A secure referral transfer includes receiving an offer for a connection agreement from a source, with the connection agreement defining data objects to be shared in transactions between the source and a target; receiving an acceptance of the offered connection agreement from the target; facilitating a connection between the source and the target based on the accepted connection agreement; and connecting a channel endpoint for the source and a channel endpoint for the target to facilitate a transaction. The secure referral transfer may be implemented without a direct integration of the infrastructure of the source and the target.
