Smart Contract Audit Services

The importance of smart contracts and the Defi platform is becoming more apparent as blockchain technology adoption increases across the globe's many spheres. Applications such as decentralised finance and NFTs use intelligent contracts as their underlying blocks. They are the self-executing code that determines all terms and conditions for the application.

Due to the immutable nature of blockchain technology, it is impossible to modify the code once it has been deployed. Without good audits, smart contracts could be placed without consent. This could result in undesirable situations such as gas leakage, differences in contract performance, and other problems.

A blockchain application development company offers security services that expose the vulnerabilities of smart contracts. It allows organisations to avoid hackers, security breaches, or other cyber threats, thereby ensuring financial security.


Smart contracts are a vital component of blockchain technology. Smart contracts are used in a wide range of transactions and applications. Smart contracts are used in every aspect of our everyday lives, from finance and IoT to supply chains and music.

Think about how transparent intelligent contract implementation is for all blockchain users. There are situations where security flaws can also be visible and can be exploited or abused by hackers to harm an organization's intelligent contracts further. These attacks could lead to a loss of revenue, data exposure, and other problems.

To prevent these attacks, it is crucial to learn how intelligent contract security works, its proper implementation, and other aspects of protecting an innovative contract-based platform from cyberattacks and hacking attempts.

So, let's dig in.

What is the secret to it?

A smart contract, a type of Ethereum account, runs on the blockchain-based Ethereum platform. When pre-set terms are met, smart contracts are executed automatically. This makes it possible to execute and deliver an agreement immediately without intermediary services. An Ethereum account is a collection of ether (ETH) with a balance. Users' accounts can communicate with a smart contract by submitting a transaction. This transaction executes a predefined function that gives access to data in smart contracts.

Nick Szabo, a computer scientist, lawyer, and cryptographer, originally defined intelligent contracts in 1996 as "Building Blocks for Digital Markets." He says smart contracts are "smarter" than their paper-based, inanimate ancestors. "Artificial intelligence is not implied."

Nick refers to intelligent contracts as "digital vending devices." A vending machine that works through a contract is executed when a person pays and receives the product.

What are the various types of smart contracts?

Smart contracts can be created and deployed via a network using programming languages like Solidity or Vyper. You will also need enough Ethereum to deploy the contract (using gas fees).

Smart contracts can be divided into four types based on their use by programmers to build applications.

These are the types:

  • Decentralized autonomous organizations (DAOs), which have rules that are controlled and established by members of an organization and not affected by external entities, are called decentralized autonomous organizations.
  • Smart legal contracts (also known as "legally enforceable intelligent contracts") require strict legal resources and are legally binding. A computer programme executes all the contractual agreements automatically.
  • Applied Logic contracts are built on a distributed network that does not rely on a single server. This allows intelligent contracts to be combined with the user interface.
  • Distributed Applications (DApps) are code-based applications that work in sync with or in combination with smart contracts.
Common vulnerabilities in smart contracts and how to avoid them

Some common weaknesses in smart contracts are:

  • Blockchain storage of unencrypted files
  • Security can be compromised by storing confidential information on the blockchain.

    This issue can be avoided by encrypting all data on the blockchain before it is saved.

  • DoS attacks
  • You can use denial-of-service attacks by denying authentication or services or overloading ports with requests. Include a failsafe in the smart contract to ensure that all nodes have enough storage and processing power.

  • Smart contracts that do not require any upgrades
  • Smart contracts are, by definition, not adjustable but self-destructive. This can be problematic if mistakes are made. Avoid the problem of bugged smart contracts by ensuring that they can be upgraded with proxies and pausable functions.

  • Function default

By default, functions are visible so that everyone can execute them.

To avoid any problems, make sure you clearly define and state the function's visibility.

How can smart contracts be secured?

Organizations that use smart contract technology can take advantage of its security features. It acts as a mediator between the parties to a transaction.

There have been numerous instances when platforms that run on smart contracts were compromised by poor software development and inadequate security measures.

Best Practices for Secure Coding in Smart Contracts

Different programming languages are used to create smart contracts, such as Solidity and Vyper, Java, Go, and Go. It is crucial to use all publicly available resources to code secure smart contracts. You can use these best practices during intelligent contract design, implementation, and deployment.

Slither printers can be used to create architectural and schema diagrams.

Make sure to document your code using the keeps Natspec format (for Solidity) and keep as much code off-chain as possible.

Create small, meaningful functions and divide the logic using multiple contracts or grouping functions.

You can try to reduce the inheritance tree. To check the hierarchy, use Slither's inheritance printer.

Slither, Echidna, and Manticore allow you to write customer checks and property descriptions.

Cryptography can be used to secure the wallets of your most privileged users.

Pentesting and auditing of smart contracts.

Hackers can exploit security flaws and loopholes in smart contracts, even if they are secure and bug-free. They could compromise smart contracts or entire blockchain platforms and steal millions of dollars' worth of cryptocurrency.

This problem can be solved by the periodic penetration of smart contract audit services. These vulnerabilities can be found through security audits and pen testing. This allows you to correct them before hackers attempt to hack your platform.

PerfectionGeeks Technologies has helped numerous blockchain platforms with security audits, penetration testing, and other services. The pen-testing tool Astra Pentest, which is simple to use, provides a central management dashboard for security and management teams. Our certified auditors are highly trained and ensure no security hole or vulnerability is overlooked.

Adhere to the blockchain security checklist

Use well-researched, practical checklists to ensure the security of your blockchain-based apps. A good checklist for blockchain security includes the following:

  • Mandate multifactor authentication.
  • Security incident and event management (SIEM) can be leveraged.
  • Policies that determine the level of access required for the proper purpose.
  • To access blockchain solutions, IAM must be enforced.

These are only a few of the best practices. Read them all to get the most out of blockchain engineers' security.

Automated vulnerability scanners

An automated security scanner is a tool that can assist you in a security analysis of smart contracts. This scanner can identify security flaws in your code and help you avoid them. This open-source security scanner can be used for Ethereum smart contracts and is supported by the Ethereum Foundation. It's called security.

PerfectionGeeks Technologies offers a professional smart contract security audit

Many IT teams may need help understanding the complex structure of smart contracts and blockchains during security audits of intelligent contracts. Insufficient knowledge and limited resources can cause IT, teams, to get stuck in the Smart Contract Audit Solutions process. This could lead to wasted time and costly resources.

It is best to seek professional assistance for smart contract audits from certified security experts who can do the job quickly so that you can focus on your business.

PerfectionGeeks Technologies can help you with your blockchain platform or intelligent contract audit without hassle. PerfectionGeeks Technologies' award-winning team provides the most innovative contract security solutions.
