+RedStone Finance offers modular, cross-chain Oracle solutions tailored for DeFi applications. With compatibility across EVM and non-EVM ecosystems, RedStone empowers developers to access accurate, real-time, and customizable data feeds for diverse use cases such as DEX pricing, yield-bearing collaterals, and staking protocols. 
+
+The system emphasizes scalability, cost-efficiency, and flexibility, leveraging technologies like Arweave for data archiving.
+
+## **Core Features**
+1. **Oracle Models**:
+   - **Pull Model**: Low gas costs with dApps fetching signed data on-demand.
+   - **Push Model**: Traditional oracle system with dApps controlling update conditions.
+   - **X Model**: Zero-latency feeds, ideal for derivatives like perpetuals and options.
+
+2. **Types of Data Feeds**:
+   - **Market Feed**: Prices from exchanges (e.g., ETH/USD).
+   - **Contract Rate Feed**: Ratios derived from smart contracts (e.g., stETH/wstETH).
+   - **Proof of Reserve**: Verifies assets backing issued tokens (e.g., NAV feeds).
+   - **Real-World Data**: Institutional data like staking yields.
+
+3. **Supported Chains**:
+   RedStone operates across 
+   - Ethereum, 
+   - Avalanche, 
+   - Polygon, 
+   - StarkNet, 
+   And other chains, ensuring seamless integration for diverse blockchain ecosystems.
