# VOR Introduction

This documentation covers VOR (Verified Open Randomness), which allows smart contract developers to request unpredictable, proovable randomness for their contracts, and pay for it in xFUND.

There are documentation and guides covering how to integrate the VORConsumerBase smart contract library (required for interacting with the VORCoordinator network) into your own smart contract and how to interact with the network in order to request and receive randomness in your smart contract.
