WHAT’S INSIDE

Web3 Antivirus installs as a browser extension. It vets the parties and
properties you interact with on Web3 to warn you before you take potentially
dangerous actions.

Keep in mind: Web3 Antivirus will never ask for access to your wallet, assets,
or for your seed phrase.


 * SMART CONTRACT ANALYSIS
   
   Web3 Antivirus audits smart contracts behind transactions to identify
   dangerous logic, critical vulnerabilities, and compromising permissions to
   access your assets.


 * TOKEN ANALYSIS
   
   W3A checks token’s characteristics such as creation date, collection, and
   owners as well as collection’s smart contract to determine that the
   transaction is safe.


 * TRANSACTION SIMULATION
   
   To be certain that the transaction is riskless, W3A checks all smart
   contracts tied to it and stimulates the flow of the transaction to see the
   outcome.


 * PHISHING WEBSITE DETECTION
   
   While you browse through Web3 space, W3A checks domain names against
   extensive blocklists and allowlists using AI similarity validation, and
   alerts you if it detects phishing.

I like the idea of an antivirus available to use even in web3. Considering its

The tool ensures a contract doesn’t request too much access - Hmm, that seems
interesting. I have never seen this.

ANY QUESTIONS LEFT?

Browse our FAQs below or email our friendly team at: support@w3a.tech

 * How do I know this is safe?
   
   Web3 Antivirus can be added to your browser as an extension directly from the
   official stores:
   
    * Chrome Web Store
    * Microsoft Edge Add-ons
    * Add-ons for Firefox
   
   It is also open-source so you can see everything it’s able to do. Visit our
   GitHub repo to build your own copy.
   
   Note: Web3 Antivirus (W3A) will never ask for your seed phrase, it cannot
   access your wallet, and it does not require any information that should be
   kept secure.

 * How is W3A different from other traditional antivirus software?
   
   Web3 Antivirus addresses specific web3 security issues that are not covered
   by traditional antivirus protection.
   
   Traditional antivirus attempts to protect your computer by preventing
   malicious software downloads and stopping the execution of harmful code.
   Attempts to gain access to your wallet and assets via phishing or fraudulent
   smart contracts would go completely undetected by traditional antivirus
   software.
   
   This is where Web3 Antivirus comes in as an essential layer of protection
   between your assets and web3 scams.

 * How exactly does W3A protect me?
   
   W3A stands guard while you browse the internet, investigating the other
   parties and assets which you interact with.
   
   The extension offers proactive phishing protection. It checks domain names
   against its database of blocklists and whitelists using AI similarity
   validation and immediately alerts you if you’re heading to a phishing site.
   
   When you’re about to sign a transaction or a message, W3A briefly pauses it
   and analyzes for red flags. It uses proprietary security audit frameworks to
   detect honeypots, suspicious logic, dangerous functions, compromising access
   permissions to assets, wash trade patterns, and other threats. The tool also
   simulates the transaction and shows what happens if it’s approved. You will
   clearly see what you will receive and what you will give away as a result of
   the transaction.
   
   Within a few seconds, W3A summarizes all the potential threats in a report.
   With all the information in hand, you can decide whether or not to proceed
   with it.

 * How do I use W3A?
   
   The installation is simple and quick. Choose the option that works for you
   and add the extension from:
   
    * Chrome Web Store  to Chrome and Brave browsers.
    * Microsoft Edge Add-ons  to the Edge browser.
    * Add-ons for Firefox  to the Firefox browser.
   
   Or install it directly from the GitHub open-source repository.
   
   Once it’s enabled, it begins working immediately and alerts you anytime you
   have a wallet transaction call or browse to a potentially threatening site.
   
   Note: Web3 Antivirus (W3A) will never ask for access to your wallet, your
   assets, or your seed phrase.

 * Do I ever need to provide my seed phrase?
   
   No. Web3 Antivirus never asks for your seed phrase and has zero access to
   your wallet and its assets.

 * How does transaction simulation work?
   
   Transaction simulation helps to show you what happens if you approve a
   transaction. This means you can discover potential vulnerabilities or side
   effects without compromising the security of your wallet. You will also
   clearly see what you will receive and what you will give away as a result of
   the transaction.
   
   To execute the simulation, W3A analyzes the smart contract behind the
   transaction and traces each call that the contract makes. It then audits
   those connected contracts in the same manner and shows you the result of the
   contracts’ full execution.

 * Can I try W3A for free?
   
   Yes. Our basic plan is completely free. The extension can be installed
   directly from:
   
    * Chrome Web Store  to Chrome and Brave browsers.
    * Microsoft Edge Add-ons  to the Edge browser.
    * Add-ons for Firefox  to the Firefox browser.

 * What is next for Web3 Antivirus?
   
   We constantly upgrade Web3 Antivirus enhancing its abilities and improving
   auditing methodology to detect various threats and scams within seconds.
   
   We’re also adding support for new browsers, wallets, and blockchains.
   
   Check out our blog for updates and release notes for new versions of the
   extension.
   
   Soon-to-be-released features include the W3A Dashboard which allows you to
   see logs of threats you’ve encountered, detailed transaction lists, and
   delegated token rights.
