Kujira Crank

This crank app uses a single "orchestrator" account, and sets up feegrants to allow concurrent cranking of the BOW Contracts and USK Liqudiations.

Long-term this will be replaced by the on-chain scheduler. Until then, this app allows us to understand the dynamics of these crankers before committing to the scheduler.

Setup

1. Ensure that you have MNEMONIC available on your env for the orchestrator account
2. yarn
3. NETWORK=mainnet yarn start

• On first start, all the feegrants will be created which can take some time.
• Node version 19.x is required.
• Set RPC_ENDPOINT to change the default RPC.
• All workers are enabled by default, specific ones can be selected with ENABLED_WORKERS.

Export data

The crank can also export current position data as a CSV. Currently only BOW margin is supported.

Select a single worker with ENABLED_WORKERS, set EXPORT to positions (all positions) or candidates (liquidatable positions). The export can take some time.

NETWORK=mainnet ENABLED_WORKERS=bow-margin EXPORT=candidates yarn start 1> bow-margin-export.csv
