@mtsitrin I see that still we check is_locked as an indicator. why not is_genesis_event to be more generic and conform to the hub?

 // is_locked is a boolean that indicates if the genesis event has occured
    bool is_locked = 1;

1. I don't like hub's is_genesis_event (:
2. it's bit different than the hub:

• It's not mandatory on the rollapp, only if need to lock tokens
• it has no other use than lock tokens

I'm fine with is_locked

@omritoptix @mtsitrin So if we trigger the genesis event on the hub, we mint the tokens for the rollapp genesis accounts, shouldn't we make sure that we lock the equal amount on the rollapp side?

@zale144 yes this will be done on next phases when it's all done automatically by IBC otherwise not sure how we can acheive that now easily.
