# Pyth

[Pyth](https://pyth.network/) is the first external oracle integrated into Nabla, adding an additional security layer to our protocol for on-chain asset pricing. Leveraging Pyth's decentralized network of validators, our smart contracts seamlessly interact with the oracle to source real-time, high-fidelity market data. This integration enhances the accuracy and reliability of on-chain asset pricing, safeguarding the Backstop Pools from potential losses due to HFT pricing engine failures and mitigating market risks. 

Pythnet Price Feeds are integrated with over 12 blockchains and function as a pull oracle. Unlike push oracles, [pull oracles](https://docs.pyth.network/price-feeds/pull-updates) update on-chain prices only when requested.
