When trade happens between dimensions with different basic physics, what specific economic method is used to keep money's value steady and fair?

When trade occurs between dimensions with differing basic physics, the specific economic method used to maintain money's value as steady and fair is the establishment and active management of a Synthetic Commodity Standard (SCS) by a Central Interdimensional Monetary Authority (CIMA). This method directly addresses the challenge posed by varying fundamental laws, which would make traditional commodity backing (like gold or oil) or direct comparisons of economic output unreliable or impossible. A Synthetic Commodity Standard (SCS) is an artificially constructed unit of value that does not rely on naturally occurring physical goods from any single dimension. Instead, its value is derived from a basket of abstract, universally measurable properties, fundamental constants, or highly generalized forms of energy or information that can be con....
