FAQ

Extension questions

New to wallet security? Start with how to spot crypto phishing sites.

Is GuardSmith Shield a free crypto scam checker?
Yes. It's free, with no account, analytics or tracking. It checks sites against the MetaMask eth-phishing-detect and ScamSniffer lists locally in your browser, and checks wallet addresses and token contracts against GoPlus risk data when you ask it to.
Does it send the sites I visit anywhere?
No. The phishing lists are downloaded about every 12 hours and every site check happens on your device. Only an address you choose to check is sent to GoPlus. See the privacy policy.
Which browsers are supported?
Chrome, Edge and other Chromium browsers, and Firefox. Store listings are in review; the links will be added to this page once each store approves them.
Does PulseWatch need my wallet?
No. It shows prices, alerts and gas from public APIs. The optional swap buttons open ChainHop or Solswift, where swaps include a disclosed 1% fee.
