Top 10 Crypto Audit Companies in 2022

The Rising Market of Crypto Audit Companies

With the widespread acceptance of cryptocurrencies, the crypto audit companies’ sector is also expanding. Now that hacking incidents are on the rise; security has become even more crucial in the crypto domain. A component of blockchains requiring auditing are smart contract audits. But, what exactly is a smart contract audit?

A smart contract audit is a method for examining the code of a smart contract that interacts with the blockchain or cryptocurrency. This procedure is very important, and it is used to find bugs, problems, and security holes in the code so that they can be fixed. Doing so protects the code from potential flaws in the future and gives the safety that potential users need.

How Much Does A Crypto Audit Cost?

Depending on the complexity of the code, crypto contract auditing companies often charge up to $15,000. Although, the price may be higher in some circumstances. The auditing company creates a report detailing the potential faults of the code and offers additional suggestions to increase security.

Experts also examine contract dynamics to understand how they reflect on current security trends. A crypto audit costs a lot because reviewing the code row by row takes a lot of time and effort.

While high costs may dissuade some crypto firms from conducting an audit, it’s necessary to do one and find out if there are changes needed in the code. Failing to address issues and bugs from the start, could lead to substantially higher costs later on, and possible security issues.

What’s The Process of Performing a Smart Contract Audit by The Crypto Audit Companies?

A smart contract audit service checks for known vulnerabilities relevant to each smart contract’s specific business logic. It also determines whether the smart contract complies with the Solidity Code Style Guide and confirms that it is free of logical and access control issues.

The requirements for smart contract security audits differ amongst projects. Smart contract auditors use both manual and automatic techniques for the process.

Manual Auditing

A team of experts manually examines each line of code to check for compilation and re-entry issues. This can help spot additional security loopholes that are frequently missed, such as bad encryption techniques.

This is the most accurate method as it tracks down hidden defects, such as difficulties in design, instead of typical coding bugs.

Automated Auditing

This method of auditing uses bug detection software to help auditors identify the precise area where problems are present.

Automated techniques are frequently used for projects that plan to launch soon because it helps uncover vulnerabilities quickly. When checking code, automated software may only comprehend the context, overlooking other vulnerabilities in some cases. That’s why solely relying on such testing is risky.

The team from Mainstream Cryptos advises all crypto projects to not overlook this process and hire a company that can do both types of testing.

What Does A Good Crypto Audit Include?

Smart contracts allow the facilitation and verification of financial transactions and tracking of the movement of both physical and intellectual property.

Security and consistency are essential for smart contracts because they have the power to distribute precious resources among complex systems and are mostly autonomous.

Therefore, for smart contract security, it’s crucial to assess the possibility and seriousness of potential contract faults and discovered errors. That’s where a smart contract security audit comes in to safeguard the funds transferred through them.

Due to the irreversible nature of all blockchain transactions, money that has been stolen cannot be recovered.

To help developers quickly find loopholes and defects before implementing smart contracts, the smart contract audit focuses on looking at the code that supports the terms and conditions of the contract.

How Long Does A Crypto Audit Take?

The initial audit process can take two to fourteen days (sometimes even longer than that). The length of the process depends on the project, its size, the number of contracts, and how urgently it needs to be completed.

The audit may take up to a month for complicated projects or protocols. After the initial audit, the client is given recommendations for adopting fixes. The next step is a remediation check, which typically lasts up to a few days.

Bottom Line

Hacks and exploits are common in the cryptocurrency sector. These frauds may cost companies and individuals millions or even billions of dollars. However, as the blockchain market continues to grow exponentially and more people enter the market, crypto businesses should become more cautious and proactively use audit firms.

Our team believes that being proactive is very important for the long-term success of all companies in the industry. Without proper foundations like secured smart contracts, no crypto marketing matters.
