Blockchain Security Audits

What is a Smart Contract Security Audit?

The audit of A smart contract analyzes the source code to see if it follows the predetermined conditions and behaves as the developer intends. Auditing a smart contract aims to discover possible errors and security vulnerabilities in the code and recommend improvements and ways to fix them.

Smart contract audits are widespread in the Decentralized Finance (DeFi) space. While most people understand the importance of audits for cybersecurity, few care to dive into the lines of code. However, we suggest that if you’re considering investing in a project, it is better to look into its smart contract code review and then decide.

A smart contract audit involves bringing in a wide range of potential scenarios and running endless, exhaustive tests with a lot of third-party applications to find any bugs. After the initial testing is over, the auditors produce a report for the contract-building team to review. The team gets the chance to address any problems before the audit is over. This offers them the opportunity to add any revisions to the final report.

To grant an auditing firm a contract, a team must first agree on the audit’s parameters and scope. Before testing can begin, the audit’s criteria must first be set. Auditors can start testing individual smart contract components after defining the audit’s goals to make sure each feature works as it should. Following this, auditors test more extensive portions of the contract and examine the code using automated bug selection methods. Before the final report is released, the team receives the results of a manual code review for corrections.


Common Vulnerabilities In Smart Contracts + Measures To Avoid Them

Some of the common vulnerabilities in smart contracts include:

  • Storage of unencrypted files on the blockchain

    Storing confidential information on the blockchain can cause a major threat to security as blockchains are accessible to anyone thus putting your entire system at risk. Avoid this issue by making sure to never save anything confidential on the blockchain without first encrypting it.

  • DoS attacks

    Denial of service attacks can be done through denying authentication or services or by overloading ports with requests. Add failsafe into the smart contract and ensure that all nodes have sufficient storage and processing power.

  • Smart contracts with no upgrade options

    Smart contracts by definition are not modifiable but rather self-destructed. But this poses an issue if some mistakes are made. Avoid the issue of making a bugged smart contract by making sure they can be upgraded using proxies or pausable functions.

  • Function default

    Functions are visible by default, therefore, meaning everyone can execute them. Always make sure that function visibility is well defined and stated clearly to avoid any trouble.

Security for a Decentralized World

Smart Contract Audits (Ethereum, Hyperledger, EOS, Polygon, Solana, Tezos, Binance Smart Chain) by a reputable company are an essential part of any smart contract development. While the rise of blockchain presents a unique opportunity to create smart contracts for digital assets, such as token. Smart Contract applications come with unique security concerns that have historically led to millions of USD in losses (The DAO or Parity Freeze).

To mitigate these risks, it is necessary to conduct Smart Contract Security Audits, also to provide transparency to the investors and community.
