When you sell crypto, the asymmetry is the whole risk: your crypto transfer is final, but some fiat payments are not. If the buyer can reverse the payment after you released, you lose both. That is why the single most important property of a payment method, for a seller, is whether the payer can pull the money back.
Three levels of reversal risk
What iEscrow does with this
The marketplace only offers low- and medium-risk rails, chosen per country by iEscrow (one bank transfer per country, PIX, and similar). PayPal, Venmo, Cash App, Skrill and Neteller are not available: not as a warning, as a policy. You cannot list an offer with them, so no buyer can push you into one.
It also fixes who pays: the holder of a payment account is always the account's owner, set by the platform (the document-verified name once identity is verified), so a payment from a third party's account, which is how stolen funds get laundered through sellers, is a red flag you can see and refuse.
If a payment was reversed after you already released
Be clear about this: iEscrow cannot undo a crypto release, and no escrow can make a bank un-reverse a payment. What you can do is collect the trade record (counterparty identity, declared payment, confirmation) and bring it to your bank's fraud desk and, if needed, to a police report. The way to never be there is the rail you accepted in the first place.
