what you should take into account to protect your digital assets
Everyone is talking about cryptocurrencies. Like it or not, we are going to have to live with them in the coming years . We are not required to use them, at this time. But knowing about cryptosecurity, cryptocurrencies and/or crypto assets will help us understand the world of cryptocurrencies . Not only that, it will also help us to know a little more about cybersecurity.
And it is that cryptocurrencies are based on cryptography , encryption, to make secure transactions, create more virtual currencies and verify those transfers. Based in turn on blockchain technology , translated as chain of blocks, an encrypted and decentralized database records who owns such a quantity of cryptocurrencies. While that user is anonymous. We will have access to these cryptocurrencies with a code or key that we will keep in a cryptocurrency portfolio or crypto wallet .
But even if everything is very safe, in cybersecurity there is always the possibility of human error , carelessness or a vulnerability that someone will take advantage of to get hold of such a precious commodity such as cryptocurrencies. It is not something that happens often, but for our part we can take several precautions to protect our crypto assets or digital assets.
The importance of a good password
Cryptocurrencies are based on encryption technology that, to date, is unbreakable. Crypto security advocates say that Bitcoin has not been hacked so far since it was created in 2008. So, in principle, cryptocurrencies are safe. Where is the weak part of the chain? In the user and in the platform that guards the digital assets.
So the first tip that is usually given in cybersecurity is to have a good password . That is, one that is difficult to guess. It is usually recommended to mix letters, numbers, uppercase and lowercase . There are no foolproof passwords, but the more complex it is, the more it will cost to figure it out. We can help ourselves with password generators. Password managers often come with one. The most popular password managers are 1Password, LastPass, Dashlane , and Bitwarden .
In relation to the password, try to always activate the verification in two steps . Many current Internet services require turning it on by default. This is a second layer of security for when you log into a web page or mobile application. It is not enough to enter the password. You will have to confirm it in a second step. More security, more difficult for cybercriminals.
And of course. No sharing passwords or credentials . They are private, so it is convenient to keep them safe and use them only us. If we want to share them, it is better to exchange the cryptocurrencies instead of sharing the virtual wallet at the risk of losing its content if it falls into the wrong hands.
Cryptocurrencies and phishing scams
Many of us call it social engineering . What some media attribute to the cybercriminal's computer expertise is actually something as old as deception. There has always been someone who has made a living deceiving others. And with the Internet, telephones and emails, this is still the case.
Fraudulent emails, WhatsApp or Bizum messages, phone calls... There are many methods. Today they are known as phishing or identity theft . Someone pretends to be someone who is not for you to provide information. They can ask you for your ID, your bank account, your credit card or your password.
Focusing on the world of cryptocurrencies and cryptosecurity, messages are often sent to potential victims with links to fake web pages . It looks like a legal cryptocurrency platform, so if you fall for it, just enter your details like you always do. The downside is that this data ends up with someone who wants to steal your cryptocurrency wallet .
If you access your virtual wallet or exchange or exchange platforms from the browser, access from the official page. It is usually encrypted by default , that is, you will see a padlock in the browser bar. Save those links in your browser to always enter from there and not from a link you receive in a message.
Another important detail of cryptosecurity is that of the addresses to send cryptocurrencies . Try not to be wrong. Copy and paste the address instead of doing it by hand or you will send money to the wrong address at the risk of not getting it back. Addresses can typically be copied to the clipboard or even embed a QR code for easy sharing.
Attacks on cryptocurrency platforms
The above tips are directed at users and holders of cryptocurrencies. But it is not always within our reach to defend ourselves against cybercriminals. Cybersecurity also affects those who custodian our cryptocurrencies. That is, the exchange or exchange platforms.
It is not often, but from time to time we read that someone has lost their cryptocurrencies because a platform has been attacked by cybercriminals . Sometimes they can be recovered, but this is not always the case. And that the owner took security measures.
One of the advantages of owning cryptocurrencies is that you can guard them yourself. In other words, by default we can have a cryptocurrency portfolio whose content is monitored and stored by a platform such as Binance, Coinbase , Crypto and many more. But we can also choose to have that portfolio at our disposal . The risk is that if we lose the keys we will not have access to the cryptocurrencies. The good thing is that if the exchange platform is attacked we will avoid losing our cryptos.
More cybersecurity tips for day to day
We have seen the three most important cryptosecurity tips to protect our digital assets. But in cybersecurity there are many dangers and many precautions to take. For example, we must avoid connecting to public WiFi networks if we are going to make purchases online or manage our cryptocurrencies. It is not frequent, but that WiFi network may not be secure. Better to do these efforts from home.

Best practices for storing crypto securely
Custodial wallets are an easy and secure way to store crypto as they are managed by a third party. They offer convenience, but the user does not have access to their private keys and therefore trusts the platform for their security.
Cold wallets provide the highest level of security for storing crypto as users have control over their private keys, but setting up and using these wallets can be difficult for non-techies.
Active wallets are more convenient than cold wallets, but offer less security since users do not have access to their private keys. They are perfect for day-to-day transactions but not recommended for large amounts of money.
Whenever you choose a storage option, be sure to keep your passwords secure and research the provider before making any deposits.
Cryptocurrency investors should be aware of the different options for safely storing cryptocurrency in order to protect their investments. Doing that comes with unique security protocols, like keeping private keys safe. There are three main crypto storage options available: custodial wallets, cold (offline) wallets, and active (online) wallets. Each option has various pros and cons depending on your needs, so it's important to understand them before deciding which one is best for you. This article will help you make that decision.
Custody Portfolios
A custodial wallet is a type of crypto wallet that is managed by another person or company. It's easy to use and you don't have to worry about losing it, as long as you can access your account. The good thing about custodial wallets is that they require the least amount of work on your part and are easy to access if you want to trade your assets. But the downside is that a third party controls your crypto, which means you trust them for security rather than yourself.
The process of storing cryptocurrency in a custodial wallet is relatively simple. All you have to do is create an account with a platform and deposit your crypto. Once it is deposited, the platform will store your crypto securely. You can check your balance at any time and use the services of the platform to trade or withdraw funds. If you choose this type of wallet to store your assets, we recommend that you choose platforms with strong security tron; like Binance .
cold wallets
Cold (offline) wallets are a popular storage option among cryptocurrency investors who are looking to strictly protect their funds from cyber threats and be in full control of their assets. These wallets store your private keys and public addresses on an encrypted piece of hardware, usually a physical device like a USB drive. They are considered the most secure way to hold cryptocurrencies as they keep them offline and away from malicious actors.
The process of storing cryptocurrency in a cold wallet is much more complicated than that of custodial wallets, as it requires you to create and back up your wallet before you can start depositing funds. This means that you will have access to the private keys that give you full control over your assets. These private keys should be kept securely in one place, preferably only you know. The downside to cold wallets is that they can be difficult to use, especially for those who aren't tech-savvy, but you can always ask for help or search for tutorials on YouTube.
hot wallets
Hot (online) wallets are another popular option for storing cryptocurrency. These digital wallets are located on secure servers that can be accessed through a web browser or special mobile applications. The convenience of hot wallets makes them the perfect choice for everyday transactions, as they allow users to store and access their funds quickly and easily.
The process of setting up and using a hot wallet is very similar to that of custodial wallets. All you have to do is create an account on a platform, deposit your funds, and then use the platform to buy or sell cryptocurrency. The main difference between these two types of wallets is that you do not have access to your private keys with an active wallet, so it is not considered as secure as cold or custodial wallets.
Alternatives to software wallets
Like the hot and cold wallets described above, software wallets can still pose a threat if private keys are exported or keywords are stored insecurely. There has been concern that some apps or even iOS will back up your private keys to iCloud because there have been reports of users restoring a phone from iCloud and being presented with access to their wallets.
An alternative to a software wallet is to use a hardware wallet, an offline physical hardware device. This makes you immune to PC viruses, cyber attacks and means that private keys are never stored on a device that could succumb to vulnerable software.
If you're not looking to buy such dedicated hardware, you can still create a secure offline wallet using your own bootable USB or live CD. The wallet still needs to be kept offline, and the only real threat to you would be if you lost the USB.
Best practices for security
Spread cryptocurrency holdings across multiple portfolios to diversify risk
Use two-factor authentication with software wallets (preferably biometric like one)
Regular backups of a wallet in case of computer failure or human error
Do not store backups online and/or unencrypted
Generate unique addresses for each transaction
Require 2 or more signatures to spend funds
Key storage in different places
Conclusion
When it comes to choosing a crypto storage option, you need to consider your needs and the amount of risk you're willing to take. Active wallets are great for small amounts of money that you plan to use regularly, but are not recommended for large amounts of crypto assets as they are more prone to attacks. Cold wallets offer the highest level of security, but require you to keep your private keys safe and secure. Custodial wallets may be the right choice if you need easy access to your funds or don't want to worry about managing them yourself. Whichever wallet you choose, be sure to keep your passwords safe and research the provider before making any deposits.

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. -
5 threats to Ethereum smart contracts
Smart contracts can have flaws that seriously affect their effectiveness.
Main threats facing Ethereum smart contracts and other blockchains. In addition, he provided a brief summary on how to prevent and deal with them, during his presentation at the Ethereum Rio 2022 conference, yesterday, March 15.
The proliferation of decentralized finance (DeFi) protocols has led to these platforms being targeted by numerous hackers in the past two years. As Tarditi explained in his speech, more than USD 1.3 billion was lost as a result of these computer thefts in 2021 .Among the most important cases of DeFi hacks last year, the specialist cited what happened with Uranium , with losses of USD 50 million; Compound, with a negative balance of USD 90 million in misdistributed rewards in the month of October; and bZx, which lost $55 million in November to an email phishing attack and also suffered repeated attacks in 2020 .
Also in 2022 these events continue to happen, as happened to the Qubit, Wormhole and meter.io protocols. CriptoNoticias has reported on these cases quite frequently since mid-2020.
Regarding this topic, the speaker explained that his company has carried out more than 1,400 audits of smart contracts in the last six months, which produced a total of 16,400 problems, 5,300 of them of a critical nature for the security of the protocol .
The main risks for smart contracts on Ethereum
To dig deeper into this question, David Tarditi listed five vulnerabilities that decentralized finance protocols can face. He also told how to enhance security to reduce the risk of suffering from them.- Centralization
By far, it is the main problem found by Tarditi and his team in audited smart contracts. They found no less than 3,000 cases of centralization in 1,400 audits . That is, more than 2 errors or failures by contract.
Centralization in smart contracts in Ethereum occurs when there is an "owner" or centralized entity that can alter balances, distribute tokens, make fund withdrawals, update the contract or modify its parameters at will, among other sensitive functions, explained the speaker. .
Precisely, the essence of these contracts and DeFi , as its name indicates, is to eliminate the middleman . In other words, the operation of the protocol must be automated and governed by the code itself, with no possibility for the developer company or any other person to modify it according to their convenience and criteria. This centralization can be even more dangerous when a hacker takes control.
Some ways to prevent this from happening, according to Tardini, include removing that privileged role from code, securing private keys through a multi-signature wallet or time lock, and turning to a decentralized autonomous organization (DAO) for community decision- making . - Logic problems and correction
Logic and correctness failures in smart contracts have to do with those errors that prevent their expected operation . An example of this would be a bad calculation in the rewards for staking a cryptocurrency or the lack of updating of some variable. Programming errors in the code are also included here.
Of the cases analyzed, 1,209 problems of this style arose. This could fit the episodes of Uranium and Compound mentioned above. According to Tarditi, these occurred due to the "omission of a single character in the code" that led to a protocol malfunction that hackers were able to exploit.
What can be done to prevent these failures? The main thing is to be very accurate and meticulous with your design documents and whitepaper, conduct a code review, and develop tests to catch these potential issues. - Complications with withdrawals
The third threat to Ethereum smart contracts according to David Tarditi is failures or complications with withdrawals. This is a type of vulnerability that occurred much less in the cases studied; it was only detected in 142 contracts, that is, almost 10% of logic and correction failures.
An example in this third category would be the blocking of funds in a smart contract, without the possibility of removing them by the user. It is something that can be corrected by following the advice in the previous point when creating, testing and correcting the protocol code. - Access control
Access problems are the fourth threat listed by this expert. They detected it in 120 smart contracts during their audits.Similar to the first item on this list, the vulnerability occurs when anyone can perform a sensitive operation of the contract even though they should not be able to. In this case, it would not occur due to the fact that this user has a privileged role, but rather it occurs from a flaw in the code that allows him to gain that power.
Again, this is a problem that can be detected from the good practices already mentioned above. In this regard, Tarditi stressed that these processes must be repeated exhaustively each time a change is made to the code of a smart contract. - Lack of limits
Finally, the problem of lack of limits could occur in a smart contract. A potential case would be the establishment of tariffs; if these are not capped and go too high, a large portion of the value locked in the contract could be lost when executing a liquidation or other function.
As this medium reported, in 2021 Ethereum rates had very high prices due to the congestion experienced by the network.
The problem of the lack of limits in smart contracts occurred to a lesser extent according to Tarditi's research, since 96 failures of this style were detected.
Ethereum smart contracts, in search of optimization
If there is something that stands out about the Ethereum network, it is the security and scalability it offers to operate with tools such as smart contracts. It is what differentiates Bitcoin the most and what separates it from its main competitors , which never came to overshadow it.
However, it is clear that there are still things to improve, and that is what experts like David Tarditi are working on. From the knowledge of the dangers and the application of the previous recommendations, a more secure environment can be generated that mitigates the attacks and contributes to the growth of the adoption of this network.

How smart contract auditing can help prevent attacks
As companies move towards the implementation of smart contracts , the need for technical audits becomes more and more essential. Having a third-party auditor check your contracts for vulnerabilities can prevent your company from being hacked.
What are smart contracts?
A smart contract is a script that automatically executes the provisions of a contract. Smart contracts are self-executing, which means that once the system has verified that the predetermined conditions are met, the contract will be executed automatically. This eliminates the need for intermediaries such as attorneys and escrow agents.
Smart contracts run on a blockchain, a distributed database managed by a computer network. This guarantees the faithful execution of the contract without any external interference.
How do smart contracts work?
When two or more parties enter into a digital agreement, it is usually a “smart contract”. Computers execute smart contracts and automatically enforce the terms of the agreement. For example, suppose you want to buy a new car from a dealer.
You and the dealer can agree on the price of the car and the terms of purchase. The smart contract will automatically execute the purchase, transferring ownership of the vehicle from the dealer to you.
Anyone can use smart contracts for various agreements, including financial transactions, voting, and other interactions. They are often used in cryptocurrency systems to enforce trading terms.
For example, when buying or selling Ether (ETH) on an exchange, the execution of the transaction is based on a smart contract. This ensures that the trade is successful and that both parties receive the ETH they agreed to trade.
You can also use smart contracts for other purposes. For example, you could use them to automatically send payments from one person to another. They could also be used to track ownership of assets such as land or property.
In the future, smart contracts could also automatically enforce the terms of legal agreements.
Smart contracts are still at the beginning of their development. As a result, the market has not yet explored many potential uses for this tool. As technology develops, smart contracts are likely to become more common and valuable.
Why are smart contracts vulnerable to hackers?
Smart contracts are vulnerable to attack because they consist of code that any experienced hacker can manipulate. Also, since smart contracts run on a blockchain, they are public and can be viewed and manipulated by anyone. This makes them susceptible to attacks and fraud.
Finally, many smart contracts do not go through the required testing and auditing stages before being activated. This issue can lead to vulnerabilities that hackers can exploit.
Despite these risks, smart contracts can potentially revolutionize the way we do business. They can automate transactions, reduce costs, and increase transparency. When considering the use of smart contracts, it is essential to be aware of the risks and take steps to mitigate them.
What is the role of a smart contract auditor?
A smart contract auditor is a professional who verifies the security of a smart contract. They make sure that the code is free of bugs and vulnerabilities that could lead to loss of funds or other issues.
Auditors also help assess the risk of a smart contract before its developers implement it. This allows projects to make informed decisions about whether or not to use a specific smart contract.
Control of smart contracts is critical to the security of the entire cryptocurrency industry. By ensuring contracts are secure, auditors help protect users and projects from loss of funds.
If you’re interested in becoming a smart auditor, you need to know a few things. First, you need to understand Solidity , the programming language used to write most smart contracts. You should also be familiar with security best practices and be able to identify potential vulnerabilities in your code.
There are several ways to get started as a smart contract auditor. You can join an accounting firm, go freelance, or even create your own audit practice. These companies follow strict security protocols and have a team of experienced auditors.
How does a smart contract auditor detect vulnerabilities?
A Smart Contract Auditor is responsible for detecting vulnerabilities in smart contracts. They use various methods to accomplish this, including code audits, security reviews, and penetration testing.
By identifying and fixing vulnerabilities early, smart contract auditors can help protect businesses and users from loss or damage.
There are a few key things to consider when auditing a smart contract:
Auditors check contract code for potential vulnerabilities;
Perform a contract security review to identify any risks;
They often perform a contract penetration test to see if criminals can hack it.
code audit
A code audit consists of examining a piece of code for possible errors. This is important for smart contracts, since the code is the basis of the contract.
If there are bugs in the code, they could cause serious problems across the board. That’s why it’s vital that you thoroughly review the code before signing it.
There are a number of things a reviewer should keep in mind when performing a code check. For example, we can mention:
Check for violations of coding standards;
Look for possible security vulnerabilities;
Check if the program works as expected;
Check for logical errors.
Running a code check can be time consuming, but getting it right is essential. Making sure that your code is free of bugs can help reduce the risk of problems in the future.
Suppose you are verifying a smart contract intended to send money from one person to another. The first thing you should do is check your code for coding standards violations. This includes making sure the code is properly formatted and easy to read.
Next, it will scan for potential security vulnerabilities. This means looking for unsafe random number generators, possible integer overflows, or other related problems.
Next, you need to verify that the code works as expected. This includes testing the contract to make sure it works as intended.
Finally, you should check for logical errors. This means making sure that the code makes sense and that there are no obvious errors.
security reviews
Security reviews are essential to identify contract vulnerabilities before external parties can exploit them. By identifying and mitigating risks up front, companies can save themselves a lot of trouble.
Some common risks that are often present in contracts include:
Lack of access control measures;
insecure data storage;
Weak authentication and authorization mechanisms;
Insufficient security controls.
By identifying these risks early, companies can take steps to mitigate them before they cause damage. This can save the company a lot of money, time, and effort in the long run.
Penetration tests
Penetration tests simulate real-world attacks to identify any security weaknesses. These tests are vital because they can help prevent attacks in the first place. By identifying these weak points, businesses and users can stay safe.
Penetration testing is possible in many ways. One way is to use automated tools that launch attacks against a system and then analyze the results. Another way is to hire ethical hackers, also known as white hat hackers, to try to break into a system.
Penetration tests usually consist of three stages:
Information Gathering — The tester collects information about the target system at this stage. Reviewers may collect this information manually or through automated tools.
attack : At this stage, the tester tries to break into the system. Testers (or “ethical hackers”) can do this in a number of ways, including brute force attacks, SQL injection, and cross-site scripting.
Report : In this stage, the tester writes a report detailing the results of the test. This report is the starting point for improving system security.
Regardless of the method a project uses, the goal is to find any vulnerabilities in the code. This way, developers will have a chance to fix them before a real attacker finds and exploits them.
Prevent hacks through smart contract auditing
A blockchain hack can be a catastrophic event, with consequences that disrupt the entire ecosystem. To prevent attacks, it is vital to perform a smart contract audit before deployment .
An audit involves examining a smart contract to identify vulnerabilities and making fixes where necessary. By verifying your contracts, you can help ensure that your transactions are safe and secure.
There are several methods to control a smart contract. One option is to use a tool like Solium, which can automate the process. Another option is to hire a company that specializes in blockchain security.
Whichever route you choose, double check any third party before handing over your code. And always remember: never implement a smart contract without verifying it first. In the worst case, a hack could cost you your entire investment and your crypto project could lose credibility.
Bottom line
Smart contract audits are essential for ensuring the security of your transactions. You can help ensure the security of your transactions by verifying your contracts.
There are several ways to audit a smart contract. A typical option is to hire a company that specializes in blockchain security. As the use of smart contracts increases, the need for audits will also increase.
A small investment in an audit could go a long way. It might even save you from a hack that could cost you your entire investment. So it comes as no surprise that the smart contract auditing niche is becoming more and more popular.
