Publication number: 20230410110Abstract: Systems and methods are provided for leveraging different data repositories. One example computer-implemented method includes receiving a transfer request for a transfer from a sender in a first region to a recipient in a second region and determining whether the transfer request satisfies a regulation associated with the first and/or second region for information related to the recipient and/or sender. The method also includes submitting an identity request for the recipient and/or sender to an identity network, in response to the transfer request failing to satisfy the regulation, and receiving information regarding the recipient and/or sender, in response to the identity request, from the identity network, where the information includes identifying information for the recipient and/or sender. The method then includes compiling and submitting a transfer request for the transfer to an associated network, whereby the transfer request is submitted to be completed.Type: ApplicationFiled: May 19, 2023Publication date: December 21, 2023Inventors: Rajat Maheshwari, Matthew Selkirk Driver, Karthik Ramanathan, Nimit Gulati
