 --l1-rpc - The RPC url required to pull data from L1.
---update-verification-key - Specifes if the verification key should be updated from [github](https://github.com/matter-labs/era-contracts/blob/main/tools/data/scheduler_key.json).
 --json - Flag to specify if the output should be in json. Note that all the usual std out prints are silenced.
