Anatomy of the scam
A scammer launches a website that looks like a legitimate DeFi yield aggregator — clean charts, "audited" badges, a copy of Yearn or Aave's UI, a fake TVL counter. They market through influencer payments, paid Telegram channels, and farmed Twitter accounts.
Users deposit stablecoins (USDC, USDT) via a wallet connection. The transaction either:
- Moves the deposit directly to a developer-controlled wallet (the "protocol" never actually deploys yield-bearing contracts), or
- Grants the protocol unlimited approval over the user's tokens, allowing slow drainage.
Some operate for weeks before disappearing; others rug after a single large deposit cluster.
Red flags
- Yields are dramatically above market — 20-50% APY on stablecoins where real protocols pay 3-8%.
- Team is anonymous or "based offshore for regulatory reasons."
- Smart contracts aren't on a real chain explorer, or are deployed by a brand-new wallet.
- "Audited" badge links to a generic image, not a real audit report.
- The protocol promises principal-protected yield, which doesn't exist in real DeFi.
- TVL counter looks suspiciously round or grows on a perfect curve.
- Telegram or Discord admins delete dissenting questions.
How to verify safely
- Check DefiLlama. Real DeFi protocols are tracked there with real on-chain TVL data.
- Verify the audit. Real audit reports are PDFs hosted on the auditor's domain. The auditor (Certik, OpenZeppelin, Trail of Bits, Spearbit) is verifiable independently.
- Look at the smart contract on the chain explorer. Real protocols have detailed contracts with source code verified.
- Search the protocol name + "rug" or "scam" before depositing anything.
- Apply the rule: stablecoin yields above ~8% APY require an extraordinary explanation. None of the explanations are "this new protocol just invented it."
If you already deposited
- Stop adding funds.
- Try withdrawing immediately. Capture the result (often "withdrawal failed: insufficient liquidity").
- Revoke approvals at revoke.cash.
- Report the contract to Chainabuse and ScamSniffer.
- Report to IC3.
- Expect a recovery scam within days.
What not to do
- Do not keep depositing to "average down" or "compound."
- Do not pay any "unlock fee" or "withdrawal tax."
- Do not sign new approvals trying to "fix" the withdrawal.
- Do not connect your hardware wallet to try to verify — the smart contract is the problem, not your wallet.
Where to report
- FTC: reportfraud.ftc.gov — the broadest US fraud intake; reports flow to thousands of law-enforcement agencies.
- FBI IC3: ic3.gov — the right destination when the scam is internet-enabled (phishing, BEC, romance, crypto).
- CFPB: consumerfinance.gov/complaint — for complaints about banks, money transmitters, payment apps, credit cards, debt collection.
- IdentityTheft.gov — if any identity information (SSN, driver's license, account credentials) was shared.
- Your bank or payment platform. Call the number on the back of your card or use the app's in-product help. Time matters — wires can sometimes be recalled within hours; ACH and Zelle are harder but worth trying.
