P2P Crypto Scams: The Most Common and How to Avoid Them

A well-designed P2P marketplace eliminates the most serious risk, that the seller gets paid and doesn’t deliver, thanks to escrow. But scammers don’t attack the contract: they attack people. These are the most common scams in crypto P2P and how to avoid them, whether you are buying or selling.

1. The fake payment receipt

How it works: the buyer marks the order as paid and sends a screenshot of a bank transfer or a Bizum that was never made (or that was made for a smaller amount). They pressure the seller to hurry and release the crypto.

How to avoid it: as a seller, check the incoming payment in your bank’s app, not in a screenshot. Never release funds based on a receipt, however convincing it looks, and don’t let yourself be rushed: the deadline only works in the buyer’s favor once they have actually paid.

2. Triangulation

How it works: the scammer advertises something (a phone, a rental, an “investment”) to a victim and, at the same time, opens a crypto purchase order with you. They give the victim your payment details, the victim pays you believing they are paying for their purchase, and you release the crypto to the scammer. Days later the victim files a complaint and their bank demands the money… from you.

How to avoid it:

• Accept payments only from accounts in the name of the order holder. If the name doesn’t match, don’t release and open a dispute.
• Be wary of split payments from several accounts.
• If a payment arrives with a strange reference (for example, the name of a product you don’t sell), stop.

3. Chargebacks

How it works: the buyer pays using a reversible method, receives the crypto, and then files a claim with their payment provider alleging an unauthorized charge or a product not received.

How to avoid it: payment methods with buyer protection, such as card payments or some PayPal payments, are the most exposed. If you are selling, prefer methods that cannot be charged back, such as SEPA transfer or Bizum, and check the buyer’s reputation before accepting large amounts through reversible methods.

4. Moving the conversation off the platform

How it works: the other party suggests continuing on WhatsApp or Telegram, “because it’s faster,” or closing the deal outside escrow to “save on fees.”

How to avoid it: never do it. Outside the order there is no escrow protecting your funds, and no conversation that can serve as evidence in a dispute. On Vailox, the order chat lets you send payment proof precisely so that everything stays inside the process.

5. Fake support

How it works: someone pretending to be the platform’s team messages you on social media or in a Telegram group. They offer help with a frozen order and end up asking for your seed phrase, for you to sign a transaction, or to install an app.

How to avoid it: real support will never ask for your seed phrase or private key and will not message you first in private. If you have a problem with an order, open a dispute from the order itself.

6. Cloned sites and wallet drainers

How it works: a site identical to the platform’s, with an almost identical address or advertised in search engines, asks you to connect your wallet and sign a transaction that actually authorizes emptying it. Sometimes it isn’t even a clone: in 2025 the P2P platform Paydece suffered a domain hijacking that pointed to a site draining every wallet that connected to it, until the team recovered the domain.

How to avoid it:

• Always enter from a saved bookmark, not from ads or links in messages.
• Read what you sign. An unlimited token approval to an address you don’t know is a red flag.
• Review and revoke your wallet’s token approvals from time to time.
• If you hold large amounts, use a cold wallet and a separate wallet for trading.

7. Network errors (not a scam, but they cost just as much)

How it works: you send or request USDT on one network while the other party expects it on another. The funds arrive, but at an address or on a network that the other party doesn’t control or can’t see.

How to avoid it: on a P2P with onchain escrow, the network is locked in the order, which eliminates most of these errors. If you later move your funds, always check that the source and destination networks match. We explain this in which network to choose.

Quick checklist before each trade

If you’re buying:

• The crypto is locked in escrow before you pay.
• You pay from an account in your name and for the exact amount.
• Everything happens inside the order chat.

If you’re selling:

• You check the payment in your bank, not in a screenshot.
• The payer’s name matches the buyer’s.
• You don’t release in a hurry or under pressure.

The general rule is simple: if someone asks you to leave the order’s normal process, it’s a red flag. P2P platforms with escrow, such as Vailox, are designed so that you don’t have to trust the other party. Scams almost always start when someone convinces you to stop using those protections.
