- Top firms in 2024 include Certik, Hashlock, ConsenSys Diligence, Cyfrin, and Hacken, each with unique strengths.
- Regular auditing is essential in the Web3 space to prevent hacks and secure smart contracts.
Smart contract auditing is a critical step in ensuring the security and integrity of your protocol, and with billions of dollars lost to bugs in the last few years, it's more important than ever.
With the circulation of great information, even users are now accustomed to checking if the smart contract audit of a protocol was done by a reputed company or not before using it.
But with so few companies offering these services, how do you choose the right smart contract auditing firm for your needs?
In this article, we'll take a look at some of the top smart contract auditing companies in 2024 and what makes them stand out.
Whether you're looking for the most comprehensive audit possible or the most cost-effective solution, we've got you covered.

Why Should You Audit Smart Contracts?
A smart contract is programmed and deployed onto the blockchain. Once it has been deployed, there is no going back.
A minor bug can break an entire protocol and a malicious user can drain out its funds within a matter of minutes. In 2022 alone, $3.8 Billion have been stolen from de-fi protocols based on a recent 2022 Crypto Crime Report shared by Chainalysis.
Recently we also saw malicious intent through the introduction of a bug directly from the person writing the actual smart contract in the first place.
However, in most instances, it is human error.
Smart contract itself is a new concept that has been there only for a few years. Only a handful of developers are very experienced in this field.
It is difficult for a developer or even a team of developers to think of every possible edge case to secure their contracts like Fort Knox. It pays a huge dividend to get a third set of eyes on your smart contracts to rule out possible issues with the code that could end up wiping all the funds inside.
Therefore, it is essential to get every piece of smart contract audited.
One of the ways to make sure your smart contracts are secure is by following a proper Web3 security journey such as the one Patrick Collins explained in his interview with us.
Right from private audits to competitive audits, everything has an important role to play in making a Web3 protocol more secure.
Let's Rewind a Bit: What Is a Smart Contract?
A smart contract is a digital agreement that is programmed and enforced on a blockchain. This was initially popularized by Ethereum, which then made its way to various other blockchains.
Through a smart contract, the developers can automate any digital contractual agreement with the right set of parameters.
Smart contracts are tamper-proof, transparent, and secure. However, as we discussed there are risks associated with using smart contracts.
How to Choose a Smart Contract Auditor Firm?
When looking to hire a smart contract auditor, you should keep a few things in mind. The first is that not all auditing companies are created equal.
Some firms have more extensive experience in auditing smart contracts than others and have the best talent.
The second thing you need to keep in mind is your requirements.
While most firms conduct smart contract audit services on the Ethereum chain, only some support other chains such as Solana or Binance Chain.
Also, you might have to choose your auditing services company depending on how thorough you want the audit to be.
The third is the cost of the audit process. Getting the most talented people to create an audit report and review your smart contract is going to be very expensive.
Some of the top auditing companies charge six figures per audit. So you might have to choose your auditing firm depending on your budget.
Another factor that comes into play here is how valuable that audit is going to be from a user perception as well as the actual security perspective.
Choose an audit firm with not much experience and they might just miss a red flag in your contract or your users might even not trust that audit at all discouraging them from using the contract in the first place.
