What are the most common web3 scams?

Main web3 risks

Web3 scammers are creative in the extreme, coming up with sophisticated fraud schemes designed to catch you off guard and steal your crypto assets. The most common dangers you may face in the web3 space include phishing websites, malicious messages, malicious smart contracts, copymints, rug pulls, poisoning attacks, fake airdrops, and impersonation.

Let’s take a closer look at how these web3 scams work.

Phishing websites

Phishing websites imitate domain names and design of official websites and lure you into disclosing your wallet credentials. For example, or can claim to be, one of the top NFT marketplaces.

Malicious messages

Phishing websites often try to trick a user into signing a message looking similar to an authentication request or a sign-up for a whitelist. In reality, after signing this message it is very much likely that all user’s assets will disappear from their wallet.

Malicious smart contracts

Web3 fraudsters can encode some kind of dangerous logic into their smart contracts, such as the ability to pause and restrict a transaction, delegate calls to other contracts, burn tokens, give the contract creator access to all assets in the user’s wallet, and more.

Plus, scammers can exploit vulnerabilities of already existing contracts such as errors in contracts’ logic, default visibility, or timestamp dependence.

Copymints are plagiarized or fake NFT collections that violate authors’ rights. Such tokens have no collector value and are banned by the marketplaces. So if you happen to buy a copymint, you will not be able to sell it on any reputable marketplace.

Rug pulls

Rug pull is a scam happening when fraudulent developers create artificial hype around their projects and make them seem very promising and trustworthy. However, once such projects collect the intended amount of investors’ money, all traces that they ever existed disappear.

Poisoning attacks

In a poisoning attack, scammers deceive users into sending their assets to a fraudulent address. They achieve this by creating a deceptive address that closely resembles one the user has previously interacted with. Then fraudsters “poison” the user’s transaction history with this address by sending them a small amount of crypto.

This way scammers hope that next time the user sends assets, they will mistakenly copy the fabricated address instead of the actual one and send funds right to the attackers.

Fake airdrops

New W3A projects often launch airdrops to attract public interest. Scammers see it as an advantageous opportunity to fool people and create fake airdrops.

Here’s how it typically unfolds: fraudsters send emails or text messages claiming that the user has been randomly selected to receive free tokens and provide a link for claiming them. The link transfers the user to a phishing website that prompts them to connect their wallet. As you’ve already guessed, the next moment this wallet gets drained completely.


Impersonation scams happen when fraudsters pretend to be some crypto celebrity or a team member of a successful web3 project. The goal is to deceive users into revealing their wallet credentials or transferring their assets to the scammers.

Additionally, W3A simulates a transaction to show exactly what assets a user will grant access to, give away, and receive.

The extension conducts thorough examination of a token’s characteristics such as its type, creation date, owners, price, and smart contract to determine whether the transaction is safe. In addition, it has a specific module for non-fungible tokens analysis.

PixelPlex web3 safety tips

Over the time spent working on numerous web3 projects, our team has gained invaluable insights on how to stay safe in the web3 space. Based on that experience, we have prepared a list of the key safety measures you should take to feel protected while exploring web3.

Tips on how to stay safe in web3

1. Never share your private key and seed phrase

Take care to store your private key and seed phrase in a highly reliable and confidential way and never share them with anyone. Once you disclose these credentials, your wallet and all assets in it are compromised.

The best option is to write them down on a piece of paper and hide it in a safe place. We do not recommend keeping private keys and seed phrases on your computer or phone as they can be hacked.

2. Choose a non-custodial wallet

The crucial advantage of non-custodial wallets over custodial ones is that the user is entirely responsible for the safety of keys. Some of the most popular non-custodial wallets include MetaMask, Ledger Nano X, Exodus, and Coinbase Wallet.

For increased security, choose a hardware wallet/cold wallet, rather than a software-based hot one. These wallets keep your tokens disconnected from the internet entirely for an additional layer of safety. The list of best cold wallets include Trezor, Atomic Wallet, and SafePal S1.

3. Use several wallets

It is highly advisable to have several crypto wallets. So, for example, you can have a wallet holding your most valuable assets and a wallet that you use to make transactions and connect to dApps. This way, you can store precisely the amount and type of tokens you need for a particular transaction without exposing all your assets to risks.

4. Do your research

Never invest in a crypto project or a token without a thorough research on its founders, background, and whitepaper. This will help to ensure the credibility and reliability of the project.

5. Use trusted platforms

Opt for well-known and tried-and-true platforms for buying, selling, or exchanging your crypto assets. These platforms maintain strong safety measures since a security breach can greatly damage their reputation and lead to financial losses.

6. Stay focused

Be very attentive when signing a message or a transaction, and double-check all details, including sender and recipient address, the list of tokens involved in the transaction, etc.

Also, pay great attention to the links you follow, since phishing websites often mimic reputable ones.

7. Update your software regularly

If you forget to timely update your software, especially your crypto wallet, you may miss

important security enhancements and critical bug fixes. So, remember to make regular revisions of your software to ensure you have the latest versions.

8. Install a robust web3 security tool
