During smart contract audits, the source code of cryptocurrency projects is examined to uncover any security problems. As a result of the emergence of smart contracts, a vital component of the cryptocurrency ecosystem, blockchain technology has a vast array of uses.

However, programmers who produce code rapidly must prioritize security above all else. Intelligent contract vulnerabilities may put users’ funds at risk, and we’ve all heard of high-profile breaches that led to the theft of vast sums of money.

A neutral entity can uncover faults in a smart contract by putting it through its paces and conducting an audit, allowing them to do so before malicious actors. Since modifying innovative agreements after being uploaded to a network may be challenging, audits are often performed before their distribution. This may assist cryptocurrency efforts in gaining a favourable image and provide users with a feeling of security.

Like Ethereum and Solana, blockchains are often the sole locations where smart contracts exist.

How precisely is an Ethereum smart contract audit conducted?

The most respected security businesses subject their code to thorough testing to see how well it performs under several circumstances.

According to the thoughts of industry experts, a project must have a thorough and comprehensible technical definition. In an ideal world, it should also contain documentation of the deployment procedure. In addition to identifying vulnerabilities that black hat hackers may exploit, these audits also look for flaws that might prevent an Ethereum smart contract from operating as intended.

Replay attacks, in which hostile actors undertake repeated lawful data transfers to conduct fraudulent activities, are one of the attack vectors being explored at present. Other instances include reordering attacks, re-entrancy attacks, and short address assaults. This kind of assault might grow very complex.

After the investigation is complete, the developers of a crypto project get a comprehensive analysis of the vulnerabilities inside the code, along with recommendations on how to mitigate or eliminate the problems. As a result, the amount of money saved by an effective audit often surpasses the cost… moreover, this protects the individual’s image.

Are Solana smart contract audits different?

Depending on the blockchain code they are done on, audits of smart contracts will seem slightly different.

“Missing ownership checks” is one of the most prevalent sorts of Solana security issues. This vulnerability enables attackers to escape access restrictions by manipulating settings.

And even though smart contracts may call functions from other external smart contracts, validation flaws may allow black-hat hackers to provide malicious inputs that alter how the system operates. The major auditing firms will evaluate a Solana smart contract’s documentation, security, architecture, and code quality. Additionally, vulnerabilities are assigned a severity level, allowing business-critical issues to be resolved first.

What are the benefits of performing audits of cryptocurrency projects’ smart contracts?

Audits are necessary to iron out any bugs in a cryptocurrency project and ensure that the code is appropriate for public usage. In only the first three months of 2022, hackers stole $1.3 billion in 78 different incidents. On the Ethereum and Solana blockchains, almost two-thirds of these attacks were executed.

In addition, how would a smart contract review have specifically aided them?

One of the most common reasons is that cryptocurrency initiatives place a premium on speed but fail to account for sufficient time for a thorough audit by a credible service provider.

They might also rely on the teams they employ inside the organization to conduct security checks. And although this seems to be a wise financial decision, there is a danger that firm personnel is not up to date on the most current hacking techniques used by malicious actors. Some individuals will inevitably believe they are invincible, despite knowing differently. However, the greatest threat in the bitcoin industry is complacency, and even the most well-designed businesses are vulnerable to hacking.

How much does an audit of asmart contract cost?

As expected, this depends on a smart contract’s sophistication.

According to Hacken, this figure may increase to $500,000 for larger projects with a more significant number of lines of code, not least because it will need more engineering hours. The company argues that these costs are negligible compared to the potential economic damage that a smart contract vulnerability may cause.

According to the data provided by Hacken, eighty per cent of the issues affecting decentralized applications in 2021 were attributable to smart contracts, resulting in $6.9 billion in losses. When we examine this data in further detail, we see that the average cost of each project is $47 million. Today, the amount of $500,000 appears far more plausible.

So far in 2022, over sixty per cent of the company’s consumers have used Ethereum.

And here’s how much it can make a difference: An audit revealed that eighty per cent of the projects have at least one severe fault. However, according to Hacken, only 75% of organizations have fully implemented an audit report in the past; the other companies either disregard the findings or accept a portion of the recommendations. As a direct result, their security rating deteriorated.

How long does an audit of a smart contract take?

A few weeks, give or take, depending on how quickly a crypto project grows.

If time is of the essence, these investigations may be conducted more swiftly. Depending on the complexity and breadth of a smart contract, according to Hacken, first audits might take between two and fourteen days… Again, more extensive treatments might take up to a month due to the different stages required.

At this point, suggestions will be made on which elements of the project want improvement, and the pace at which these recommendations are executed will depend on these proposals. Auditors like Hacken will conduct a remediation check to validate that all vulnerabilities have been fixed to an acceptable level.
