Supported Networks

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

For implementation details, read Introduction to Chainlink VRF.

Coordinator parameters

These parameters are configured in the coordinator contract. You can view these values by running getConfig on the coordinator or by viewing the coordinator contracts in a blockchain explorer.

• uint16 minimumRequestConfirmations: The minimum number of confirmation blocks on VRF requests before oracles respond
• uint32 maxGasLimit: The maximum gas limit supported for a fulfillRandomWords callback.
• uint32 stalenessSeconds: How long the coordinator waits until we consider the ETH/LINK price used for converting gas costs to LINK is stale and use fallbackWeiPerUnitLink
• uint32 gasAfterPaymentCalculation: How much gas is used outside of the payment calculation. This covers the additional operations required to decrement the subscription balance and increment the balance for the oracle that handled the request.
