Crypto Scam Checker

Spot the warning signs of crypto scams on a website, in a chat or in a link, before you send any money.

  • Checks run on your device
  • No account
  • No tracking
The extension popup over a fake investment site, showing Critical risk with four warning signs, including promises of guaranteed profits and a website that is only three weeks old.

Three ways to check

Scams follow the same scripts again and again: fake investment sites, "wrong number" chats, "pay a tax to withdraw", giveaways that double your crypto. Crypto Scam Checker knows those scripts.

1

Check this page

Click the icon on any website. You get a clear result, the exact words it found, why they matter, and a button that highlights them on the page.

2

Check a message

Paste a WhatsApp, Telegram, text or email conversation. It looks for the patterns behind investment and romance scams.

3

Check a link

Right-click any link and choose "Check this link". It looks at the address only. The link is never opened.

What it checks

Each warning comes with a level, so you can tell a serious danger from a small sign.

Critical

Asks for your wallet words

Pages or messages that ask for your recovery phrase, seed phrase or private key, including forms with 12 or 24 word boxes.

Critical

"Send 1, get 2 back"

Giveaways that promise to double the crypto you send, and "validate your wallet" pages.

High

Guaranteed profits

"Guaranteed returns", "risk-free", "2% daily" and other fixed profit promises.

High

Pay to withdraw

Being told to pay a fee, tax or deposit before you can take your own money out.

High

Copycat addresses

Web addresses one letter off a well-known crypto site, or brand-new sites offering investments.

High

Fake recovery services

Offers to get back lost or stolen crypto, which often target people a second time.

Medium

Chat app pressure

A "manager" on WhatsApp or Telegram, a "wrong number" opener, a stranger who wants to teach you to trade.

Medium

Rush and big names

Countdown timers, "only today" offers, celebrity and "as seen on" claims, AI bots with profit figures.

Medium

Website age

How long ago the address was registered. Most fake sites are only weeks or months old.

Private by design

The extension does its work inside your browser. The only thing that ever leaves it is a website's name (like example.com), sent to the public registry for that address to look up how old it is.

Read the privacy policy

  • Reads a page only when you click the icon. It does not watch the sites you visit.
  • Never sends page content or pasted messages anywhere.
  • Never opens the links you ask it to check.
  • No accounts, no analytics, no ads, nothing sold.

An honest note: no tool can catch every scam, and scammers change their wording often. "No warning signs found" never means a site is proven safe. Never send money to someone you only know online.

Questions

Does it read my messages?

Only the text you paste into the "A message" tab, and only on your own computer. It cannot see your WhatsApp, Telegram, texts or email on its own.

Nothing you paste is sent anywhere or saved. Close the popup and it is gone.

Why did a real site get a warning?

Warnings describe signs, not proof. A brand-new website, an unusual address ending or a shortened link can appear on honest sites too. On their own these are small signs, and the result says "A few warning signs".

Each warning shows exactly what was found and why it matters, so you can judge it yourself. Pages that teach people about scams are recognised, so the scam phrases they quote are not counted.

What should I do if I already sent money?

Stop sending money, even if you are told a fee or tax will unlock your balance. That is part of the scam.

Contact your bank or the payment service right away. Keep every message, address and receipt. Report it to the FBI's Internet Crime Complaint Center at ic3.gov and to the FTC at reportfraud.ftc.gov.

Be very wary of anyone who contacts you offering to recover your money for a fee. Fake recovery services target people who were just scammed.

Is it free?

Yes. It is free and powered by Crypto Renegades. There is no paid version, no account and no sign-up.

Does it work on my phone?

It works in Chrome on a computer (Windows, Mac, Linux and ChromeOS). Chrome on phones and tablets does not support extensions.

Check before you send

Add it once. Use it whenever a website, message or link makes you unsure.
