About security

Web3 Antivirus (W3A) is a multi-layered security platform for crypto users. Its core product is a free browser extension that simulates transactions, detects phishing sites, and warns about risks before you connect a wallet or sign anything. It also offers a security dashboard, MetaMask Snap, and a Telegram Mini App.


Key Features

  • Transaction simulation and risk analysis before signing
  • Protection against 60+ scam types (honeypots, wallet drainers, address poisoning, fake tokens, malicious approvals, etc.)
  • Phishing dApp and lookalike site detection
  • Toxic Score for wallet health
  • One-click high-risk approval revocation
  • AML / address screening insights
  • MetaMask Snap for in-wallet warnings
  • Telegram Mini App for mobile checks
  • Complements popular dApps (1inch, DeBank, Etherscan, OpenSea, etc.)


How it works

The extension runs in the background. When you visit a site or initiate a transaction, it analyzes the contract and potential outcomes, then shows clear color-coded risk warnings. The dashboard lets you monitor wallet risk and revoke dangerous approvals.
