Inspired by The Big Short: any user can walk up to NEXUS and create a bespoke financial instrument from a thesis, on the fly. **The Vision:** Users describe a thesis in plain English ("I think shipping disruption will crush ZIM and DAC but boost domestic steel"). NEXUS validates the thesis using Tuatara vector signals, constructs the instrument mechanics, deploys it on-chain, and tokenizes it for secondary trading. Other users can invest alongside or take the other side. **Three Instrument Types:** 1. **Basket Spread** — long one basket, short another, payoff = performance differential at expiry 2. **Threshold Trigger** — pays if composite index crosses a threshold, variable premium 3. **Synthetic CDS** — small premium, massive upside (up to 15x+) if thesis plays out. The Baum trade. **Key Features:** - NEXUS is the desk — conversational instrument creation, not form-based - Tuatara validates theses and discovers hidden asset relationships the market is blind to - Naked positions — bet on outcomes without holding the underlying - Asymmetric payoff structures — small premium, huge upside - On-chain deployment via InstrumentFactory (EIP-1167 Clone pattern) - Secondary market trading via existing CLOB/AMM - User capital only — never platform funds **Architecture:** 4 phases — Data model + services, Smart contracts (PAVInstrumentFactory.sol), NEXUS tool integration (7 new tools), Frontend (marketplace, detail, builder pages). **Revenue:** $5 creation fee + trading fees on secondary market + performance fees.
