  • Patent number: 10229451
    Abstract: A method for processing transaction information for a commodity object is provided. The method includes receiving a request for purchasing a commodity object and generating, based on the request, a transaction order. The transaction order may include transaction amount information, information about a first user selling the commodity object, and information about a second user purchasing the commodity object. The method may further include setting an amount of fund in a fund account of the second user to a frozen state, and after a preset time period, transferring the amount of fund to a fund account of the first user. After the amount of fund is set to the frozen state and before the amount of fund is transferred to the fund account of the first user, an income produced by the amount of fund may be calculated and transferred to the fund account of the second user.
