Smart Contract Security – Pitfalls and Solutions

As blockchain continues to attain mainstream adoption, security remains one of the top priorities for any blockchain project. Unfortunately, the high volatility and scalability of blockchain technology tends to divert people’s attention away from the issue of the security of assets. 

The release of a smart contract code without necessary testing and auditing jeopardises both the developers and the users. Furthermore, the rise in decentralized finance (DeFi) has increasingly necessitated the need for security audits as it addresses several risks, including that of hacking. 

The continued development and release of untested and unaudited DeFi projects has increased the rate of system hack and cryptocurrency theft. 2021 saw some of the most high profile cryptocurrency thefts so far. In addition, there are growing attacks on DeFi protocols due to several limitations; hence, the need for project developers to adopt strict security standards.

A smart contract audit is needed to identify security and functional issues and improve the security architecture. Auditors are an independent professional team with the technical know-how to analyse smart codes to find limitations and loopholes before releasing them to the public. Smart contract audits are either done manually or automatically.

What do Smart Contract Auditors do?

  • They are professionals with the technical skills to analyse the security of a project and guarantee the safety of the users. 
  • Figure out any errors in the code and how reliable it is for funds transfer. 
  • To validate wallet addresses and spot typographic errors. Detecting bugs and lapses in the system. To protect the platform and its users.

There are currently over 50 smart contract auditing companies, and after thorough research and comparison, we came up with these top 5.
