After a trade request is confirmed, seller’s cryptos are locked in an Escrow wallet (owned by Koinex). Cryptos are not released until seller confirms the receipt of the payment made by the buyer. Seller needs to double confirm by clicking ‘Received’ button and entering Authenticator OTP to proceed. Only after this, the funds are transferred to buyer’s wallet. Also, we take necessary documents from the buyer as a proof of payment in order to verify the transaction.
