The NFT industry surged in 2021, reaching a value of roughly $22 billion and drawing in about 185,000 distinct wallets in addition to an estimated 280,000 buyers and dealers.

However, as the market has expanded, cybercrime has also expanded, as seen by eye-catching instances of NFT fraud, NFT art scams, and NFT game scams. Continue reading to find out more about NFTs and how to evade NFT fraud.

Learning to recognize these frauds and then avoiding them at all costs is the best defense against them. We have listed down the most typical NFT frauds, and the way you can avoid them? 🤔

Impersonation 

There are third-party markets like OpenSea that help with NFT transactions and offer security for each sale. But to trick users, fraudsters might put up dummy marketplaces with similar URLs. An NFT’s visible component is an easily duplicated image and some unencrypted data, therefore these websites can resemble actual marketplaces quite closely.

Phishing scams

 One of the most typical scams is phishing. On a variety of sites and applications, such as Discord, Telegram, WhatsApp, Facebook, and Instagram, this happens when attackers distribute nefarious links. The link frequently directs the victim to a false NFT minting page, which, if signed, enables the con artist to steal money from the victim. There are several variations of this fraud, such as when an NFT project’s official Discord account is hacked, enabling attackers to utilise the channel to spread their malicious “honey pot” link.

Customer Support Impersonation

 Scammers frequently use bogus customer care pages for legitimate NFTs to obtain private information from unaware NFT owners. On Discord, where many NFT project communities are housed, this is rather typical. Scammers may ask you for private information, such as your private key or seed phrase, in order to “repair” whatever issue you may be experiencing if you connect to one of these fraudulent customer service servers rather than the real one. If this is a concern for you, think about how you typically access NFT Discord servers. Try finding a server via the NFT creator’s official website or social media first rather than just searching for it on Google or Discord.

Rug pulls

 Rug pulls are well-known in the NFT industry. These are frauds in which the project’s originator (or project founders) advertise a venture’s apparent aim without intending to see the objectives achieved. They are frequently referred to by the shorter “rug.” In the end, the fraudsters solicit money — often through NFT mints — and steal it (also known as “rug pulling”) without making any effort to advance the initiative. Find out more about the teams behind NFT projects by looking them up on social media sites like Linkedin and Twitter. The crypto community may even know and trust anonymous artists and engineers, but it is still crucial to carefully examine follower counts and interaction on social media. Check the project’s road map to see if it’s realistic.

The sheer variety of modern scams that you can fall for is a little frightening. Every other week, cybercriminals come up with new schemes to deceive people as they get more and more creative. But if you remain cautious and knowledgeable about the various scams that exist and how to spot them, you’ll undoubtedly keep yourself safe when exploring the fascinating world of NFTs.

Smart contracts are computerized transaction protocols tailored for executing the terms of a contract. Primarily, smart contracts are created for addressing mutual conditions while reducing accidental exceptions and the involvement of intermediaries.

A smart contract security audit provides a detailed analysis of a project’s smart contracts. These are important to safeguard funds invested through them. As smart contracts are immutable once deployed, it is important to go through all the checks and ensure there are no loopholes in the code. Deploying smart contracts without proper audits could result in untoward circumstances such as discrepancies in the desired performance of the contract. At the same time, inadequate audit processes could also land you up with risks such as loss of personal data or data theft.

Process of Smart Contract Auditing

1.Agreement on Specification

The first step in the process focuses on reaching an agreement regarding the specification of smart contracts. The smart contract specification and other related documentation provide a clear explanation for the architecture, build process, and design choices of a project. The lack of a specification would leave auditors without any idea regarding the desired and actual working of the code. Therefore, the first phase of how to audit a smart contract starts with a full specification of the project.

2.Testing Process

Testing is one of the significant factors which maximize the smart contract audit cost. Testing also offers simple and easy approaches for bug detection. Different options are available such as unit tests for targeting individual functions or integration tests focused on concerns of larger code.

3. Manual Analysis

Manual inspection is a necessary requirement for improving the detection of possible smart contract code vulnerabilities. An experienced auditing team evaluates the specification for confirming the performance of a project according to desired functionalities.

4.Automated Analysis

The projects that require faster time-to-market often prefer an automated approach because it helps find vulnerabilities much faster.Automated analysis tools could evaluate a program for determining the inputs which trigger the execution of each part of the program. These tools help in streamlining the audit process by improving the ease of identification of general issues in code.

5.Audit Report

The final step in smart contract audit is the creation of an audit report. The auditors should create a detailed audit report after completing the tests, automated analysis, and manual analysis process.

Advantages of Smart Contract Audits

1.Better optimization of the code as they improve Gas Efficiency as well.

2. Improved performance of smart contracts as most of the vulnerabilities will be removed post the audit. This leaves little to no room for performance degradation.

3. Enhanced Security of Wallets.

4. Security against hacking attacks such as:

Reentrancy attack

Reordering attack

Short address attack

Over and underflows

Replay attack

Hence, it is quite clear that Smart Contract Auditing is a crucial step in developing an error free and optimized code. A simple line of code could be the difference between a successful and a misused contract.

We saw some significant crypto-related projects crash in 2022, which caused Web3 to experience considerable setbacks.

However, technological advancement and innovation are still going strong, therefore 2023 needs to be a year with increased risk appraisal and assessment. There are a number of services planned that, over time, will become popular in order to promote Web3.According to Web3, we now have the means to build online places that are genuinely ours, as well as to implement digital democracies, thanks to technologies like blockchain, cryptocurrencies, non-fungible tokens, and decentralised autonomous organisations (DAOs).

On the internet, we have come a long way; in the beginning, this was unthinkable. Web3 is currently the subject of agreements and controversies, yet it has a lot to offer. Businesses adopting Web3 and blockchain are preparing for the future by figuring out how to help their customers and clients get more done with less. With improved infrastructure, more human-centered and holistic Web3 trends will be visible soon.

The top web3 trends in 2023:

By 2030, the Web3 niche market will expand by 41% and address many of the problems currently experienced by internet users.

Gaming

The use of Web3 UI/UX and the usage of blockchain in gaming have both recently increased. There will also be more play-to-earn games available. There will then be a carefully considered game economy. In addition, markets will experience a 50% increase in the gaming market over the following four years.

NFTs

NFTs were a significant trend in 2021 but lost steam in 2022. This is advantageous for technology since developers will need to offer more value to attract users. Future value-added drops ought to exist since an NFT with no value will collapse. Companies must educate themselves on utility NFTs, which are much more than just works of art. NFT tickets, for instance, are one method. It is a fantastic approach to involve customers for merchandise and special events.

Decentralized Autonomous Organizations (DAO)

DAOs are not a new concept in cryptocurrency, but they haven’t yet reached their full potential. We can quickly identify use cases for that kind of organisation even by looking at a few recent events. Look at Elon Musk’s poll to see if people think he should continue leading Twitter. He stated that he would follow the poll’s findings, and it turned out that the public wanted him to resign. Who did the voting, though? Could computer programmes manipulate the poll? Obviously, it might. A DAO would at least be able to verify such a vote on-chain and link it to the assets of the voters.

GameFi

The idea of GameFi or the metaverse most likely originated from NFTs. It gives games more economics that players can use to their advantage. The assets can be exchanged across worlds and games, traded on outside markets, and they don’t even have to be a part of one game.

Regenerative Finance (ReFi)

DeFi is an extension of what you may have heard. It blends the decentralised finance idea with the regenerative economics idea. Imagine you own a green, beautiful piece of land. You can give the land area a monetary value with ReFi. The Web3 is a platform that users may access using a wallet to invest in, purchase, or exchange natural resources. In order to protect the environment, regenerative finance is thought to be just and long-lasting.

You may have seen many posts about how to write your first Contract in Solidity. In fact, you must be tired of seeing these rudimentary posts about Solidity. 

Even we made a 5 Step Process to become a Solidity Developer.

Well, we promise you- this post is not the same.

This article will teach you what other developers are scared to learn.

So you have written a Smart Contract in Solidity? But what’s next?

Is it production ready? Is it even portfolio ready?

It’s not until you have optimised your gas!

Here are the top Gas Optimization Techniques to upgrade your Smart Contracts to the next level:

Use Solidity Gas Optimizer:

The Solidity Gas Optimizer works to make complex expressions simpler, which minimizes the size of the code and the cost of execution via inline operations, deployments costs, and function call costs.

Delete Variables that are not needed:

This should be a no brainer!

Deleting a variable refund up to 15,000 gas.

Use bytes32 instead if uint8:

If the string you are dealing with can be limited to max of 32 characters, use bytes32 instead of dynamic bytes array or string.

Use Mappings instead of Arrays:

Except where iteration is required or data types can be packed, it is advised to use mappings to manage lists of data in order to conserve gas. This is beneficial for both memory and storage.

Pack your Variables:

Packing variables into one helps in using wasted space.Most of your variables will not be using the complete space they are initialized with. Packing two or more variables will guarantee no unused space is left behind.

Use External Modifier instead of public:

The Public visibility modifier is equivalent to using the External and Internal visibility modifier, meaning both public and external can be called from outside of your contract, which requires more gas.

Don't initialize Variables with Default Values:

If a variable is not set/initialized, it is assumed to have the default value . Explicitly initializing it with its default value is an anti-pattern and wastes gas

Make State Variables Immutable if Possible:

Calling state variables from storage costs 100 gas. Making them Immutable will cost you 3 gas!

Well done!

Now you know some of the best ways to save gas on your Smart Contracts. 

Recorem is the First Decentralised talent discovery platform that advertises jobs in events and shares revenue with the applicants and the event partners.

So apart from this, what is unique about this platform?🤔

Our founders figured out how Web3 is a niche, unique industry and the recruitment or the recruitment process here is quite different from other industries.

People here tend to collaborate and work with others and henceforth this industry runs on communities. These communities basically do events on a regular basis and this is where the need for top skill talent of Web3 comes into play.

Our founders, being professional recruiters, created Recorem as the traditional recruiting channels are saturated. Sourcing skilled passive talent is challenging and time consuming due to limited supply of candidates on existing platforms. The success they found in finding talent from meetups and conferences led to the creation of a platform to enable this at scale.

And this is how Recorem came into place. Our founders have been in the recruitment industry for 20 years now and they understand the crux of recruitment. They understand every inch of recruitment. The product is unique in a way that at one point of time, companies and attendees can attend more than 1 event.

At Recorem, we can attend more than 1 event at a single point of time. It also offers various opportunities for event organizers and recruiting companies where it helps hiring companies to hire top skill talent using augmented intelligence matching engine

Recorem allows to discover talent from untapped, niched talent pool of events in web3.

 ‘Self Starter’

When you hear this word, what is the first thing that comes to your mind?

Initiative? Independent? Risk taker? Self-sufficient?

Being a self-starter is all about how well you can do things on your own without the supervision of your senior or manager.

Every manager seeks out team members who are motivated and driven for their own sake. Leading innovative projects and showcasing your independence from micromanagement can help you stand out from your coworkers. Going above than the standard set at work demonstrates your dedication to the organization's success.

So consider that you are the average of the five individuals you spend the most time with. Think about that for a minute. After reviewing your objectives, turn to the individuals next to you.

Now throwing out friendships or refusing to talk to your coworkers will not make things facile for you but to be a self-starter mixing things up a bit is a crucial step. Make sure you don’t get dragged into the complaining party or people who indulge in negative self-talk. Your focus should be on your work and the goals to be achieved.

When it comes to recruiters, they also look for focused candidates with a positive attitude towards work. Organizations seek out employees with a positive attitude because they believe that optimistic people have a winning mindset. A person with a positive outlook is more likely to be hired since they can confidently face failure and competition.

That’s why Recorem brings to you the best passive Web3 talent at scale.

We provide candidates with the passion and desire to give their best at work.
