Blockchain technology ensures that security is a prior subject for investors and individuals using blockchain applications. Ensuring a secured ecosystem attracts investors to invest in digital coins which encourages engagement of ETH applications like DApps, DeFi, and NFTs.

Smart contracts are programs that run on the Blockchain when certain conditions are met. It plays a vital role in transactions of funds as they execute a transaction when two parties agree on the outcome. A smart contract does not involve middlemen during transactions. 

Smart Contract Auditing

Smart contracts are efficient for blockchain technology as they are considered for the construction of blocks in the blockchain. Moreover, smart contracts ensure transparency, trust, and efficiency in transactions. However, security in smart contracts is vulnerable once exploited and since it is immutable, it raises security risks. Therefore, a smart contract is needed here. 

Smart contract auditing entails procedures that are thorough and analyze smart contract codebase and identify vulnerability and insecurity that smart contracts expose. Therefore, the main objective of smart contract auditing is to ensure that the smart contract runs smoothly as it was intended to. In case of any insecurity, the smart contract identifies the issues to the developers, and development is made after. 

Smart auditing is a vital pivot in ensuring that any kind of insecurity in smart contracts is exposed and solved. Therefore, smart contracts audit employees using this technique. It builds trust between users during transactions. Since the smart contract is a third party that validates transactions, it ensures that the two parties can safely use the smart contract. 

Importance of Smart Contract

Smart contracts audit ensures that digital codes stored in a blockchain ledger are flawless and eliminates imperfections of smart contracts. Blockchain technology records all transactions emitted by smart contracts in a ledger. By employing smart contract audits in smart contracts, one ensures that mistakes are prevented. Additionally, the use of smart contract audits ensures that there are no errors during transactions, recognizing errors and eliminating them creates transparency and trust among individuals during transactions.

Smart contracts are responsible for holding valuable tokens and assets; these are digital assets like BTC and ETH. Developers are encouraged to employ smart contract auditing in their applications since it helps prevent huge losses, which creates trust in applications. 

Majorly, it is mainly to protect smart contracts and remove vulnerabilities in smart contracts. 

Smart Contract Auditing Process

Smart contract audit involves analyzing certain risks associated with blockchain. Each process is important in ensuring that a smart contract does not have errors in it. 

The first process is identifying the purpose of the contract and its function. This is important to developers since they will ensure that the contract audit will carry out the intended purpose only. This helps developers to create an audit that focuses on certain aspects of the contract. 

Before employing a smart contract audit, it is important to understand what will the contract audit be carried out, moreover, it ensures that the audit checks if the contract is taking the right task. 

Reviewing the code base is the second process before exercising smart contract units to blockchain applications. Developers should understand the logic, code structure, and dependency either externally or internally before employing the contract to the application. Therefore reviewing the codebase in smart contracts is crucial.

There are three procedures that developers can use in examining smart contracts, they can either do it manually, automatically, or formally. Manual code analysis involves the use of human beings as experts are required to go through smart contracts line by line. 

Automated code analysis requires specialized tools and software that can automatically detect vulnerabilities or errors in smart contracts. Automated code analysis is faster since they conduct the process using robots. The last is formal code analysis which uses mathematical equations to encounter vulnerability in the contract. 

The fourth process is determining the kind of errors the smart contract is facing, the minor and major. The impact of a high-level and low-level error that a smart contract is undergoing is different. We will be looking at the levels of errors that smart contracts undergo.

High level: high-level error can lead to a severe loss of funds or protocol control.

Critical level: this error encounters the functionality of protocols.

Medium level: this error affects the functionality of the application.

Low level: it does not show serious concerns but involves inefficient code supply.

Data level: this poses errors related to coding.

Lastly, it sends the report that has been developed by smart contract audit. This is a document that shows all the errors affecting smart contracts. This ensures that developers and application users are given clear and honest reports. Fortunately, the document presenting these errors and vulnerabilities “may” come with solutions.  


Smart contract auditing therefore ensures that security in blockchain technology is paramount. At this point, smart contract auditing should be necessary for developers. Smart contract auditing will ensure that vulnerabilities and errors are amended and this will ensure that loss of valuable assets is not lost, moreover, transparency and trust will be created between users during transactions.
