from each tool's current documentation, and a scan of what the 30 largest DeFi protocols actually keep in their repositories.

FAQ for users
Why do I need a smart contract audit of my project?
A smart contract audit is a fundamental element of blockchain security. Auditing a smart contract allows developers to learn and receive recommendations on how to eliminate all errors and vulnerabilities in the code before it is deployed to the main blockchain network. This way, you can secure your project from the attacks it may be exposed to. In addition, a smart contract audit is one of the key factors for investors when choosing a project for investing their assets. Many successful blockchain organizations order several audits of their smart contract by verified auditors in order to protect themselves and their future investors as much as possible.
How do I choose the best auditor for my project?
There are different tiers of auditors, each with its own reputation, experience, and price segment. You should start choosing by defining the price segment that suits you. Rates for different auditors can vary between $900-$2000, $3000-$10000, and even more. Then you can study and evaluate the site of the auditor's company, and how well it is designed. Be sure to visit the GitHub of the auditor you like. There you will be able to view all past reports of the projects they have audited, and determine whether they are well-known or notorious. You can study how often the audit company is mentioned in the media and in what vein. Some auditors specialize in a specific blockchain, for instance, Ethereum or TON. There are also universal auditors - you should choose an auditor with extensive development experience on the blockchain you use.
