The introduction of the multi-policy model in Marmalade V2, with the inclusion of middleware contracts like policy-manager and sale-contracts, aims to enhance the user experience by simplifying token creation and management.

quoted price from the buyer to an escrow account, disburses a portion of the
reserved fees to the policies, and then remits the remaining quoted price to the
