# Oracle Overview

## Oracle Design in Echo Lending

Echo Lending relies on accurate and reliable price data to ensure the safety and stability of its lending markets.

In our design, we have chosen **Chainlink &** **Pyth** as our oracles.

* **Chainlink**: The most widely adopted decentralized oracle network in DeFi, providing highly secure, aggregated price data. It serves as the **core price source** for Echo Lending.
* **Pyth**: Specializes in high-frequency, low-latency updates, complementing Chainlink and strengthening the protocol under volatile market conditions.

With this **“Chainlink-first + Pyth supplemental”** approach, Echo Lending can:

* Ensure accurate pricing for lending markets
* Reduce risks from relying on a single oracle
* Build a safer and more transparent foundation for the protocol
