Protects your crypto wallet from phishing and scam transactions.

Web3 Antivirus acts as a security layer when you make transactions with your crypto wallet or browse websites. It leverages transaction simulation and proactive phishing detection to warn you about any risks before you connect your wallet or sign anything. In Web3, it takes one wrong signature to lose all your crypto. Web3 Antivirus is a security browser extension that helps you understand exactly what you're signing and what happens if you approve. How it protects you: 🛡️Transaction analysis Web3 Antivirus provides security against 60+ types of scam: honeypots, wallet drainers, malicious transactions, fake tokens, poisoning attacks, and more. Before you sign a transaction or connect your crypto wallet, W3A simulates the transaction to show the potential outcome and validates whether it's dangerous. 🛡Crypto phishing protection Phishing and impersonation are the most frequent scams in Web3. Web3 Antivirus offers proactive phishing protection and immediately alerts you if you’re heading to a phishing site. 🛡️Risky open approvals and wallet health dashboard Maximize your wallet’s security. Revoke high-risk token approvals, review your web3 interactions, check other users’ wallets before interacting with them—all in one place. *** 🔐Privacy Web3 Antivirus doesn’t have access to your
