What Web3 Antivirus does
Web3 Antivirus (W3A) is a privately held Delaware-incorporated Web3 security company founded in December 2022 by Alex Dulub and headquartered in Wilmington, with a distributed operating team of 11-50 employees. Its core product is a free, open-source browser extension for Chrome, Firefox, Edge, and Opera that scans blockchain transactions in real time, simulates outcomes in a sandboxed environment, and blocks phishing sites, honeypots, wallet drainers, address-poisoning attacks, and other malicious smart-contract patterns before users sign. The extension is complemented by a MetaMask Snap (verified and listed in the official Snaps Directory after a Veridise audit), a web-based Dashboard for wallet health and token-approval management, a Telegram Mini App, and a W3A API for enterprise integrations. Supporting services include live monitoring dashboards for address poisoning, wallet draining, and Twitter phishing scams, which feed threat intelligence back into the detection engine.
The company operates a product-led, freemium go-to-market model: the consumer extension is free, while monetization is layered through a Business API targeting wallets, exchanges, dApps, and government agencies (with named integrations including MetaMask, 1inch, OpenSea, Etherscan, SushiSwap, DeBank, WalletConnect, and Changelly) and an announced premium subscription for power users. Distribution is primarily self-serve via browser stores, the MetaMask Snaps Directory, and the Telegram Mini App, with direct sales for enterprise and government deployments. The company claims 100,000+ users, 50,000+ browser installations, 5,000+ MetaMask Snap users, 60M+ contracts reviewed, 1.5M+ dangerous contracts detected, 144.9M+ websites blocklisted, and 375M+ poisoning attacks identified. No external funding rounds, revenue figures, or institutional investors have been disclosed in the available material.
