# About Shield ### **What is Shield?** Shield is the crypto-native solution to on-chain derivatives. Shield is building a secure, stable, and open decentralized derivatives trading protocol. ### **What price feeds does Shield integrate?** Shield integrates Chainlink, Uniswap, and Sushiswap as price feeds. The opening price is the index price. Contracts are directly interacted with dual-liquidity pools, thus replacing the complex on-chain matching calculation. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
