Project goals

To bring their idea to life and ensure flawless technical realization, the client reached out to PixelPlex and our team of seasoned blockchain developers.

Together, we outlined the core goals of the Web3 Antivirus project:

  • 1

    Build a robust security solution that will allow users to conduct safe transactions and interact with others in the web3 space

  • 2

    Create an ML algorithm able to instantly detect fraudulent activity and dangerous websites

  • 3

    Provide multi-browser and multi-chain support

  • 4

    Allow for intuitive navigation through the solution components and ensure easy-to-understand reporting

Solution

With these goals in mind, PixelPlex built Web3 Antivirus (W3A), an ML-powered browser extension that helps users explore and operate in the web3 space with full confidence by detecting crypto-related scams and suspicious activities.

The blockchain already under Web3 Antivirus protection is Ethereum, with Polygon, Arbitrum and BNB coming next.

Eth logoprotected.

Smart contract analysis

Web3 Antivirus thoroughly examines smart contracts that users interact with. It conducts static analyses, inspects the execution logic, searches for suspicious methods and deviations from commonly accepted standards.
Users are promptly notified about any potential risks, harmful logic, vulnerabilities, or compromising permissions. Additionally, they have the option to manually input a contract address for verification.
Some of the smart contract risks detected by the extension include:
  • Malicious code patterns and methods
  • Metamorphic code
  • Dangerous signing requests
  • Honeypot scams
  • Self-destruction
  • Pausable contracts
  • Burnable tokens
  • Trading cooldown
  • High sale taxes
Moreover, W3A's risk scoring framework takes into account third-party audits when identifying smart contract risk coefficients.

Transaction simulation

Web3 Antivirus performs real-time transaction simulations to reveal issues that may arise if users proceed with the transaction. This way, users can discover potential risks, vulnerabilities, or transaction side effects without compromising their assets or wallets. Simulations also help detect dangerous or fraudulent assets, like honeypots, before users buy them.
To execute the simulation, W3A runs the transaction in the dedicated testnet and analyzes the whole chain of smart contracts behind a transaction. The outcome is presented to users in the form of an easy-to-understand chart.

Token analysis

W3A users can access detailed information about token characteristics, including token type, creation date, maximum and circulation supply, price, and contract address.
Additionally, the solution performs extensive analysis of NFTs, identifying risks like wash trading, missed royalty payments, IP infringements, and suspicious previous owners. It also provides financial and historical metrics through a unique 12TB data layer.
For a more comfortable experience, Web3 Antivirus shows the fiat equivalent of a token’s price. This way, users don’t have to convert the prices themselves.

Fair price

When a user places a bid to purchase an NFT, W3A's machine learning module calculates a fair price for the token, considering its previous sales and involvement in wash trading. This feature safeguards users from price manipulations, ensuring they don't overpay for the asset.

Risk reporting

The solution provides detailed risk reporting to help users see what dangers they may encounter.
W3A reports are color-coded for easy understanding: high risks are indicated by red, medium by yellow, and low by green. Each report features a list of detected threats and an explanation of how exactly each risk can affect user assets.

Website analysis

To ensure websites pose no threat, Web3 Antivirus verifies their domain names against carefully curated blocklists and allowlists using AI-powered similarity validation. This helps detect typosquatting, phishing attacks, and brand impersonation, further enhancing user security.
