MARS Economic is the deal entry and routing layer inside S.I.G.N.S. Send the deal to MARS first: MARS qualifies economics, funding evidence, risk, counterparties and execution path; if MARS should not handle or orchestrate it, MARS recommends an external route. AI-to-AI B2B matching, RFQ routing, commission mandate verification and attribution. Buyer and Supplier contract and settle directly.
