starknet.events index
This index allows processing events emitted by Starknet smart contracts. You can define a handler for each contract/name pair. Only necessary events are processed.
Below is a basic indexer for USDt token contract transfers.
To create a project based on this template, run dipdup new -t demo_starknet_events.

Datasources
DipDup indexes for Starknet use Subsquid Network as a main source of historical data. Starknet nodes are not required for DipDup to operate, but in future updates, it will be possible to use them to get the latest data (not yet in Subsquid Network) and realtime updates. See starknet.subsquid page for more info on how to configure the datasource.
