@furkanahmetk Thank a lot for the PR! 🙏 We will review it and give feedback or merge it.

@darthsiroftardis or @sacherjj Could you please take a look?

Can someone explain the use case for when a transaction hash is not specified

[mrkara]

@darthsiroftardis No idea. Looks like an oversight to me.

@furkanahmetk Let's just:

• Remove the no-parameter case
• Make sure the command with a hash works fine
