# Gelato

> Gelato Network automates smart contract execution across major blockchains. Its products include decentralized automation, Web3 Functions, Gasless Transactions, and Gelato VRF for secure, verifiable randomness.

# VRF

Gelato VRF provides verifiable randomness for blockchain applications by utilizing Drand, a decentralized and trusted source of random numbers. It ensures that developers receive truly random values that are both provable and tamper-resistant.

See Gelato's [Documentation](https://docs.gelato.network/web3-services/vrf) guide to integrate your application with their price feeds.
