event-listener
- scrapes and listens for event from a set of configured smart contracts
- Found events are handled by a set of available handlers which can write top files, DB or post to endpoints such as event-processor-api
- Stateful implementations maintain the current last block scrapped from the network
event-processor-api is a simple serverless and statelsss API
- New events are handle accordingly and persisted to Cloud DB

gcloud init and login/auth
Select create new configuration
- Select koda-eth-event-listener
