All transactions reached in the exchange will eventually be sent to the clearing house, which will be settled by the exchange. The clearing house for valet payment acts as a third-party guarantor for the buyers and sellers of transactions, that is to say, all transactions reached in the exchange will eventually be sent to the clearing house for unified settlement by the exchange. In this way, the buyers and sellers of any transaction no longer have any relationship with each other, and they no longer bear financial responsibilities for each other, but are only indirectly responsible for the transaction settlement through their respective clearing house member companies.
