Abstract: In order to produce fractional digital assets, systems and methods include displaying a digital assets bundle ordering graphical user interface. Receiving user-specific bundle data including digital assets. Allocating a notional purchase amount among the digital assets based on an allocation. Determining, from external marketplaces, numbers of whole ownership units of each digital asset based on the notional purchase amount allocated to each digital asset. Electronically executing purchases of each number of whole ownership units of each digital asset to store in firm account data in a firm account of an asset-tracking database. Determining a user-specific ownership fraction in each number of whole ownership units based on the notional purchase amount allocated to each digital asset. Generating an allocation link between each firm account data of the whole ownership units and user-account data of each user-specific ownership fraction.

Abstract: Disclosed is roof panel construction, preferably of galvanized steel, aluminum, fiberglass reinforced plastic, and the like, comprising a substantially flat body of substantially parallelogrammatic configuration, first shoulder means adjacent a first edge of said body and extending substantially in a straight line across said body, said shoulder means extending outwardly from the plane of said body a distance approximately required to accomodate the thickness of an adjacent shoulder means, and then for a short distance away from said edge in a plane substantially parallel to the plane of said body to provide an opening, said shoulder means and said edge being spaced sufficiently along the plane of said body to provide an attachment tab, said shoulder means and said body being hermetically sealed at their juncture, and a second edge of said body substantially oppositely disposed to said first edge and provided with second shoulder means of essentially the same configuration as said first shoulder means but opp
