Scam Guide

Don't get drained.

Most crypto losses from scams don't need any hacking. The victim signs something. Here's how the common scams work and the habits that stop them.

The three golden rules

  1. Never share your seed phrase or private key. Not with "support", not with a "wallet validator", not with anyone. No legitimate service needs it.
  2. Read what you sign. If your wallet asks for an approval, permit or "setApprovalForAll" you didn't expect: reject it.
  3. Assume every DM is a scam. Real projects and real support don't DM you first. Neither does iShowMoney.

Common scams and how they work

Fake airdrop / claim sites

A lookalike domain (extra letter, different TLD, "claim-" prefix) promoted via replies, ads or hacked accounts. "Connect wallet to claim" then asks for signatures that hand over your tokens.

Defense: only use links from the project's official website/docs that you navigated to yourself. Bookmark them. Be extra careful with sponsored search results.

Wallet drainers & approval phishing

Malicious sites request token approvals (approve, increaseAllowance, setApprovalForAll) or off-chain signatures (Permit/Permit2, Seaport orders). One signature can let the attacker move assets later.

Defense: read the signing request; reject unlimited approvals; use a wallet with transaction simulation; revoke old approvals regularly (e.g. revoke.cash or the explorer's token-approval tool).

Address poisoning

Scammers send you a tiny or zero-value transfer from an address that looks like one you use (same first and last characters), hoping you copy it from your history next time.

Defense: never copy addresses from transaction history. Use an address book, verify the full address, send a test amount first for large transfers.

Impersonation & fake support

Fake accounts copy a project's or influencer's name and avatar and reply "DM us for help" or "claim here". Fake support in Discord/Telegram asks you to "sync" or "validate" your wallet.

Defense: check the exact handle, account age and who follows it. Support never DMs first and never needs your seed phrase.

Pig-butchering & "investment" friends

A friendly stranger (dating app, wrong-number text, social media) builds trust for weeks, then introduces a "trading platform" that shows fake profits. Withdrawals are blocked by "taxes" or "fees".

Defense: never invest through a platform someone you only know online recommends. If you can't withdraw a small amount freely, stop depositing.

Rug pulls & honeypot tokens

New tokens where the team can mint, block selling, or pull liquidity. Honeypots let you buy but not sell. Often pushed by paid, undisclosed promotions.

Defense: check contract ownership, liquidity lock and holder concentration; test a small sell; be skeptical of anything shilled with countdowns and "guaranteed" gains.

Malicious files & fake apps

"Beta tester" invitations, fake job offers or cracked tools ship malware that steals wallet files and browser sessions. Fake wallet apps in app stores and ads steal seed phrases on setup.

Defense: install wallets only from the official site; don't run files from strangers; use a separate device or browser profile for crypto.

Recovery scams

After you've been scammed, "recovery experts" or "blockchain lawyers" promise to get your funds back for an upfront fee.

Defense: nobody can reverse blockchain transactions for a fee. Report to the police and the exchange that received the funds instead.

Checklist before you connect or sign

A simple wallet setup

  • Vault wallet (hardware wallet) for long-term holdings; it never connects to new dApps.
  • Hot wallet(s) for trying new apps, funded with only what's needed.
  • Separate browser profile for crypto, few extensions.
  • Regularly review and revoke token approvals.
  • Seed phrases offline only. Never in a screenshot, cloud note or password field on a website.

If you think you've been hit

  1. Move remaining assets from the affected wallet to a new wallet with a new seed phrase.
  2. Revoke approvals from a clean device.
  3. If the seed phrase leaked, treat the wallet as permanently compromised.
  4. Document transaction hashes, addresses and screenshots.
  5. Report to local police and to any exchange that received the stolen funds (they can sometimes freeze them).
  6. Ignore anyone offering paid "recovery".
