System and method for facilitating secure transactions

A system for secured electronic transaction execution, the system comprising:

• a secured memory device configured to store validation codes indexed by identifiers for respective transactions;
• one or more processing devices;
• and
• a non-transitory computer readable medium storing instructions executable by the one or more processing devices, wherein the instructions, when executed by the one or more processing devices, cause the system to:
• receive, from a client device via a communications network, electronic transaction information for a transaction, wherein the electronic transaction information identifies a third-party agent associated with the transaction;
• transmit, to a device of the third-party agent, a request for a transaction instruction for processing of the transaction by a processing device, wherein the request for the transaction instruction includes at least a portion of the electronic transaction information;
• receive, from the device of the third-party agent, the transaction instruction for the transaction;
• after receipt of the transaction instruction, generate a validation code based at least in part on the transaction instruction;
• store, in a secured memory location of the secured memory device, the validation code;
• transmit, to the client device via the communications network, a request for authenticating the transaction instruction;
• receive, from the client device, the validation code;
• and
• cause transmission of the transaction instruction to the processing device.
