Systems and methods include receiving a physical currency transfer request from a physical currency receiver device of a physical currency receiver, and identifying a physical currency deliverer device of a physical currency deliverer. A physical currency delivery confirmation code is then associated with a recipient identified in the request, and a virtual currency address controlled by the physical currency deliverer and included in a virtual currency public ledger is identified to the receiver device. A reimbursement request code is then received from the deliverer device and verified using the physical currency delivery confirmation code. In response to the verification, a multi-signature transaction that has been previously signed by the physical currency receiver is then signed to cause a virtual currency amount to be transferred via the virtual currency public ledger to the virtual currency address controlled by the physical currency deliverer.
