sbt-ethereum tasks related to the configuration and state of Ethereum and compatible network nodes, via which sbt-ethereum interacts with a blockchain.
There must also be a node URL available for that chain ID.
ethNode* commands allow you to configure which Chain ID your session will be associated with, and specify node URLs, scoped to a particular chain ID. You can configure node URLs for all the different chains you interact with, as long as they have unique EIP-155 Chain IDs.
You can also check the availability and state of the currently configured node.
Contacts the currently configured node URL and checks the current block number.
This is very useful as a “ping”, just to test that a node is available.
