# House Liquidity Strategy

## Fixed‑Rate Engine

Institutional allocators don’t just ask *“what’s the APY?”*\
They ask *“can this yield get squeezed?”*

In standard DeFi, basis trades are often funded with **variable borrowing** (e.g., money markets whose rates spike when utilization spikes). Pair that with **variable strategy revenue**, and your margin can disappear overnight.

The House Vault is designed to reduce that risk by locking **both sides of the ledger**:

* **Fixed revenue** via **Pendle Principal Tokens (PTs)**
* **Fixed cost of capital** via **Morpho fixed‑rate borrowing**

Together, this creates a TradFi‑style **Net Interest Margin (NIM)** engine: the spread between what the Vault earns and what it pays is structurally more predictable.

***

### What happens when you deposit USDC

The Vault does not simply hold raw stables or chase variable‑rate farms. It structures capital into a **delta‑neutral, fixed‑rate portfolio** with liquidity buffers.

If you inspect the Vault, you’ll see a basket of **Pendle PT positions**, **Morpho fixed‑rate margin**, and baseline liquid yield assets.

***

### Portfolio building blocks

#### 1. **PT‑nHYPE: Fixed‑yield basis trade**

* **What it holds:** Pendle **PTs** for **nHYPE**
* **The strategy (high level):** execute a delta‑neutral basis position (**Long spot HYPE / Short HYPE‑Perp**), mint **nHYPE**, then split on Pendle into **PT‑nHYPE + YT‑nHYPE**
* **The institutional edge:** the Vault can sell **YT‑nHYPE** to participants who want the variable yield/points stream, while holding **PT‑nHYPE** to maturity to lock a fixed‑rate principal redemption profile

#### 2. **Morpho fixed‑rate margin: locked cost of capital**

* **What it holds:** fixed‑rate borrowing positions via **Morpho**
* **Why it matters:** variable borrow rates (e.g., utilization spikes) are how profitable basis trades get squeezed
* **The institutional edge:** by funding margin at a **fixed rate**, the Vault stabilizes its cost of capital—so strategy returns aren’t silently eaten by borrow‑rate volatility

> Pendle PTs lock the **asset yield** side.\
> Morpho fixed‑rate borrowing locks the **liability** side.\
> That pairing is the core NIM mechanism.

#### 3. **PT‑nLP: Fixed‑rate market making via ABM**

* **What it holds:** Pendle **PTs** for **nLP** (Nunchi Liquidity Provider)
* **The strategy (high level):** allocate stables to fund the **Agentic Binned‑liquidity Manager (ABM)**, then split nLP on Pendle into **PT‑nLP + YT‑nLP**
* **The institutional edge:** market‑making revenue can vary day‑to‑day with volume/volatility; selling **YT‑nLP** transfers that variable upside to speculators, while holding **PT‑nLP** targets a more predictable, fixed‑rate return profile for House LPs

#### 4. **Baseline yield assets: liquidity + floor**

* **What it holds:** liquid, high‑quality stable yield positions (e.g., **sDAI** and similar receipt tokens)
* **Why it holds them:** maintain withdrawal buffers and earn a “floor” yield on capital not currently allocated to PT structures

***

### Why this is institutional‑grade

The House Vault is built around a simple principle: **don’t promise stability while holding unhedged variable rates**.

By pairing **PT‑locked revenue** with **fixed‑rate margin**, the Vault is designed to:

* reduce “squeeze risk” from borrow spikes
* reduce day‑to‑day variance from variable yield streams
* separate market roles cleanly: **Players** buy volatility (YTs), **House LPs** hold fixed‑rate exposure (PTs)

***

### Risk notes

This design reduces variance—it does not eliminate risk. Users should understand smart contract risk, peg risk on stable collateral, basis/hedge risk, market discontinuities, integration dependencies (Pendle/Morpho), and liquidity conditions.

Nothing here is financial advice or a guarantee of returns.
