Abstract: An interaction and resource exchange system that provides authentication for a designated user to complete an interaction entered into by an initiating user. An initiating user is able to enter into interactions with third-parties and set one or more interaction limits and/or designated user requirements to allow a designated user to complete the interaction with the third-party should interaction limits and/or designated user requirements be met. The interaction limits and/or the designated user requirements allow for improved security related to these types of interactions and resource exchanges. In particular, the interaction and resource exchange may be implemented through a real-time resource exchange network that efficiently allows for the designated user to complete the interaction.

Abstract: Some embodiments provide a method for evaluating a policy for authorizing an API (Application Programming Interface) call to an application. Based on a first set of parameters available before receiving the API call, the method evaluates only a portion of the policy to produce a partially evaluated policy. The method stores the partially evaluated policy in a cache. The method then receives an API call to authorize, and determines whether the API call should be authorized by fully evaluating the policy, using the partially evaluated policy retrieved from the cache first storage, and a second set of parameters associated with the API call. The method responds to the API call with a policy decision based on the fully evaluated authorization policy.

Abstract: A transaction processing system is configured to receive a transaction request to execute a transaction at one or more of a plurality of third party systems. The transaction processing system accesses an adjusted transaction record storing a plurality of open transactions received from the plurality of third party systems. The transaction processing system further divides the transaction request into one or more split transaction requests. The one or more split transactions requests are sent to a corresponding third party system for execution. The corresponding third party system executes the open transaction corresponding to each split transaction at the requested unit count of each split transaction. In response, the transaction processing system receives an execution report from one or more of the plurality of third party systems.

Abstract: A computer implemented method for creating and matching implied inter-commodity spread orders where a spread ratio between legs of the inter-commodity spread is endogenous. The implied spread price is determined with a multi-step calculation including determining the price ratio between the underlying products and balancing the quantity of contracts required of each leg product.

Abstract: Systems and methods for managing cryptocurrency systems.

Abstract: A system can include one or more processors and non-transitory computer-readable media storing computing instructions configured to run on the one or more processors and perform a method for automatically processing an online return request. The method performed by the system can receive a refund request from a user computer used by a customer of a grocery store, the refund request for returning a grocery item (a) previously purchased as part of a transaction of the grocery store and (b) paid for by a payment method via the transaction; and process a refund solution based on the transaction and the grocery item. In this system, the method can process the refund solution by determining a returnable status of the grocery item according to one or more returnability rules dynamically generated by a machine learning model. If the returnable status of the grocery item is negative, the method performed by this system can deny the return request.

Abstract: A hardware wallet and a hardware wallet holder identity verification method, relating to the field of digital currency. The hardware wallet comprises a virtual machine, a biological characteristic authentication module, and multiple wallet applications. Each wallet application stores a private key. The hardware wallet records, for each wallet application, a biological characteristic for verifying hardware wallet holder identity corresponding to each wallet application by using the virtual machine and the biological characteristic authentication module. Private key pair digital currency in the current wallet application can be used for trading only when verification of the hardware wallet holder identity corresponding to the current wallet application succeeds. The digital currency security protection mechanism is improved, and identity authentication management of multiple wallet applications is realized.
