Tranche Engine

Five-tranche capital stack per living instrument with earned-yield mechanics for oracle participants.

Deployed and live across the live instrument stack.
The Green Transport D-grade exposed it: mixing depreciating EV fleet with appreciating charging infrastructure in one token is unmarketable to both growth and yield investors.

Origin

Most tokenization shops ship a single token per deal and hope every category of investor will hold it. The Green Transport D-grade in Orbital's evidence base proved that pretence wrong: depreciating EV fleet and appreciating charging infrastructure in one token is unmarketable to both growth and yield investors at the same time. The Tranche Engine was built so that a single living instrument can serve fixed-income institutions, growth investors, oracle participants, operators, and the long-term commons all from the same underlying asset, without forcing any of them to hold something they don't want.

Problem

A capital structure has to do three things at once: (a) match each cash flow to the right risk-profile counterparty; (b) make oracle accuracy directly economic so participants are paid for being right and not for being noisy; (c) prevent secondary-market speculation from extracting value the protocol intended to compound at the protocol layer. A flat single-token design fails all three.

Approach

Five named tranches per instrument, each addressing a different counterparty. Senior is bond-like — fixed yield, first claim, capped return — for institutional fixed-income allocators. Growth is equity-like — variable return from asset appreciation and residual cash flows — for growth investors. Protocol receives oracle-earned yield through an explicit accuracy-weighted formula. Operator vests against attestation quality with insurance-backed alignment, so a degrading operator is automatically clawed back. Commons captures anti-speculation NAV-premium so secondary flippers don't extract value the protocol meant to compound.

Methodology

Earned yield rewards accuracy convex over time: a participant who has been right consistently across windows earns disproportionately more than one who is right occasionally and prolifically. A surplus waterfall, governance-adjustable per instrument, distributes revenue across reserves, insurance, reinvestment, and the equity tranches in a stable order — Senior coupon first, then the equity stack. The architecture forces every cash flow to land where the right counterparty is waiting; nothing is left to flow through and out the back.
