A few days ago, a reader messaged me saying they received a notice claiming their crypto wallet was "frozen for risk control", and they had to transfer a sum of "unlock fee" to a specified address to reactivate it. They asked me if this notice was legitimate.

My answer is straightforward: Do not trust it. This is a classic fraud routine adapted from traditional financial scams to the crypto space. It only changes its packaging, and the core trick remains exactly the same.
4 Most Suspicious Red Flags in This Type of Notice
Red Flag 1: Decentralized wallets do not have a "freeze" function at all
A crypto wallet is only a tool to manage your private key. Your digital assets are stored on the blockchain, not inside the wallet app. No one can "freeze" your decentralized wallet, unless you have handed over your private key or seed phrase to others.
Formal crypto platforms will never threaten to freeze your assets to force you to pay. If someone claiming to be customer support says your wallet is frozen and asks you for an unlock fee, treat it as a scam immediately.
Red Flag 2: The "unlock fee" only goes in and never comes back, it is essentially a trick to make you transfer money voluntarily
The core of this scam works like this: You get a notice saying your account is frozen, and you need to send a "security deposit" or "unlock fee" to a specified address to restore access. After you make the transfer, the scammer will claim "you made a wrong operation" or "the account is locked again" to ask you to send more money.
Note this is not a technical hack, it is purely a trick to get you to send your crypto to the scammer on your own. Blockchain transactions are irreversible, once confirmed, no one can get your funds back.
Red Flag 3: It creates panic to leave you no time to think
"Your account has been urgently frozen due to abnormal activity. Please pay the unlock fee within 2 hours, or your assets will be permanently frozen."
This is one of the most classic scammer lines: create a strong sense of urgency. When people are panicked, they skip logical checks and follow the scammer's instructions directly. Any notice that uses "limited time", "act now" or "permanent freeze otherwise" to push you to transfer money is a scam.
Red Flag 4: It asks you to send funds to a so-called "safe account" or "special unlock address"
This is the most obvious flaw. If a legitimate exchange really restricts your account for compliance reasons, it will ask you to submit KYC documents and complete facial verification, it will never ask you to transfer money to a third-party address. Even law enforcement agencies will never ask you to transfer funds to a "safe account" via private message or phone call.

The Only Correct Action to Take When You Receive This Type of Notice
Your goal: Confirm the real status of your account, and cut off the scam path.
How to do it: Close that suspicious notice immediately. Do not click any links inside it. If you use a decentralized wallet, open your official wallet app to check if your balance and transaction history are normal – if everything looks right, your wallet is not frozen at all. If you use an exchange, open its official app, go to the "Security Center" or "Help Center" to check your account status, or contact the official online customer support to confirm.
Validation for correct operation: You check on the official platform and confirm your account is fully normal, there is no such "freeze" alert at all.
Risk Reminder: A common variant of this scam is: fake customer support asks you to share your screen, then claims you made a wrong operation that caused the account to freeze, and you need to pay an unlock fee. Any request to share your screen, or ask you to send crypto to a specified address to "unlock" your account is fraud. No legitimate platform has a paid "unlock fee" service.
How to confirm you did it right: Verify your account status and asset balance show no abnormal changes in the official app. If you have any doubt, contact support only through official channels (the in-app online support, not phone numbers you find via search engines).
Next recommended step: Save the official apps of your commonly used exchanges and wallets to your phone home screen, and bookmark their official websites in your browser. Whenever you receive any notice asking you to make operations, always verify through these official entry points first, never click links from the notice directly.
