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.
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.
The installation is simple and quick. Choose the option that works for you and add the extension from:
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.
No. Web3 Antivirus never asks for your seed phrase and has zero access to your wallet and its assets.
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.
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.
