@faddat Do we want to merge this in now since it also has the v12 upgrade handler?

[faddat]

Yes

@the-frey / @vuong177 Do we want a denomination creation fee?

I set to 1 JUNO here but maybe we make it free to do so or like 0.01 juno just to prevent spam creation of denoms

[vuong177]

I think we should set it to 1 JUNO or higher.

[the-frey]

Agree that main thing is to charge something to avoid spam. Given that JUNO current value is hovering around $2 would say it's not unreasonable to be higher, but suspect that the marginal effect between say 0.1JUNO and like 10JUNO is probably negligible in terms of effect

@the-frey Currently someone could spam upload CW20s for free. Given the bank module has better queries I do feel there is less overhead overall for a chain.

Most developers will need at minimum 2 tokens most likely, one for messing around first & one for actual production. I feel keeping the barrier to entry really low to start is best course of action.

If we find lots of spam, we can gov prop to increase param as needed

[the-frey]

Yep, happy with 1JUNO as a nominal fee
