The short answer
A liquidity-mining invitation can be a route to malicious token permissions or a fake investment balance. Connecting a wallet and approving spending are distinct actions; a convincing yield display does not prove that your assets are safe.
The invitation often starts with a relationship
Someone met through messaging, dating or social media may offer to teach you a low-risk way to earn income from stablecoins. They may emphasise that the assets stay in your own wallet, making the arrangement seem safer than sending a deposit.
That reassurance can obscure the permission requested by a smart contract. Assets appearing in your wallet can still be exposed if a spender has an allowance that lets it transfer them.
Read the permission, not just the website
The FBI has described liquidity-mining schemes in which victims are induced to connect wallets and grant permissions. A request described as joining a pool, obtaining a voucher or activating a node may authorise spending.
Do not assume a tiny initial fee means the risk is tiny. The fee and the permission are different. A contract allowance can have a much larger scope than the visible payment used to set it up.
Displayed yield may not be withdrawable value
A site can show daily returns without holding assets corresponding to them. Small early payments can encourage larger balances or broader approvals. Later, the operator may claim you need a deposit to meet a pool threshold or release frozen funds.
Record what actually entered and left wallets you control. Keep claimed yield separate from verified receipts and do not add funds solely because a website says a target is almost reached.
If you already interacted
Stop signing new requests. Save the domain, messages, transaction hashes and permission details. Review allowances using official wallet guidance reached independently; disconnecting the website alone does not revoke an on-chain allowance.
If you entered recovery words, treat that as key compromise rather than an approval-only problem. Revoking permissions cannot secure keys someone else can use. Avoid rescue tools sent by the person who introduced the investment.
Report the mechanism clearly
Explain whether you transferred funds voluntarily, approved a contract or disclosed signing credentials. These details help a provider or investigator understand the incident rather than treating every loss as an ordinary withdrawal.
Legitimate decentralised finance also carries contract, liquidity and market risk. The existence of genuine products does not validate a stranger's offer, guaranteed returns or a claim that regulatory registration makes a smart contract risk-free.
Checklist
- Stop approving transactions on the suspect site.
- Save contract and transaction details.
- Review allowances through verified wallet documentation.
- Report real losses separately from displayed yield.
Common questions
Are funds safe if they remain visible in my wallet?
Not necessarily. A granted allowance may let a contract spend tokens even while they are still displayed in the wallet.
Does every liquidity pool mean fraud?
No. This guide concerns deceptive invitations and permissions. Genuine products can still involve substantial technical and financial risk.
