# Omni-CDP

We built the first Omni-CDP protocol by integrating LayerZero's cross-chain technology. This allows users to deposit BTC on one network and mint satUSD on another, seamlessly connecting liquidity across multiple chains.

### What is LayerZero

**LayerZero** is an **omnichain interoperability protocol** that enables seamless communication between different blockchains. It allows developers to build omnichain applications (OApps) that can interact across multiple chains as if they were on a single chain.All **core protocol contracts** are **immutable** and **non-upgradeable**, ensuring you never face unplanned changes from the protocol. 

Application contract owners have the flexibility to define, customize, and lock configurations, allowing them to optimize security and cost according to their specific needs.
