How to protect your NFTs?

As NFTs gain more exposure and value, this has unfortunately attracted the attention of unscrupulous individuals who would like to seize your assets, by any means possible.

Fortunately, digital assets are incredibly secure at the blockchain level. This means that it is highly unlikely that anyone will lose their assets due to an attack or hack at the blockchain level.

Instead, the vast majority of NFT thefts and losses occur due to asset holders falling victim to one of the growing scam attempts or failing to adequately protect their assets.

Whether you're into digital collectibles or exposed to NFTs , it's important to take the time to understand how to properly protect this rapidly emerging asset class.

This is what you need to know.

Use a hardware wallet

If you are currently storing your NFTs in a custodial wallet solution — don't . Centralized platforms can be hacked, and this has happened multiple times.

Instead, consider purchasing one of the many hardware wallets now available. These are (usually) small physical devices that are used to isolate your cryptocurrency and other digital assets from the Internet and other potentially dangerous situations. These usually require you to manually sign each transaction, preventing someone from remotely stealing your assets. Furthermore, they require the user to take full control of their security, which usually involves backing up and storing their seed phrases /private keys in a secure location.

There are a huge variety of hardware wallets on the market now, including options to suit virtually any budget, and are generally considered an essential accessory for the savvy crypto investor.

Hardware wallets can vary dramatically in their form and function, as well as their overall security, but even the most basic options typically provide much better security than most centralized wallet providers.

With that being said, you should make sure that the wallet you choose supports the blockchains you want to store your NFTs on and also supports the specific NFT token standards, as not all of them will.

Use a different market

If OpenSea's recent blunder has taught us anything, it's that you don't need to be explicitly robbed to lose your NFTs — instead, you could inadvertently end up selling at too low a price.

Depending on the NFT marketplace you choose, you may or may not have access to the controls necessary to adequately protect your NFTs against attacks or errors.

In most cases, NFT markets are non-custodial platforms , which means that you always control your assets, even while they are listed on the market or simply present in your wallet. However, they require users to authorize their smart contracts to interact with their assets, for example, to transfer them to the correct buyer at the time of sale.

If these smart contracts are buggy, this can leave your NFTs vulnerable.

Because of this, it's important to make sure that the marketplace you use is highly secure and reputable. One of the easiest ways to verify this is to look at their public audits, which essentially audit the smart contracts that do not contain bugs or vulnerabilities, and that they are generally safe for the public to use. An NFT audit is a comprehensive code review for verifying the technical and safety of a token, smart contract, and NFT trading platform to mitigate potential cyber threats.

This could be a challenge with newer platforms like LooksRare, which has yet to do a public audit. That said, it's important to balance opportunity against risk, which can make new platforms worth trying if there are significant incentives or opportunities.

Remember, not all NFT markets are the same. Do your research before choosing a platform, especially if it's new or hasn't been tested by large audiences.

Protect yourself against viruses

Computer viruses, while relatively rare, can be devastating to the NFT collector, as they can allow an attacker to exfiltrate data (including your private keys) from your computer in various ways, or even take over your system remotely.

Protecting yourself against viruses is usually a relatively simple task, starting with knowing how to avoid places that might be looking to install virus-laden code on your machine. Some of the usual suspects include copycat websites, sites offering questionable/illegal content, torrents and other P2P file-sharing services, and chat rooms.

In any case, never install a program or open an attachment sent to you from a suspicious source; the vast majority of viruses require you to manually open a file before they can install it.

Beyond this, consider equipping your computer with strong antivirus software and make sure your firewall is turned on. This will help prevent per-vehicle exploits and can alert you to suspicious files that might be on your computer.

MacBooks are generally considered to be less vulnerable to viruses due to their built-in runtime protection, but it's not a foolproof defense: you'll still need to be careful, as macOS viruses remain a potential threat.

Avoid scammers

Unfortunately, the cryptocurrency industry is full of scammers who want nothing more than to part you from your NFTs and other digital assets.

Avoiding these scams can be challenging, especially if you are less experienced, as they almost invariably target less experienced users, because they are often the perfect victims.

But in general, it's possible to avoid the vast majority of scams by adhering to a handful of simple rules.

Always Double Check – When buying an NFT, transferring it, using an NFT marketplace, or doing any other task that requires you to log into a website or service that can access your NFTs, always check that you have the correct URL. Check this information with their social networks to be sure and bookmark the link to avoid falling for a fake link.

Beware of Impersonators – One of the most common ways NFT holders are scammed is by falling victim to an impersonator, i.e. someone who poses as a reputable person, entity or organization, or even a phishing site . Please only use official lines of communication when dealing with transfers or NFT transactions, and always make sure that the person you are talking to is who they say they are.

Unsolicited Messages and Emails – Telegram, Discord, Twitter, and even your email inbox can be prone to spam, scams, and various types of fraud, especially if you were caught in a database leak. If you're receiving unsolicited messages from anyone on any of these (or other) platforms, it's likely a scam. Never give your private keys or recovery phrase to anyone, regardless of their reasons or status, and never authorize smart contracts you are not familiar with.

By following these three key rules, you will be able to avoid the vast majority of risks to your NFTs.

Characteristics of financial statement audits of crypto asset exchange service providers

Positioning of Crypto Assets

At present, the position of "crypto assets" under private law is not necessarily clear, but from the point of view of accounting and auditing, they can be treated as "assets" because they can contribute to the acquisition of funds through trading and liquidation.

In addition, since crypto assets stipulated in the Payment Services Act issued by the Company (including its own affiliated companies) are not subject to the Practical Response Report, the accounting treatment of such crypto assets will be handled separately by the Auditor. It should be noted that it is necessary to consider

 Blockchain Technology

Crypto assets are accepted or withdrawn by users of crypto asset exchange service providers,

Transactions between crypto asset exchanges, transfer of crypto assets between addresses owned by the company, etc.

When doing so, the transaction results will be reflected in the records on the network such as blockchain.

Blockchain, etc. records are information created outside the cryptocurrency exchange service provider, and when smart contract auditing the financial statements of the cryptocurrency exchange service provider, the record of the blockchain, etc. is usually used as audit evidence related to cryptocurrency transaction records or balances. Can be used as audit evidence.

We believe that auditors should obtain blockchain records as audit evidence, and we have a “full node” that reads all blockchain records for each cryptographic asset.

In addition, the “blockchain” described in the audit practice guidelines is based on the assumption that it is a public blockchain.

Audit Scope

When auditors use blockchain records as audit evidence, it is important to understand the technical specifications (consensus algorithms, traceability of transaction records) according to the type of cryptocurrency.

In addition, the purpose of the audit is to express an opinion on the appropriateness of the financial statements prepared by the crypto-asset exchange service provider. Please note that no guarantees are given.

Summary

・Crypto-asset exchange service providers are required to undergo financial statement audits and segregation management audits.

・Smart contract auditors need to deepen their understanding of blockchain before conducting audits.

・The purpose of the audit is to express an opinion on the appropriateness of the financial statements, and not to guarantee the reliability of the blockchain.

How Blockchain Could Revolutionize the Entertainment and Media Industry

Blockchain technology is rapidly changing the landscape of industries worldwide, and entertainment and media are no exceptions. By offering decentralized platforms, tokenization, and enhanced content security, blockchain opens new avenues for creators and consumers alike. Here's why blockchain holds the potential to transform entertainment and media.

Tokenization: Redefining Content Ownership

Tokenization allows creators to transform their work—whether films, music, or art—into digital tokens, representing ownership. These tokens can be sold, traded, or used to unlock special content. For example, an artist could issue limited-edition tokens that offer exclusive behind-the-scenes content or fan interactions. This approach benefits creators by giving them new revenue opportunities while offering fans a unique, personal experience.

Rob Nelson, anchor of Roundtable, predicts that tokenization will become second nature, especially among younger generations. From games to streaming content, tokenized experiences could become mainstream, making entertainment more interactive and dynamic.

Decentralization: Empowering Creators

One of blockchain’s key benefits is decentralization. Platforms built on blockchain allow creators to distribute their content directly to audiences without intermediaries like studios or record labels. Noah Newton, CEO of Moby Media, emphasizes how this democratization gives artists more control over their work. By cutting out middlemen, creators can directly connect with their audience, maintain control of their intellectual property, and ensure fair compensation through automated smart contracts.

Enhanced Security for Intellectual Property

Blockchain technology offers improved security and transparency, which is crucial in protecting intellectual property. Once a piece of content is on the blockchain, it cannot be altered or duplicated, significantly reducing the risks of piracy and unauthorized distribution. This secure environment ensures that creators can share their work confidently without fear of their content being stolen or misused.

Role of Mobiloitte in Blockchain Integration

Mobiloitte, a leading blockchain development company, is at the forefront of integrating blockchain solutions into various industries, including entertainment and media. With its expertise in creating decentralized platforms and secure blockchain networks, Mobiloitte empowers creators to harness blockchain technology for greater control and transparency. Mobiloitte’s solutions enable tokenization, ensuring secure content distribution and intellectual property protection, helping artists and media companies alike to adapt to this technological shift.

Blockchain as a Complementary Technology

Ben Weiss, CEO of CoinFlip, believes that blockchain will integrate seamlessly into everyday life, complementing existing systems rather than replacing them. Just as credit cards operate in the background of online transactions, blockchain could enhance the way content is consumed and distributed without disrupting traditional platforms.

Conclusion

Blockchain has the potential to revolutionize entertainment and media by enabling tokenization, decentralization, and stronger intellectual property protection. As more creators and companies embrace this technology, industries will move towards a more secure, transparent, and democratized model. With companies like Mobiloitte leading the way, blockchain will continue to reshape the entertainment landscape, offering new opportunities for both creators and consumers.

A Comprehensive Guide to Smart Contract Auditing: Best Practices and Strategies

In the rapidly evolving landscape of blockchain technology, smart contracts have emerged as a transformative tool, automating and securing digital contracts without intermediaries. However, their reliance on immutable code leaves them vulnerable to vulnerabilities that can cause significant financial losses and reputational damage. Smart contract auditing plays a crucial role in mitigating these risks by systematically reviewing code for potential flaws and vulnerabilities. This comprehensive guide explores the best practices and strategies involved in smart contract auditing, emphasizing the importance of thorough review processes, secure coding practices and proactive risk management. By understanding and implementing these principles, developers and stakeholders can enhance the security, reliability and trustworthiness of their smart contracts in decentralized applications (dApps) and blockchain ecosystems.

Understanding Smart Contract Audits

What is a Smart Contract Audit?

A smart contract audit is a thorough examination of the code and functionality of a smart contract to identify potential vulnerabilities, bugs or security risks. It aims to ensure that the smart contract behaves as intended, securely manages assets and complies with specified business rules and regulatory requirements. Audits are typically conducted by specialized firms or teams with expertise in blockchain technology and security practices, using both automated tools and manual review processes to assess the contract's codebase.

Key Objectives of Smart Contract Audits

The primary objectives of Smart Contract Audits include:

Security Assurance: To identify and mitigate security vulnerabilities such as reentrancy, overflow errors or logic flaws that could be exploited by malicious actors.

Functional Accuracy: To verify that the smart contract executes its intended operations correctly, adhering to specified business rules and ensuring accurate handling of transactions and data.

Risk Mitigation: To reduce the risk of financial loss or disruption by addressing potential weaknesses before deployment, thereby enhancing trust among users and stakeholders.

Compliance and Standards: To ensure that the smart contract complies with industry best practices, regulatory requirements and any applicable standards for security and reliability in blockchain applications.

Differences Between Code Audits and Formal Verification

While both are essential components of smart contract validation, code audits and formal verification differ in their methodologies and scope:

Code Audits: Involve a comprehensive review of the smart contract's source code to identify potential vulnerabilities and ensure adherence to best practices. Auditors typically rely on automated tools and manual inspection to detect bugs or security issues.

Formal Verification: Involves mathematically proving the correctness of a smart contract's code against specified properties or requirements. This rigorous process uses formal methods to verify that the contract behaves as intended under all possible conditions, offering a higher level of assurance but often requiring specialized expertise and computational resources.

By understanding these distinctions and integrating both approaches where appropriate, developers and stakeholders can effectively enhance the security, reliability and functionality of their smart contracts in blockchain applications.

Common Smart Contract Vulnerabilities

Overview of Typical Vulnerabilities:

Smart contracts, despite their promise of security and automation, are susceptible to several common vulnerabilities that can be exploited by malicious actors. Some of the most prevalent vulnerabilities include:

Reentrancy: This vulnerability occurs when a contract calls an external contract before completing its own state changes. If not properly managed, reentrancy can allow an attacker to repeatedly call back into the contract, potentially manipulating its state and causing unexpected behavior.

Integer Overflow and Underflow: Smart contracts often handle numeric values for calculations and storage. Integer overflow happens when a number exceeds its maximum value and wraps around, while underflow occurs when a number becomes negative due to subtraction beyond zero. These conditions can lead to unintended consequences, such as incorrect calculations or unexpected behavior.

Unchecked External Calls: Smart contracts may interact with external contracts or addresses. If these interactions are not properly validated and checked for potential malicious behavior, they can introduce security vulnerabilities, such as unauthorized transfers of assets or manipulation of contract state.

Logic and Design Flaws: These vulnerabilities arise from errors in the logic or design of the smart contract. They can include incorrect assumptions about user behavior, inadequate access control mechanisms or failure to handle edge cases properly, potentially leading to unintended consequences or exploitation.

Real-World Examples of Smart Contract Failures Due to Vulnerabilities:

Several notable incidents have highlighted the consequences of smart contract vulnerabilities:

The DAO Hack (2016): Exploited a reentrancy vulnerability to drain approximately $50 million worth of Ether from The DAO, a decentralized autonomous organization on the Ethereum blockchain. This incident led to a hard fork in Ethereum to recover the funds, highlighting the impact of smart contract vulnerabilities on blockchain communities.

Parity Wallet Bug (2017): A vulnerability in the Parity multi-signature wallet contract resulted in the freezing of hundreds of millions of dollars' worth of Ether. This bug was due to a flaw in the contract's initialization code, demonstrating the critical importance of rigorous auditing and testing in smart contract development.

Integer Overflow Bugs: Various smart contracts have been vulnerable to integer overflow and underflow bugs, leading to unexpected behavior and potential loss of funds. These incidents underscore the need for robust testing and validation of numeric operations in smart contracts.

By understanding these common vulnerabilities and learning from past incidents, developers and auditors can take proactive measures to mitigate risks and enhance the security and resilience of smart contracts in blockchain ecosystems.

Best Practices for Smart Contract Development

Secure Coding Principles for Smart Contracts:

Implementing secure coding practices is crucial to mitigate vulnerabilities and enhance the resilience of smart contracts. Key principles include:

Input Validation: Validate and sanitize all inputs to prevent unexpected data manipulation or exploitation.

Minimize Complexity: Keep smart contracts simple and minimize the number of operations to reduce the risk of introducing bugs or vulnerabilities.

Avoid External Calls During State Changes: Limit or eliminate external calls during critical state changes to prevent reentrancy attacks.

Use Safe Math Libraries: Utilize libraries that provide safe arithmetic operations to prevent integer overflow and underflow vulnerabilities.

Access Control: Implement access control mechanisms to restrict functions and data access to authorized entities only.

Use of Established Libraries and Frameworks:

Utilizing well-established libraries and frameworks can significantly enhance the security and reliability of smart contracts. Benefits include:

Security Audited Code: Libraries and frameworks that have undergone rigorous security audits are less likely to contain vulnerabilities.

Community Support: Established libraries often have a large community of developers who contribute to bug fixes, improvements and security enhancements.

Code Reusability: Reusing trusted code reduces the likelihood of introducing new vulnerabilities and accelerates development timelines.

Importance of Documentation and Comments:

Comprehensive documentation and well-commented code are essential for maintaining and securing smart contracts. Reasons include:

Understanding Contract Functionality: Clear documentation helps developers and auditors understand the intended behavior and logic of the smart contract, reducing the risk of misinterpretation.

Facilitating Audits: Detailed comments and documentation assist auditors in identifying potential vulnerabilities or areas of concern during the audit process.

Enhancing Code Maintenance: Good documentation simplifies future updates and modifications to the smart contract, ensuring continuity and minimizing errors.

By adhering to these best practices, developers can significantly improve the security, reliability and maintainability of smart contracts, contributing to a safer and more robust blockchain ecosystem.

Preparing for a Smart Contract Audit

Initial Code Review and Testing Phases:

Before engaging an external audit, it’s essential to conduct thorough internal reviews and testing:

Internal Code Review: Perform a meticulous internal review of the smart contract code to identify and resolve obvious errors and vulnerabilities. Involve multiple team members to ensure diverse perspectives and catch issues that a single developer might miss.

Automated Testing: Use automated testing frameworks to conduct unit tests, integration tests and end-to-end tests. Ensure that the tests cover all possible scenarios, including edge cases, to verify the contract behaves as expected.

Manual Testing: Complement automated tests with manual testing to explore unusual or unexpected interactions and user behaviors that automated tests might not cover.

Simulation and Mock Environments: Use simulation tools and mock environments to test the contract in a controlled setting that mimics the live blockchain environment. This helps to identify potential issues related to transaction ordering, gas consumption and network interactions.

Setting Audit Goals and Expectations:

Clearly defining the scope and objectives of the audit is crucial for a successful engagement:

Define Scope: Identify which parts of the codebase need to be audited. This could include specific smart contracts, libraries and integrations with external systems.

Set Security Priorities: Establish key security priorities, such as preventing financial loss, ensuring data integrity and maintaining user trust. This helps auditors focus on the most critical areas.

Communicate Expectations: Provide auditors with detailed information about the contract’s intended functionality, business logic and any known risks or concerns. Clear communication ensures that the auditors understand the contract’s purpose and the specific aspects to scrutinize.

Timeline and Deliverables: Agree on a realistic timeline for the audit process and define the expected deliverables, such as detailed reports, risk assessments and remediation recommendations.

Choosing an Audit Firm or Team:

Selecting the right audit firm or team is crucial for a thorough and effective audit:

Experience and Reputation: Choose a firm or team with a proven track record in smart contract auditing. Look for auditors with experience in your specific blockchain platform and technology stack.

Independent and Unbiased: Ensure that the audit firm is independent and has no conflicts of interest that might compromise the integrity of the audit.

Technical Expertise: Assess the technical expertise of the audit team. They should have deep knowledge of smart contract development, blockchain security and the latest vulnerabilities and attack vectors.

References and Case Studies: Request references and review case studies of previous audits to gauge the quality and thoroughness of the firm’s work.

Communication and Collaboration: Choose auditors who are communicative and willing to work collaboratively with your development team. Effective communication is essential for addressing issues and implementing recommendations promptly.

By carefully preparing for the audit, setting clear goals and choosing the right auditors, you can significantly enhance the security and reliability of your smart contracts, building trust with users and stakeholders.

Conducting a Smart Contract Audit

Steps Involved in the Audit Process:

Conducting a thorough smart contract audit involves several key steps to ensure comprehensive review and identification of potential vulnerabilities:

Initial Assessment: Review project documentation, including specifications and design documents, to understand the contract's intended functionality and security requirements.

Code Review: Perform a detailed review of the smart contract codebase, examining each line for vulnerabilities such as reentrancy, integer overflow, logic flaws and unchecked external calls.

Hidden risks in Smart Contracts: How to ensure a secure implementation

Smart contracts are a powerful tool in the world of cryptocurrencies and blockchain technology. They are autonomous, irrevocable, and run automatically when certain conditions are met, making them an ideal solution for a wide variety of applications, from automating business processes to creating new forms of crowdfunding. However, as the popularity of smart contracts increases, so do the risks associated with their implementation. From typos to security flaws, the hidden risks in smart contracts can be devastating. It is essential that developers understand and address these risks to ensure the security of their deployments and protect users from potential attacks or bugs.

What is a Smart Contract?

A Smart Contract is a type of code that allows the verification and automatic execution of an agreement . This concept represents a significant change in the business world, since Smart Contracts work on blockchain technology and do not require human intervention to verify and enforce the agreed conditions.

In the case of loan contracts, for example, Smart Contracts allow the lender to automatically close access to money if the borrower does not comply with the agreed payments or interest. In addition, Smart Contracts are also useful in data verification and for the implementation of clauses in insurance contracts, thus reducing the chances of disputes.

It is true, the creation of an efficient Smart Contract is a major challenge. The ability to express value, transparency and immutability are three of the most important attributes of a Smart Contract, but they also make them more vulnerable to cyberattacks.

Despite the fact that there is not always a malicious intent behind these attacks, errors in the programming of Smart Contracts have led to capital collapses and significant losses for companies. Therefore, it is essential to be aware of the most common vulnerabilities that can arise in Smart Contracts.

But now we are going to get into the matter with the five most common problems in the security of Smart Contracts and how to avoid their possible risks and consequences.

1. The Arithmetic Error of Whole Numbers

Using integers to represent values ​​in smart contracts is common practice due to the lack of support for floating point numbers. Often, reducing the value to a smaller unit is required to achieve adequate precision. Most tokens support up to 18 decimal places, further improving accuracy.

However, developers should be aware of the potential for integer overflow. Just like car mileage, integers in a computer also have a maximum value, and once that value is reached, they return to their minimum value. Similarly, subtracting 4 from 3 in an unsigned integer will result in an overflow and a very large value. To avoid this problem, developers can use safe math libraries.

Also, developers should be aware of the inaccuracy that can occur when integer arithmetic is executed incorrectly. The order of operations is crucial, especially when calculating percentages. For example, to find 25% of 80, it is common to divide by 100 and then multiply by 25. However, wrong division can result in rounding error. For example, calculating 80/100 * 25 using only whole numbers will result in 0.

This error, although it seems simple, is common among developers. Therefore, it is important to pay attention to detail and be aware of possible errors in integer arithmetic in smart contracts.

2. Vulnerabilities in the Block Gas Limit

Ethereum keeps block sizes in check through the block gas limit. This implies that the amount of gas that transactions within a block can consume is limited. If a transaction consumes too much gas, it will not be included in the block and therefore will not execute.

This can lead to a common vulnerability: when data is stored in variable-size arrays and accessed through a loop, the transaction can time out quickly and roll back if there are too many items in the array. This issue usually occurs in production, but not during testing, because the test dataset is typically smaller than the production dataset.

This vulnerability is dangerous because contracts related to it usually pass unit tests and work well with a small number of users. But as the project grows and the data set gets larger, these contracts can fail. In this case, there may be an irrecoverable loss of funds, especially in the case of recurring payments.

3. Front Running

Before continuing, I prefer to make a short introduction for those who are not familiar with the term.

To understand what front running is, it is essential to know how to make profits ahead of the execution of a trade. Traditionally, front running is accomplished by acquiring inside information about events that may affect the price of shares, commodities, or other financial instruments. However, in the cryptocurrency markets, order flow is the key element.

Now yes, we continue with regard to security...

Analysis of the order flow and the size of the blocks can provide an idea of ​​the direction in which the price is moving. Therefore, front running in the cryptocurrency realm involves anticipating the correct order in the order flow.

Unconfirmed transactions are visible in the memory pool before miners add them to a block, allowing interested merchants to monitor their content and advance the transaction by paying higher fees. This process can be easily automated and is common in decentralized finance applications.

Frontrunning refers to taking positions on unconfirmed transactions, and is a result of transparency in the blockchain.

Fixing this issue often requires a major refactoring or redesign.

4. The lack of control in the parameters and preconditional controls

In programming, a common mistake is forgetting to check the parameters of a function or not performing the necessary checks to ensure the validity of a particular operation. This can include address parameters not being checked against address zero, or an unauthenticated user not having enough tokens to perform a specific transaction. The access check is also important, as only certain types of users should be allowed to call a given function, but sometimes this check is skipped.

These errors are often the result of an oversight in the design process. Therefore, it is useful to have a written record of the functions, including the parameters, the preconditions, and the operations to be performed. Following stable design patterns, such as Check-Effect-Interaction, can also help prevent these types of vulnerabilities.

5. Logical bugs (or not so much…)

The most common problem in smart contracts is an error in their own logic. These errors can be caused by small typos or misinterpretations of specifications, which can have a large security impact. Although programming errors specific to smart contracts are important, logic errors are inherent in the programming itself. It is essential to pay attention to the logic and make sure that the specifications are understood before you start writing the code.

In conclusion…

In short, the security of smart contracts is essential to guarantee the integrity and efficiency of decentralized applications. Common bugs include lack of privacy, reentrancy vulnerabilities, front running, and missing parameters or precondition checks. Also, logic errors can be caused by simple typos or spec misunderstandings. To ensure security, it is necessary to follow good programming and design practices, have a solid understanding of blockchain technology and smart contracts, and perform extensive testing and peer review before implementation. The security of smart contracts is a critical aspect in the development of decentralized applications and must be properly addressed.

What is a Smart Contract Audit?

Assume you have incorporated your business and prepared the essential paperwork. Auditing firms evaluate the quality of the documentation's preparation and the reliability of your organization before issuing a reliable result. In the realm of cryptocurrency, a similar model is used. For its project, each business builds a virtual infrastructure. Also known as a smart contract. In actuality, this is a program code that forms the foundation of the project's basic concept. It may be an exchange, exchanger, and bridge for cryptocurrencies, aggregator, investment fund, and many more things.

The application of smart contracts in the blockchain ecosystem allows for the total eradication of fraud and contract breaches between parties to various processes. Existing algorithms are sufficiently reliable to eliminate the need for middlemen and make every transaction as transparent as possible.

Despite its dependability, smart contracts are frequently breached, which can lead to losses in money or reputation. Two things can cause issues: flaws in the code and human mistake. Theft of monies from participants in cryptocurrency initiatives occurs often in the business. 

Why does this occur while smart contracts are one of the present day's most secure ways to manage money? Hackers, for all their excellence, are also on guard. As contracts get more intricate, they become more inventive. "Blockchain is secure, but blockchain applications are not necessarily secure," as the phrase goes. Smart contract audits, which have lately become more and more common, were created to mitigate this and prevent situations like these.

The contract code is examined by auditing firms, who subsequently compile a report and deliver it to the project. Projects can then release the report to the public. Since the investor's choice to deposit money is dependent on audits of the project's smart contract, audits are most common in the decentralised finance space.

The audit includes four stages:

Initial human and automatic contact analysis

If a defect is discovered, it is immediately reported to the developers for correction

Developers are working to solve the bug

The auditors recheck the code; if nothing is discovered, they provide a report.

Even the smallest programming error might result in substantial costs. As a result, the auditors repeatedly mimic hacker attempts and make an independent attempt to compromise the smart contract. A typical smart contract audit comprises testing and looking for significant faults, automated analysis using specialised tools, and study of the specification and related documentation, which outlines the project architecture.

Manual analysis is, of course, the most important step. You may identify how the code relates to the defined functionality through this process.

What Problems are fixed by a Smart Contract Audit?

Due to their decentralised structure and lack of a regulating party, decentralised apps, whether they be DeFi, blockchain projects, or smart contracts, have drawbacks that allow them to freeze a portion of user or developer cash inside the blockchain without the prospect of recovery.

This is comparable to sending a financial transaction to the incorrect recipients. However, if it's a bank, you can be confident that you can fix the problem by phoning the bank. Banks also guarantee the security of their software, reducing the likelihood of losing personal funds.

Such a central regulator does not exist in the context of blockchain applications and smart contracts. As a result, the contract that was published on the blockchain network begins to operate on its own. Therefore, it is crucial to understand that the contract code is flawless and won't let your money vanish into thin air. What is checked during the audit is this. Additionally, by including an action code that will enable them to steal users' cash outside of the algorithm, the contract's designers may have been dishonest in their design.

An audit assists in identifying both important and less serious flaws in smart contracts. For instance, there are issues with integer arithmetic, a block gas limit vulnerability when an array overflows, missing arguments or preconditions (caused by negligent development), probable front-running (overtaking an unconfirmed transaction), and a huge number of logical errors.

All of these can only be found if the auditor has a thorough grasp of the codebase's architecture, as well as the project's planned functionality and the contract specification. According to experts, this is the reason why auditing smart contracts demands time, money, and the involvement of highly educated professionals.

Our staff has the ideal mix of expertise and experience when it comes to the realm of cryptocurrencies and blockchain technology.
