# Building with uAssets

### **Integrating uAssets inside your Protocol**

The Universal Protocol provides **uAssets**, wrapped cross-chain compatible tokens that allow developers to integrate **deep liquidity and broad asset support** into their protocols. With **80+ assets** available and **Just-in-Time (JIT) liquidity via minting and redeeming**, uAssets enable protocols to offer seamless cross-chain trading, lending, and structured products **without fragmented liquidity or inefficient AMM pools**.

By integrating **Universal’s Relayer API**, developers can access **offchain order book liquidity**, ensuring **better price execution and capital efficiency** for their users. This eliminates the need for traditional LP-based models while enabling support for assets that were previously unavailable in DeFi.

***

### **How the Universal Relayer API Helps Developers**

The **Universal Relayer API** provides developers with:

* **Access to 80+ cross-chain assets** – including uBTC, uETH, uSOL, uXRP, uDOGE, and more, all [fully backed 1:1](https://www.universal.xyz/reserves) with native assets.
* **JIT Liquidity** – Liquidity is provided dynamically **at the moment of execution**, eliminating the need for deep passive AMM liquidity pools.
* **OffChain Orderbook Execution** – The API allows users to tap into **offchain order book liquidity** through the merchant network while settling transactions fully onchain.
* **Instant Minting & Redemption** – uAssets can be issued or burned as needed.
* **Composable & DeFi-Ready** – uAssets function like any ERC-20/SPL token, making them fully compatible with DEXs, lending platforms, structured products, and wallets.

### **Example Use Cases for Developers**

#### **1. OnChain Exchanges with CEX-Level Liquidity**

* Integrate uAssets into your **DEX** to offer trading pairs with **deep liquidity and tighter spreads**.
* No need for liquidity pools—**orders are fulfilled dynamically via JIT execution**.

#### **2. Cross-Chain Lending Markets**

* **Expand collateral options** by integrating uAssets like **uBTC, uSOL, uXRP, uDOGE** into lending pools.
* Remove dependency on wrapped assets with **better execution and 1:1 collateralization**.

#### **3. Derivatives & Structured Products**

* Build **options, futures, and structured products** that support **cross-chain assets**.
* Access **deep liquidity** without fragmented order books.

#### **4. Wallets with Native uAsset Support**

* Enable users to hold and trade **80+ cross-chain assets** without requiring bridges.
* Provide seamless **onboarding into DeFi** by supporting **instant swaps and conversions**.

#### **5. Liquidity Enhancement for Bridged Assets**

* Create **1:1 pools between uAssets and existing bridged assets**, improving capital efficiency.
* Reduce **slippage and price impact** for users trading cross-chain.
