If you need to message the seller for any reason, tap the highlighted icon.

If not, check the order details and tap Continue.

  1. How to solve a dispute on the OKX P2P marketplace

When buying crypto via P2P trading, you can raise a dispute if you've made a payment but the seller did not release the crypto. Before doing so, we recommend you to:

  • Give some time for the seller to release the tokens
  • Communicate with them. There are sometimes bank transfer delays, especially if you've used a non-instantaneous payment method.

In the meantime, OKX will also automatically send an email to the seller, reminding them to release the crypto.

If the issue persists, you can raise a dispute by:

  • Locating your relevant order in the My Orders section
  • Tapping the Dispute button

Once a dispute has been raised, our Customer Support team will act as a mediator between you and the seller and will follow up accordingly with the respective parties.

P2P trading disputes

  1. P2P marketplace cancelation rules

If you’re buying crypto with local currency on our P2P Trading marketplace, you can cancel the trade at any time. This releases the assets held by OKX back to the seller. Your order will be canceled if you don’t make the payment on time. You mustn’t attempt to send payment close to expiry because the funds are returned to the seller automatically if the time runs out before you mark the payment as completed. It’s safer to cancel the order and start again. To cancel an order, locate your relevant order in the My Orders section and tap Cancel.

When buying on the P2P marketplace, we recommend you never cancel an order that has been paid. Instead, you should reach out to the seller to come to an agreement on the refund before cancelling.
