Smart Contract Auditors [20 Best Companies & Freelancers]

Smart contract auditors can do wonders for your ICO.

But why let someone else do the auditing right?

Because when you rely on an external smart contract auditor to develop your smart contract, your smart contract security check will be especially prioritized.

There have been hundreds of cases of hacked smart contracts and lost funds.

Reasons to use smart contract auditor and security check include:

  • Determining if the code is secure for money exchange,
  • Validating and verifying wallet address (for typographic errors and such),
  • Spotting potential bugs, and
  • Detecting vulnerabilities and errors in the code

And all that can be exploited to extract user data or even steal all the funds raised in the ICO process.

It’s in your best interests to use these well renowned smart contract security auditors to make sure none of the above will happen when it’s time to launch your ICO.

Although this list has some of the best smart contract auditors, you have to see who suits your needs best and choose wisely 😉
