Data flow

In order to start indexing all whitelisted Lockup contracts we need a genesis event. With Sablier V2, there is no factory pattern so we couldn't rely on a data source contract. The next best things for a "genesis" point were:

  1. Relying on the Comptroller whitelisting the first contract
  2. Relying on the first event triggered by the earliest registered on-chain contract

To reduce the number of dependencies required to kickstart a subgraph, we chose to rely on the second approach. Therefore, when setting up a deployment, you'll need to follow a few rules.
