P2P crypto trading: how escrow works and how to stay safe

How a P2P trade works

In peer-to-peer (P2P) trading you buy or sell crypto — very often a stablecoin such as USDT — directly with another person, and the money moves between the two of you by bank transfer, mobile money or another local method. On an exchange’s P2P marketplace the steps are designed like this:

1. The seller posts an offer: price, limits and accepted payment methods.
2. When a buyer opens an order, the exchange locks the seller’s crypto in escrow, so the seller cannot spend it elsewhere during the trade.
3. The buyer pays the seller outside the exchange, within the time limit of the order, and marks it as paid.
4. The seller checks that the money has arrived and releases the crypto, which the exchange moves to the buyer’s account.
5. If they disagree, either side can open a dispute and the exchange’s staff decide, based on the evidence both sides give.

Read the P2P rules of the exchange you use: time limits, accepted payment methods, whether the payment must come from an account in the buyer’s own name, and how disputes work all vary.

What escrow protects — and what it does not

Escrow protects the buyer against a seller who takes the money and never releases the crypto. It does much less for the seller, because the payment happens outside the exchange, where the exchange cannot see it. Once the seller releases, the crypto is gone: Canada’s Financial Consumer Agency (FCAC) notes that crypto transactions “are not reversible once verified and confirmed on the blockchain”, which means you may not be able to “get your crypto assets back unless the seller agrees to return it”.

That leaves three gaps:

• A payment that never arrived. A screenshot, a text message or an email saying “paid” proves nothing. Only money that shows in your own bank or mobile-money account, checked in your own app, counts.
• A payment that can be pulled back. If the payer’s bank or payment app can later reverse or recall the money, you can lose both the money and the crypto you released.
• A payment from the wrong person. Money from a third party’s account — not the buyer you are trading with — may be the proceeds of a crime.

When P2P becomes money laundering

Police in Singapore have charged P2P traders on both sides of such trades. In a May 2025 release, the Singapore Police Force (SPF) said a woman would be charged “for allegedly receiving $20,000 in her bank account for a Peer-to-Peer sale transaction in cryptocurrency and failing to take reasonable steps to ascertain the source of the money”; the funds were traced to a scam victim. A man would be charged for “transferring cryptocurrency valued at least $96,000 to a cryptocurrency wallet pursuant to a Peer-to-Peer sale transaction, without taking reasonable steps to ascertain the identity and physical location of the counterparty.”

The offence, the SPF said, “carries a fine not exceeding $50,000 or imprisonment for a term not exceeding three years, or both”, and “Anyone who allows their personal bank accounts or cryptocurrency accounts to be used to receive and transfer money or cryptocurrency for others will be held accountable if these transactions are linked to crimes.” Laws differ by country; find out what yours says before you trade.

The National Bank of Slovakia describes how criminals recruit money mules for this: a stranger sends money to your bank account, you move it to a crypto account opened in your own name, and the stranger uses that account. The central bank is clear that whoever takes part commits a criminal offence, and that “Ignorance of the law is no excuse”. Its warning signs include being approached by a stranger offering quick and easy money, and “Being asked to forward large sums of money through your personal bank account.”

Other tricks to expect

• Payment links. In another SPF advisory, scammers posing as buyers sent “a phishing link to the victims under the pretext of arranging for payment or the delivery of the items”, then used the victims’ bank card details. Never enter banking details on a link a counterparty sends you.
• Fake support staff. Keep every message inside the exchange’s order chat. Scammers pretend to be the platform; the SPF reminds users that licensed crypto platforms in Singapore “will never instruct users to transfer their virtual assets to another crypto wallet/account for security or investigation purposes”.
• Trades outside any platform. Without escrow, nobody holds the crypto during the trade. If you receive crypto directly, the FCAC advises waiting for network confirmation: “It may take 10 minutes or more to receive the confirmation. If you don’t wait, someone may stop the transaction and you could lose your funds.”

Checks before every P2P trade

If you sell crypto:

1. Release only after the full amount is in your own account, checked in your bank or mobile-money app — never on a screenshot or message.
2. Accept money only from an account in the name of the verified buyer on the order; if a third party pays, do not release, and use the exchange’s dispute or cancellation process instead of sending money back on your own.
3. Prefer payment methods the payer cannot easily reverse, and keep records of every trade.

If you buy crypto:

1. Pay only to the account shown in the order, in your own name, and mark the order as paid only after you really paid.
2. Do not accept requests to pay extra “fees” or to move the deal outside the platform.

Always:

1. Trade only on the exchange’s own P2P marketplace, with counterparties who have passed its identity checks.
2. Never let anyone else use your bank, mobile-money or exchange account.
3. Check the token and the network before any transfer.
