Use Cases

    • Listen to Rare NFT auction availability (I don’t always bid on Fancy Cats..)�
  • Low traffic contract notifications
    • Life and Auto Insurance Claims
    • Sales Bonus Triggers�
  • Low cost dApp hosting
    • Cheap, off-chain dApp logic
    • Did I mention I ran this app for free?
      • Even when it costs money it is incredibly cheap!

Whats Next?

It’s up to other service providers

  • Infura
    • Could add webhook subscriptions to it’s offerings�
  • Cloud Providers (AWS, Azure, Google Cloud)
    • Could add Blockchain events as Serverless Triggers
    • Could add Blockchain events to their pub/sub and queue offerings
