Web3 is a revolutionary technology that has enabled users to make secure and trustless transactions with cryptocurrency. However, it is important to be aware of the risks associated with these transactions and take precautions to minimize fraud. In this blog post, we will discuss how to protect yourself from malicious actors when using web3 technology. 

We will look at the recent case of a user being scammed out of their Ethereum by signing a transaction they were not aware of, and how this could have been avoided. We will also discuss the importance of verifying everything yourself, understanding the code for contracts you interact with, and taking advice from experienced investors. Finally, we will provide tips on what to do if you encounter an issue while running a react contract on Truffle.

Overview of Fraud in Web3 

Fraudulent activities are a major concern in the world of web3 and cryptocurrency. With the decentralization of digital assets, malicious actors have more opportunities to take advantage of unsuspecting users. In order to protect yourself from fraud, it is important to understand the different types of scams that can occur. Common scams include phishing attacks, fake wallets, and malicious contracts. It is also important to be aware of the risks associated with signing transactions and verifying code. By taking these precautions, users can minimize their risk of becoming a victim of fraud in web3.

Risks associated with Distributed and Decentralized Networks 

Distributed and decentralized networks can provide a great deal of freedom and autonomy to users but they also come with their own set of risks. As the user is responsible for their own security, they must be aware of the potential risks associated with their transactions. 

These include the risk of malicious actors attempting to scam users out of their funds, as well as the risk of signing random byte hashes which could lead to the user being scammed. Additionally, users should always be aware that there is no shadowy organization orchestrating malicious activities, and that traditional financial instruments and entities have additional protections in place that do not exist in the crypto world. To minimize fraud, users should take responsibility for their own security by reading the code for contracts they interact with, verifying transactions themselves, and avoiding things that are “stupid, evil, and make them look bad”.

Never Sign Random Byte Hashes 

When dealing with cryptocurrency transactions, it is essential to remember never to sign random byte hashes. Signing a hash means that you are authorizing a transaction, and if you do not understand the implications of what you are signing, you could be tricked into sending your funds to a malicious actor. It is much safer to sign text messages as this attaches your identity to the transaction and makes it more difficult for scammers to steal your funds.

Additionally, it is important to understand that no one is in charge of orchestrating malicious activities in the crypto world, so users must take responsibility for their own security and be aware of potential risks. Finally, always verify the code for contracts before interacting with them and remember to include screenshots when asking for help online.

Sign Text Messages Instead 

Signing text messages is a much safer way to protect yourself from malicious actors when using web3. When signing a text message, it attaches your identity to the transaction, making it more difficult for someone to steal your funds. This is because it requires the user to verify their identity before sending the transaction. Users must take responsibility for their own security and be aware of potential risks. Furthermore, users should always read the code for any contracts they interact with in order to understand how they work and ensure that they are not being scammed out of their funds.

Take Responsibility for Security 

With cryptocurrency, security is always a top priority. With decentralized networks and transactions, it’s important for users to take responsibility for their own security and be aware of potential risks. Here are some tips on how to minimize fraud and protect yourself when using web3 applications.

  1. Be cautious of who you trust. Anyone can create a contract or transaction, so it’s important to be careful about who you trust with your money.

  1. Verify everything yourself. One of the benefits of decentralized applications is that you have the ability to verify everything yourself. Before interacting with any contract or transaction, take the time to understand how it works and check the code for any vulnerabilities.

  1. Use a secure wallet. When it comes to storing your cryptocurrency, use a secure wallet that supports multiple signatures. This will help protect your funds in case of theft or fraud.

  1. Keep your private keys safe. Your private keys are what give you access to your cryptocurrency, so it’s important to keep them safe and secure. Never share your private keys with anyone, and be sure to store them in a safe place.

  1. Stay up to date on security threats. Be sure to stay up to date on the latest security threats by subscribing to security mailing lists and following security news sources. This will help you stay informed of any new risks that may arise.

Verify Code for Contracts 

It is important to verify code for contracts interacted with. By verifying the code, users can ensure that the contract will behave as expected and that there is no malicious code included. Additionally, signing text messages rather than random byte hashes can help to protect against scams. Finally, users should be aware of the risks associated with any transaction and take responsibility for their own security.

Working Through Tutorials and Using Resources like Dapp University

However, there are steps that users can take to minimize the chances of being scammed. One of the most important things to do is to educate yourself about the technology and how it works. This way, you'll be able to better understand the implications of any actions you take, and be less likely to fall for scams.

There are plenty of resources available to help you learn about web3 and cryptocurrency. Tutorials like CryptoZombies can give you a basic understanding of how the technology works, while Dapp University is a great resource for learning about cool web3 projects. It's also important to ask for help when you need it, and to be as specific as possible when posting about your issue - a screenshot can go a long way in helping others understand your problem and offer solutions.

By taking some simple precautions, you can help reduce the chances of being scammed when using web3 and cryptocurrency.


Fraud is a major risk in web3, and it is important to be aware of the risks associated with distributed and decentralized networks. There are several steps you can take to minimize fraud in web3. Never sign random byte hashes, sign text messages instead, take responsibility for security, verify code for contracts interacted with, and get investing advice from the world’s best investors. Additionally, you should work through tutorials and use resources like Dapp University to help you understand how to interact with contracts safely. If you ever encounter an issue, don’t hesitate to ask for help online with screenshots of the problem. By following these steps, you can ensure that your web3 experience is secure and fraud-free.
