Use Address Checker to protect your searches from Crypto scams.

Change your default search to avoid falling for crypto scams. Address Checker by Securify recognizes thousands of known bad Bitcoin addresses and will warn you when you search for one on the web. As a rule, before sending funds to addresses, you should always check them in the extension's pop-up. If an address is known to be bad, a (huge) warning will be displayed however if the address is not detected it does not necessarily mean it is safe. Always search for the address and let Address Checker make sure it's not a known bad address. Demo: - Type a known bad bitcoin Address "3Fb8pztJQS5vwn9wASMYLfjs1CdBu3TgtC" in the search bar. When a bad address appears, you will be redirected to a crypto scam database to inspect the history of that address Feel free to contact the support team at [email protected]
