A device transfer request is a request to transfer an escrow device to a destination account. The request refers to a list of escrow devices to be transferred. When created, the transfer request will be visible to each account, even if the destination account is not a sub-account of the initiating account.
When the device transfer request is accepted by a user on the destination account, devices will be created on that account for each of the escrow devices referred to in the transfer request.
