How does the crypto scam checker work?

Paste a message, URL, or offer into the tool. It scans the text for crypto-specific red flags: seed-phrase requests, guaranteed-return promises, urgency language, impersonation of support staff, and eight other patterns, and returns a risk score. The check runs entirely in your browser and nothing is uploaded.

Is the scam checker private?

Yes. All analysis happens client-side in your browser. The text you paste never leaves your device and is not sent to any server.

What are the most common crypto scam red flags?

Requests for your seed phrase or private key, guaranteed or unrealistically high returns, urgency or "act now" pressure, unsolicited DMs claiming to be support, and links to fake exchanges or wallets. The tool flags all of these patterns automatically.

Specification & Methodology

Understanding your results.

A rigorous breakdown of the mathematical equations, market assumptions, and step-by-step calculations powering this tool.

The tool analyzes your input against a database of known scam patterns and returns a risk score and a list of specific red flags detected. The evaluation checks:

URL patterns - known phishing domains, lookalike domains (e.g., "coinbbase.com" with two b's), and suspicious TLDs
Message patterns - urgency language, seed phrase requests, guaranteed return promises, impersonation phrases
Contract addresses - against known honeypot and scam token databases

The verdict is one of: Safe, Suspicious, or Scam. Each red flag is explained so you understand why it triggered.

Important: this is a heuristic classifier, not a guarantee. Always use your own judgment and verify through independent channels.

Operational Guide

How to use this tool.

Step-by-step workflow instructions to get the most accurate calculations for your trading strategy.

Paste the URL, contract address, or message you want checked. The tool inspects the input against a database of known scam patterns and surfaces a verdict in under a second.

The checker looks at 50+ signals, including: known phishing domain lists, scam pattern matching in URLs, and contract addresses reported to scam databases. If a URL points to a token contract, it will check that contract's source for known honeypot patterns.

Pro tip: always verify the URL yourself by reading the domain character by character. Scammers register coinbbase (with two b's) all the time. The checker catches those, but you should train your eye too.

Privacy & safety.

Your privacy matters. This checker runs entirely in your browser. The text, URL, or contract address you paste is never sent to any server - all pattern matching happens locally.

Not legal or financial advice. This tool is a heuristic classifier designed to flag common scam patterns. It is not a guarantee of safety. Always verify suspicious messages, URLs, and offers through independent channels. If you believe you have been defrauded, contact local law enforcement.

Never paste active wallet credentials. Do not paste a seed phrase, private key, or password that you currently use into any online tool - including this one. If you want to test a seed phrase, use one generated specifically for testing.

Safety & alternatives.

Avoid these mistakes

Scammers use urgency. "Limited time offer" and "Act now" are designed to bypass your critical thinking. Always pause and verify through independent channels.
Never connect your wallet to unknown dApps. Many scams involve fake dApps that drain your wallet after you grant token approval.

If you prefer to trade on verified platforms

Stick to reputable exchanges with proven security track records. Use our Swap Fee Comparator to find the best rates on verified platforms. For long-term storage, use a hardware wallet like Ledger - never store significant funds on an exchange.
