# Protocol Overview

**Moar Market** is an undercollateralized leverage lending protocol built on Aptos. It allows users to borrow from multiple isolated pools using a unified Credit Account, while enforcing strict solvency rules based on real-time oracle pricing.

***

### 💼 Credit Accounts

At the core of Moar lies the **Credit Account** — a user-owned smart account that holds assets and tracks liabilities. Each user can have multiple Credit Accounts.

**Features:**

* Borrow from multiple pools simultaneously
* Hold multiple assets
* Interact with DeFi strategies
* Enforce solvency on every action

All borrowing, transferring, and strategy interactions are routed through these accounts.

***

### 🧮 Health Check & Solvency

Every Credit Account must remain **healthy** after any operation that moves funds out. Health is determined by comparing the total asset value against the minimum required value derived from debt and pool-specific LTVs.

Let:

* `Dp` = debt from pool `p`
* `LTVpa` = LTV for asset `a` in pool `p`

Then:\
**Minimum required asset value** = ∑ (Dp / LTVpa)

A Credit Account is healthy if its total asset value (from oracle prices) is **greater than or equal** to this threshold.

***

### 📊 LTV & Leverage

Each (pool, asset) pair defines its own **Loan-to-Value (LTV)** ratio.

Leverage is derived as:\
**Leverage = LTV / (1 - LTV)**

Varying LTVs allow pools to tune risk across different assets.

***

### 🏦 Lending Pools

Lending pools are isolated by design. Each pool can independently define:

* Interest rate model
* Supported assets and LTVs
* Fee-on-interest
* Liquidation parameters

Lenders earn interest from borrowers based on pool utilization.

***

### 🔄 Yield Strategies

Credit Accounts can optionally deploy assets into whitelisted **yield strategies**, such as:

* **Hyperion** (CLMM vaults)
* **Panora** (stable swap)
* **Thala** (AMMs, LSDs)

Each strategy is tightly integrated and permissioned. Solvency is enforced before and after any strategy interaction.

***

### 📈 Interest Rate Model

Pools use kinked interest rate curves defined by:

* Base rate
* Slope below kink
* Slope above kink
* Kink utilization point

Supply APR is derived from real borrow interest after deducting protocol fees (`fee_on_interest`) and scaled by utilization.

***

### 🔍 Tiered Oracle

Moar uses a multi-source **Tiered Oracle** for robust asset pricing. The system:

* Aggregates prices from DEXes and external feeds
* Enforces freshness checks
* Uses tiered fallback logic for resiliency

Oracle prices are critical to health checks and liquidations.

***

### ⚠️ Liquidations

If a Credit Account becomes **unhealthy**, it can be liquidated.\
Liquidations are currently **permissioned**, meaning only approved liquidators can execute them.

**Process:**

* Liquidator repays part of the debt
* Receives discounted collateral from the account

All valuations use real-time oracle pricing.

***

### 🧩 Modular Architecture

Moar is built for composability and growth.

* New strategies are integrated via external **strategy adapters**
* Adapters follow a standard interface, ensuring secure plug-and-play design
* Once deployed and enabled, strategies can be used without core upgrades
* Moar can integrate with any DeFi protocol on Aptos — AMMs, vaults, LSDs, etc.

This modularity gives Moar the power to evolve with the ecosystem and unlock new forms of capital efficiency.
