Top 5 Smart Contract Audit Companies in 2022

Smart Contract auditing is a fast-growing industry, with a lot of demand from various crypto startups in NFT, DeFi, and other spaces. However, there are very few companies that offer these services.

Introduction: What is a Smart Contract?

A smart contract is a digital agreement that is programmed and enforced on blockchain. This was initially popularised by Ethereum, which then made its way to various other blockchains. They can automate any digital contractual agreement with the right set of parameters.

Smart contracts are tamper-proof, transparent, and secure. However, there are risks associated with using smart contracts.


Why 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 drain out its funds. In the last two years alone, Billions of dollars have been lost to bugs in smart contracts.

The person who wrote the smart contract could easily create a backdoor to siphon off the funds. 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. A small mistake could easily result in billions of dollars being lost.

Therefore, it is essential to get every piece of smart contract audited.

How to Choose a Smart Contract Auditor

When looking to hire a smart contract auditor, you should keep a few things in mind. The first is that not all auditing firms are created equal. There are some firms that are more experienced in auditing smart contracts than others and have the best talent.

The second thing you need to keep in mind is your requirement. While most firms audit smart contracts on the Ethereum chain, only some support other chains such as Solana or Binance Chain. Also, you might have to choose your auditing firm depending on how thorough you want it to be.

The third is the cost of the audit. Getting the most-talented people to audit to review your smart contract is going to be very expensive. Some of the top auditing firms charge six figures per audit. So you might have to choose your auditing firm depending on your budget.
