Anatomy of the scam
Liquidity-mining scams are a wallet-drainer variant of the pig-butchering playbook. A "mentor" from WhatsApp, Telegram, or a dating-app contact introduces you to a "DeFi yield platform" promising spectacular returns. To participate, you connect your wallet via WalletConnect.
The smart contract you sign authorizes the platform to move tokens from your wallet. You see a "balance" growing — sometimes 8% daily — that is purely a display value on the platform's site. When you try to withdraw, you discover the wallet is empty or being slowly drained.
This is one of the highest-loss crypto scam patterns, often pulling six and seven figures per victim, because the introducer builds trust over weeks before the wallet connection.
Red flags
- A stranger or "mentor" introduces you to the platform.
- Returns are advertised as guaranteed and unusually high (5-15% daily).
- The platform isn't listed on DefiLlama, CoinGecko's DEX tracker, or any major DeFi index.
- WalletConnect prompts a "SetApprovalForAll" or "Permit" signature.
- Withdrawals require an "unlock fee," "tax pre-payment," or new deposit to "verify activity."
- The platform's smart contract isn't published on a major chain explorer, or is recently deployed.
- Customer support is only via Telegram or WhatsApp.
How to verify safely
- Real DeFi protocols are open-source and listed on DefiLlama. Check there first.
- Read every WalletConnect signature. "SetApprovalForAll" gives the contract unlimited authority over your tokens. Treat it as draining your wallet.
- Real yields in DeFi are 2-12% APY, not 8% daily. Anything higher implies extreme risk or fraud.
- Use a hardware wallet that displays contract details. Hardware wallets force you to read each transaction.
- Apply the rule: anyone introducing you to a "guaranteed-yield" platform is the scam, regardless of how nice they've been.
If you connected
- Move remaining funds immediately to a fresh wallet.
- Revoke approvals at revoke.cash. Do not delay.
- Report the contract to chain-analytics services.
- Capture transaction hashes, the platform URL, the contact's profile, all chat history.
- Report to IC3 with full details. Significant losses may be referred to the FBI Virtual Asset Unit.
- Expect a recovery scam DM. Block proactively.
What not to do
- Do not approve "unlimited" allowances. Finite approval is always safer.
- Do not add more funds to "increase yield" after the first.
- Do not pay any "unlock fee," "tax," or "verification deposit" to withdraw.
- Do not trust the "balance growing" display. It's just a number on a webpage.
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.
