How to set up VRF proxy?

VRF (Verifiable Random Function) capabilities are essential for any customer looking to launch a gaming application. Historically, building a VRF is difficult on blockchains because of the inability to leverage a RNG (Random Number Generator) on-chain. AvaCloud provides a VRF solution via its portal to help customers to overcome this difficulty.
