Many crypto losses do not come from a stolen password or phrase. They come from a single signature you gave without understanding it. This is token approval phishing, and once you see how it works, it is much easier to avoid. Here is the plain version, with no jargon.
Signed something and lost tokens?

What an approval is
On networks like Ethereum, apps cannot touch your tokens unless you give permission. That permission is called an approval. It is useful and normal: a trading site needs approval to swap your tokens. The danger is that an approval can be written to allow far more than you intend.
How the trick works
- You visit a site promoted by an ad, a message or a hacked account.
- It asks you to connect your wallet to claim, mint or verify.
- It presents a signature request that looks routine.
- That request is really an approval to move your tokens.
- Once you sign, the site sweeps the tokens it was allowed to take.
The requests to fear
| Approve or setApprovalForAll | Lets a contract move your tokens or NFTs |
|---|---|
| Permit | An off chain approval that can be used later |
| An unexpected transfer | A claim that is really a send |
| A blind signature | A request you cannot read in plain words |
How to stay safe
⚠ Habits that keep you safe
- Read every signature request before you sign
- Do not sign anything you cannot understand
- Use a wallet that shows what will leave your account
- Keep a small wallet for trying sites and a separate one for savings
- Be suspicious of urgency and surprise claims
If you already signed
- Disconnect the site from your wallet.
- Open a token approval checker on the network explorer, such as Etherscan.
- Revoke any approval you do not recognise.
- Move your remaining assets to a brand new wallet, because some attackers try to act first.
- Save the site address and transaction hashes, then report it.
Why moving wallets is safest
Revoking an approval costs a small network fee, and a fast attacker may try to beat you to it. Moving the remaining assets to a fresh wallet removes the risk entirely. Think of the old wallet as exposed once a bad approval exists.
Can it be traced?
Yes. The attacker’s wallet is public, and funds that reach an exchange can sometimes be frozen after a police report. Report to the FBI Internet Crime Complaint Center (IC3), Action Fraud or your local police, and keep the details.
Did they need my seed phrase?
No. Approval phishing uses the permission you signed, not your phrase.
Is my new wallet safe?
Yes, as long as you do not connect it to the same site or sign unknown approvals.
Why this one catches careful people
Approval phishing works on experienced users too, because signing is a normal part of using web3. The trick hides a dangerous permission inside a routine looking request. Slowing down for two seconds to read what you are signing is the single habit that defeats it. When a well known project suddenly offers a surprise claim with a deadline, check its official channels first.
In a nutshell
- An approval lets an app move your tokens.
- Malicious sites hide a broad approval in a signature.
- Read every request and never sign blind.
- Revoke approvals and move to a new wallet.
