Love the wallet lookup feature. Checked a suspicious address and it was flagged for money laundering. Avoided a scam!

What the Web3 community says about ChainGuard

ChainGuard caught a phishing site that my browser didn't flag. The security score feature gives me confidence before I connect my wallet.

The wallet lookup feature is incredible. I checked an address from a suspicious DM and it was flagged for cybercrime. Saved my ETH.

As a Web3 developer, I appreciate the technical depth. The DOM analysis catches things I would have missed during testing.

Privacy-first and no accounts required. Finally a security tool that respects user data. Running it on all my browsers.

The token contract checker found a honeypot I almost bought. ChainGuard is now essential for my trading workflow.
