# 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.
