Issue Description

I would expect it is possible to set a custom genesis configuration when creating a new hyperchain (ie. what contracts are predeployed, what balances are already set, etc...). However, I am not immediately clear how to do so, or even if it is supported.

Expected Behavior

A Zk Stack chain operator should (might?) be able to set a custom genesis config for their hyperchain.

Current Behavior

This does not seem possible, or I missed it.

Hi @ETeissonniere,

Currently custom genesis file for state migration is not supported, but we plan to add support in the future.
