Chainlink VRF Contract Addresses

Suggest Edits

Chainlink VRF allows you to integrate provably-fair and verifiably random data in your smart contract.

For implementation details, read Introduction to Chainlink VRF.

Polygon (Matic) Mainnet

Important

The LINK provided by the Polygon (Matic) Bridge is not ERC-677 compatible, so cannot be used with Chainlink oracles. However, it can be converted to the official LINK token on Polygon (Matic) using Chainlink's PegSwap service

VRF Response Times on Polygon

VRF responses are generated after 10 block confirmations on Polygon by default. Please get in touch with us if you require VRF responses to be generated after a higher number of block confirmations, based on what you feel is best for achieving secure finality times on Polygon.
