DeFi is on its way to becoming the new financial system, much like web 3.0 has become the new Internet. As a result of this, DeFi has its unique dangers, including smart contract risk. Audits of DeFi projects’ smart contracts could have helped to avert such a situation.
Performing a DeFi audit is becoming a critical tool for firms looking to assure the integrity and security of their blockchain-based initiatives for users. Financial institutions, in particular, should place a high value on the safety of their customers’ personal and financial information when conducting business online. For people to put their faith in these services, the code that powers them must be flawless and exceed rigorous safety standards.
Businesses use DeFi Smart Contract Audit to ensure their deployed code is error-free. As a means of evaluating the investment potential of cryptocurrencies, investors are keenly interested in the findings of smart contract verification. Let’s know about it in a detailed manner.
What is DeFi Smart Contract Audit?
DeFi, Decentralized Finance, refers to a wide range of cryptocurrency and blockchain-based financial applications to displace traditional financial intermediaries. In light of the alarmingly high number of industry hacks and frauds, audits or formal verifications are urgently required before putting your code to the mainnet. Because the decentralized financial system relies on smart contracts to run automatically, any faults identified in their code could jeopardize its seamless operation.
A DeFi safety audit is a detailed examination of the code by auditors to prevent this from happening in the first place. Third-party auditors conduct this audit, ensuring an unbiased assessment of the code.
How Does DeFi Smart Contract Audit Work?
The auditors examine the documentation, website, and software repository to find any flaws in the code or issues with the implemented smart contracts. The auditing firm provides a summary and a report containing a thorough review of the project’s security and compliance with the whitepaper. For the DeFi projects, there are several stages in the smart contract audit process:
It can be done by examining the DeFi software’s white/yellow paper to discover the business logic and evaluate the risk coverage and security properties.
Automating Code Verification
Typically used in conjunction with automated programs that scan for well-known flaws in the source code.
Review Manual Code
To ensure that the code is safe, experts undertake a series of tests to see whether there are any significant vulnerabilities.
Prepare a Thorough Audit Report
Finally, this stage analyses the smart contract’s weaknesses in great depth. It includes suggestions for reducing the threat.
Your project’s integrity will be ensured before its launch if these measures are followed to conduct a thorough audit.
How is Smart Contract Audit Beneficial for DeFi Projects?
An audit of the tokens is necessary to protect investors’ money and ensure the project’s long-term viability. You can save millions of dollars by ensuring the safety of your project before it goes into production.
Your blockchain initiatives will benefit from smart contract audits performed by highly experienced experts with the use of automated technologies, as follows:
- Make sure the code and white/yellow paper are in sync
- Avoid being hacked by securing the assets
- Assure the project’s integrity
Types of Issues Resolved By DeFi Smart Contract Audit
Undergoing DeFi Smart Contract Audit ensures that the audit is more comprehensive than just looking for code flaws to fix. Other tests are undertaken to guarantee that the smart contract code is not vulnerable to assaults like flash loan attacks or more. On the other hand, the majority of the audit work focuses on finding security flaws. First, let’s have a look at some of the most typical flaws:
The fallback function is a feature of smart contracts. The indirect execution occurs if this function is called by mistake. One can invoke the fallback function in multiple ways. Calling another contract’s ABI function, depositing to another contract that could generate a fallback, or a coder making a mistake when declaring the interface of a called contract is all examples.
When a smart contract calls another smart contract, it’s usually referring to an external contract. However, before any effects have been resolved, the external contract may be invoked recursively. It can then interact with the smart contract in ways it can be a security threat.
Overflowing or Underflowing Integers
There are several instances of this type of coding error. Operation results are stored in operands at every step of the calculation. An integer overflow mistake can lead to erroneous code execution, which occurs when the result’s decimal places exceed the operand’s decimal places.
Stay on Front
Hackers can leverage a poorly written smart contract code to expose the details of any token purchases or sales. The release of this information can then influence these trades.
Besides looking for bugs in the code, the DeFi Smart Contract Development aims to make the contract more efficient in general. As a result, the smart contract audit reports include audits of such things as:
Efficient Gas Fees
Gas fees are charged for each time the execution of the smart contract’s code occurs. Consequently, the smart contract audit reports can assist developers in optimizing their smart contracts by detecting wasteful actions or sites of failure that may lead to increased gas expenses.
Platform Security Defects
An audit of a smart contract looks beyond the code and analyses the platforms or APIs that use that smart contract. The API or platform that the smart contract communicates with may make it vulnerable to attack even if the contract itself is impenetrable.
Increasing Demand of DeFi Smart Contract Audit
Audit services in the DeFi industry are in high demand as the market continues to rise. Demand for smart contract audits has skyrocketed as the decentralized sector value has grown tremendously since the recent surge in DeFi popularity.
Prior to the launch of a new platform, audit firms are inundated with requests from projects that want to fix problems and vulnerabilities. A large number of applicants force large security businesses to turn off projects. After a while, the market reaches a point where it can no longer sustain itself.
Organizations need to select auditors with the necessary experience and qualifications in the ever-growing field of auditing solutions. The first step in ensuring the security of smart contracts is to perform a DeFi audit. As a result, audited solutions may become the next big thing in the near future because it will be easier to secure insurance for them.
A comprehensive smart contract audit has become necessary as a result of multiple high-profile projects incurring large financial losses. There is no way to know for sure that your smart contract will always be safe from new threats, even if it is audited. DeFi’s progress is influencing the evolution of the audit rules. In some cases, relying on a DeFi Development Company can be the best choice as they are always updated about the new developments in the same industry. Suffescom Solutions can help you with their best-in-class smart contract services to perform auditing for your DeFi project. Consequently, performing regular audits should be your first choice.
