# Introduction

#### What is mStable?

mStable is a protocol that delivers **simple, tokenized yield products** built on top of leading DeFi primitives. The goal is to make advanced strategies like **Pendle PTs** and **Aave looping** accessible through **single ERC20 tokens** that compound value automatically.

#### Mission

* Abstract away DeFi complexity into easy-to-hold tokens.
* Provide stablecoin holders with **enhanced yield**.
* Build on proven, liquid systems: **Ethena, Pendle, Aave, dHEDGE**.
* Enable scalability for **everyday DeFi users both large and small.**

#### How It Works

* **Base assets**: Credible stablecoins like Ethena’s sUSDe.
* **Yield layer**: Pendle Principal Tokens (PTs), which lock in fixed yield until expiry.
* **Amplification**: Aave looping, increasing exposure via deposit → borrow → redeposit cycles.
* **Automation**: Bots handle rollovers, rebalancing, and health factor management.
* **Output**: ERC20 tokens that **appreciate in value over time** (first flagship: **mPT-sUSDe**).

### **Quick Start**

#### Using mStable in 3 Steps

1. **Acquire the token**
   * Buy **mPT-USDe** via the mStable app.
2. **Hold**
   * The token represents a position in the strategy.
   * No manual management required.
3. **Compound automatically**
   * Behind the scenes:
     * sUSDe → PT sUSDe → Aave looping.
     * At expiry, PTs roll into the next series.
   * The token’s value increases as yields are realized.
