Create a Fallback VRF

PreviousCreate a VRF TaskNextMigrating from Chainlink VRF

Last updated 3 days ago

Fallback VRF is a mechanism designed to fulfill missing or unfulfilled VRF requests. By creating a fallback task alongside your main VRF task, you can ensure that all requests are fulfilled in any scenario.

Setting up a fallback task for VRF is a straightforward process. Here’s a step-by-step guide to help you create one.

1. Deploy VRF Compatible Contract

Before deploying Fallback VRF, ensure that your contract is compatible with VRF. You can quickly set up one by heading over to the quick start guide.

2. Select Deployment Network

Navigate to the Gelato app and ensure you choose the same network where both your Main VRF task and VRF compatible contracts are deployed.

3. Enter Fallback Parameters

Fallback VRF has three main parameters:

  • From Block: The block number from which the fallback will start analyzing missing events. It is recommended to use the block number of your VRF-compatible contract deployment.

  • Time: The interval at which the fallback task checks for missing events.

  • Contract Address: The address of your deployed VRF-compatible contract.

4. Launch your Fallback VRF Instance

Once all details are correctly entered, go ahead and launch your Fallback Gelato VRF instance.
