About Wallet Guard

It provided human-readable transaction details, phishing detection for sites mimicking legitimate websites, and warnings with risk factors during transactions. The service was sunset as of March 31, 2025 and is no longer available. It was not a wallet and was intended to be used alongside a user's wallet of choice.
