Gelato
Gelato provides access to Verifiable Random Functions (VRF) on zkSync. VRFs are cryptographic primitives that generate pseudorandom numbers in a way that is provably secure and verifiable. A VRF allows a holder of a private key to produce a random number along with a proof that the number was generated legitimately (making it publically verifable). More information, including how to use VRFs in your dApp, can be found in the Gelato docs.
