# Pyth

> Pyth Network is a decentralized oracle providing pricing data and verifiable random functions (VRF) for smart contracts. By sourcing data directly from institutional providers, Pyth ensures secure, low-latency price updates while maintaining transparency and efficiency.

# Price Feeds

Pyth Network provides real-time financial market data to smart contracts across 100+ blockchains, sourcing prices from over 100 exchanges and market makers. With 850+ price feeds covering equities, commodities, and cryptocurrencies, Pyth aggregates and updates prices multiple times per second.

See Pyth's [Documentation](https://docs.pyth.network/price-feeds/price-feeds) guide to integrate your application with their price feeds.

# VRF

Pyth Entropy(VRF) service enables on-chain generation of provably fair random numbers. To integrate Pyth Entropy, you need to invoke an on-chain function to request a random number from Entropy. This function accepts a randomly generated number, which can be created off-chain and sent to the Entropy contract. In return, the contract provides a sequence number. Once the request is processed, Pyth Entropy will send a callback to your contract, delivering the generated random number.

See Pyth's [How to Generate Random numbers in EVM dApps](https://docs.pyth.network/entropy/generate-random-numbers/evm) guide to integrate your application with Pyth Entropy.
