# Welcome to StableUnit 101
**One-Liner**
**StableUnit** is a CDP protocol **with two complementary products:**
1. **USD Pro** – a $1‑pegged, yield‑bearing stablecoin that auto‑grows in your wallet from [three on‑chain revenue streams](/documentation/introduction/how-does-it-work.md);
2. **StableUnit lending** – allows to borrow stablecoins against LPs, yield‑optimizers positions **without giving up your farming rewards**.
### **Overview**
* **USD Pro** is the first fully DeFi‑compatible, yield‑bearing stablecoin that never rebases or drifts above its peg. Built on the battle‑tested MakerDAO core, it trades 1:1 with USDC or USDT anywhere, but quietly compounds yield sitting in your wallet—no staking, no claims, zero clicks. Need to offramp? Swap it for USDC/USDT instantly.
* **StableUnit lending —** a permissionless market letting you borrow stables using productive collateral—plain ETH/WBTC, Uniswap V3 or Balancer LP tokens, Pendle/Aura receipts, and soon cross‑chain bridge liquidity. Your collateral keeps earning; the protocol never touches your yield. You can leverage, loop, or just borrow paying an ultra‑competitive borrow rate.
**Analogy**
*While your collateral keeps farming, think of USD Pro as a high-yield savings account in your pocket. Just by holding it, your balance grows every block and outperforms typical RWA‑stablecoins.*
### **Quick Start**
Basics on [**How does it work**](/documentation/introduction/how-does-it-work.md) page
See the difference on [**Why StableUnit**](/documentation/introduction/why-stableunit.md) page
See [**Getting Started**](/documentation/introduction/getting-started.md) for a step-by-step guide on acquiring **USD Pro** on supported exchanges (e.g. Uniswap) or borrow in the StableUnit dApp and earning passive yield.
See [**Governance & Tokenomics**](/documentation/governance/tokenomics-and-vote-escrow-ve-utility.md) to participate in StableUnit DAO and contribute to governance, propose upgrades, or build on our open-source smart contracts.
See [**Architecture**](/documentation/architecture/conceptual-overview.md) section to learn more on how to build on StableUnit. DeFi builders can integrate USD Pro into lending, trading, or payments just as they would any ERC-20 token.
