Making Web3 safe for everyone, one blocked scam at a time.
Web3 is full of innovation, but it's also a dark forest. Millions of dollars are lost every month to sophisticated wallet drainers, fake airdrops, and homograph phishing attacks. Traditional antiviruses don't understand smart contracts, leaving MetaMask users vulnerable.
We built MetaMask Defender because we were tired of seeing the community get rekt. Our team of Web3 security researchers analyzed the exact methods scammers use—from MaxUint256 approvals to Seaport blind-signing exploits—and built a bot that detects them in real-time.
Security shouldn't cost you your privacy. MetaMask Defender runs locally in your browser. We do not track your IP, we do not log your wallet addresses, and we do not sell your browsing data. The code executes on your machine to protect your machine.
