Abstract: An apparatus for secure decentralized rebate management is presented. The apparatus includes at least a processor and a memory containing instructions configuring the at least a processor to receive a claim process request including a plurality of elements of a user data and generate a claim initial entry comprising a conditional claim trigger configured to deploy on an immutable sequential listing. The at least a processor is further configured to execute a claim mapping function including the at least a processor to generate a conditional rebate array including a plurality of rebate requirements, match each rebate requirement to each element of the user data, deploy a plurality of claim test entries representing matches on a private layer, and determine a claim mapping result. The at least a processor is configured to generate a claim result entry configured to deploy on the immutable sequential listing and execute the conditional claim trigger.
