The security tool protects you from web3 scams by auditing transactions and detecting phishing websites

Web3 Antivirus protects you from crypto scams by auditing transactions and detecting phishing websites. 🛡 In Web3, it only takes one signature to lose everything you own. This web3 security browser extension helps you keep your crypto assets safe from scams and wallet drainers. How it protects you: 🔄 Transaction analysis Web3 Antivirus warns you about honeypots, wallet drainers, malicious transactions, wash trading patterns, poisoning attacks, and more. Before you sign a transaction or connect your wallet, W3A checks for potential risks and simulates the transaction to show what happens if you approve it. You will clearly see what you receive and what you give away as a result of the transaction. ⚠️ Risky open approvals and wallet health monitor Revoke high-risk token approvals to dApps, review your web3 interactions, check other users’ wallets before interacting with them—all in one place. 🎣 Phishing and impersonation 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. *** 🔐 Privacy Web3 Antivirus doesn’t have access to your wallet or assets and never asks for your seed phrase or other personal information. 🔍 Transparency This wallet security tool is open-source and we encourage users to check our GitHub repository:
