What is Senthos

Senthos is a structured-products protocol built on public prediction markets. Upstream venues expose a flat universe of single-question YES/NO markets; Senthos composes that universe into three primitives: Constellations (weighted baskets of legs), Tranches(senior, mezzanine, and junior claims on a basket's terminal payout), and Principal-Protected Notes (a basket position paired with a yield sleeve sized to return principal at maturity).

All three products share a single canonical basket grid: three risk tiers (High / Mid / Low) crossed with three resolution windows (Short / Med / Long). Each basket is addressable by a stable id and is referenced directly by tranche, PPN, and portfolio surfaces. The portfolio view aggregates positions across all three products into a single list.

Motivation

A single prediction market pays out a binary outcome: the buyer receives face value if the event resolves YES and loses the premium otherwise. That shape is poorly suited to thematic exposure, diversified allocation, or defined risk/return trading. Senthos addresses this gap by introducing three derived shapes on top of the underlying market:

• Diversified exposure. A constellation holds 20–40 weighted legs in a common theme, reducing idiosyncratic variance relative to a single-market position.
• Shaped payoff.Tranches partition the basket's terminal NAV distribution into three non-overlapping claims with distinct attach and detach points.
• Capped downside. A PPN sizes a USDC yield sleeve such that compounded interest returns the deposit at maturity; only the residual basket slice is exposed to market risk.

Intended users

Senthos targets three user profiles: allocators seeking thematic exposure across many markets (Constellations), traders expressing a defined risk/return view on a basket (Tranches), and principal-sensitive depositors who require downside bounding (PPNs).
